Epiploic Appendagitis

Overview

Epiploic appendagitis (say: eh-pih-PLOH-ik uh-PEN-duh-JY-tis) is a condition where one of the small fatty pouches that hang off the outside of your large bowel becomes inflamed. These pouches are called epiploic appendages. They are tiny, finger-like flaps of fat attached to the surface of the colon (the large bowel), and most people have dozens of them. When one of these pouches gets twisted or its blood supply gets blocked, it becomes sore and swollen. This causes a sharp, focused pain in your belly. The good news is that epiploic appendagitis is not dangerous, is not an infection you can pass on, and almost always gets better by itself within days to a couple of weeks.

It is uncommon. It is thought to be found in a small number of people who go to an emergency department or clinic with sudden belly pain, and it is often only recognised because a scan is done. Many doctors believe it happens more often than we know, because mild cases may settle without anyone ever having a scan.

It mostly affects adults, and it is seen most often in people in their 40s and 50s. It can happen at any adult age. It is very rare in children. People who carry extra weight around the middle seem to be affected more often, though anyone can get it.

Symptoms

Common symptoms

• Sudden, sharp pain in one spot in the belly, which often starts without warning
• The pain is usually in the lower left side, but it can also be in the lower right side
• The sore spot is tender to touch, and pressing on it feels worse
• Pain gets worse when you move, cough, sneeze, or take a deep breath
• The pain stays in one place rather than spreading around the whole belly
• Most people do not feel sick or throw up, and their appetite and bowel habits are usually normal
• A mild raised temperature is possible but a high fever is not typical

Symptoms in children

• This condition is very rare in children
• If it does happen, a child may simply say their tummy hurts and point to one spot
• Younger children may be unsettled, cry when the tummy is touched, or refuse to walk or bend normally
• Because children cannot always describe the pain, any child with severe or lasting belly pain should be seen by a doctor

Symptoms in older adults

• Pain and tenderness are usually the same as in younger adults
• Because other belly problems such as diverticulitis are more common with age, a scan is often needed to tell the difference
• Some older adults may feel less intense pain than expected, so it is important to report any new, lasting belly pain
• If you take blood thinners or have other long-term conditions, tell the doctor, as this may affect your care

Causes

Main causes

• Twisting (torsion) of a small fatty pouch on the outside of the bowel, which cuts off its own blood supply
• A small blood clot blocking a vein inside the pouch, so the tissue becomes starved of oxygen and inflamed
• Inflammation of the pouch for other reasons, which makes it swollen and sore

Risk factors

• Carrying extra weight, especially around the middle of the body
• Being an adult in mid-life, most often in the 40s or 50s
• Having a longer or more mobile section of the fatty pouches, which makes twisting more likely
• Previous surgery or scarring in the belly, which can create points where tissue catches or twists
• There is no evidence that food, stress, or lifestyle choices directly cause it

When to see a doctor

See a doctor urgently if:

• You have new, sharp belly pain that lasts more than a few hours or is getting worse
• The pain is in the lower right side and you also feel sick or have a temperature — this needs checking quickly to rule out appendicitis
• You have a fever with belly pain
• You cannot eat or drink normally because of the pain

Book a routine appointment if:

• The pain has mostly settled but you want to talk it through and check you are recovering as expected
• You have had a scan that showed epiploic appendagitis and you have questions about what it means
• The pain is mild but keeps coming back over weeks
• You want advice about pain relief or about returning to exercise and work

Diagnosis

A doctor will ask about your pain — where it started, how it feels, and what makes it better or worse — and then gently press on your belly to find the tender spot. Because the symptoms of epiploic appendagitis look very like other belly problems, the usual way to confirm it is a CT scan (a detailed 3D X-ray picture of the inside of the belly). On the scan, the inflamed fatty pouch has a typical appearance that doctors can recognise. Sometimes an ultrasound scan is used instead, especially in thinner people or in children. Blood tests are often normal, which itself is a helpful clue.

Tests that may be done

• A physical examination of the belly, checking exactly where it hurts
• Blood tests, which are usually normal or only mildly changed
• A CT scan of the abdomen and pelvis, which is the most reliable test
• An ultrasound scan as an alternative in some people
• Urine tests to rule out a urine or kidney problem
• Occasionally other tests if the scan is unclear, to rule out other causes

What to expect at your appointment

The process usually happens in a hospital emergency department or an urgent care setting, because sudden severe belly pain needs a proper look. From arriving to getting an answer often takes a few hours. You may be asked not to eat or drink for a while in case other tests are needed. Getting a clear diagnosis is genuinely useful: it means you can be spared unnecessary antibiotics, hospital stays, or surgery that would have been offered if the problem had been diverticulitis or appendicitis.

