Fainting

Fainting is a sudden, brief loss of consciousness and muscle tone, usually caused by a drop in blood pressure. It is often accompanied by a feeling of dizziness, lightheadedness, and confusion. Fainting usually occurs in response to a sudden emotional or physical stressor, such as standing for a long time or intense fear. Symptoms of fainting may include sweating, pale skin, blurred vision, and weakness in the arms or legs. In some cases, fainting may be the result of an underlying medical condition, such as heart disease or diabetes.
