Does Low BP Cause Fainting?

I woke up last night real hot and real clammy,when I got up to go to the bathroom room to have a bowl movement I felt like I was going to pass out.The whole time i was sitting on the toilet I still felt like I was going to pass out.I got up and walk to my closet to put shorts on and then the next thing i know my husband was telling me I had passed out.I was still not really aware of what was going on.he helped me back into the bed,then I thought i was going to throw up.My siser found out 6 months ago that she has some type of low blood pressure.They put her on a table that would lean,thats how they found out what was wrong with her.Because her blood presure was always normal other when they did the lean table.Do you have any advice.Beverly

Hello, Beverly. Thank you for your question and welcome to HCM. I understand your concern.

Simply put, one faints when there is not enough oxygen supply to the brain. Since oxygen is brought on by blood circulation, then any reason that can cause lowering the amount of blood circulating to the brain, should be taken into account. It would also be helpful if, by your information, you provided your age and whether this is the first episode of fainting/near-fainting/dizziness that you experience. Nevertheless, some tests would be appropriate at this time. I would recommend you to do a complete blood count, to rule out anaemia; an EKG, to rule out any possible problem in the electrical system of the heart; an echocardiogram, to rule out the possible valvular apparatus disease as an origin of this episode; a 24-hour Holter rhythm monitor, to rule out any conduction disturbances in the heart; and an echo-Doppler examination of the carotid arteries, to rule out any obstruction in the neck arteries. More or less, my opinion is to rule out or confirm these main reasons first. Then, we can proceed to a tilt-table test. In the end, after all, a single-episode of fainting during the entire life, can happen to any healthy individual. But, I strongly recommend that the above mentioned tests should be performed.

I hope I was helpful. Take care and feel free to ask again. Good day.
