Psyllium is used to treat occasional or chronic constipation, according to the American Cancer Society. Psyllium husk seeds absorb water and expand as they travel through your digestive system, where the psyllium acts as a bulk-forming laxative. Taking psyllium supplements can also improve stomach pain and diarrhea, according to MedlinePlus 2.

Take your psyllium with at least 8 oz. of water to help the fiber pass through your esophagus safely. Psyllium can swell in your throat without ample water, causing you to choke. If you experience choking every time you take psyllium, discontinue use and talk to your doctor.
