what causes pancreatitis

Pancreatitis is inflammation of the pancreas, caused by several factors. The most common causes of pancreatitis include:

  • Gallstones: These can block the bile or pancreatic ducts, causing pancreatic enzymes to back up and irritate the pancreas, leading to inflammation.
  • Heavy alcohol use: Chronic and heavy consumption of alcohol damages the pancreas and can cause both acute and chronic pancreatitis.
  • Certain medications: Some drugs like estrogen supplements, diuretics, immunosuppressants, azathioprine, and others can trigger pancreatitis.
  • High triglyceride levels (hyperlipidemia) or high calcium levels (hypercalcemia) in the blood.
  • Infections: Viral infections (like mumps, cytomegalovirus, hepatitis B), bacterial infections, or parasites.
  • Trauma or injury to the abdomen.
  • Structural problems with the pancreatic or bile ducts.
  • Genetic causes or hereditary disorders of the pancreas.
  • Autoimmune diseases.
  • Procedures such as endoscopic retrograde cholangiopancreatography (ERCP).
  • Pancreatic cancer, pancreas divisum, and other less common causes.

Acute pancreatitis is most often caused by gallstones or heavy alcohol use. Chronic pancreatitis more commonly arises due to long-term alcohol abuse, but can also be caused by hereditary factors, autoimmune diseases, and other factors listed above. In some cases, the exact cause of pancreatitis cannot be determined, known as idiopathic pancreatitis. The mechanisms behind pancreatitis typically involve premature activation of pancreatic enzymes inside the pancreas itself, which then start digesting pancreatic tissue, causing inflammation and damage. Thus, pancreatitis results primarily from blockage, injury, toxins (like alcohol), infections, or genetic predispositions that lead to pancreatic inflammation and enzyme activation. Severe cases can cause systemic effects and complications. This overview summarizes the key causes and mechanisms of pancreatitis based on current medical understanding.
