How do you prevent hemorrhoids?

Quick Answer
Prevent hemorrhoids by keeping stools soft and avoiding pressure on the rectal veins: eat 25 to 38 grams of fiber daily, drink plenty of water, exercise regularly, and do not strain or sit on the toilet for long. Take breaks from prolonged sitting, respond to the urge to go promptly, and support vein health with fiber and, if prone to flares, a daily supplement.
Prevention targets the two mechanics behind hemorrhoids: hard stool and sustained pressure. Keep stool soft and easy to pass with adequate fiber (25 to 38 grams daily), plenty of water, and regular movement, which keeps the digestive system regular. On the toilet, do not strain, keep visits short, skip the phone, and go when you feel the urge rather than holding it.
Reduce venous pressure the rest of the day, too: break up long stretches of sitting, use a cushion if you sit for a living, avoid holding your breath and bearing down when lifting, and maintain a healthy weight. People who are prone to recurrent flares often add a daily fiber supplement and internal vein support to keep the cycle from restarting.
