What is hypoglycemia in dogs?
Hypoglycemia in dogs (canine hypoglycemia) is a condition which occurs when their blood sugar falls to dangerously low levels. When blood glucose level is less than 70mg/dL, your dog has hypoglycemia. However, symptoms may not start to show until their blood sugar is less than 50mg/dL. Hypoglycemia is serious, and needs to be treated right away. If you suspect that your dog has hypoglycemia, it is advisable you take them to an animal hospital for treatment before it turns out to be life threatening. Low blood sugar is often associated with diabetes and insulin overdose. However, hypoglycemia can also occur in non-diabetic dogs. Hypoglycemia is not a disease, but it is a symptom of another underlying medical problem, such as diabetes, cancer, or inflammation of the liver.
Signs and symptoms
Symptoms of hypoglycemia worsen when left untreated. It is important for dog owners to be able to identify the signs and symptoms of hypoglycemia in dogs. This will help them to take their dog for a quick diagnosis and treatment that could save their life. The initial symptoms are usually a delayed response time and low energy.
- Weakness
- Lethargy
- Trembling
- Increased thirst
- Unusual behavior
- Loss of appetite
If your dog exhibits these symptoms, you can have their blood sugar checked to determine if it is as a result of hypoglycemia.
Causes of canine hypoglycemia
There are many causes of canine hypoglycemia. However, the most common causes of hypoglycemia in dogs is insulin overdose. Dogs with diabetes do not naturally make insulin. So, they require insulin therapy to help them control their blood sugar levels. If a dog owner accidentally gives their dog too much insulin, it may result in hypoglycemia.
Other causes of canine hypoglycemia include the following:
- Toxicity;
- Abnormal growth of pancreatic cells;
- Too much exercise;
- Reduced glucose intake as a result of malnutrition;
- Portosystemic shunt.
Treatment
Initial treatment of hypoglycemia in dogs involves increasing the blood glucose levels, so as to help the dog regain its consciousness. The dog owner can apply corn syrup or glucose under the tongue or rub it on the gums. In severe cases of canine hypoglycemia, intravenous fluid infusion will be needed. Dogs with hypoglycemia will be monitored at a hospital.
Doctor’s Recommendation
While technically not qualified to comment on animals, Dogs are primarily carnivores with metabolic omnivore adaptations. One notable difference between dogs and cats is that dogs are quite good at fat metabolism and use ketones for energy. The best way to avoid hypoglycemia in a dog would be to feed the dog mainly unprocessed meat and or a ketogenic diet that is high in fat. In principle, this should be easier than in humans as pet dogs, in theory, have no autonomy over what goes in their gaster daily (though surreptitious acquisitions of contraband foodstuff are not impossible if not careful!). A carnivore-ketogenic diet would prevent hypoglycemic episodes because, theoretically, it would be possible to give the same dose of Insulin every day as there would not be an inter-day variation of glucose consumption.
