Colon: From the appendix to approximately the start of the sigmoid colon
Dr. Arthur Sgalia
Internal Medicine 48 years experience
Ascending, transvers: The entire colon consists of the ascending, the transfers, and the descending colon. The proximal two thirds consist of the ascending and transfers portions. The ascending portion runs along the right side of your abdomen from the area here your appendix out to your right rib cage margin. The transverse colon runs from just under your ribs on the right across to just under your ribs on the left. The descending colon runs down the left side of your abdomen.

Proximal colon: Colon starts from the right side where the appendix is located and becomes the ascending colon, then the middle part the transverse colon, then on the left side is the descending colon then the sigmoid and ends with the rectum. The proximal part of the colon is the right side of the colon ( the ascending colon).

A 27-year-old member asked:

Does my colon need to be cleansed periodically for me to stay in good health?

2 doctor answers2 doctors weighed in
Dr. Ronald Kline
Specializes in Colon and Rectal Surgery
No: Colon cleansing will remove the normal bacteria in the colon and can lead to overgrowth of harmful bacteria. Stool bulking agents such as fiber, psyllium, or products such as MiraLAX (polyethylene glycol) work to promote natural evacuation of the tract. Probiotics will help maintian the natural flora. A well-balanced diet also will promote normal bowel function.
A 26-year-old member asked:

What could be the probable diagnosis of a growth at sigmoid colon and rectm junction?

3 doctor answers15 doctors weighed in
Dr. Douglas Purdy
Gastroenterology 33 years experience
Growth=Polyp=Tumor: A growth in the colon, also called a polyp, is a tumor or growth of abnormal tissue. They can be benign (non-cancerous) or cancer. Benign polyps such as adenomas have potential to turn to cancer if they grow a long time. Other polyps, such as hyperplastic, usually don't turn to cancer. Some polyps may already have cancer in them. Colonoscopy with biopsy is usually needed to make a diagnosis.
A 36-year-old member asked:

Are colon cleanses and colonics safe?

1 doctor answer3 doctors weighed in
Dr. Robert Kwok
Pediatrics 33 years experience
Not necessary: The colon is a place where water and some nutrients are absorbed by one's body. Diarrhea occurs if one does not absorb the normal amount of water and nutrients from his poop (stool). If one has bowel problems, he can see his primary care doctor or a gastroenterologist. Colonic cleaning or irrigation is not natural, and can be dangerous if the person's chemical balance is distorted.

Many and varied: Depending on the problem, signs can include nausea and vomiting, constipation, diarrhea, bleeding from the rectum, abdominal cramping, weight loss or gain or no symptoms at all. If you suspect some sort of problem with your colon, see your doc right away for an examination and evaluation.

Depending upon your age you should have a screening colonoscopy anyway (>50). We have markedly reduced the incidence of colon cancer in this manner.

Why are celebrities having colon cleanses?

Fashionable: There is no medical justification for this procedure. The colon itself actually needs stool to get nutrients and to have good health; a colon deprived of stool atrophies and becomes ill. So it's just an expensive fad with no documented evidence that it helps anything.
