Pancreatitis: A Comprehensive Patient Guide

Overview

The pancreas is a long, flat organ located behind your stomach that produces digestive enzymes to break down food and hormones like insulin that regulate blood sugar. Pancreatitis is inflammation of the pancreas, which can be acute (sudden onset, lasting days to weeks) or chronic (long-term, causing permanent scarring and damage). It ranges from a mild, self-limiting condition to a life-threatening emergency, so prompt medical evaluation is critical if you suspect you have pancreatitis.

Signs & Symptoms

The most common symptom of pancreatitis is severe, persistent upper abdominal pain that may radiate to your back, often worsening after eating, especially fatty meals. Other common symptoms include nausea, vomiting, fever, rapid pulse, and a swollen or tender abdomen. In severe or chronic cases, you may experience jaundice (yellowing of the skin and eyes), unintentional weight loss, or oily, foul-smelling stools (called steatorrhea) caused by poor digestion of fats.

Causes & Risk Factors

Acute pancreatitis is most often caused by gallstones (which block the pancreatic duct) or heavy alcohol use. Less common causes include very high triglyceride levels, certain medications (such as some blood pressure or antibiotic drugs), abdominal injury, or viral infections. Chronic pancreatitis is most frequently linked to years of heavy alcohol use, but can also be caused by autoimmune conditions, genetic mutations, or repeated episodes of untreated acute pancreatitis. Risk factors for developing pancreatitis include a family history of the condition, smoking, obesity, and type 2 diabetes.

Diagnosis

Your healthcare provider will start with a physical exam and ask about your symptoms, medical history, alcohol use, and any medications you take. Blood tests are used to check for elevated levels of pancreatic enzymes (amylase and lipase), which are a key marker of pancreas inflammation. Imaging tests such as abdominal ultrasound, CT scan, or MRI may be ordered to look for gallstones, inflammation, or damage to the pancreas. In some cases, an endoscopic ultrasound (EUS) or pancreatic function test may be used to get more detailed information about the pancreas and its ducts.

Treatment & Management

Treatment for pancreatitis depends on the type (acute or chronic) and severity of your condition. For mild acute pancreatitis, treatment usually involves a short hospital stay for IV fluids, pain management, and fasting to allow the pancreas to rest. You may need a feeding tube if you cannot eat normally. Severe acute cases may require surgery to remove damaged tissue, drain fluid buildup, or treat gallstones. For chronic pancreatitis, treatment focuses on managing chronic pain, replacing missing digestive enzymes with prescription supplements, and addressing underlying causes such as alcohol use or high triglyceride levels. Some people may need procedures to open blocked pancreatic ducts or remove damaged tissue.

Living With It

If you have chronic pancreatitis, long-term lifestyle changes are essential to manage symptoms, prevent painful flare-ups, and slow progression of the disease. The most critical step is to stop drinking alcohol completely, as even small amounts can trigger inflammation and further damage. You will also need to follow a low-fat, high-protein diet, eat small frequent meals, and stay hydrated. Your provider may recommend vitamin and nutrient supplements, as chronic pancreatitis can make it difficult to absorb nutrients from food. Quitting smoking is also vital, as smoking accelerates pancreas damage and increases the risk of complications.
