In this study, we will recruit cirrhotic patients who are undergoing endocscopic procedures as part of their standard of care. Their endoscopies will reveal whether they have portal hypertensive gastropathy. After the procedure, we will ask the patients to provide us with a stool sample, which we will assess for occult GI bleeding. For those patients who DO NOT have occult GI bleeding, they will be contacted every 6 months for 2 years to check whether they have developed GI bleeding.
