momentary blackouts??

Question

Sometimes when i stand up, walk, or strech i kind of blackout. I'm still totally consious and all but everything goes black and i cant see anything and i get really dizzy and unstable. This happens daily probably. Usually it only lasts a few seconds and my vision fades back in. but today I stretched my arms above my head and the usual thing happened, except it lasted a lot longer than it normally and I got a lot more dizzy. I almost fell over and had to like shake my head to get out of it.

is this something serious or what??

Answer 1

You need to see the Dr. it could be your blood pressure or sugar level as diabetes, or petite seizures. I really don't think it is the seizures, I have them and I go blank and stare and can't talk or understand another for a few minutes.
I think one of the other 2 and they can be serious if yo wait.
You don't want this to happen while driving or standing on a chair and reaching for something, and other times that could be really bad.

Answer 3

It is called being orthostatic. It basically means that when you stand up, your blood pressure can not adjust. It often comes from being dehydrated. You should drink some more water and stand up slower. Being tall or being in a heated place can make this occurence worse or it can happen when you have been laying down for a long time. Sit up first and then stand. You just don't want to cause that huge difference in your blood pressure. Some people naturally do this (like me and you) and some only do it when they are stressed or not particularly well (like having the flu). Just make sure to get fluids and avoid going from laying to standing too quickly. It is not terribly dangerous.

Answer 4

My guess is that you are tall and thin, perhaps a teenager.

Your condition is probably postural hypotension, also called orthostatic hypotension. When we move from a reclining or a sitting position to a standing position, our blood pressure falls briefly, but our body's homeostatic mechanisms rapidly kick in to raise it again. It does so by adjustments to the tone of the muscular lining of the arteries, and to a lesser extent, the veins, and by increasing the stroke volume of the heart and increasing the heart rate. In some persons, these adjustments occur more slowly, so there is a brief interruption in the flow of blood to the brain, and the person gets the symptoms you described.

But the appearance of these symptoms with stretching exercises or with walking bothers me. You probably should bring these symptoms to the attention of your physician. He/she can take steps to determine whether it's common postural hypotension, rare subclavian steal syndrome, or whether it may be cardiac related. Sometimes a stress-exercise test is in order.

Answer 5

You really need to ask to see your doctor early. Anytime you have pain, dizziness and blackout, there's something wrong. See if they can get you an earlier appointment. Good luck.
