Eclampsia / Hypocalcemia (postpartum)

Eclampsia, also known as postpartum hypocalcemia or milk fever, is a serious and potentially life-threatening metabolic emergency that occurs in nursing guinea pig sows when blood calcium levels drop to dangerously low levels. This condition typically develops within the first few weeks after giving birth, when the demands of milk production rapidly deplete the mother's calcium reserves faster than they can be replenished through diet. Eclampsia represents one of the most urgent reproductive emergencies in guinea pig medicine and requires immediate veterinary intervention to prevent fatal outcomes.

Eclampsia occurs with concerning frequency in nursing guinea pigs, particularly in sows nursing large litters of four or more pups, first-time mothers, and those with inadequate nutritional support during pregnancy and lactation. The condition develops because guinea pigs cannot mobilize calcium from their bones quickly enough to meet the intense demands of milk production. Unlike some other species, guinea pigs have limited ability to regulate calcium homeostasis under stress, making them particularly vulnerable to this metabolic crisis. The rapid onset and progression of symptoms means that affected sows can deteriorate from apparently healthy to critically ill within hours.

The impact of eclampsia on the nursing sow is severe and affects multiple body systems. Calcium is essential for proper muscle and nerve function throughout the body. When blood calcium levels fall below critical thresholds, the sow experiences progressive neurological and muscular dysfunction that can include tremors, weakness, seizures, and eventually cardiac arrest. Without treatment, eclampsia is almost universally fatal. The pups are also at risk, as a severely affected mother cannot nurse effectively, and pups may be injured if the mother experiences seizures or becomes unable to care for them appropriately.

The good news is that eclampsia is treatable when recognized early and addressed promptly by a veterinarian experienced with guinea pig medicine. Emergency calcium supplementation can rapidly reverse the acute symptoms and stabilize the sow. However, the key to successful outcomes lies in recognizing the early warning signs before the condition progresses to seizures and collapse. Guinea pig owners with nursing sows should be educated about the signs of eclampsia and prepared to seek emergency care at the first indication of problems. Prevention through proper nutrition during pregnancy and lactation is also highly effective at reducing the incidence of this dangerous condition.

The primary cause of eclampsia is an imbalance between the calcium demands of milk production and the calcium available in the mother's bloodstream and diet. Milk production requires substantial amounts of calcium, as guinea pig milk contains high levels of this mineral to support the rapid growth and bone development of the pups. When a sow begins nursing, her calcium requirements may double or triple compared to her non-pregnant baseline. If dietary calcium intake is insufficient to meet this demand, and the body cannot mobilize bone calcium quickly enough, blood calcium levels fall progressively until reaching dangerous levels that impair muscle and nerve function.

Genetic and physiological factors influence individual susceptibility to eclampsia. Guinea pigs have relatively inefficient mechanisms for rapidly mobilizing calcium from bone stores compared to some other species. The parathyroid glands and vitamin D metabolism, which regulate calcium balance, may not respond quickly enough to the acute demands of lactation. Individual variation in calcium absorption efficiency, bone calcium reserves, and hormonal responsiveness means that some sows are more vulnerable than others even under similar nutritional conditions. First-time mothers may be at higher risk because their bodies have not previously adapted to the demands of lactation.

Environmental and nutritional factors play a crucial role in eclampsia development. Inadequate calcium in the diet during late pregnancy and lactation is a primary risk factor. Diets that are too high in phosphorus relative to calcium can interfere with calcium absorption and metabolism. Inadequate vitamin C intake impairs calcium metabolism and overall metabolic function in guinea pigs. Poor quality hay or vegetables with low calcium content may not provide sufficient mineral nutrition. Stress from environmental factors, overcrowding, or inappropriate housing can increase metabolic demands and impair feeding behavior, worsening nutritional deficiencies.

Several specific risk factors have been identified for eclampsia in nursing guinea pigs. Sows nursing large litters of four or more pups face dramatically higher calcium demands than those with smaller litters. Young, first-time mothers may have smaller calcium reserves and less metabolic adaptation to lactation demands. Older sows or those in poor body condition may have depleted calcium stores. Sows who experienced difficult pregnancies, pregnancy toxemia, or other health issues may be metabolically compromised entering lactation. Feeding diets low in calcium or high in oxalates, which bind calcium and prevent absorption, increases risk. Concurrent illness or stress that reduces appetite further compounds the problem.

