CanGERD be dangerous? On PPI. Currently having trouble breathing/swallowing while I sleep even propped up. I can deal if I know I'm not in real danger

GERD. GERD is not life threatening but can lead to esophageal damage, stricture or malignancy, cough, aspiration,wheezing or hoarseness. A gastroenterologist is best qualified to evaluate, treat and advise you. When sleeping make sure that your chest is higher than your abdomen to minimize nocturnal symptoms.
