Pregnancy may increase the risk of developing piles, as it causes increased pressure in the body.
Piles are caused by increased pressure in the lower rectum.
The blood vessels around the anus and in the rectum will stretch under pressure and may swell or bulge, forming piles. This may be due to:
- chronic constipation
- chronic diarrhea
- lifting heavy weights
- pregnancy
- straining when passing a stool
The tendency to develop piless may also be inherited and increases with age.
