Drinking sufficient of water is a good, natural way to treat minor internal hemorrhoids and painless external hemorrhoids. Water is essential because it provides the colon with enough moisture to keep your stools from drying out. Water makes the stool softer which decreases constipation and straining. This will help the inflamed veins to shrink in size.
How much water you need to drink depends on how active you are. If your work involves physical activity you may have to drink more than someone who is sedentary. The average person should drink about 8 glasses of water a day. But each person is different and you should pay close attention to how the amount of water you drink affects your bowl movements and stool softness.
If you are constipated you can try eating some dried prunes or drinking prune juice. Prunes have a mild laxative effect that will make your bowel movements easier, reducing straining.
