Complications

Pancreatitis can cause serious complications, including:

• Kidney failure. Acute pancreatitis may cause kidney failure, which can be treated with dialysis if the kidney failure is severe and persistent.
• Breathing problems. Acute pancreatitis can cause chemical changes in your body that affect your lung function, causing the level of oxygen in your blood to fall to dangerously low levels.
• Infection. Acute pancreatitis can make your pancreas vulnerable to bacteria and infection. Pancreatic infections are serious and require intensive treatment, such as surgery to remove the infected tissue.
• Pseudocyst. Acute pancreatitis can cause fluid and debris to collect in cystlike pockets in your pancreas. A large pseudocyst that ruptures can cause complications such as internal bleeding and infection.
• Malnutrition. Both acute and chronic pancreatitis can cause your pancreas to produce fewer of the enzymes that are needed to break down and process nutrients from the food you eat. This can lead to malnutrition, diarrhea and weight loss, even though you may be eating the same foods or the same amount of food.
• Diabetes. Damage to insulin-producing cells in your pancreas from chronic pancreatitis can lead to diabetes, a disease that affects the way your body uses blood sugar.
• Pancreatic cancer. Long-standing inflammation in your pancreas caused by chronic pancreatitis is a risk factor for developing pancreatic cancer.
