In people with diabetes, the outlook is excellent if they follow their prescribed insulin dosage, recommended diet and exercise guidelines.
Most patients with insulinomas can have them removed successfully by surgery. However, in about 15% of these patients, the insulinoma is cancerous and has spread, so it cannot be removed completely. These patients may still suffer from hypoglycemia after surgery.
Most patients with other forms of hypoglycemia can be treated successfully with changes in diet.
