Have had pulsating bubbling stomach for years. light headed most of time and a bit concerned now as when lie in bed at nite its at worst?

Stress-related or?: Lots of causes of "stomach pain", but epigastric burning ; pain after meals raises the probability of gastritis ; ulcers. Stop alcohol, tobacco, non-prescribed nsaid's ; start an otc acid reducer (like Prilosec otc, Prevacid (lansoprazole) 24hr). Please get checked with lightheadedness, esp. If, worsening symptoms, vomiting coffee ground material or passing black stool or blood. Could stress be contributory?