The mechanism of eclampsia development involves progressive depletion of blood calcium as lactation demands exceed intake and mobilization capacity. Normal blood calcium levels in guinea pigs range from approximately nine to twelve milligrams per deciliter. As levels drop below this range, early symptoms of hypocalcemia begin to appear. When calcium falls below approximately seven to eight milligrams per deciliter, significant neuromuscular signs develop. Calcium is essential for proper nerve signal transmission and muscle contraction, including the heart muscle. Low calcium causes muscles to become hyperirritable and prone to spasms, eventually progressing to tetany and seizures. Cardiac muscle dysfunction can cause arrhythmias and cardiac arrest. Without intervention, this cascade leads rapidly to death.

Early warning signs of eclampsia may be subtle and easily missed if owners are not vigilant. As guinea pigs are prey animals with strong instincts to hide illness, initial symptoms may be dismissed as tiredness from nursing. Early signs include decreased activity and lethargy, particularly noticeable in a normally active sow. The affected guinea pig may spend more time resting and less time eating or interacting with her pups. Mild muscle trembling or twitching may be visible, particularly when the sow is at rest or after handling. She may appear slightly uncoordinated or wobbly when walking. Reduced appetite and decreased water consumption are common early findings. Any nursing sow showing unusual tiredness or behavioral changes within the first few weeks postpartum should be evaluated promptly.

The most common recognizable symptoms of progressing eclampsia include obvious muscle tremors and weakness. The sow may have difficulty standing or maintaining her balance, appearing to stagger or weave when she attempts to walk. Muscle twitching becomes more pronounced and may be visible in the face, ears, and limbs. The sow typically becomes progressively more lethargic and may resist handling or movement. She often loses interest in food and water entirely. Nursing behavior decreases as the sow becomes too weak to position herself appropriately or allow pups to nurse. The pups may become more vocal and restless as they receive less milk, which can alert observant owners to a problem.

Behavioral changes during eclampsia progression are significant indicators of worsening condition. The affected sow may become unusually quiet and withdrawn, hiding more than normal and not responding to sounds or activity that would usually interest her. Alternatively, some sows become restless and agitated, unable to settle comfortably. She may make distressed vocalizations or appear anxious. Maternal behavior toward the pups often deteriorates, with the sow ignoring or even avoiding her offspring. Some sows may become uncharacteristically irritable or defensive. Changes in urination and defecation patterns may occur, with reduced output reflecting decreased food and water intake.

Physical signs of eclampsia become increasingly obvious as the condition progresses. The sow's body may feel unusually tense due to muscle rigidity. Her breathing may become rapid and labored as respiratory muscles are affected. Body temperature may be slightly elevated due to muscle activity or may drop if the sow is progressing toward shock. The eyes may appear somewhat glazed or unfocused. The mouth may be held slightly open, and there may be excessive salivation. The coat may appear rough or unkempt as grooming behavior decreases. Weight loss from reduced eating may be noticeable if the condition has been progressing over several days.

Symptom progression in untreated eclampsia follows a dangerous and often rapid course. Initial tremors and weakness give way to severe muscle rigidity and tetany, where muscles become locked in contraction. The sow may lie on her side, unable to rise, with legs extended stiffly. Seizures may occur, characterized by convulsive movements, paddling of the legs, and loss of consciousness. Between seizures, the sow may be unresponsive or minimally responsive. Breathing becomes increasingly labored as respiratory muscles are affected. Without treatment, cardiac arrhythmias develop due to the effects of low calcium on heart muscle, eventually leading to cardiac arrest and death. The progression from early symptoms to life-threatening crisis can occur over just a few hours.

Emergency symptoms requiring immediate veterinary care include any seizure activity, severe muscle rigidity or tetany, inability to stand or walk, collapse, unconsciousness or minimal responsiveness, labored or irregular breathing, and pale or blue-tinged gums indicating poor circulation. These signs indicate that the sow is in immediate life-threatening danger and requires emergency calcium supplementation without delay. Owners should not wait to see if symptoms improve on their own, as deterioration can be rapid and fatal. Transportation to a veterinary clinic should be done carefully, keeping the sow warm and protected from injury during any seizure activity.

Initial examination by an exotic veterinarian or veterinarian experienced with guinea pig medicine is essential for diagnosing eclampsia. The veterinary team will first assess the sow's overall condition, including heart rate and rhythm, respiratory rate, temperature, and level of consciousness. A thorough history will be taken, including the date of delivery, number of pups, any complications during birth, diet during pregnancy and lactation, and progression of symptoms. The veterinarian will evaluate muscle tone, looking for the rigidity and tremors characteristic of hypocalcemia. Neurological assessment will check for responsiveness, reflexes, and any evidence of seizure activity. The general body condition and hydration status will be assessed.

