Understanding Left-Sided Colitis with Rectal Bleeding

Left-sided colitis is a form of ulcerative colitis that specifically affects the left side of the colon. One of the common symptoms experienced by individuals with left-sided colitis is rectal bleeding. In this article, we will explore the causes, symptoms, and potential complications associated with this condition.

Causes

The exact cause of left-sided colitis is unknown, but it is believed to result from an abnormal immune response in the colon. Factors such as genetics, environmental triggers, and an individual's immune system may all play a role in the development of this condition.

Symptoms

1. Rectal bleeding: One of the hallmark symptoms of left-sided colitis is the presence of blood in the stool. This bleeding may range from mild to severe and can appear as bright red blood or dark, tarry stools.
2. Abdominal pain: Many individuals with left-sided colitis experience cramping or discomfort in the lower abdomen. This pain can vary in intensity and may come and go.
3. Diarrhea: Chronic or recurring episodes of loose, watery stools are common in left-sided colitis. This symptom may be accompanied by urgency or an inability to control bowel movements.
4. Weight loss: Some individuals may experience unintentional weight loss due to decreased appetite, malabsorption, or the body's increased energy expenditure during inflammation.

Potential Complications

If left-sided colitis is not properly managed, it can lead to various complications. These may include:

• Colon ulcers: The inflammation associated with left-sided colitis can cause ulcers to form in the lining of the colon.
• Strictures: Long-term inflammation may cause the colon to become narrowed, leading to a condition called strictures. This can result in bowel obstruction and further complications.
• Increased cancer risk: Individuals with left-sided colitis have a slightly higher risk of developing colon cancer compared to the general population. Regular screening is important to detect any precancerous or cancerous changes early.

In conclusion, left-sided colitis is a type of ulcerative colitis that primarily affects the left side of the colon. Rectal bleeding is a common symptom associated with this condition. If you are experiencing any of these symptoms, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate management.
