Galactostasis / Milk Retention

Galactostasis, commonly known as milk retention or caked udder, is a condition affecting lactating or pseudopregnant female rabbits in which milk accumulates in the mammary glands and is not properly expressed or reabsorbed. This condition causes the mammary tissue to become engorged, painful, and potentially susceptible to infection. While galactostasis itself is not immediately life-threatening, it causes significant discomfort and, if left untreated, can progress to mastitis, a serious bacterial infection of the mammary glands that requires aggressive medical intervention.

The condition develops when milk production exceeds the rate at which milk is removed from the mammary glands. This imbalance can occur in several situations: when a nursing doe loses some or all of her kits, when kits are weaned abruptly rather than gradually, when a doe experiences pseudopregnancy with accompanying milk production, or when kits are unable to nurse effectively due to illness or weakness. Does with large litter sizes may be particularly prone to galactostasis if kit numbers suddenly decrease, as their milk production has ramped up to meet the demands of many nursing kits.

The impact of galactostasis on the affected doe includes significant discomfort and pain in the mammary area, potential changes in behavior including reluctance to move or lie down normally, and reduced appetite that can trigger secondary gastrointestinal stasis. The engorged mammary glands are warm and firm to the touch, and the doe may be protective of her underside or show signs of pain when handled. If bacteria gain entry to the milk-filled glands, the condition can rapidly progress to infectious mastitis, which presents a much more serious threat to the doe's health and potentially her life.

Treatment of galactostasis focuses on reducing milk production, relieving engorgement, preventing infection, and providing supportive care to keep the doe eating and comfortable. Prompt recognition and treatment by a rabbit-savvy veterinarian typically results in good outcomes. However, because rabbits hide signs of illness and pain, owners may not notice early signs of mammary problems, and the condition may be fairly advanced by the time it is recognized. Understanding the risk factors for galactostasis and monitoring at-risk does closely allows for early intervention and better outcomes.

The primary cause of galactostasis is an imbalance between milk production and milk removal from the mammary glands. Under normal circumstances, nursing kits stimulate ongoing milk production through their suckling, and the milk is continuously produced and consumed in balance. When this equilibrium is disrupted, milk accumulates in the mammary glands faster than it can be removed. The most common trigger is sudden reduction in nursing, which can occur when kits die, when the doe rejects her litter, when kits are removed for hand-rearing, or when weaning happens too abruptly. The doe's body continues producing milk at the previous rate even though demand has decreased or ceased entirely.

While galactostasis is not genetically determined, certain factors related to individual does may predispose them to developing the condition. Does who are heavy milk producers are at greater risk simply because they have more milk to accumulate. First-time mothers may be more likely to experience nursing difficulties that lead to milk retention. Does who have had previous episodes of galactostasis or mastitis may be predisposed to recurrence. Hormonal variations between individual does can affect both milk production rates and the ability of the mammary tissue to involute (return to non-lactating state) when nursing ceases.

Environmental and management factors play significant roles in the development of galactostasis. Abrupt weaning practices, where kits are removed suddenly rather than being allowed to naturally reduce nursing frequency over time, commonly trigger the condition. Stressful housing conditions can affect both the doe's milk letdown and the nursing behavior of kits. Loss of kits due to environmental factors such as temperature extremes, predator stress, or inadequate nesting materials leaves the doe with full mammary glands and no kits to nurse. Poor nutrition during lactation can affect milk quality and kit nursing behavior. Overcrowded conditions or competition for nursing access in very large litters may result in some mammary glands receiving less stimulation and becoming engorged.

Risk factors for galactostasis include any situation that results in decreased nursing demand. Does who lose their entire litter, whether to stillbirth, neonatal death, or removal for hand-rearing, are at highest risk. Partial litter loss also creates risk, particularly if the remaining kits do not nurse from all available teats. Weak, ill, or premature kits may nurse ineffectively, leading to incomplete milk removal. Pseudopregnancy, a hormonally driven false pregnancy where the doe develops mammary tissue and may produce milk despite not being pregnant, can result in galactostasis even without any kits present. Does separated from nursing kits for extended periods, such as for veterinary care or travel, may develop engorgement.