Diagnostic tests are typically performed to confirm hypocalcemia and assess the sow's overall metabolic status. Measurement of blood calcium levels is the definitive diagnostic test for eclampsia. Both total calcium and ionized calcium may be measured, with ionized calcium being the physiologically active form. Blood glucose levels are important to assess, as hypoglycemia often accompanies eclampsia and can contribute to symptoms. A complete blood chemistry panel helps evaluate kidney function, which affects calcium regulation, and identifies other metabolic abnormalities. Complete blood count may reveal signs of infection or other concurrent illness. In some cases, additional tests such as parathyroid hormone levels may be considered to rule out other causes of hypocalcemia.

Differential diagnosis is important to distinguish eclampsia from other conditions with similar presentations. Pregnancy toxemia, a metabolic disorder of late pregnancy, can cause similar symptoms and may occur close to the time of delivery. Hypoglycemia alone can cause weakness, tremors, and seizures. Other causes of seizures in guinea pigs include infectious diseases, toxin exposure, and neurological conditions. Metritis or other postpartum infections can cause lethargy and weakness. Mastitis may affect nursing sows and cause behavioral changes. Traumatic injuries from difficult delivery could cause neurological signs. The clinical history, timing of symptoms relative to delivery, and blood calcium levels help distinguish eclampsia from these other conditions.

Confirmation of eclampsia and severity assessment combines the clinical presentation with laboratory findings. A blood calcium level below the normal range in a nursing sow with compatible clinical signs confirms the diagnosis. The degree of hypocalcemia correlates with symptom severity, with lower calcium levels generally associated with more severe clinical signs. The presence of seizures, tetany, or cardiovascular abnormalities indicates severe, life-threatening hypocalcemia requiring aggressive treatment. Assessment of concurrent conditions such as hypoglycemia, dehydration, or infection guides comprehensive treatment planning. The sow's response to initial calcium supplementation provides both diagnostic and prognostic information, as true eclampsia typically shows rapid improvement with calcium therapy.

Emergency and immediate treatment of eclampsia focuses on rapid restoration of blood calcium levels to stop life-threatening symptoms. Upon arrival at the veterinary clinic or during emergency care, the sow will be handled gently to minimize stress and prevent triggering seizures. Intravenous calcium gluconate is the treatment of choice for severe eclampsia, administered slowly while monitoring heart rate and rhythm, as rapid calcium administration can cause dangerous cardiac effects. The dose is carefully calculated based on the sow's body weight and severity of symptoms. During calcium administration, the sow may show visible improvement as muscle tremors decrease and rigidity resolves. If intravenous access is not immediately available, subcutaneous calcium gluconate can be administered as an alternative.

Medical management following initial stabilization includes continued calcium supplementation and supportive care. After the emergency intravenous dose, additional calcium may be given subcutaneously to maintain adequate blood levels. Oral calcium supplementation is started as soon as the sow is able to eat. Vitamin D supplementation may be added to improve calcium absorption and utilization. If hypoglycemia is present, dextrose supplementation is provided. Fluid therapy addresses dehydration from reduced water intake. If the sow has been unable to eat, her gut function may be compromised, requiring careful nutritional support to prevent GI stasis. Body temperature is maintained with supplemental warming if the sow is hypothermic.

Management of nursing and pups is an important component of treatment. In severe cases, the pups may need to be separated from the mother temporarily to reduce lactation demands while she recovers. Pups may require supplemental feeding with a guinea pig milk replacer or fostering to another nursing sow if available. Once the mother is stable, nursing can be gradually reintroduced, often starting with shorter nursing periods and supplemental feeding for the pups. If the litter is large, consideration may be given to fostering some pups to reduce the mother's calcium demands. In some cases, the decision may be made to wean the pups early if the mother cannot tolerate continued nursing without recurrence of symptoms.

Supportive care during and after treatment addresses the sow's overall recovery needs. Syringe feeding with a high-quality herbivore recovery formula may be necessary initially if the sow is not eating independently. Vitamin C supplementation is essential, as requirements are elevated during stress and recovery. A quiet, warm environment reduces stress and metabolic demands. Soft, clean bedding allows comfortable rest. Easy access to food and water encourages return to normal eating and drinking behavior. Pain is generally not a major component of eclampsia once calcium levels are corrected, but overall comfort measures help recovery. Close monitoring for any recurrence of symptoms is essential in the days following treatment.

