[|Human|] I m a 71 year old mail, very healthy. twice in the last 6 weeks I ve felt very lightheaded. fainted once and broke a chair. Second slumped to the floor and crawled to a rug where I rested for a minute or two before climbing up on a couch. After @ 20 minutes I got up, feeling fine, rest of the day has been fine. I ve worked without incident.
[|AI|]  Hello! Welcome on Chat Doctor ! Your symptoms could be related to different possible causes (low blood pressure, orthostatic hypotension, a cardiac arrhythmia, chronic degeneration of the cervical spine, vertebro-basilar insufficiency, etc.). For this reason, I would recommend consulting with your GP for a careful physical exam and performing some tests: - a resting ECG and cardiac ultrasound-complete blood count for anemia-blood electrolytes- kidney and liver function tests-fasting glucose- an EEG - an ECG Holder monitoring- a Head up Tilt test for possible orthostatic hypotension. Meanwhile, I recommend you to monitor your blood pressure values and take plenty of water. You should discuss with your doctor on the above issues. Hope you will find this answer helpful! I remain at your disposal for any further questions. Kind regards,
