What are the symptoms of insulinoma?

Symptoms of insulinoma may include dizziness, disorientation and weight gain — often patients feel better after they eat, and so eat more frequently. Eighty-five percent of patients have blurred vision, palpitations, sweating and weakness, as hypoglycaemia produces adrenaline which causes these effects. Seizures are not uncommon.

The lack of food to the brain results in the signs seen which usually are periodic (they come and go on their own). The early signs are: depression, lethargy, blankly staring with poor response to sound or touch, salivating and pawing at the mouth (because they are nauseated), and periodic weakness, especially of the hind quarters. Sometimes enlarged spleens are seen. More severe signs are stupors, seizures, severe weakness, and coma.
