WHAT IS SYNCOPE?
Syncope refers to a condition in which a person temporarily loses consciousness. Syncope may also be called fainting or passing out. It is caused by a sudden decrease in blood flow to the brain. This can happen for a variety of reasons.
Most causes of syncope are not dangerous. It can be triggered by things such as needle sticks, seeing blood, pain, or intense emotion. However, syncope can also be a sign of a serious medical problem, such as a heart abnormality. Other causes may include dehydration, migraine headaches, or taking medication that lowers blood pressure.
Your health care provider will do tests to find the reason why you are having syncope. Talk with your health care provider about your symptoms. Stay well hydrated and avoid prolonged standing.
Always get help if you faint, hit your head or are injured, if you have irregular heartbeats, chest pain, or shortness of breath, have a seizure, severe headaches, vision problems, or trouble walking. These symptoms may represent a serious problem that is an emergency. Get medical help right away.
