Insulinoma is a small and usually non-cancerous tumour affecting the islet cells of the pancreas, which produce insulin. Insulinoma, may result in the overproduction of insulin and cause low blood sugar levels. Normally once we eat our blood sugar rises, signalling the pancreas to produce insulin. After the blood sugar level is back to normal, insulin production should stop. With insulinoma, the production of insulin continues and this can lead to dangerously low blood sugar levels or hypoglycaemia. Weight gain occurs in 20-40% of patients, as they have to eat frequently to prevent the symptoms of hypoglycaemia.
Other symptoms of insulinoma include double or blurred vision, mood swings, weakness, excessive hunger, sudden weight gain, occasionally weight loss, sweating and palpitations.
Checking blood sugar and insulin levels in the blood helps in diagnosis of insulinoma. A low blood sugar with a high insulin level confirms the diagnosis of insulinoma. Further scans including CT scan, MRI and octreotide scan can help localize the tumour. Surgical removal of the tumour is the treatment of choice for insulinoma.
