Get Enough Water
It may seem like a simple solution, but keeping hydrated eases digestion and supports muscle function. If you’re drinking enough water, then your digestive system can process nutrients and move waste out. So, how much water is enough to prevent constipation, and thus avoid anal fissures?
The rule of thumb: If you feel thirsty, then you should probably drink water. However, if you’re feeling constipated, then drink at least eight ounces every two hours. Divide your body weight in half. Now, take that number and drink the same amount of water (in ounces). So, if you weigh 150 pounds, then you should be drinking 75 ounces per day. That’s about nine cups per day.
