I have piles from last 15 years now whenever i get constipation it bleeds and causes body pain.is surgery the best way or any other solution can work.

Sounds like its : Time to see a surgeon and get rid of them.

Yes: A simple office procedure is usually all that is necessary. If the hemorrhoids (piles) are internal rubber bands can be placed around them with a special instrument and they fall off over the next few days.

It depends: Occasional bleeding does not require surgery. Avoid straining, especially to get done fast. Increase fiber and liquid intake to prevent constipation. If your stools are soft/easy to pass every time and still bleed, then you need surgery. By avoiding forcing out hard, constipated stools, you may see piles shrink/resolve. But don't let it get to where they're constantly out. Early surgery=less pain.
