My father was struck down with a bout light headed ness and dizziness yesterday. Nearly to the point of being sick. He has mended a lot better today but has very bad heartburn. Would this be common or caused by an underlying problem Any help would be appreciated thanks
Is there any h/o hypertension or diabetes, is he taking any medicine on regular bases if he is not on any medication it may be simple vertigo with gastroesophageal reflux disease.  If he is hypertensive or diabetic then it might be fluctuation of blood pressure or blood sugar. So give any Proton pump Inhibitor like pantoprazole and tab vermin 8 mg twice a day if dizziness persist, and do basic blood test to rule out Diabetes. And check his blood pressure and ECG to rule out any cardiac problem.