The mechanism of galactostasis development involves hormonal and physical processes within the mammary tissue. During normal lactation, the hormone prolactin stimulates milk production, while the physical act of nursing triggers oxytocin release that causes milk letdown. When nursing ceases, prolactin levels should decrease and the mammary glands should undergo involution, a process where milk-producing cells die off and the remaining milk is reabsorbed. However, this process takes time, and milk continues to be produced for a period after nursing stops. If the accumulated milk is not removed by nursing, hand-expression, or absorption, the mammary glands become distended and painful. The stagnant milk provides an ideal medium for bacterial growth if contamination occurs, and the stretched, damaged mammary tissue is more vulnerable to infection.

Early warning signs of galactostasis may be subtle, particularly since rabbits instinctively mask signs of discomfort. Attentive owners may notice the doe becoming reluctant to lie down in her usual positions or shifting frequently while resting. A nursing doe who begins avoiding her kits or resisting their attempts to nurse may be experiencing mammary discomfort. Subtle changes in appetite or activity level can precede more obvious symptoms. The doe may be protective of her underside or react when touched near the mammary area. Changes in grooming behavior, particularly decreased attention to the ventral abdomen, can indicate discomfort in that region. Any behavioral change in a recently kindled or pseudopregnant doe warrants closer examination of the mammary glands.

Common symptoms of established galactostasis are more readily apparent upon physical examination. The affected mammary glands become visibly enlarged, sometimes dramatically so, with the tissue feeling firm, warm, and tense when palpated. One or more glands may be affected, and the involvement may be asymmetric. The overlying skin may appear stretched and shiny, and superficial blood vessels may be more visible than normal. Milk may leak from the teats, or conversely, the teats may appear tight and occluded. The doe typically shows signs of discomfort when the affected glands are touched, and the entire ventral abdomen may appear swollen and abnormal.

Behavioral changes associated with galactostasis reflect both the pain of engorgement and potential developing illness. Reduced appetite is common and particularly concerning in rabbits due to the risk of secondary gastrointestinal stasis. The doe may drink less than normal or, conversely, increase water consumption. Activity levels typically decrease, with the doe preferring to remain still rather than hop and explore. A normally social doe may become withdrawn or irritable. Changes in litter box habits, including reduced fecal output, smaller or misshapen pellets, or changes in cecotrope production, can indicate both direct discomfort and developing GI complications. Teeth grinding, a sign of pain in rabbits, may be heard. The doe may adopt a hunched posture or press her abdomen against the cage floor in apparent attempt to relieve pressure.

Physical signs upon examination confirm the diagnosis of galactostasis. Palpation of the mammary chain reveals distended, firm glands that may feel lumpy or uniformly swollen. The tissue is typically warm to the touch. Gentle pressure may express milk from the teats, though this should be done carefully to avoid causing additional discomfort or introducing infection. The doe's body temperature should be checked, as fever indicates possible progression to mastitis. The skin over the affected glands should be examined for redness, wounds, or signs of tissue breakdown. Lymph nodes near the mammary tissue may be enlarged if inflammation is significant.

Symptom progression from uncomplicated galactostasis to mastitis follows a recognizable pattern. Initially, the glands are enlarged but the doe remains relatively bright and maintains her appetite. Without intervention, the engorgement worsens and pain increases, leading to behavioral changes and reduced eating. If bacteria colonize the stagnant milk, the glands become increasingly hot, red, and painful. The doe may develop fever, marked lethargy, and complete loss of appetite. The milk may become discolored or blood-tinged, and abscesses may form within the mammary tissue. Left untreated, systemic infection can develop.

Emergency symptoms requiring immediate veterinary attention include any signs suggesting mastitis or systemic infection. Fever, severe lethargy, complete refusal to eat, or absence of fecal output for more than 12 hours constitute emergencies. Mammary tissue that becomes purple, black, or develops open wounds requires urgent care. Discharge from the teats that is bloody, green, or foul-smelling indicates infection. If the doe shows signs of sepsis, including pale or bluish mucous membranes, rapid breathing, weak pulse, or collapse, emergency veterinary care is critical. Open-mouth breathing is always a dire emergency in rabbits regardless of the underlying cause.

Initial examination for suspected galactostasis begins with a thorough history and physical assessment by a rabbit-savvy veterinarian. Important history questions include the doe's recent reproductive status, dates of kindling if applicable, the number and fate of kits, weaning practices used, whether the doe has shown signs of pseudopregnancy, and any previous mammary problems. The physical examination includes assessment of vital signs, with particular attention to temperature which helps distinguish simple engorgement from infectious mastitis. Complete examination of all mammary glands is essential, as multiple glands are often affected even if only some are obviously enlarged. The veterinarian will assess the degree of engorgement, tissue consistency, temperature and color of the affected glands, and the doe's pain response to palpation.

