What Should We Know about Ulcerative Colitis?

What should we know about ulcerative colitis?

There are three parts I want to introduce here: the definition of ulcerative colitis, the causes or risk factors and the symptoms or signs.


Ulcerative colitis is an inflammatory bowel disease (IBD) that causes long-lasting inflammation and sores in your digestive tract.

Ulcerative colitis also can also cause inflammation in joints, spine, skin, eyes, and the liver and its bile ducts. Long-lasting ulcerative colitis is a risk factor for colon cancer.

Causes and risk factors:

The exact cause of ulcerative colitis remains unknown. The possible causes may include immune system malfunction and heredity or family history of it.

Immune system malfunction means the abnormal immune system attacks the cells in the digestive tract instead of the invading virus or bacterium.

Heredity means you may at a higher risk of developing ulcerative colitis if you have relatives with this disease.


Depending on the severity of inflammation and the place it occurs, ulcerative colitis symptoms can vary. The common symptoms and signs include:

  • Rectal pain
  • Inability to defecate despite urgeny
  • Weight loss
  • Fatigue
  • Fever
  • Rectal bleeding—small amount of blood in stools
  • Abdominal pain and cramping
  • Diarrhea
  • Failure to grow in children
  • Dehydration
  • shock

If you have the symptoms above, please find a doctor as soon as possible.
