<s>[INST] Hello Doctor, Compliments of the season to you. For the last few days I have been having a few dizzy turns accompanied with hot sweats and almost fainting. The situation doesn t last more than two minutes max. I am 66 and wondered if I have some kind of inbalance Not such great timing, as my Doc is on holiday till next week. Any ideas would be welcome, many thanks. Regards John [/INST] Hello am Chat Doctor. I have read your query. I think I can help you. Unfortunately, there is no simple response to your query. The symptoms as mentioned by you in the query could be either due to a cardiac cause, or due to a neural cause or could simply be the burden and strain of the season. In such a situation, it is difficult to tell you the exact cause. You will need to get further tests done- Echocardiography, CV Doppler, EEG, blood counts and electrolytes are the tests that I would suggest to a patient I would have had a chance to examine. I recommend the same to you. I may be able to help you further if you inform me the reports.Meanwhile, watch your fluid and electrolyte intake. Often, that itself may lead to your symptoms. I have tried my best to make it as simple as possible. Please feel free to contact us for more information. Best of luck, </s>