Treatment

For most people, epiploic appendagitis needs no special treatment beyond managing the pain and letting the body heal. It is a self-limiting condition, which means it settles on its own. Doctors usually advise simple pain relief, rest, and a check-up if things do not improve. Antibiotics are not needed because it is not an infection. Hospital admission is usually not required once the diagnosis is clear and you are otherwise well.

Self-care at home

• Take pain relief as advised by your doctor or pharmacist — ask them which option is safe for you, especially if you have other health conditions
• Rest for the first few days, and avoid heavy lifting, straining, or vigorous exercise while it is sore
• Use gentle movement, such as short walks, as the pain allows, to keep your bowels moving
• Try a warm compress or hot water bottle on the sore area for comfort
• Drink plenty of fluids and eat light, regular meals; there is no special diet needed
• Keep a note of how the pain changes over the first week so you can report any change clearly
• Return to normal activity gradually rather than all at once

Medical treatments

Treatment is focused on comfort. Your doctor may suggest a pain reliever and, if the pain is severe, a stronger painkiller on prescription for a short time. They will consider which option is safe for you, taking into account your other medicines, allergies, kidney and stomach health. If you are sent home, you will usually be given clear advice about what to do if the pain gets worse and when to come back. Follow-up is often not needed if you improve steadily, but your doctor may ask you to check in after a week or two.

When is surgery considered?

Surgery is almost never needed for epiploic appendagitis. It may be considered only in rare situations — for example, if the diagnosis is genuinely unclear and another serious problem such as appendicitis cannot be ruled out, or if a rare complication such as an abscess or a blocked bowel develops. If surgery is suggested, ask your surgeon to explain exactly why it is needed in your case.

Living with this condition

Most people feel much better within a few days and are back to normal within one to two weeks. During that time, listen to your body: do what you comfortably can and rest when the pain flares. You can usually work from home or do light duties, but heavy physical work may need a short break. The pain can be sharp and unsettling at first, so it helps to know that it is expected to ease rather than get worse.

Lifestyle tips

• Keep gently active — short daily walks help your gut and your mood
• Avoid straining on the toilet; if you feel constipated, ask your pharmacist about a gentle solution
• Aim for a healthy, balanced way of eating with plenty of fibre and fluids, which is good for the bowel in general
• If you carry extra weight, gradual, sensible weight loss is good for your overall health, though it is not a guaranteed way to prevent this condition
• Pace your return to sport and heavy chores over a week or two rather than all at once

Diet and exercise

There is no special diet for epiploic appendagitis. Eat normally as your appetite returns, and keep meals light and regular while the pain is fresh. Fibre and fluids help keep stools soft, which is comfortable for the bowel. Gentle exercise such as walking is fine as soon as it feels okay. Wait until you are pain-free before going back to running, heavy lifting, contact sports, or core workouts, and build up slowly.

Mental health and emotional wellbeing

Sudden, severe belly pain is frightening, and being told you need a scan can be stressful. Many people feel anxious while waiting for results or worry that something serious has been missed. It can help to remember that this condition has a clear, reassuring explanation and a good outcome. If worry, low mood, or poor sleep is lasting more than a couple of weeks, talk to your doctor — support is available, and you do not have to cope alone. If you ever feel overwhelmed or in crisis, contact your local crisis service or emergency number straight away.

Prevention

There is no proven way to prevent epiploic appendagitis, because it happens when a small fatty pouch twists or loses its blood supply — something that is largely down to chance and body shape. Looking after your general health, staying active, and keeping to a healthy weight are good for your bowel and overall wellbeing, even though they cannot guarantee this will not happen again. Having it once does not make you more likely to get it again, though a small number of people do have a repeat episode.

Screening programmes

There is no screening test for epiploic appendagitis. It is found when someone has symptoms and a scan. Routine bowel screening programmes for other conditions, such as bowel cancer screening offered by national health services, are separate and still worth attending when invited.

Complications

If left untreated

• In most people, nothing — the inflamed pouch heals by itself and the pain fades
• Rarely, the inflamed pouch can form a small collection of pus (an abscess)
• Rarely, the sore pouch can become stuck to the bowel and cause a blockage or a twisting problem
• Rarely, scar tissue (adhesions) can form in the belly
• The main risk is not the condition itself but the chance that a more serious cause of the pain is missed — which is exactly why a scan is often done

Long-term outlook

The outlook is very good. Epiploic appendagitis is a harmless, self-healing condition, and the great majority of people recover fully within one to two weeks with nothing more than pain relief and rest. It does not raise your risk of bowel cancer and it does not damage your digestion. Once the pain has gone, you can put it behind you and carry on as normal.
