The most common cause of pancreatitis is excessive alcohol consumption. Other possible causes include gallstones, certain medications, some medical conditions, and injury to the pancreas. Alcohol Consumption
Excessive alcohol consumption is the most common cause of pancreatitis. Alcohol is toxic to the pancreas, and even moderate levels of drinking can lead to inflammation and pancreatitis. Heavy drinking affects the pancreas in two ways: it increases the production of digestive enzymes, and it disrupts the normal balance of the pancreas. This can lead to inflammation, and in some cases, permanent damage.
Gallstones
Gallstones can block the pancreas' ducts and cause pancreatitis. The blockage causes the digestive enzymes to become trapped in the pancreas, which can cause inflammation. Gallstones are made up of cholesterol and other substances, and they can form when the gallbladder doesn't empty properly.
Certain Medications
Certain medications, such as steroids, certain antibiotics, and some cancer drugs, can cause pancreatitis. These medications can cause inflammation and damage to the pancreas.
Medical Conditions
Some medical conditions, such as cystic fibrosis and HIV/AIDS, can also lead to pancreatitis. These conditions can affect the pancreas' ability to produce enzymes, and can cause inflammation.
Injury to the Pancreas
Injuries to the pancreas, such as a vehicle accident or a fall, can cause pancreatitis. The blunt force can cause inflammation and damage to the pancreas.