Alternative and complementary treatments play a supportive role in recovery from eclampsia. Ensuring a calm, stress-free recovery environment is important, as stress increases metabolic demands. Probiotic supplementation supports gut health, particularly if the sow's eating has been disrupted. Offering favorite foods encourages appetite and voluntary eating. High-calcium vegetables such as kale, parsley, and dandelion greens can be offered once the sow is eating normally. Some owners find that hand-feeding or staying nearby during meals provides comfort and encouragement. Companionship with familiar guinea pigs, once the sow is stable, may reduce stress, though separate housing may be needed initially.

Treatment decisions involve consideration of multiple factors. The severity of the sow's condition at presentation influences the intensity of initial treatment. The number and age of pups affects decisions about continuing versus interrupting nursing. The sow's overall health and any concurrent conditions influence prognosis and treatment approach. Owner ability to provide intensive home care and follow-up affects planning for discharge. Financial considerations may influence some decisions, though eclampsia treatment is typically straightforward compared to some other emergencies. Decisions about future breeding should be discussed, as recurrence with subsequent pregnancies is possible. With prompt, appropriate treatment, most sows with eclampsia can recover fully, though careful management of future pregnancies is recommended.

Recovery timeline following eclampsia treatment is generally rapid once blood calcium levels are restored, though the sow may need continued support during the nursing period. Many sows show dramatic improvement within minutes to hours of calcium supplementation, with tremors resolving and strength returning quickly. Complete recovery of normal activity and behavior typically occurs within twenty-four to forty-eight hours after treatment. However, the underlying metabolic stress of nursing continues until pups are weaned, so ongoing monitoring and nutritional support remain essential. Most sows can return to nursing their pups within a day or two of treatment, assuming no severe complications developed.

Post-treatment care requires careful attention to prevent recurrence. Oral calcium supplementation typically continues throughout the remainder of the nursing period. The diet should be optimized to include calcium-rich foods such as kale, parsley, and other leafy greens, while maintaining unlimited hay and appropriate vitamin C intake. Water consumption should be encouraged to support milk production. Food and water intake should be monitored daily. The sow should be weighed regularly to ensure she is maintaining or regaining body condition. If nursing is continued, the sow should be observed for any return of tremors, weakness, or other symptoms suggesting recurrence of hypocalcemia. Pup weight gain should be monitored to ensure adequate milk production.

Prognosis factors include the severity of eclampsia at diagnosis, the rapidity of treatment, and the sow's underlying health status. Sows treated early, before developing seizures or severe tetany, generally have excellent prognoses. Those with more severe symptoms may have slightly longer recovery times but usually recover fully if treatment is initiated before cardiac complications develop. Sows who experienced prolonged seizures or cardiac arrest before treatment have more guarded prognoses. The development of complications such as aspiration pneumonia from seizures, injury during convulsions, or secondary infections worsens prognosis. Concurrent conditions such as pregnancy toxemia or metritis require additional treatment and may prolong recovery.

Long-term outlook for eclampsia survivors is generally excellent with appropriate ongoing care. Most sows make full recoveries and can successfully wean their pups without further complications. Future breeding decisions should be carefully considered, as sows who have experienced eclampsia may be at increased risk with subsequent pregnancies and nursing periods. If future breeding is planned, particular attention should be paid to calcium nutrition before, during, and after pregnancy. Larger litter sizes should be avoided if possible through breeding choices or early fostering of excess pups. Some veterinarians may recommend against breeding previously affected sows, particularly if eclampsia was severe. Regular veterinary monitoring during future pregnancies and nursing periods is advisable for sows with a history of eclampsia.

Primary prevention of eclampsia centers on providing adequate calcium nutrition throughout pregnancy and lactation. The diet should include calcium-rich vegetables such as kale, parsley, cilantro, and dandelion greens offered daily. High-quality guinea pig pellets fortified with calcium and vitamin D should be provided as part of the daily diet. Unlimited grass hay provides fiber and additional minerals. Fresh, clean water must always be available, as hydration supports milk production and overall metabolic function. Calcium supplementation beyond dietary sources may be recommended by a veterinarian for sows with large litters or those considered at higher risk. The calcium-to-phosphorus ratio in the diet should be appropriate, with calcium slightly higher than phosphorus.

