There is no known direct genetic or hereditary risk for hemorrhoids. They form from increased rectal pressures related to constipation and difficult defecation, which are extremely common in our environment of low fiber diets. So, if your family tends to have more constipation and straining with stools, then more hemorrhoids will arise.

It's not a familial issue.

Some studies have indicated that your family history can predispose one to have hemorrhoids. Hemorrhoids are swollen veins in the lower part of the anus. Hemorrhoids can be caused by pregnancy, diarrhea, constipation, heavy lifting, obesity and straining. The best method for prevention is avoidance of straining with bowel movements, eating foods rich in fiber such as fruits and vegetables as well as whole grains, exercise, maintaining a healthy weight and not waiting to heed the call of a bowel movement.

Yes, that’s possible.

Yes they can run in families but they are also aggravated by other factors like constipation.
