Insulinoma is one of the most common diseases of ferrets. It is a tumor of the insulin-producing islet cells in the pancreas. Insulin is the hormone responsible for regulating blood sugar levels and getting sugar into the body's cells where it is used for energy. When too much insulin is produced by this tumor, the animal has a low blood sugar (hypoglycemia). You should avoid sugary foods for ferrets in general, but especially for those with this type of tumor, as it will result in more insulin production and can worsen the symptoms. Hypoglycemia results in the common symptoms of weight loss, excess salivation or drooling, depression or lethargy, and, in extreme cases, seizures. Treatment options include surgery, medication to control symptoms, and nutritional management. No single treatment works for all individuals, so it is important to work with your veterinarian to develop a plan for managing or treating this disease in your ferret.
