Ulcerative colitis

How can ulcerative colitis be prevented?

Flare-ups cannot be prevented, but the severity and extent of the attacks can be reduced.

It’s important that affected people follow preventive treatments carefully, watch out for symptoms and consult their doctor if there is blood in their stool.

How is ulcerative colitis diagnosed?

  • Stool specimens are collected for cultivation and microscopy to exclude infection caused by bacteria and parasites. Faecal calprotectin in conjunction with specific symptoms of ulcerative colitis can increase the accuracy of diagnosis before endoscopy.
  • The diagnosis is confirmed by means of an endoscopy in the large intestine and the rectum. Small tissue samples from the mucosa are usually obtained during the procedure, which can in many cases confirm the diagnosis.
  • An endoscopic examination of the entire large intestine (colonoscopy) or the lower bowel (sigmoidoscopy) is usual and other abdominal images, such as MRI or CT scan may also be needed.
  • Blood samples can help determine the severity of the inflammation, and show whether the patient suffers from anaemia (low haemoglobin count).
