Rectal bleeding is bleeding that can stem anywhere from the lower portion of the colon, to the rectum and the anal canal, which is the open that allows stool to pass. The color of blood associated with rectal bleeding can differ based on where the bleeding originates. Although most of the reasons men may experience rectal bleeding that is not serious, a doctor should always be contacted to determine the underlying cause.
Hemorrhoids
Hemorrhoids are swollen veins that develop in the rectum or anus. There are three types of hemorrhoids: internal, prolapsed and external. Internal hemorrhoids are located inside the rectum, prolapsed hemorrhoids start inside the anus but bulge outside of the opening and external hemorrhoids are located outside of the anus. Hemorrhoids develop as a result of increased pressure in the veins due to straining during bowel movements or being excessively overweight.
Symptoms of hemorrhoids include rectal bleeding, pain or burning around the anus and a tender lump. Most hemorrhoids go away on their own within one to two weeks, according to FamilyDoctor.org. At home care, such as application of creams and warm baths, can reduce severity of symptoms. In severe cases, surgery may be required to remove the hemorrhoids.
Anal Fissure
An anal fissure is a physical tear in the anus or anal canal. Anal fissure are often caused by injury to the anus from chronic constipation, straining during a bowel movement and persistent diarrhea. In some cases, an anal fissure can occur as a result of underlying digestive diseases, decreased blood flow to the anus and sexually transmitted diseases.
Symptoms of an anal fissure include rectal bleeding, pain during bowel movements, painful burning, itching around the anus and pain during urination. Treatment for anal fissures consists of stool softeners and keeping the area lubricated in an effort to reduce pressure on the anal sphincter and allow the fissure to heal. Rarely, surgery is used to repair anal fissures that do not heal with other treatments.
Colon Cancer
Colon cancer is uncontrolled cell growth that occurs in the colon, which is the lower part of the large intestine. Most cases of colon cancer begin as small growths called polyps that eventually develop into cancer. It is unclear what causes some people to develop polyps that turn into cancer, while others don't.
MayoClinic.com notes that symptoms of colon cancer usually do not appear until later stages of the cancer, so regular screening is recommended for older adults. Symptoms of colon cancer include rectal bleeding, change in bowel habits for more than two weeks, chronic abdominal pain and cramps, weakness, fatigue and unexplained weight loss. Treatment for colon cancer depends on the stage of the cancer, but generally consists of radiation therapy, chemotherapy and surgery to remove cancerous growths or entire portions of the colon.
