Ulcerative Colitis

What is ulcerative colitis?1,2

Ulcerative colitis is an autoimmune disease that causes inflammation and sores
in your large intestine. It belongs to a group of conditions known as inflammatory bowel diseases, or IBD, and can develop at any age – although it is more likely to develop in people between the ages of 15 and 30.

Ulcerative colitis may damage your intestine and your body may not be able to absorb enough nutrients to keep you nourished.

What are the common symptoms of ulcerative colitis?1,2

The symptoms of ulcerative colitis vary from person to person. They may be constant, or may come and go every few weeks or months – when symptoms come back, it’s called a ‘flare-up’. There’s no way to predict when flare-ups will happen.

The most common symptoms of ulcerative colitis include:

  • Diarrhoea with blood, mucus or pus in your stool
  • Cramping and pain in your belly
  • A constant and/or urgent need to defecate
  • Inability to defecate despite urgency with rectal pain
  • Feeling sick, tired and losing weight
  • Fever

What causes ulcerative colitis?

Ulcerative colitis is complex and involves many factors, affecting about the same number of men and women. Ulcerative colitis can be triggered by a viral or bacterial infection; your immune system mistakes harmless bacteria as a threat and attacks the large intestine, causing it to become inflamed.

Ulcerative colitis seems to run in families, as it is more common in people who have relatives with the disease.1 Common triggers include:2,3

  • Certain medications such as pain relievers and antibiotics
  • Emotional stress
