Chronic Pancreatitis: Symptoms and Treatment
Reviewed by Yevheniia Anatoliivna Minchuk, Gastroenterologist of the highest category, Dietitian updated: 11 December 2025
What Chronic Pancreatitis Is and What Changes Occur in the Pancreas
Chronic pancreatitis is a long-term inflammation of the pancreas in which healthy tissue is gradually replaced by scar tissue. This disrupts the gland’s two main functions: producing digestive enzymes and hormones, including insulin. Unlike acute pancreatitis, which occurs suddenly, the chronic form develops gradually, with periods of flare-ups and remission, and the tissue changes are irreversible. Over time, progressive tissue damage can lead to lasting digestive and endocrine problems.
Why Chronic Pancreatitis Develops
The most common cause of chronic pancreatitis is long-term alcohol abuse. The disease can also develop due to gallstone disease, fat metabolism disorders, genetic predisposition, autoimmune processes, or as a result of repeated episodes of acute pancreatitis. In some patients, the exact cause cannot be determined.
Symptoms of Chronic Pancreatitis: How the Disease Manifests
| Symptom | How It Manifests | What It May Indicate |
|---|---|---|
| Upper abdominal pain | Dull, band-like, worsens after eating | Flare-up of the inflammatory process |
| Digestive disturbances | Bloating, fatty stools, nausea | Pancreatic enzyme insufficiency |
| Weight loss | Gradual decrease in body weight | Impaired nutrient absorption |
| Elevated blood sugar | Thirst, frequent urination | Impaired insulin production |
| General weakness | Fatigue, reduced ability to work | Chronic inflammatory process |
How Chronic Pancreatitis Is Diagnosed
Diagnosis includes blood tests for pancreatic enzyme levels, a stool test for elastase to assess enzymatic function, and blood glucose levels. Abdominal ultrasound, CT, or MRI is used to assess structural changes in the organ. These methods can detect calcifications, cysts, or narrowing of the pancreatic ducts typical of a chronic process, and help track the disease over repeated exams.
Treatment of Chronic Pancreatitis and Nutrition During Remission
The basis of treatment is a diet limiting fatty foods and complete avoidance of alcohol, along with enzyme replacement medication to compensate for reduced gland function. For significant pain, painkillers are prescribed. If conservative treatment is ineffective or complications arise — cysts, duct narrowing, or suspicion of a malignant process — general surgery may be needed. In many cases, the procedure is performed as laparoscopic surgery, which reduces the invasiveness of the operation.
Because chronic pancreatitis increases the risk of malignant changes in the pancreas and is often associated with peptic ulcer disease, surgical treatment of pancreatic cancer or surgical treatment of stomach ulcers may be needed when indicated.
When Symptoms of Chronic Pancreatitis Require Urgent Medical Care
Urgent medical consultation is needed for: sudden, unbearable abdominal pain, repeated vomiting, signs of dehydration, fever, and a sharp deterioration in general condition. These symptoms may indicate a flare-up of the disease or the development of complications that require immediate intervention.
