Important facts about UC

UC is a chronic condition where: 

  • Your immune system mistakenly harms healthy cells in the inner lining of the large intestine, or colon

  • The overactivity of the immune system causes excess inflammation in your colon

  • Too much inflammation can lead to colon damage and UC symptoms

This inner layer is called the epithelial tissue, which is found throughout the body. It protects your body’s organs, as well as performs secretory, transport, and absorption functions.

An organ in the digestive system that absorbs water and other elements from partially digested food to form stools that are passed out of the body. The colon is also known as the large intestine.

Some common UC symptoms:

Sudden accidents

Abdominal pain

Frequent bathroom trips

Bloody stools


Your gastroenterologist may also use the term "urgency" to describe not being able to wait to use a bathroom

What causes UC?

The exact cause of UC is unknown, but it can be influenced by many different factors, including:

  • A person’s immune system

  • Genetics

  • Other environmental factors

UC shouldn’t take charge of your life

The severity of your symptoms may be a sign of ongoing inflammation in your colon.
