What is the main cause of acute pancreatitis?

The main causes of acute pancreatitis can vary, but the two most common causes are gallstones and excessive alcohol consumption.

  1. Gallstones: Gallstones are a common cause of acute pancreatitis, particularly in developed countries. The gallbladder, located near the pancreas, stores bile produced by the liver. If a gallstone obstructs the common bile duct, which connects the liver and the pancreas, it can lead to inflammation of the pancreas. This blockage disrupts the normal flow of digestive enzymes, causing them to accumulate and activate within the pancreas, leading to pancreatitis.
  2. Alcohol consumption: Chronic and excessive alcohol consumption is another major cause of acute pancreatitis. Alcohol can cause direct damage to the pancreas and disrupt the normal functioning of enzymes. The exact mechanism by which alcohol induces pancreatitis is not fully understood, but it is believed to involve a combination of toxic effects on pancreatic cells, increased pressure within the pancreas, and abnormal activation of digestive enzymes.

Other less common causes of acute pancreatitis include:

  • Trauma or injury to the pancreas: This can occur due to accidents, surgical complications, or physical trauma to the abdomen.
  • Medications: Certain medications, such as certain antibiotics, immunosuppressants, diuretics, and some chemotherapy drugs, have been associated with pancreatitis in rare cases.
  • High levels of triglycerides: Extremely high levels of blood triglycerides, a type of fat, can cause acute pancreatitis.
  • Infections: In rare cases, infections like mumps or tuberculosis can lead to pancreatitis.
  • Genetic factors: In some instances, genetic factors and inherited conditions can increase the risk of developing pancreatitis.

It’s important to note that in some cases, the exact cause of acute pancreatitis may not be identified, and it is classified as idiopathic pancreatitis.
