Insulinoma
What is it?
An insulinoma is a tumor of the pancreas that produces too much insulin, causing low blood sugar. It typically affects ferrets three to five years old.
What signs should I watch for?
Signs to watch for include lethargy, sleeping more, hard to wake; staring into space; pawing at the mouth, drooling; weakness in the hind legs; and seizures or collapse (EMERGENCY).
How is it diagnosed and treated?
A fasting blood sugar test is the main diagnostic step. Treatment includes frequent high-protein meals, medication to raise blood sugar, and sometimes surgery to remove nodules.
Can it be prevented, and what's the outlook?
- Insulinoma is usually not curable, but many ferrets live comfortably for a year or more with management.
- Avoid sugary treats.
