Chronic constipation is a frequent cause
(HealthDay News) -- Hemorrhoids occur when blood vessels in the rectum become swollen and tender.
The American Society of Colon and Rectal Surgeons says common risk factors for hemorrhoids include:
- Having chronic constipation or diarrhea, or pushing too hard during bowel movements.
- Being pregnant.
- Having family members who have had hemorrhoids.
- Sitting on the toilet for long periods.
- Overusing enemas or laxatives, which can trigger problems with bowel function.
