There are certain things you can do to help prevent the development of hemorrhoids — or at least, reduce their effects. This can involve lifestyle modifications like: Exercise regularly. Avoid sitting for prolonged periods of time: Give yourself breaks during the day. For example, take a quick walk every 1 – 2 hours. Consume a high-fiber diet: This involves fresh fruits and veggies, a variety of whole grains, and more. If you find it difficult to consume enough fiber, a fiber dietary supplement may be ideal. Drink adequate amounts of water. Go to the restroom as soon as you have the urge, rather than waiting for another time.
