What causes blood pressure to rise when you get up? It is usually lowered when you stand.?
I have a seriously ill family member who is currently experiencing his blood pressure rising to dangerous levels when he gets up which causes blackouts. Does anyone know what causes a rise in blood pressure when you get up he currently just had a MRI but I would like to know where to look on the net. Most things state that your blood pressure drops when rising.
Thanks alot!
Thanks for your answer but that is why I am having problems searching for this everyone is assuming that it is low. He blackouts and his pressure is tested and it is rising drastically.

This can happen with exertion. Blood pressure changes during the day. It is lowest as you sleep and rises when you get up. It also can rise when you are excited, nervous, or active. The heart beats faster on exertion, and pumps out more blood. After lying down, the body must make an almost instant adjustment in BP to supply the brain with blood. To do this blood vessels in the abdomen and legs constrict and the heart rate goes up. If there is a delay in this happening it can cause dizziness and yes even blackouts if the delay is longer.
My guess is that this is a side-effect of the illness.
Are you sure the BP rises when he gets up? I think it may be a quick drop of BP that causes the blackout. When one gets up too quickly, the BP drops and the body can’t adjust as fast which in turn causes a blackout. What he should do is rise to a standing position slowly.
