Hemorrhoids in men are primarily caused by increased pressure in the lower rectum, which leads to swelling and irritation of the anal cushions-vascular structures important for continence. Key factors contributing to this increased pressure include:
- Straining during bowel movements , often due to constipation, which puts excessive pressure on the veins around the anus and rectum
- Sitting for long periods , especially on the toilet, which causes blood to pool and increases pressure in the anal area
- Heavy lifting or strenuous physical activity , common in men, which raises abdominal and rectal pressure and can cause hemorrhoidal vessels to swell
- Chronic diarrhea or constipation , both of which can irritate and strain the rectal veins
- Low-fiber diet and dehydration , leading to harder stools and more straining during defecation
- Age-related weakening of tissues in the anal area, making hemorrhoids more likely in middle-aged men (45–65 years)
- Other contributing factors may include obesity, prolonged sitting in sedentary lifestyles, genetics, and possibly pelvic floor dysfunction
In summary, hemorrhoids in men are mainly caused by increased pressure on the rectal and anal veins due to straining, prolonged sitting, heavy lifting, and bowel irregularities like constipation or diarrhea. Lifestyle factors such as diet and hydration also play a significant role
