Insulinoma is a pancreatic B-cell tumor and it usually causes hypoglycemia. 90% of these tumors
are single and benign.
Some other symptoms include blurred vision, headache, feelings of detachment, slurred speech, and weakness. Symptoms tend to occur in the early morning or late afternoon or after fasting or exercise.
Diagnosis is made by finding an inappropriately high serum insulin level when glucose is low.
CT scan, ultrasound, and arteriography may also be useful in detecting the tumor.
Insulinoma is managed by surgery, diet, and medical therapy.
Hope this helps.
ps - Pancreas is a gland which is situated just below stomach near the duodenum. Its main role is to produce insulin which regulates (brings down) the sugar levels in blood. So roughly, Insulinoma could be considered as opposite to Diabetes type I, where there is less insulin production due to destruction of beta cells.
