Left Side Colon Inflammation: Common Symptoms and What You Need to Know

When inflammation occurs in the left side of the colon, individuals may experience a variety of symptoms including left-sided abdominal pain, bloating, diarrhea, and irregular bowel movements. The colon is divided into several sections — ascending colon, transverse colon, and descending colon. The left side of the colon primarily refers to the descending colon and sigmoid colon, where formed stool is stored before elimination.

During digestion, waste material reaches the descending colon already semi-solid, and it remains in the sigmoid colon until defecation. When inflammation affects this area, inflammatory factors may be released, irritating the smooth muscles of the intestinal wall. This irritation often leads to pain localized on the left side of the abdomen, which can vary in intensity depending on the severity of the inflammation.

In addition to pain, inflammation can disrupt normal fluid absorption in the colon, leading to loose or watery stools and an increased frequency of bowel movements. Gas buildup may also occur due to impaired gas absorption, resulting in a persistent feeling of fullness or bloating.

Another notable symptom is changes in bowel habits, such as urgent or frequent trips to the bathroom, and sometimes mucus or blood in the stool. These signs should not be ignored, especially if they persist or worsen over time.

If you're experiencing recurring discomfort or digestive issues, it's important to consult a healthcare professional for proper diagnosis and treatment options.
