Light headed on workout. This problem.

It was a syncope attack.   Syncope" is the medical term for fainting. After fainting, a person quickly "comes to" and is OK again. Syncope is very common. About 1 out of every 3 people has it at some point in life. In many cases, syncope is nothing to worry about. Syncope happens when the brain temporarily doesn't get enough blood. One of the most common reasons this happens is called "vasovagal syncope." If you have vasovagal syncope, your body has a reaction in which your heart beats too slowly or your blood vessels expand (or both). This can happen for lots of different kinds of reasons. People can have vasovagal syncope if they: ●Have stress from fear or pain (for example, because they are injured or have blood taken for tests) ●Stand for too long or are over-tired or overheated ●Have an unusual reaction to urinating, coughing, or other body functions Sometimes vasovagal syncope happens with no clear cause. People can also have syncope that is not vasovagal. This can happen due to the following problems: ●The heart beats too quickly or too slowly because of problems with the heart's electrical system or because of side effects from some medicines. ●Something blocks the flow of blood in the heart. This can happen in people who have conditions called "aortic stenosis" (a valve disease) or "hypertrophic cardiomyopathy" (a heart muscle disease). ●Your blood pressure drops when you stand or sit up. That can happen if you: •Do not drink enough water •Take certain medicines that cause your blood pressure to drop •Drink alcohol •Lose a lot of blood (for example, if you get hurt) •Have a medical condition that affects your blood pressure Can syncope be prevented? — You might be able to reduce your chances of fainting again if you: ●Learn what causes your syncope: •If an activity or condition causes your syncope, you can try to avoid it. •If a medicine causes your syncope, your doctor can help you find an alternative. •If a heart condition is causing your syncope, your doctor can suggest a treatment. ●Lay down with your feet up when you feel like you might faint.
