Hemorrhoids in men can be caused by various factors, including:
- Straining during bowel movements
- Sitting for long periods of time, especially on the toilet
- Chronic diarrhea or constipation
- Obesity
- Pregnancy
- Anal intercourse
- Low-fiber diet
- Regularly lifting heavy items
- Aging, as the tissues that support the veins in the rectum and anus can weaken and stretch
These factors can lead to increased pressure in the lower rectum, which can cause the veins or blood vessels in the anus and lower rectum to become swollen and irritated, resulting in hemorrhoids.
