Insulinoma
Symptoms and Signs of Insulinoma
 Hypoglycemia secondary to an insulinoma occurs during fasting. Symptoms of hypoglycemia due to insulinoma are insidious and may mimic various psychiatric and neurologic disorders. Central nervous system disturbances include headache, confusion, visual disturbances, motor weakness, palsy, ataxia, marked personality changes, and possible progression to loss of consciousness, seizures, and coma. Symptoms of sympathetic stimulation (faintness, weakness, tremulousness, palpitation, sweating, hunger, and nervousness) are often present.
