Refeeding syndrome is known to occur in humans, cats, dogs, horses and cattle–and probably other species as well. Refeeding syndrome symptoms may occur when a person receives a large intake of carbohydrates following a period of starvation. When rebuilding a cat’s healthy diet, the most critical electrolytes with refeeding syndrome are phosphorus, potassium, and magnesium. A cat's resting energy requirements (RER) can be calculated by using a standard formulation: Palesty JA & Dudrick SJ (2011) Cachexia, malnutrition, the refeeding syndrome, and lessons from Goldilocks. The functional reserve of most organ systems is also reduced. OBJECTIVE To describe the clinical presentation and biochemical abnormalities occurring during the successful treatment of refeeding syndrome in a cat. The cat had clinical signs of severe starvation. Treatment is based on nutritional replacement strategies. while closely monitoring the blood glucose, potassium, phosphorous and magnesium levels. #4: This is known as the “refeeding syndrome” . Feeding severely malnourished cats can sometimes result in a condition called 'refeeding syndrome,' which can cause an insulin surge and imbalances in several electrolytes (potassium, phosphorus, magnesium). Cases in cats have been recorded secondary to hepatic lipidosis and following gastrointestinal disease in older cats such as is seen with inflammatory bowel disease, Giardia spp and lymphoma. Your veterinarian will develop a long-term plan for returning the animal to normal weight and health. Seek assistance from Objective: To describe complications associated with the management of prolonged food deprivation and hypothermia in a cat. =^_^=, Cats on Broadway Veterinary Hospital In addition to electrolyte abnormalities, another potential problem is fluid overload. Refeeding syndromes in cats can also include hypokalemia, hypomagnesemia, vitamin deficiency, fluid intolerance and glucose intolerance[4].

Calculate the resting energy requirements (and give the exponential RER formula), then feed 25% of RER the first day, increase to 50% on the 3rd day, 75% on the 5th day, and 100% on the 7th day. Case summary: A 5‐year old, spayed female domestic shorthair cat presented, after being missing for 7 weeks, showing signs of prolonged starvation and marked hypothermia. Unfortunately, certain early signs of refeeding syndrome may go undetected as they are somewhat unspecific.

Common complications developed during refeeding (eg, … After that, your vet will allow you to decrease the amount of daily feedings and increase the amount of food at each meal. Rather, the composition of macronutrients, in particular avoiding a high proportion of calories from carbohydrates, appears to be more important than the absolute number of calories[6]. Mentioning: 11 - Refeeding syndrome is characterized by severe hypophosphatemia occurring in patients given enteral or parenteral nutrition after severe weight loss. Interesting Videos It is believed that refeeding syndrome is a consequence of the cat's inability to rapidly adapt from a chronically catabolic state to an anabolic state. Last month, we discussed the fatty liver and mentioned that, for some cats, food needs to be introduced slowly, or they could have worsening electrolyte abnormalities. Refeeding leads to a surge of insulin, which may result in severe electrolyte shifts including hypokalaemia, hypomagnesaemia and hypophosphataemia. Metabolism slows down, which decreases the amount of energy needed to run the body’s basic needs. Classically, refeeding syndrome is characterised by the development of severe hypophosphatemia following the introduction of enteral or parenteral nutrition. Signs of low phosphorus (hypophosphatemia) are often related to decreased energy stores (low ATP) and may include muscle weakness, anorexia, difficulty swallowing, respiratory failure, and decreased heart function. Case report of hypoglycemia associated with refeeding syndrome in a cat - hypoglycemia is a complication common in people; not previously reported in a cat Overview on refeeding syndrome (RFS) - occurs after food is reintroduced after a period of starvation or fasting Refeeding syndromes in cats can also include hypokalemia , hypomagnesemia, vitamin deficiency, fluid intolerance and glucose intolerance [4] .

During starvation, intracellular electrolytes become depleted from fat and protein catabolism. Hypoglycemia and electrolyte deficiencies were managed with intravenous supplementation. About. This report describes a case of a domestic shorthair cat diagnosed with hepatic lipidosis following a 4-week history of decreased appetite and weight loss and in whom refeeding syndrome was documented after initiation of enteral nutrition. This change in energy source causes many electrolytes to leave cells and enter the bloodstream. When nutrition is reintroduced to these animals, either via oral, enteral or parenteral feeding, they can exhibit fluid and electrolyte shifts that are characterized as refeeding syndrome. Start weight three weeks ago was probably 4.5kg BCS 3.5/5. Dentistry What can I do for my cat - I think she has refeeding syndrome? This condition is called “refeeding syndrome.” It is a condition that can affect severely malnourished, underweight or starved animals once refeeding is started and can be life-threatening. Refeeding stimulates the release of insulin, which causes these electrolytes to quickly move back into the cells and can quickly cause a dangerous drop in blood levels, within 24 – 72 hours of starting food.

Interesting Cases These slowed bodily functions help maintain life but are usually not severe enough to cause organ failure in the short-term. Phosphorus depletion leads to a reduction in erythrocyte ATP concentration, failure of actin and myosin, altered erythrocyte membrane lipids and consequently, hemolytic anaemia. Cachexia must be treated cautiously to avoid overfeeding syndrome, which may result in serious or dangerous complications or death[1]. This report describes a case of a domestic shorthair cat diagnosed with hepatic lipidosis following a 4-week history of decreased appetite and weight loss and in whom refeeding syndrome was documented after initiation of enteral nutrition.
