<s>[INST] I am 57 and in good health. Today I had an episode where I felt like I was going to faint and throw up and I was really dizzy. I run 2 times a week and am about 15 pounds overweight. I was also sweating profusely. I was having lunch with a couple friends. And suddenly didn t feel well. It came on fast. Then after about 20 minutes or so I felt better. I never actually fainted. [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Regarding your concern, I would explain that your symptoms could be related to an inner ear disorder or a possible TIA (transient ischemic attack). For this reason, I recommend consulting with your attending physician for a physical exam and some tests: -a resting ECG and a cardiac ultrasound - a Doppler ultrasound of the carotid arteries for possible narrowing - blood electrolytes - complete blood count. Consulting with an ENT specialist may be needed if all the above tests result normal. I would also recommend performing a brain MRI, just to be sure that everything is OK. Hope you will find this answer helpful! Wishing all the best, Dr. Iliri </s>
