Serious illnesses may also cause the bleeding. It's best to make sure. Eat high-fiber food and drink plenty of water. Take a stool softener if your health provider recommends it. Don't use too many laxatives.
Diarrhea can also cause hemorrhoids.
Get enough exercise, which can help prevent constipation. Ask your health care provider what you should buy to help with pain and itching. Wipe gently after a bowel movement. Wipe with soft, moist toilet paper. If you need to, shower instead of wiping.
