What are piles?
Piles, also called hemorrhoids, are enlarged vascular cushions in or around the anal canal. These cushions are a normal part of the anatomy; they become a problem when they enlarge, bleed, prolapse or cause irritation.
Symptoms vary between patients, and so does severity. Some people have occasional bleeding and nothing more, while others have a lump that comes down each time they open their bowels. That difference is why the treatment that suits one patient may not suit another.
Piles vary in type and severity, which is established at examination.