Environmental prevention involves maintaining optimal conditions to support the nursing sow's health and reduce metabolic stress. Housing should be appropriately sized and comfortable, allowing the sow to rest while still having easy access to food and water. Temperature should be maintained in the comfortable range for guinea pigs, as temperature extremes increase metabolic demands. Clean, dry bedding supports hygiene and comfort. A quiet, low-stress environment allows the sow to focus energy on nursing rather than stress responses. If multiple guinea pigs are housed together, compatible groupings reduce social stress. Adequate space allows the sow to rest away from the pups periodically, which is normal nursing behavior.

Dietary prevention strategies ensure optimal nutrition during the demanding lactation period. Vitamin C supplementation should be continued and possibly increased during nursing, as demands are elevated. Avoid foods high in oxalates, such as spinach, which can bind calcium and reduce absorption. Provide a variety of calcium-rich vegetables to ensure adequate intake even if the sow has individual preferences. Avoid sudden diet changes that could disrupt eating and gut function. Monitor food intake daily and intervene promptly if the sow's appetite decreases. Consider offering food more frequently to support increased nutritional demands. Fresh foods should be offered at times when the sow is likely to eat, such as morning and evening.

Health maintenance practices support uncomplicated nursing and reduce eclampsia risk. Veterinary checkup shortly after delivery allows early identification of any problems. Regular weighing of the sow tracks whether she is maintaining body condition during lactation. Monitoring the pups' weight gain indicates whether milk production is adequate. Observing nursing behavior ensures the sow is feeding pups appropriately. Regular observation for any early signs of illness, lethargy, or behavioral changes allows prompt intervention. If the sow appears stressed by a very large litter, early fostering or supplemental feeding of pups can reduce her metabolic burden.

Early intervention strategies maximize outcomes if problems begin to develop. Owners should know the signs of eclampsia and be prepared to seek veterinary care immediately if symptoms appear. Any tremors, weakness, or unusual behavior in a nursing sow should prompt immediate veterinary consultation. Emergency veterinary contact information should be readily available. Having a small animal carrier prepared allows quick transport if needed. If a sow has a history of eclampsia with previous litters, proactive veterinary management with additional calcium supplementation and early monitoring can prevent recurrence. Consideration should be given to litter size reduction through early fostering if a sow is struggling with a very large litter.

Daily management and care adjustments for a guinea pig recovering from eclampsia require ongoing attention throughout the nursing period. The recovering sow should have easy access to food and water at all times, with calcium-rich vegetables offered at least twice daily. Oral calcium supplementation as prescribed by the veterinarian should be given consistently. The sow's eating and drinking behavior should be monitored to ensure adequate intake. She should be observed multiple times daily for any signs of recurring symptoms such as tremors or weakness. If nursing is continued, the sow's comfort and nursing behavior should be watched to ensure she is caring for pups appropriately. Vitamin C supplementation continues at recommended levels.

Home environment modifications support recovery and prevent recurrence. The cage should be set up to minimize the need for climbing or excessive activity, allowing the sow to conserve energy for nursing and recovery. Food and water should be positioned conveniently near preferred resting areas. Soft, comfortable bedding encourages rest. The environment should be kept quiet and calm, away from loud noises and disturbances that increase stress. Temperature should be maintained in the comfortable range. If pups are still nursing, arrangements should allow the sow to access pups easily while also having space to rest separately when desired. Cage cleanliness should be maintained without causing excessive disruption.

Quality of life maintenance is essential during the recovery and remaining nursing period. The sow may tire more easily than usual and should be allowed to rest as needed. Handling should be kept gentle and minimal to reduce stress. Brief, positive interactions with owners can provide comfort without excessive demands. If housed with other guinea pigs, compatible companions can provide social support, but any guinea pigs that cause stress or competition should be separated. As the sow regains strength, normal activities and interactions can gradually resume. Monitoring emotional state and behavior helps identify any concerns about ongoing well-being.

Ongoing monitoring and care continue until pups are weaned and the sow has fully recovered. Daily observation for any return of eclampsia symptoms is essential, particularly during the first two weeks after treatment. The sow should be weighed regularly to track body condition. Eating, drinking, and activity levels should be monitored. Pup weight gain indicates whether milk production is adequate. Any decrease in the sow's condition, reduced eating, or return of symptoms should prompt immediate veterinary consultation. The weaning process should be gradual when possible, allowing the sow's calcium demands to decrease slowly. Post-weaning veterinary checkup confirms complete recovery.

