Ulcerative Colitis

Ulcerative colitis is a long term condition caused by inflammation of the colon and the rectum. It can spread from the lower part of the colon to where the large and small intestine joins.

Small ulcers can develop on the colon’s lining. It is associated with dysfunction of the immune system.

Around 146,000 people in the UK have ulcerative colitis and it normally develops between the ages of 15 and 25 or between 55 and 65. It can strike at any time and is slightly more common in men than women.

It is a lifetime condition but can follow a relapsing and remitting pattern, meaning the symptoms can disappear for months or even years although most people experience flare-ups once a year.

What is ulcerative colitis?

Ulcerative colitis causes inflammation of the colon, which can spread from the lower part of the colon to where the large and small intestine joins.

Causes of ulcerative colitis

The condition is thought to be the result of a problem with the immune system which mistakenly attacks healthy tissue causing inflammation. One theory is that the immune system wrongly identifies friendly bacteria in the colon as a harmful infection. Certain viral or bacterial infections could also trigger the condition.

Inherited genes are a factor with research stating that one in four people with ulcerative colitis will have a family history of the condition.

Environmental factors also come into play with, for example, the condition is more common in urban areas of northern parts of Western Europe and America.

Various environmental factors that may be linked to ulcerative colitis have been studied, including air pollution, medication and certain diets

Symptoms of ulcerative colitis

There may be long periods without symptoms but the main issue is diarrhoea which may have blood or mucus in it. You may have lower abdominal pain or cramps and rush to the toilet.

Other symptoms include fatigue, losing appetite and weight, a high temperature and the need to go to the toilet but not passing any stools.

Some people also develop mouth ulcers, rashes and swollen skin, painful joints and irritated eyes. Most people cannot identify a specific trigger for the flare-up.

Diet is not thought to cause the condition, so it should not be confused with Irritable Bowel Syndrome.

  • Mucus and blood in stools
  • Cramps

Diagnosis of ulcerative colitis

A doctor will examine for paleness caused by anaemia and tenderness of the tummy caused by inflammation. A stool sample can be checked for signs of infection.

A gastroenterologist – a consultant specializing in the digestive system – might as for a colonoscopy which looks at the lining of your large bowel to check for any ulcers or inflammation in your bowel. A flexible sigmoidoscopy allows the doctor to look inside your rectum and the lower part of your bowel.

A biopsy may be needed for laboratory tests and this can be taken during the colonoscopy or sigmoidoscopy.

A CT or MRI scan can also show how much of your large bowel is affected by ulcerative colitis.

Treatment of ulcerative colitis

Ulcerative Colitis can be managed by medication which helps to reduce inflammation.

A range of medicines can be prescribed to control the symptoms and prevent flare-ups and these can be taken as tablets or a rectal suppository.

If the lower part of the colon only is infected it can be treated with suppositories or enemas.

Stronger medicines may be needed during flare-ups.

While there is no cure, medication can reverse the changes caused by colitis and return the lining of the colon to normal, but inflammation can recur at any time. Preventative medicines reduce the risk of inflammation recurring.

Surgery to remove the colon may also be recommended if symptoms become severe.
