Hemorrhoids are the most common causes of rectal bleeding. They can occur from sitting in the toilet for long periods of time, forcing bowel movements, straining during a physical activity, heavy lifting, obesity, low-fiber diet or even from pregnancy.
Also referred to as piles, they are caused when the blood vessels in and around the anus become swollen or inflamed. These can develop in a cluster or in several distinct areas.
It is quite common for patients to experience both internal and external hemorrhoids simultaneously.

Should you experience any of the above symptoms that do not improve but instead deteriorate, it is highly recommended that you seek medical diagnosis at your earliest opportunity because symptoms of hemorrhoids and tumors are so similar to those associated with colon cancer. This will ensure that any disorder can be identified at the outset, thereby giving any subsequent treatment a much higher chance of success.
