Introduction 

Chronic pancreatitis is a condition where the pancreas becomes permanently damaged due to inflammation.

It is different to acute pancreatitis, where the inflammation is only short-term.

The most common symptom of chronic pancreatitis is repeated episodes of abdominal (tummy) pain, which can be severe.

Other symptoms tend to develop as the damage to the pancreas progresses, such as producing greasy, foul-smelling stools.

When to seek medical advice

Always visit your GP if you are experiencing severe pain – it is a warning sign that something is wrong.

Why it happens

Long-term alcohol misuse is responsible for around 7 out of every 10 cases of chronic pancreatitis. This is because heavy drinking over a number of years can repeatedly damage the pancreas.

Less common causes include:

  • smoking, which can also increase the risk of alcohol-related chronic pancreatitis
  • a problem with the immune system that causes it to attack the pancreas
  • an inherited genetic mutation that disrupts the functions of the pancreas

In about 2 in every 10 cases, no specific cause is identified.

Who is affected

Chronic pancreatitis can affect people of any age, but is most common in middle-aged men aged between 45 and 54.

Between 2012 and 2013, over 35,000 people visited hospitals in England with the condition.

How it is treated

In most cases of chronic pancreatitis, there is no specific treatment to reduce the inflammation and repair the damage to the pancreas.

Therefore, treatment mainly focuses on lifestyle changes (see below) and medication to relieve the pain. Surgery is sometimes needed to treat severe chronic pain that does not respond to painkillers.

However, the pain can be difficult to treat and can seriously affect your quality of life.

People who do not smoke cigarettes and who avoid drinking alcohol tend to experience less pain and live longer than those who continue to drink and smoke after receiving a diagnosis.

Complications

Diabetes is a common complication of chronic pancreatitis and affects about half of people with the condition. It occurs when the pancreas is damaged and is unable to produce insulin.

People with chronic pancreatitis also have an increased risk of developing pancreatic cancer.

Anatomy of the abdomen 

The pancreas

The pancreas is a small, tadpole-shaped organ located behind the stomach and below the ribcage. It has two important functions:

  • it produces digestive chemicals (enzymes) used by the intestines to help digest food
  • it produces powerful hormones – the most important being insulin, which regulates the levels of sugar (glucose) in the blood
