[|Human|] My Dad has high blood pressure 4 stents in his arteries around the heart including one in the y, he has cardiovascular disease and PTSD and diabetes so he takes a variety of meds. Anyway my Mom just witnessed him get dizzy and almost fall down. He says this happens sometimes but she has never seen it happen. His Bp was 116/62 when he sat back down and my mom made him check it. Isnt that low for him?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I passed carefully through your history and would explain that his blood pressure values are not too low to cause fainting or dizziness. Orthostatic hypotension could be the cause of his symptomatology. I recommend measuring his blood pressure during sitting and standing up position. If there is a decrease in his blood pressure more than 20mmHg during standing up position, compared to sitting position, this could indicate orthostatic hypotension. A Head up Tilt test is needed to rule in/out this disorder. I would also recommend performing some other tests to exclude other possible causes related to his heart: - a resting ECG and cardiac ultrasound-some blood lab tests (complete blood count, kidney and liver function tests, blood electrolytes, fasting glucose and HbA1C). If orthostatic hypotension is confirmed some modifications to his actual therapy may be needed. Hope you will find this answer helpful! Greetings!
