[|Human|] For the past several months, my 42 year old husband has been experiencing headaches, dizziness, light headed, weakness, fatigue, unstable blood pressure going really high or really low with no in between, night sweats, and says he s freezing a lot in the evening hours. No fever. He s had exams/blood work for diabetes, etc. along with MRI and stress test, which all report back normal. He has passed out with these symptoms. It appears to get worse each week. There s definitely something going on with him but we re not getting results from family physician or ER physicians. I truly feel he may have a blockage decreasing blood flood to the brain. Yes, he has smoked since he was 15-16 years old. Please advise.
[|AI|]  Hello! Welcome on Chat Doctor ! I understand your concern and would explain that his symptoms could be related to blood pressure fluctuations. It is important to investigate for the possible causes of these blood pressure fluctuations. For this reason, I would recommend performing some tests (if you have not performed them yet): - blood electrolytes- PCR, sedimentation rate for inflammation- thyroid hormone levels for possible thyroid dysfunction- a Head Up Tilt test for possible orthostatic hypotension. Considering the fact that he has been smoking for such a long time, I would also recommend performing a Doppler ultrasound of the carotid arteries. Hope you will find this answer helpful! Best wishes,
