Proximal Colon

The proximal colon is a part of the large intestine that is involved in the process of digestion. It is located in the abdomen and is connected to the small intestine at one end and the distal colon at the other. The proximal colon is responsible for absorbing water and electrolytes from the partially digested food that enters it from the small intestine.

Anatomy

The proximal colon is made up of three main parts: the cecum, the ascending colon, and the transverse colon. The cecum is a pouch-like structure that receives the chyme from the ileum, the last part of the small intestine. The ascending colon travels up the right side of the abdomen, and the transverse colon travels across the abdomen.

Function

The main function of the proximal colon is to absorb water and electrolytes from the partially digested food that enters it from the small intestine. This helps to form the stool. The proximal colon also contains bacteria that help in the breakdown of undigested food particles.

Diseases and Conditions

There are several diseases and conditions that can affect the proximal colon. These include colorectal cancer, diverticulosis, inflammatory bowel disease, and irritable bowel syndrome. Symptoms of these conditions can include abdominal pain, changes in bowel habits, and blood in the stool.

Treatment

Treatment for diseases and conditions of the proximal colon can vary depending on the specific condition and its severity. Treatment options can include medication, lifestyle changes, and in some cases, surgery.
