My gastric emptying study showed I retained only 15% after 3 hours and was empty at 4 hours. I have had GERD for five yrs. I have chest pain in my sternum. I have one dr saying gastroparesis and 2 saying severe GERD. I do great until about 5 pm when I have a wave of nausea. Lost my appetite! I’m eating bland and no caffeine. It feels like a heart attack. I just try to calm down. God bless you-are you on meds?
