<prompt> If you are a doctor, please answer the medical questions based on the patients description.I been experience bad breath for the past 6 months. I have gone to a dentist who put me on breath rx products, doesnt work. I brush and floss twice a day. I have also experience violent vomiting spells at least twice a month for the last six months also. I burp and I always feel like my food is coming up all the time. please help.  <response>: Hello thanks for the consult at Chat Doctor, u might be having bad breath due to systemic causes, since the usual mouth rinse and other stuffs hasnt helped u,all ways do salt water gargle thrice daily, with ho of severe vomiting and burping u might be having increased gastric reflux, kindly consult a gastroenterologist for a check-up and investigation, and then your periodontist, hope it helps, TC
