What are the clinical signs of hyperthyroidism in cats
PUPD, increased appetite, weight loss, vocalization, vomiting, diarrhea
Why is insulin secreted by the pancreas
In response to increasing glucose levels
What does insulin do
It allows the cells to use glucose. Even though the blood glucose is high the cells cannot use the glucose so they break down fat and use protein from the lean body mass
What is special about insulin
It is the only hormone to lower blood glucose. Causes blood glucose uptake by cells
Which hormones cause blood glucose to rise
Glucagon, Adrenaline, cortisol, growth hormone
What is type one diabetes
Insulin-dependent diabetes more common in dogs. Pancreas is not producing enough insulin usually because of immune destruction of the beta cells of the pancreas

Which diabetes is associated with obesity
Type two. Fat cells hide receptors for insulin
What are the predisposing factors for diabetes
Obesity, middle age, genetics, other hormones. Elevated levels of Cortizone, progesterone can cause insulin resistance
Describe carbohydrate metabolism in cats

Stabilize glucose levels without causing hypoglycemia. Minimize hyperglycemia, provide optimal amount of nutrients, minimize clinical signs, avoid hypoglycemia
What is the blood glucose concentration normally for dogs
5-10 to 12 mmol/l
What is the blood glucose concentration normally for cats
5-14-16 mmol/l
What is the renal threshold
14 mmol per liter
What is the normal blood glucose range in non-diabetic cats
2.6 to 8.4 mmol per liter
What is the goal of an ideal blood glucose curve
To produce a blood glucose curve that approaches the reference range but avoids potentially fatal hypoglycemia for example 5 to 14mmol for most of each 24 hour period.
What is the three important dietary treatments for diabetes
Be consistent with amounts, consistent time in consistent ingredients consistent proportion of carbohydrates fat and protein. Slow absorption of glucose from the intestine by having a food low in simple sugars high in complex carbohydrates such as barley to slow glucose absorption. Add fiber to slow gastrointestinal transit time.
What should a diabetic diet have
Good quality and quantity of protein to protect lean body mass will also provide amino acids for gluconeogenesis. Antioxidants such as vitamin E, fat content will depend on body score: obese versus skinny diabetics
What nutraceutical should a diabetic diet contain
Chromium to use insulin better, Carnithine to help with fat metabolism, antioxidants
How do you reduce glucose elevations in cats
Reduce carbohydrate and increase protein to result in slower glucose elevations
What are some common causes of critical illness
Trauma, neoplasia, anemia, organ failure, sepsis, central nervous system disease, toxins, immune mediated diseases
How is starvation different in the sick animal
A sick animal up regulates its metabolism in spite of starvation
What happens when a healthy animal is in starvation
It down regulates its metabolism in the face of starvation because he wants to conserve energy
What happens to the G.I. tract during starvation
The intestinal villi get nutrition directly from intestinal contents. If there’s no food in the G.I. tract you get Villas atrophy where you cannot digest and absorb food, greater chance of bacterial translocation. Also due to starvation the stomach shrinks.
What happens in starvation
The body uses that stores for energy. Sacketts metabolized into key tones which may be used as an energy source in some tissues. As there’s no storage form of protein in the body muscle proteins are cannibalized into energy. This results in the loss of lean body mass. There’s a rapid loss of lean body mass in the anorexic sick animal.
What does a sick Animal need
Increased protein
What diet does an anorexic sick Animal need
High-quality protein and high energy (fat)
How do you administer nutritional support to an animal
Force-feeding, tube feeding such as the nasogastric tube, esophageal tube, pharyngostomy tube, gastric tube, jejunal tube
What are the advantages of tube feeding
Less stressful for the animal. Can meet the daily caloric needs. Can easily give small of those often which will be easier for the animals digestive system to handle
What are the benefits of nutritional support
Decreased morbidity. improved tolerance to invasive procedures, shorter hospitalizations. decreased incidence of infection, rapid wound healing, fewer complications.
What food can you put in a feeding tube
A/d, recovery. Mix one to one with water
How many calories are liquid diets
1 cal per milliliter approx. 0.6 for a/d
What are the diet characteristics for a critical care diet
High-fat, high biological value protein, low carbohydrate. Increased branched-chain amino acid’s, glutamine to feed small intestine, arginine to metabolize ammonia, B vitamins, Add zinc.
What is the function of the liver
Metabolism of fats carbs and protein, glucose that is stored there, produces albumin, detoxification for the ammonia cycle, bile metabolism, makes coagulation factors
What is idiopathic hepatic lipidosis
Occurs when cat stops eating or is that the negative calorie state for period of time. Approximately two weeks of eating 1/2-3/4 of the normal portion. Obese cats are more predisposed. Protein malnutrition develops very fast when cats do not eat
What are the clinical signs of fatty liver disease
History of anorexia, weight loss, lethargy, vomited, jaundice, diarrhea
How long do do you Normally place a feeding tube
6-8weeks or until eating on his own
How do you avoid refeeding syndrome
Feed small amounts for the first few days even though caloric requirements aren’t being met
What is the minimum daily recommended calories for a cat
60kcal/kg/day
What are the dietary goals for liver disease
Reduce livers workload by provided adequate daily energy intake. Moderate level of fat and highly digestible carbohydratesAvoid hyperammonemia. Feed high-quality protein. Feed small amounts often to avoid getting undigested protein in the large bowel.
Why do you want branched chain amino acids
They get used up faster for gluconeogenesis
Why do you include arginine in the liver disease diet
Because it is involved in the urea cycle
Why do you include Taurine in cats
Because it is an essential amino acid
What are common heart problems
Congestive heart failure, mitral valve insufficiency, cardiomyopathy, arrhythmia
How does the body compensate in heart failure
The heart pumps less so the body thinks it needs more blood volume. Increased blood pressure plus more work for the heart
What is a drug that can treat heart failure
Lasix, diuretics, fortekor, vetmedin
What are the dietary considerations for heart disease
L-Carnithine, restricting sodium, add Taurine, omega-3 fatty acid EPA’s DHA.
