My eight year old daughter who has a gluten/wheat sensitivity where she is extremely fatigued and her body aches all over the next day after eating wheat or gluten.  SHe has been on the GF diet for about 6 months and has improved considerably.  For the last two months, she has complained of nausea and burping a lot.  Feels worse at night so we propped her pillow up and began giving her prevacid with her claritin every night before bedtime.  She says it is helping but still not right.  She says she also feels nausea after eating watermelon which I find strange.  Should she continue the prevacid or increase her dose?  Does this sound like GERD?
Welcome to the ChatDoctorI completely understand your concerns but don't worry. I would recommend you to go for proper line of investigation to check whether your child is suffering from celiac disease(gluten sensitivity) or not. This includes Tissue transglutaminase antibodies and duodenal biopsy if not done earlier. A gastroenterologist will help you with all this. It's very unlikely to be allergic to watermelon. The problem seems to be more of HERD or peptic ulcer disease. Lower esophageal pH measurement and H pylori test can be done to confirm this. Till then, you need to keep her head end of the bed propped up instead of added pillow and continue with prevail. Hopefully this will help you. For further questions, you may contact me. Take care
