The health care practitioner will ask the patient questions about his or her symptoms, lifestyle and habits, and medical and surgical history.
- The physical exam will probably include a "digital
rectal examination" in
which a health care practitioner inserts a gloved finger into the rectum to try to find a cause for bleeding or pain.
- Blood tests may be performed to access signs of blood loss or infection,
evaluate the function of the kidneys and liver, or to rule out other medical
conditions that could be causing similar symptoms.
- X-rays of organs in the abdomen may be ordered to assist in identifying
the cause of the patient's symptoms.

procedure performed using a flexible tube with a tiny camera at the end, called an endoscope. The endoscope

rectum and colon. This procedure is relatively painless and takes about five
Sometimes diverticulosis is discovered during a screening colonoscopy. The American Cancer Society
and the United States Multi-Society Task Force on Colorectal Cancer recommend colonoscopies every 10 years for people older than 50 years to detect early signs of colon cancer. If
an individual's family medical history includes a close relative diagnosed with colon cancer,
they may need to begin screening at an earlier age. Consult a gastroenterologist for guidelines.
