Where Does Colitis Pain Occur?

Colitis refers to inflammation of the colon, and the location of the pain depends on which part of the colon is affected. The colon is anatomically divided into several sections: the ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. Each type of colitis can cause discomfort in a specific area of the abdomen.

Right lower abdominal pain is commonly associated with ascending colitis. This occurs because the inflamed tissue in the ascending colon irritates surrounding nerves, leading to localized discomfort in the lower right quadrant of the abdomen.

Transverse colitis typically causes upper abdominal pain. As this section of the colon crosses the upper abdomen, inflammation here may lead to a more generalized upper belly ache that can sometimes be mistaken for other gastrointestinal issues.

Descending colitis results in pain on the left side or lower left side of the abdomen. This is due to inflammation affecting the descending colon, which runs along the left side of the abdominal cavity, often causing noticeable tenderness in that region.

Sigmoid and rectal inflammation usually causes lower abdominal pain, particularly just above the pubic bone or behind the bladder on the left side. These areas are closely related to the anatomical position of the sigmoid colon and rectum, making them common sites for discomfort in these types of colitis.

It's also important to note that if the condition progresses to rectal cancer, patients may not always experience direct pain. Instead, they might feel a sensation of heaviness around the anus or pelvic discomfort. These symptoms should not be ignored, especially if they persist or worsen over time.
