Welcome to health care magic!
I have gone through your problem and from that it is evident that you are having diarrhoea, vomiting, headaches and
dizziness, increased eosinophils. Your doctor feels it is because of
acid reflux.
I cannot say why your doctor thought that it is due to acid reflux, but from my experience I can say that it is due to some intestinal infection, may be due to parasitic infestation also.
I feel it is an infective diarrhoea as you have all symptoms similar to this. Due to frequent diarrhoea and vomiting, you have headache and weakness now.
I think that you will get good relief with some broad spectrum antibiotic, like
cefpodoxime, in a dose of 200mg twice a day along with a course of
ornidazole, and antacids cover.
Do continue to eat something , and take plenty of water /ORS to prevent
dehydration. I'm sure this is more than acid and definitely needs antibiotics.
It is common condition and can be completely cured, provided one takes proper medicine.
I hope that answer helps you.
Feel free to ask more questions