Diagnostic tests help characterize the severity of galactostasis and identify any complications. If infection is suspected, the veterinarian may collect a milk sample from the affected glands for cytology and bacterial culture. Cytology examines the cells present in the milk and can reveal inflammatory cells indicating infection. Culture identifies the specific bacteria involved and determines antibiotic sensitivity, guiding treatment choices. Blood work including complete blood count may be recommended, as elevated white blood cell counts suggest infection. Blood chemistry helps assess overall health status and organ function. In cases where abscess formation is suspected, ultrasound imaging can help visualize the internal structure of affected glands and identify fluid pockets that might require drainage.

Differential diagnosis for mammary gland enlargement in does includes several conditions that must be distinguished from simple galactostasis. Mastitis, bacterial infection of the mammary glands, represents a progression from galactostasis and is identified by more severe local and systemic signs including fever. Mammary tumors, though less common in rabbits than in some other species, can cause gland enlargement and must be considered, particularly in older does. Abscesses in the mammary region may arise from trauma, bite wounds, or bacterial seeding from other sources. Mammary hyperplasia or dysplasia are abnormal tissue changes that can affect gland size and consistency. Careful examination and diagnostic testing differentiate these conditions from galactostasis.

Diagnosis confirmation of galactostasis is typically based on the combination of history, physical findings, and response to treatment. The classic presentation of a doe with recent nursing cessation or pseudopregnancy, combined with firm, enlarged, warm mammary glands without fever or severe systemic signs, is diagnostic for uncomplicated galactostasis. The diagnosis is supported by successful treatment with milk reduction strategies and supportive care. If the condition does not respond appropriately to treatment, or if the doe deteriorates, additional diagnostic testing may be needed to identify complications or alternative diagnoses. Culture results, if obtained, guide ongoing antibiotic therapy if infection is present.

Emergency and immediate treatment for galactostasis focuses on reducing engorgement, preventing progression to mastitis, and providing pain relief. Pain management is essential and typically involves meloxicam, a rabbit-safe non-steroidal anti-inflammatory drug that provides both pain relief and anti-inflammatory effects. Initial assessment of the doe's hydration status and gut function guides supportive care decisions. If the doe has reduced her food intake, gut motility support may be needed to prevent or treat secondary gastrointestinal stasis. Syringe feeding with herbivore critical care formula should be initiated if the doe is not eating adequately on her own, as maintaining gut function is critical in rabbits. Subcutaneous fluids may be administered if dehydration is present.

Medical management of galactostasis aims to reduce milk production and relieve existing engorgement. The approach to engorgement management must be carefully considered, as aggressive milk expression can actually stimulate continued production. Limited, gentle expression of small amounts of milk may provide some relief without significantly prolonging lactation, but this must be balanced against the risk of stimulating further production. Application of cold compresses to the affected glands can reduce swelling and provide comfort. The hormone cabergoline, a prolactin inhibitor, may be prescribed to suppress ongoing milk production, though its use in rabbits is off-label and requires veterinary supervision. Diuretics are sometimes used to help reduce fluid accumulation. If bacteria are cultured from the milk or if mastitis is suspected, appropriate rabbit-safe antibiotics such as enrofloxacin, trimethoprim-sulfamethoxazole, or chloramphenicol are prescribed.

Surgical intervention is rarely needed for uncomplicated galactostasis but may become necessary if complications develop. Abscesses that form within infected mammary tissue may require surgical drainage and flushing. In severe cases of mastitis that do not respond to medical management, surgical debridement of necrotic tissue or mastectomy (removal of affected gland) may be necessary. Rabbit anesthesia carries inherent risks, and these procedures should only be performed by veterinarians experienced with rabbit patients. Importantly, rabbits should not be fasted before anesthesia, unlike dogs and cats, as fasting can trigger dangerous gastrointestinal stasis.

