Hi, my wife (43) has have severe nocturnal pains in her stomach accompanied by excessive burping, and flatulence. Her prior medical history includes 2 C-Sections and one surgery to remove gall bladder (stones).For this particular problem, she has gone through two endoscopies, a colonoscopy and an ultrasound by her GI. The GI stated that she saw nothing of concern there, but put her on Prilosec once a day. It was fine for a few months then it came back. Dosage was upped to twice a day (morning and night, before food). Again, the pain went away and came back in a few months. Switched to Dexilant (sp?). The pain went away and now its back. Doc added Ranitidine before bed time, but it seems to help only occassionally.She eats her meals a full 4 hours before bedtime and doesn't snack after that. But still the pain comes back randomly, for a few days at a time. This time though, the pain has lingered on for a week, but only at bedtime. Any suggestions?
