Definition: Over-fainting is a medical condition where an individual experiences sudden loss of consciousness and falls into a state of unconsciousness. The onset of this condition can be triggered by a variety of factors, including physical injuries, drugs or alcohol, infections, and certain medical conditions such as heart failure or stroke. Symptoms may include confusion, dizziness, lightheadedness, nausea, and difficulty with speech or movement. Treatment for over-fainting typically involves managing the underlying cause to prevent further complications.