Supportive care is crucial throughout treatment and recovery from galactostasis. Nutritional support receives top priority, as any illness or pain can cause rabbits to reduce food intake, quickly leading to hepatic lipidosis and GI stasis. Fresh grass hay should be available continuously, and the doe should be encouraged to eat with offerings of her favorite greens and herbs. If voluntary intake is inadequate, syringe feeding with critical care formula must be performed multiple times daily. Hydration support through fresh water availability and subcutaneous fluid administration if needed helps maintain body functions. The doe should be housed in a warm, quiet, comfortable environment with soft, clean bedding. Activity should be allowed as tolerated, as gentle movement supports gut motility and overall well-being.

Alternative and complementary approaches may support recovery alongside conventional treatment. Gentle, warm compresses applied to affected glands may help with milk flow if gentle expression is being attempted, while cool compresses reduce inflammation. Sage tea or dried sage offered as an herb is traditionally thought to help reduce milk production, though scientific evidence in rabbits is limited. Cabbage leaves applied to engorged glands is a folk remedy used in various species that some owners find helpful. Gentle massage of the abdomen, away from the mammary area, can help stimulate gut motility. Ensuring the doe has appropriate exercise space encourages movement that supports digestive function.

Treatment decisions should involve discussion between the owner and veterinarian regarding the doe's overall condition, prognosis, intended future use for breeding, and practical considerations. Most cases of uncomplicated galactostasis respond well to conservative management with pain relief, milk reduction strategies, and supportive care, with resolution expected within days to a couple of weeks. Cases complicated by mastitis require more intensive treatment and carry a more guarded prognosis. Financial considerations should be discussed, as treatment of complications can become costly. Quality of life assessment is essential throughout treatment, and humane euthanasia may be appropriate in severe cases where the doe is suffering and prognosis is poor.

Recovery timeline for galactostasis varies depending on the severity of engorgement and whether complications developed. Uncomplicated galactostasis typically shows improvement within 2-4 days of initiating treatment, with complete resolution expected within 1-2 weeks as the mammary tissue involutes and milk production ceases. The first sign of recovery is usually improvement in the doe's comfort level, reflected in increased activity and normalized eating and drinking patterns. The mammary glands gradually become less firm and swollen, though complete return to normal appearance may take longer than resolution of clinical signs. Cases complicated by mastitis require longer treatment and recovery periods, potentially several weeks, depending on the severity of infection.

Post-treatment care focuses on monitoring for complete resolution and preventing recurrence. Any prescribed medications, particularly antibiotics if infection was present, should be completed as directed even if the doe appears fully recovered. The mammary glands should be checked daily initially, then every few days, until complete involution is confirmed. Continued attention to the doe's appetite and fecal output ensures that gut function remains normal throughout recovery. The doe should be kept comfortable and stress-free during recovery, with appropriate housing, diet, and gentle handling. Follow-up veterinary appointments may be recommended to confirm resolution and address any concerns.

Prognosis factors for galactostasis include the promptness of treatment, whether infection developed, and the doe's overall health status. Uncomplicated galactostasis caught early and treated appropriately carries an excellent prognosis, with complete recovery expected. Does who develop mastitis have a more guarded prognosis, particularly if abscesses form or if treatment is delayed. Severe mastitis with tissue necrosis can be life-threatening and may result in permanent damage to affected mammary glands even with successful treatment. Does who experience GI stasis secondary to galactostasis face additional risks until gut function is fully restored. Individual factors including the doe's age, body condition, and any concurrent health issues influence recovery.

Long-term outlook following galactostasis depends on whether permanent mammary damage occurred and whether the doe will be bred again. Does who recover completely from uncomplicated galactostasis can typically be bred again without increased risk, though careful management of any future litters and weaning is recommended. Glands that were severely affected or that developed abscessation may have reduced function in future lactations. Does who required surgical intervention may have limited or absent function in operated glands. For does not intended for breeding, spaying eliminates the risk of future reproductive complications including pseudopregnancy-associated galactostasis. Recording detailed notes about the episode and management helps guide decisions about future breeding.

Primary prevention of galactostasis centers on management practices that minimize the risk of sudden nursing cessation. When possible, weaning should be gradual rather than abrupt, allowing the doe's milk production to decrease in response to reduced demand. A typical gradual weaning approach involves separating kits from the doe for increasingly long periods over several days to a week before permanent separation. If kits must be removed suddenly due to emergency circumstances, close monitoring of the doe's mammary glands and prompt intervention if engorgement develops can prevent complications. Does who lose part of their litter should be monitored for engorgement of the glands no longer being nursed by the remaining kits.

