There are a few things you can do help prevent the development of hemorrhoids — or at least, decrease their impact. This might includes lifestyle changes like: Avoid sitting for extended periods of time: Take breaks periodically throughout the day. For example, go for a quick walk every 1 – 2 hours. Consume a high-fiber diet: This involves fresh fruits and vegetables, whole grains, and more. If you find it difficult to eat enough fiber, a fiber dietary supplement could be something to consider. Consume plenty of water. Get regular exercise. Go to the restroom when you feel the urge, rather than waiting for another time.
