The easiest way to reduce the risk of hemorrhoids is to have an active lifestyle. Obesity and a sedentary lifestyle can cause them to develop. Eating a high fiber diet can also keep them at bay. Consuming unprocessed carbohydrates such as fruit or cereal can soften and bulk up the stools for easier bowel movements.

Other common causes include:

  • Sitting for a long time
  • Straining through a bowel movement
  • Chronic constipation or diarrhea
  • Pregnancy
  • Aging
  • In some cases they may be caused by other diseases, such as liver cirrhosis.
