Syncope may be a symptom of a serious disease which if left untreated may lead to permanent impairment. If you have fainted, be sure to contact your health care professional to obtain an accurate diagnosis and appropriate treatment. Syncope is not only caused by an underlying illness. Fainting occurs on very rare occasions, as a result of stretching, coughing or other situations. Vasovagal syncope accounts for about 50 percent of all episodes of fainting.
Vasovagal syncope is an unusual response to emotional stress, excitement, fatigue, hunger or pain.
Prior to fainting, you may feel lightheaded, nauseated, flushed, or warm. Your vision may dim and you may yawn. You may feel giddy. If you have any of these warning signs, lie down. If you are having a vasovagal episode, lying down will alleviate the symptoms and may prevent fainting.
