Hemorrhoids are swollen veins that occur in the rectum or around the anus. Hemorrhoids, sometimes called piles, are extremely common, occur for a variety of reasons, and can be effectively treated in a number of ways. Some of those affected will never suffer from symptoms, while others will experience itching, pain, and bleeding, especially when passing stool. Veins around the anus stretch or swell when under pressure; therefore, hemorrhoids occur for many reasons. The following are a few common reasons that a patient may develop hemorrhoids:
As people age, they become more susceptible to hemorrhoids as their veins become more fragile. Most patients will never know exactly why they are experiencing hemorrhoids or the uncomfortable symptoms that accompany them:
These symptoms will vary, depending on the location of the hemorrhoid. For example, internal hemorrhoids occur within the rectum, and typically cause no pain or swelling, but will bleed. However, an external hemorrhoid will become irritated and painful, and can even pool blood, forming what is called a thrombosed hemorrhoid. Thrombosed hemorrhoids are typically the most painful.
