Can a bad hemorrhoid make you constipated?

Maybe the other way: Many times it is the other way; that constipation causes hemorrhoid formation or hemorrhoid irritation. Drink plenty of liquids and add fiber supplements such as Metamucil and try to avoid constipation. Eat healthy foods of fruits and vegetables, avoid fast foods and junk foods. See your doctor to see what treatment options there are for you.

Yes: yes it can - due to pain, you learn not to go for a bowel movement often, so you risk getting constipated.
