Question: My 12 yr. old daughter has been having frequent hiccups for about 1-1/2 yrs. She has been to 2 PA's, a pediatrician, a cardiologist and no one has an answer. They have tested her blood sugar & some other blood tests. She's had EKG's & ultrasounds.It seems like the hiccups start shortly after she eats & she gets up. I'm starting to give up hope to find an answer. She's even had friends that make comments about her having the hiccups so much. It's really bothersome for her & starting to get annoying to others. Would could be the problem?

She has the hiccups everyday & we've kept track of the different foods she eats & haven't found any types of food make any difference. She also gets them sometimes when she hasn't eaten. She can sometimes have hiccups about 10 times a day. She at times has felt dizzy, felt hot, sometimes red cheeks, sometimes pale, headaches. She's also had several recurring episodes of feeling sick to her stomach & has vomited. There has been times that she's even woke up during the night & felt sick, vomited & sometimes even just laid on the bathroom floor. She's missed the most school days of her school yrs. the last 1-1/2 yrs. She used to have perfect attendance. The teachers have even asked her sometimes if she feels OK & have sent her to go lay down for awhile. This summer since school's been out she hasn't complained as often of feeling sick, but the hiccups still continue.
The cardiologist tested her for neuro-synco but didn't diagnose that to be the problem. He put her on Famotidine for 1 mo. but that didn't help,actuallly sometimes she felt worse.The cardiologist suggested she maybe should be seen by a gastronolergist & have a scope done, possible a biopsy. Do you think this would be needed? I don't want her to encounter those tests if there would be any way else to figure out what could be wrong. I just would like to get her better & feel assured there isn't something medically seriously wring with her.
