What Causes Faintness and Dizziness When Standing Up? ------------------------------------------------------------------------------ QUESTION: If I make a sudden move to stand after sitting for a spell, I sometimes get faint and dizzy and half to sit back down again. It is a bit frightening, and I wonder if you might have some idea as to the cause of this problem. Would you please explain it to me? ------------------------------------------------------------------------------ ANSWER: If you feel faint upon rising (including rising from bed in the morning), you might be suffering from low blood pressure. Now, low blood pressure has it varieties; "episodic" low blood pressure, which is linked to irregular heart rhythms that may come and go. In some cases, young, healthy people frequently have chronic low blood pressure without other disease symptoms being present. But the special brand associated with blood pressure that decreases immediately and rapidly upon rising and is often accompanied by dizziness and faintness is called "orthostatic" hypotension. This unwieldy term is used to describe a type of low blood pressure that, while not a disease state in itself, reflects the inability of the body to control pressures properly. A common reversible situation is a poor circulatory pattern, where blood pools in capillaries, thereby reducing the amount of blood the heart pumps out. It may be caused by some medications you are already taking. This is a situation that should be discussed with you physician, for there are a number of reasons, and many of them can be controlled, reducing the frequency of your symptoms. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
