Here's some info on hypoglycemia you may need to know.
HYPOGLYCEMIA CAN CAUSE SEIZURES IN DOGS
Hypoglycemia is defined as abnormally low blood glucose (sugar) levels. The brain requires sugar for normal function, and unlike many other organs, the brain has a very limited ability to store glucose. The brain is the organ that is predominantly affected when blood glucose gets too low.
As a primary source of energy for the body, blood glucose levels are regulated by a complex interaction of hormones and bodily processes. Hypoglycemia can be caused by abnormal function of the hormones that regulate blood sugar or by the inability of the body to store adequate amounts of glucose. Some of the specific causes of hypoglycemia include:
Insulinoma - Insulin is produced in the pancreas and causes blood sugar levels to decrease. Insulinomas are tumors of the insulin producing cells in the pancreas that causes an increase in the production of insulin, thus lowering the blood sugar levels. If an insulinoma is suspected, the insulin concentration in the blood can be measured. Surgery is usually recommended.
Insulin overdose - An excess of insulin can also occur in diabetic animals on insulin injections if the dose is inappropriate.
Reduced glucose intake - Puppies, especially toy breed puppies, are predisposed to developing hypoglycemia because they have less ability to store and mobilize glucose, compared to older animals. Puppies need frequent meals to prevent a hypoglycemic crisis.
Hypoandrenocorticism (Addison's Disease) - Hypoandrenocorticism results from a deficiency in the secretion of hormones from the adrenal glands. The cause of Hypoandrenocorticism is unknown, although immune-mediated destruction of the adrenal gland is suspected in most cases.
The signs and symptoms of hypoglycemia are similar regardless of the cause. These include lethargy, weakness, incoordination, seizures, nervousness, tremors and hunger. In severe cases the dog may become unconscious.
A diagnosis of hypoglycemia as a cause of neurological problems is based on the presentation of clinical signs of hypoglycemia, blood glucose concentration test shows levels below normal, and the fact that clinical signs go away when glucose is administered to the patient.
If the neurological signs are proven to be due to hypoglycemia, the cause of the hypoglycemia must be found. In addition to a medical history and examination, laboratory tests are usually performed. Emergency treatment of hypoglycemia involves administration of glucose usually by intravenous injection. Giving a quickly absorbed source of sugar (syrup, honey, or jam) by mouth may also be effective.
