Are hemorrhoids more common in males than in females?

Hemorrhoids are not more common in males than in females, according to MedicineNet. Hemorrhoids occur in everyone, but doctors consider them abnormal when they enlarge and cause problems. Problematic hemorrhoids occur in men and women equally, typically between ages 45 and 65.

Approximately 4 percent of the general population suffers from hemorrhoid problems, notes MedicineNet. Doctors believe hemorrhoids occur when blood flow to the veins is blocked due to severe pressure on the abdomen, which causes the veins to swell. When the veins swell, they become irritated more easily. Pregnancy, obesity, coughing, sitting or standing for extended periods, and straining on the toilet are some causes of abdominal pressure.
