Causes

The veins around your anus tend to stretch under pressure and may bulge or swell. Hemorrhoids can develop from increased pressure in the lower rectum due to:

• Straining during bowel movements
• Sitting for long periods of time on the toilet
• Having chronic diarrhea or constipation
• Being obese
• Being pregnant
• Having anal intercourse
• Eating a low-fiber diet
• Regular heavy lifting
