The pancreas is a large gland that is located beneath the stomach and next to the small intestine. The pancreas has two main functions: It aids digestion by releasing powerful digestive enzymes into the small intestine. Insulin and glucagon are released into the bloodstream. These hormones aid in the body's ability to regulate how it uses food for energy. When digestive enzymes start acting before the pancreas releases them, the pancreas can be harmed. Acute pancreatitis, chronic pancreatitis, hereditary pancreatitis, and pancreatic cancer are all conditions that affect the pancreas. Because the pancreas is inaccessible, diagnosing pancreatic disorders can be difficult. The pancreas can be assessed using a variety of approaches.
