<s>[INST] I have a friend that its 16 years old and she has been seen by every specialist available but noon of them have been able to diagnose her, the only sintom its Spontaneous dizziness along whit big amounts of saliva and a weird taste in her mouth, thanks for your help !! [/INST] Hello, I think these symptoms are highly suggestive of a possible "near syncope" with "severe gastritis". Ideally, I would need to examine her for a complete diagnosis.  However, I would like to explain it like this- 1. The weird, often bitter taste in the mouth with excess watering could be due to severe gastritis. 2. the dizziness may be a vasovagal reaction to the above which may be "near syncope". I would recommend starting with Pantoprazole tablet twice a day before meals and taking plenty of fluids. As for the tests, I would suggest testing 1. EEG2. Echocardiography and3. Upper GI Endoscopy. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor, Planetologist </s>
