There are steps you can take to help prevent hemorrhoids or, at the very least, reduce their effect. This often involves lifestyle modifications, such as: Staying well-hydrated: Everyone should consume at least 6 – 8 glasses of water per day. Eating foods high in fiber: Fresh fruits, vegetables, and whole grains tend to be high in fiber. A fiber supplement may be ideal if you struggle to get fiber into your diet. Using the restroom upon having the urge rather than waiting until later. Avoid sitting for extended periods of time: It is important to move around throughout the day, such as taking a short walk every 1 – 2 hours. Getting regular exercise.
