1. Blood in the stool.
 
Perhaps the most alarming symptom, blood in the stool can also be a reason to get a colonoscopy. Often, blood in the stool due to problems in the colon is misinterpreted as being associated with hemorrhoids. Many people with hemorrhoids see blood in their stool because of inflammation of the rectum. Blood in the stool can also be missed because people identify it as red-colored food, like beets or tomatoes, instead of blood.

Once there is blood in the stool, however, it is a good idea to address that with your doctor. In many cases, doctors first will test a stool sample to be sure that it is indeed blood in the stool. After blood has been identified without a doubt, most doctors recommend a colonoscopy. However, it is your health, so you probably want to act in your best interest and have a colonoscopy.

Cause for a Colonoscopy

In reality, colon cancer does not have to be life-threatening if it is caught early on. However, colon cancer can be fatal if it has gone on too long. Getting a colonoscopy could identify colon cancer early enough that it can be removed or go into remission through chemotherapy. For this reason, you most likely want to have a colonoscopy done if you exhibit signs and symptoms like rapid weight loss, changes in bowel movements, reccurring and unattributed abdominal pain, and blood in the stool. Do not be afraid to ask your doctor about these symptoms and about getting a colonoscopy. Your health could depend on it.
