Feeling of dizziness, passing while going on knees. What does this indicate?

Hi, for some reason I get really dizzy and feel like I m going to pass out when I go on my knees. I kneel down, with my body in the upright position, I immediately feel it. I have to lean forward and put my hands on the floor within seconds, or I feel like I will pass out. What could this mean? I drink lot s of fluids, I exercise, my blood prressure is good. I don t understand it. Can you give me some ideas?

Hi Steve,
Thanks for writing your query.

It will be helpful if you please mention whether you are on any medicines and any history of any illness.

It seems that you are having either postuarl hypotension or vasovagal attack resulting in decreased blood flow to the brain.

You should get your blood pressure recorded in lying, sitting and standing position.
Also get yourself investigated for :-
1. Hemoglobin
2. Blood sugar
3. ECG

Also get an ENT checkup to rule out any internal ear dysfunction and a head scan to know the brain status.

Avoid immediate change in posture. Whenever you change in your posture, it should be slowly. This will not result in sudden fall in blood pressure.

Lying down with head at lower height than feet will help you in recovering soon from light headedness.

If the problem persists, get yourself examined by a Neurophysician.

I hope this is helpful to you.
