My 20-yr old daughter has been experiencing daily nausea for about 6 weeks, since she got back from Mexico. So far, we have done an ultrasound, endoscope, colonoscopy, and a biliary scan only to find that she has irritation caused by GERD and Barrett s esophogus caused by the continued irritation. She is loaded full of medications for both the acid reflux and nausea, but nothing is helping. She is losing weight from not being able to eat, cannot sleep, cannot work. What else can we do?
