Fainting: How Serious Is It?
Whether you call it passing out or having “a spell,” fainting is an unexpected scare that will happen to nearly one in three people at least once in their life. Although it’s common and people usually regain their consciousness quickly with no more damage than feeling a little disoriented and shaken up, fainting can be a sign of a more serious health condition.
So, what causes a person to faint? When there’s a sudden drop in blood pressure – say from standing up too quickly after lying down, being dehydrated or taking certain medications (e.g., blood pressure, depression, allergies) – blood flow to the brain is decreased.