Caregiver support and resources help owners manage the recovery period successfully. Clear written instructions from the veterinarian regarding medication administration, diet, and warning signs ensure consistent care. Keeping a daily log of observations, supplements given, and the sow's behavior helps track progress and identify any concerning trends. Connecting with guinea pig rescue organizations or online communities can provide emotional support and practical advice from others who have managed similar situations. Understanding that the intensive monitoring period is temporary and will conclude with weaning helps maintain perspective. Veterinary staff should be contacted with any questions or concerns rather than waiting to see if problems resolve on their own.

All guinea pig breeds can potentially develop eclampsia, as the condition is related to the metabolic demands of lactation rather than breed-specific genetic factors. However, certain breed characteristics and individual factors may influence risk. Larger guinea pig breeds may produce more milk, potentially increasing calcium demands. Breeds or lines that tend to have larger litters face higher risk due to greater nutritional demands of nursing multiple pups. Satin guinea pigs may have altered calcium metabolism related to their underlying osteodystrophy condition, potentially affecting their ability to meet lactation demands. Individual animals from any breed with naturally high milk production may face greater risk than lower-producing individuals.

Moderate-risk considerations apply broadly and are more related to individual circumstances than breed. First-time mothers of any breed may be at increased risk compared to experienced sows whose bodies have previously adapted to lactation demands. Younger breeding females may have smaller calcium reserves than fully mature animals. Older sows or those in poor body condition entering pregnancy may have depleted reserves. Guinea pigs with unknown breeding backgrounds from pet stores or rescues may have nutritional deficiencies from earlier inadequate care. Animals with concurrent health conditions that affect metabolism or appetite may be at elevated risk. The primary risk factors cutting across all breeds are large litter size, inadequate calcium nutrition, and first-time motherhood.

Screening recommendations for breeders focus on nutritional management and careful observation rather than genetic selection. Breeders should ensure all breeding females receive optimal nutrition before, during, and after pregnancy. Sows with previous eclampsia episodes should be carefully evaluated before rebreeding, and if bred again, should receive enhanced nutritional support and monitoring. Litter sizes should be tracked, and sows consistently producing very large litters may require additional calcium supplementation. Breeders should be educated about eclampsia signs and have protocols for rapid response if symptoms develop. Record-keeping of any reproductive complications helps identify animals or lines that may need additional management. While eclampsia is not considered hereditary, selecting for moderate rather than excessive milk production may help reduce risk.

Commonly co-occurring conditions with eclampsia reflect the metabolic stresses of late pregnancy and lactation. Pregnancy toxemia, also known as ketosis, may occur in late pregnancy and predispose sows to metabolic imbalances after delivery. Hypoglycemia, or low blood sugar, frequently accompanies eclampsia and can contribute to symptoms. Mastitis, infection of the mammary glands, may develop in nursing sows and can reduce appetite, worsening nutritional status. Metritis, infection of the uterus after delivery, causes systemic illness that compounds metabolic stress. Dehydration from reduced water intake during illness can worsen metabolic imbalances. GI stasis, a dangerous slowdown of gut function, may develop secondary to reduced eating and overall illness.

Conditions with similar presentations to eclampsia require differentiation for appropriate treatment. Pregnancy toxemia shares many symptoms including weakness, lethargy, and loss of appetite, but occurs before delivery rather than after. Hypoglycemia alone can cause tremors and weakness. Other causes of seizures in guinea pigs include infectious diseases such as meningitis, toxin exposure, and brain lesions. Electrolyte imbalances beyond calcium, such as low potassium or sodium, can cause muscle and nerve dysfunction. Severe pain from any cause can produce behavioral changes and reduced eating. Postpartum infections may cause lethargy and depression that could initially resemble early eclampsia. Blood testing helps distinguish between these various conditions.

Potential complications of eclampsia include secondary conditions resulting from the acute crisis or its treatment. Aspiration pneumonia may occur if the sow inhales food or fluid during seizures. Traumatic injuries from falling or convulsing are possible in uncontrolled cases. Pup injuries or mortality may occur if the mother seizes while nursing or is unable to care for pups during illness. Hypoglycemia may persist or recur if eating is not restored promptly. If nursing is interrupted, mastitis may develop from milk accumulation. GI stasis can develop if the sow is not eating adequately during or after treatment. Recurrence of eclampsia during the same nursing period is possible if underlying nutritional issues are not corrected. Owners should be aware of these potential issues and monitor recovered sows carefully.