Environmental prevention focuses on supporting successful nursing and healthy litters, thereby reducing the likelihood of circumstances that trigger galactostasis. Proper nest box setup with appropriate bedding materials helps keep kits warm and viable. Temperature control in the kindling area prevents losses due to cold exposure of newborns or heat stress of the doe. Protecting the doe from predators, loud noises, and other stressors reduces the risk of kit neglect or death. Ensuring the doe has adequate nutrition during pregnancy and lactation supports milk quality and quantity as well as kit vigor and survival. Clean housing and good hygiene reduce infection risk for both doe and kits.

Dietary considerations for lactating does support healthy nursing and appropriate milk production. A lactating doe has increased nutritional needs and should receive high-quality pellets in greater quantities than maintenance feeding, typically provided free-choice during peak lactation. Unlimited grass hay remains essential for digestive health. Fresh greens and vegetables provide additional nutrients and hydration. Clean, fresh water is critical, as lactating does have greatly increased water requirements for milk production. Avoid dietary changes during lactation that might affect milk composition or the doe's gut health. After weaning, gradually reduce pellet quantities to help signal the doe's body to decrease milk production.

Health maintenance practices support overall reproductive health and reduce galactostasis risk. Pre-breeding health assessment ensures does are in good condition before mating. Regular observation of nursing does allows early detection of problems such as inadequate milk supply, kit weakness, or early mammary engorgement. Does showing signs of pseudopregnancy, characterized by nest building and mammary development without kindling, should be monitored for milk production and potential galactostasis even without nursing kits. Regular veterinary care with a rabbit-savvy veterinarian provides guidance on breeding management and early intervention when problems arise.

Early intervention when risk factors are present can prevent full-blown galactostasis. When circumstances require sudden removal of kits, such as for hand-rearing orphans or separating an aggressive doe from her litter, the doe should be monitored closely for signs of engorgement starting within hours of kit removal. If engorgement is detected early, consultation with a veterinarian can guide management decisions about whether limited expression, cold compresses, or medical intervention to reduce production is most appropriate. Does who have experienced previous episodes of galactostasis should be monitored especially closely in future reproductive cycles. Having an established relationship with a rabbit-savvy veterinarian ensures access to guidance when questions arise.

Daily management of does at risk for or recovering from galactostasis requires attentive monitoring and supportive care. Daily health checks should include gentle palpation of the mammary glands to assess size, consistency, warmth, and the doe's pain response. Food and water intake should be tracked, with any decrease from normal consumption noted and addressed promptly. Litter box monitoring reveals changes in fecal output that might indicate developing GI stasis secondary to pain or reduced eating. The doe's activity level, posture, and overall demeanor provide information about her comfort and recovery progress. Any changes from the previous day should be noted, and concerning changes should prompt veterinary consultation.

Home environment considerations for does with mammary conditions focus on comfort and cleanliness. Soft, clean bedding material provides cushioning for sensitive mammary tissue and reduces contamination risk. Bedding should be changed more frequently than usual to maintain hygiene and prevent bacterial contamination of the mammary area. The enclosure should be kept at a comfortable temperature, avoiding heat stress which can compound the doe's discomfort. A quiet location away from household stressors supports recovery. If the doe is normally housed with a companion rabbit, temporary separation may be appropriate if the companion is causing stress or attempting to nurse from the affected doe, though social isolation should be minimized when possible.

Quality of life assessment guides management decisions for does with galactostasis. Signs of adequate quality of life include maintained interest in food, normal or near-normal activity levels, willingness to interact with caregivers, and observable comfort much of the time. Signs of compromised quality of life include persistent appetite loss, immobility, constant hunched posture, continuous teeth grinding, and failure to respond to comfort measures. Most does with uncomplicated galactostasis maintain reasonable quality of life with appropriate pain management and supportive care, showing gradual improvement over days. Does with severe mastitis may have significantly compromised quality of life during the acute phase, requiring intensive care and honest assessment of prognosis.

Monitoring and ongoing care following a galactostasis episode prepares for potential future occurrences and supports overall health. Does should have their mammary glands checked periodically even when not breeding or lactating, as pseudopregnancy can occur spontaneously. Records should document the circumstances of the galactostasis episode, treatment provided, and outcome, creating a reference for future management. Regular veterinary check-ups allow professional assessment and guidance on breeding decisions. For does with recurrent galactostasis or those not intended for future breeding, spaying may be recommended to eliminate reproductive hormone cycling and associated mammary tissue changes.

