Pancreatitis is inflammation of the pancreas , an organ in your belly that makes the hormones insulin and glucagon. These two hormones control how your body uses the sugar found in the food you eat. Your pancreas also makes other hormones and enzymes that help you break down food.
Usually the digestive enzymes stay in one part of the pancreas. But if these enzymes leak into other parts of the pancreas, they can irritate it and cause pain and swelling. This may happen suddenly or over many years. Over time, it can damage and scar the pancreas.
Most cases are caused by gallstones or alcohol abuse. The disease can also be caused by an injury, an infection, or certain medicines.
Long-term, or chronic, pancreatitis may occur after one attack. But it can also happen over many years. In Western countries, alcohol abuse is the most common cause of chronic cases.
In some cases doctors don't know what caused the disease.
The main symptom of pancreatitis is medium to severe pain in the upper belly. Pain may also spread to your back.
Some people have other symptoms too, such as nausea, vomiting, a fever, and sweating.
Your doctor will do a physical exam and ask you questions about your symptoms and past health. You may also have blood tests to see if your levels of certain enzymes are higher than normal. This can mean that you have pancreatitis.
Your doctor may also want you to have a complete blood count (CBC), a liver test, or a stool test.
Other tests include an MRI, a CT scan, or an ultrasound of your belly (abdominal ultrasound) to look for gallstones.
A test called endoscopic retrograde cholangiopancreatogram, or ERCP, may help your doctor see if you have chronic pancreatitis. During this test, the doctor can also remove gallstones that are stuck in the bile duct.
Most attacks of pancreatitis need treatment in the hospital. Your doctor will give you pain medicine and fluids through a vein (IV) until the pain and swelling go away.
