Using Laser Treatment To Help You Quit Smoking

Hemorrhoids are caused by the veins in the rectum and anus becoming swollen and inflamed. The location of the piles can be internal or external and the symptoms vary dependent on this. If the hemorrhoids are internal, they can go undetected as pain receptors are not present internally. The only evidence of the problem can be blood in the bowel movements as they pass through the area. External piles are widely known to resemble a bunch of grapes and can be extremely painful for the sufferer. Of the two types, it would appear that internal hemorrhoids are the better of the two to have as you may not even know it. However, external piles can be easily treated whereas internal piles, when left undetected, can result in more serious complications.

If an internal hemorrhoid becomes severely distended over time it can be pushed out of the anus and so be visible externally. This is very unpleasant as it means that the internal passage is obstructed, making passing bowel movements difficult and painful. This is called prolapsed hemorrhoids. Once this has happened it is quite common for the anus to spasm and the sphincter can then trap the prolapsed hemorrhoid outside of the body. This then prevents the blood supply from reaching it and it becomes a strangulated hemorrhoid.
