pancreas that worsens lying down

Overview

Pancreatitis is inflammation (swelling) of the pancreas, a gland behind your stomach that helps digest food and control blood sugar. When the pancreas is inflamed, lying flat can make the pain worse, while sitting up or leaning forward often feels better.

Acute pancreatitis is a common reason for hospital stays, affecting many adults each year. Chronic pancreatitis is less common but can develop after repeated episodes.

It can happen to anyone, but it is more common in adults between 30 and 60 years old. Men are slightly more likely to get it, especially from alcohol use.

Symptoms

Common symptoms

• Severe upper abdominal pain that may radiate to your back
• Pain that worsens when lying down and improves when sitting or leaning forward
• Nausea and vomiting
• Tender or swollen belly
• Fever and chills
• Rapid pulse

Symptoms in children

• Symptoms are similar to those in adults: abdominal pain, vomiting, and fever
• Pain may be less specific, and children may seem irritable or refuse to eat

Symptoms in older adults

• Older adults may have less obvious pain or feel generally unwell
• Confusion or dizziness can occur
• They are at higher risk for complications like dehydration

Causes

Main causes

• Gallstones that block the pancreatic duct – the most common cause
• Heavy alcohol use – a leading cause of chronic pancreatitis
• High levels of triglycerides (fats) in the blood
• Certain medications that can irritate the pancreas
• Infections, such as mumps or viruses
• Injury to the abdomen or surgery

Risk factors

• Having gallstones or a family history of gallstones
• Drinking large amounts of alcohol regularly
• Smoking tobacco
• Being overweight or having obesity
• Having high blood triglyceride levels
• Taking certain medicines (ask your doctor which ones may be a risk)
• Having a family history of pancreatitis

When to see a doctor

See a doctor urgently if:

• Go to the emergency department or call your local emergency number if you have severe belly pain, vomiting, or signs of infection.

Book a routine appointment if:

• Make a doctor's appointment if you have mild but persistent belly pain, especially if it gets worse when you lie down or after eating.

Diagnosis

Your doctor will ask about your symptoms and medical history, perform a physical exam, and order tests to check for inflammation and the cause.

Tests that may be done

• Blood tests – to measure levels of pancreatic enzymes (amylase and lipase) and check for infection or other issues
• Ultrasound – to look for gallstones or swelling
• CT scan – a detailed X-ray that can show inflammation, fluid collections, or damage
• MRI – sometimes used to get clearer images of the pancreas and bile ducts

What to expect at your appointment

If your doctor suspects pancreatitis, you will likely be admitted to the hospital for monitoring and treatment. Tests are usually done in the emergency room or hospital, and they may be repeated to follow your progress.

Treatment

Treatment aims to rest the pancreas, manage pain, and treat the underlying cause. Most people with acute pancreatitis need to stay in the hospital for a few days.

Self-care at home

• Stop eating and drinking for a short time (as advised by your doctor) to let your pancreas rest
• Once you can eat again, start with clear liquids and low-fat foods
• Avoid alcohol completely – even small amounts can worsen damage
• Take pain relievers as prescribed – do not use over-the-counter medications without asking your doctor

Medical treatments

In the hospital, you may receive intravenous (IV) fluids to prevent dehydration, pain medication, and nutrition through a tube if you cannot eat for several days. If infection is present, antibiotics will be given. Your medical team will also treat the cause, such as removing gallstones or lowering triglycerides with medication.

When is surgery considered?

If gallstones are causing pancreatitis, you may need surgery to remove the gallbladder (cholecystectomy) after the acute attack resolves. In severe cases, surgery may be needed to drain fluid collections or remove damaged tissue.

Living with this condition

After recovery, you will likely need to make long-term changes to prevent another attack. This includes eating a healthy diet, avoiding alcohol, and managing any underlying conditions.

Lifestyle tips

• Quit smoking – it increases your risk of pancreatitis and complications
• Limit or avoid alcohol entirely
• Maintain a healthy weight through balanced diet and regular activity
• Take all prescribed medications exactly as directed

Diet and exercise

Follow a low-fat diet with small, frequent meals. Avoid fried foods, rich sauces, and fatty meats. Eat plenty of fruits, vegetables, whole grains, and lean protein. Gentle exercise, like walking, can help with digestion and overall health, but avoid strenuous activity until your doctor says it's safe.

Mental health and emotional wellbeing

Living with a chronic condition or the fear of another attack can cause anxiety, depression, or stress. It is important to talk about your feelings with your healthcare team or a mental health professional.

Prevention

You can reduce your risk by not drinking excessive alcohol, maintaining a healthy weight, managing high cholesterol or triglycerides, and treating gallstones early. If you have a family history, ask your doctor about screening.

Screening programmes

Regular blood tests to check triglycerides and cholesterol may be recommended if you have risk factors. Imaging tests are not routine but may be used if you have symptoms.

Complications

If left untreated

• Pancreatic necrosis (tissue death) that can become infected
• Pseudocysts – fluid-filled sacs that can block ducts or rupture
• Organ failure (kidneys, lungs, or heart)
• Chronic pancreatitis with permanent damage and ongoing pain
• Malnutrition from poor digestion

Long-term outlook

Most people with acute pancreatitis recover fully with prompt treatment. However, severe cases can be life-threatening. With careful management and lifestyle changes, many people can prevent future attacks and live a full life.
