glucagonomas

Glucagonomas are rare tumors that develop in the pancreas, specifically in cells that produce the hormone glucagon. Glucagon helps regulate blood sugar levels by raising them when they are too low. When a glucagonoma forms, it often produces excess glucagon, leading to symptoms like high blood sugar, weight loss, anemia, skin rash, and digestive issues. These tumors may spread to other parts of the body if not treated. Diagnosis involves blood tests and imaging scans, and treatment typically includes surgical removal, medications to control symptoms, and addressing any spread of the tumor.
