The causes of hemorrhoids are straining during bowel movements, sitting for long periods of time on the toilets, and chronic diarrhea or constipation.
Excess weight, especially in the abdomen and pelvis, may increase pressure on pelvic veins. Pregnancy [during pregnancy) increases blood flow to the pelvis and relax supportive tissues while the growing fetus causes increased pressure on blood vessels.
During labor, hemorrhoids may develop because of the intense pressure on the anal area while pushing to deliver the baby]
Medical conditions. For example, long-term heart and liver disease may cause blood to pool in the abdomen and pelvic area, enlarging the veins.
It’s also possible to inherit a tendency to develop hemorrhoids. Hemorrhoids are more likely as you get older because the tissues that support the veins in your rectum and anus can weaken and stretch with aging. The best way to prevent hemorrhoids is to keep your stools soft so that they pass out easily. To prevent hemorrhoids and reduce symptoms of hemorrhoids, follow the following health tips:
Eat high-fiber foods: Eat more fruits, vegetables and whole grains. Doing so softens the stool and increases its bulk, which will help you avoid the straining that can cause hemorrhoids or worsen symptoms from existing hemorrhoids. Add fiber to your diet slowly to avoid problems with gas.
Drink plenty of fluids: Drink six to eight glasses of water and other liquids (not alcohol) each day to help keep stools soft. Also consider fiber supplements. Most people don’t get enough of the recommended amount of fiber — 20 to 35 grams a day — in their diet. Studies have shown that over-the-counter fiber supplements, such as Metamucil and Citrucel, improve overall symptoms and bleeding from hemorrhoids. These products help keep stools soft and regular. If you use fiber supplements, be sure to drink at least eight glasses of water or other fluids every day. Otherwise, the supplements can cause constipation or make constipation worse.
