G Poem is a procedure done endoscoply during which s “tunnel” is made by separating layers of the mucosa in the pylorus so that food empties from the stomach into the small intestine. My husband also takes an antihistamine, cyyproheptadine, which somehow enables him to eat more. The weight gain is slow , but at least he can eat larger amounts than before the procedure. The GPOEM was done at Columbia New York Presbyterian Hospital by Dr Sethi
