[|Human|] on my way to work on the tube this morning i noticed difficulty breathing them felt sick and dizzyness, i then found it vey difficult to see properly, and was unbalanced and couldnt stand, after a while i felt absolutely fine again, what could have caused this?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. By your history and description, possibility of transient ischemic attack (TIA) is more. It is momentary decrease in blood supply to some part of brain which is causing sudden onset dizziness, not able to stand, imbalance, breathlessness etc. So better to consult neurologist and get done clinical examination of Central nervous system (CNS), blood pressure monitoring and MRI brain to rule out major CNS pathology. Also get done serum lipid profile to rule out dyslipidemia. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