Caregiver support and resources help owners manage does with reproductive conditions. Rabbit-specific information from organizations such as the House Rabbit Society provides guidance on general care and finding rabbit-savvy veterinarians. Online communities and local rabbit clubs offer opportunities to connect with experienced breeders who can share practical advice. Owners should feel comfortable asking their veterinarian questions and should not hesitate to seek a second opinion if uncertain about recommended treatments. The emotional and financial aspects of caring for an ill rabbit can be stressful, and caregivers should attend to their own wellbeing while providing care for their animals. Having a financial plan for unexpected veterinary expenses reduces stress when treatment is needed.

While galactostasis can affect any doe who is lactating or pseudopregnant, certain factors associated with breed characteristics may influence risk. Heavy milk-producing breeds and lines carry somewhat increased risk simply because they have more milk to accumulate if nursing is disrupted. Breeds commonly used for commercial meat production, which have been selected for large litters and robust lactation, may produce more milk than pet breeds. Conversely, some pet breeds with smaller average litters may have milk production more closely matched to typical nursing demand. Giant breeds including Flemish Giants and Continental Giants often have large litters with high milk demands, and sudden changes in litter size can result in significant engorgement.

Breed-related factors affecting litter survival indirectly influence galactostasis risk by affecting the likelihood of kit loss. Dwarf breeds carrying the lethal dwarf gene produce predictable percentages of non-viable kits when bred to each other, potentially leaving does with fuller mammary glands than their surviving kits need. Breeds prone to difficult deliveries may have higher rates of stillbirth or neonatal death. Rex breeds, particularly Mini Rex, have delicate kits that may be more vulnerable to environmental stressors in the nesting box. Breeds with heavy coats may have more difficulty keeping kits warm or may have problems with kits becoming entangled in fur. Understanding breed-specific reproductive characteristics helps breeders anticipate and manage risks.

Screening and management recommendations for breeding does include assessment of mammary gland health as part of pre-breeding evaluation. Does with history of galactostasis or mastitis should have mammary examination before breeding to assess gland condition. First-time mothers should be monitored especially closely during lactation and weaning. Breeders should maintain records of lactation success and any mammary problems across their breeding animals, using this information to make informed breeding decisions. Does who experience recurrent galactostasis despite appropriate management may not be good candidates for continued breeding. For pet does not intended for breeding, spaying prevents pseudopregnancy-associated galactostasis and provides numerous other health benefits including elimination of uterine cancer risk.

The most important related condition to galactostasis is mastitis, which represents progression from simple milk retention to bacterial infection of the mammary glands. Mastitis develops when bacteria, commonly Staphylococcus aureus, Pasteurella multocida, or various Streptococcus species, colonize the stagnant milk within engorged glands. The warm, nutrient-rich milk provides an ideal growth medium for bacteria. Mastitis is characterized by more severe systemic signs including fever, marked lethargy, and complete appetite loss, along with local signs including severely painful, hot, red mammary tissue that may progress to abscessation or tissue necrosis. Gastrointestinal stasis commonly occurs secondary to both galactostasis and mastitis, as the pain and illness cause reduced food intake, and the resulting gut slowdown creates additional serious health risks.

Conditions with similar presentations to galactostasis must be considered in the diagnostic process. Mammary tumors, while less common in rabbits than uterine tumors, can cause mammary enlargement and must be distinguished from engorgement. Pseudopregnancy with associated mammary development but without significant milk production may appear similar to early galactostasis. Abscesses in the mammary region from bite wounds, injections, or other trauma can mimic localized mastitis. Non-mammary abdominal masses, including uterine tumors or bladder stones, might be confused with mammary enlargement by inexperienced examiners. Careful physical examination and appropriate diagnostic testing distinguish these conditions.

Potential complications of galactostasis beyond mastitis include systemic effects of untreated infection and secondary conditions triggered by illness. Septicemia can develop if bacteria from infected mammary tissue enter the bloodstream, causing life-threatening systemic infection. Hepatic lipidosis develops when does stop eating and their bodies mobilize fat faster than the liver can process it. Permanent mammary gland damage including scarring and reduced function may follow severe mastitis, affecting future lactation capacity. Death can result from untreated septic mastitis. Prevention of these serious complications requires prompt recognition of galactostasis and appropriate treatment before progression occurs.
