Common "Fainting" queries answered by top doctors | iCliniq


Fainting or syncope is a temporary loss of consciousness due to decreased blood supply to the brain. The sudden decrease in blood pressure leads to less blood supply to the brain. Dehydration, low blood sugar, heart disorder, medication, etc., are the cause of a sudden drop in blood pressure. Raising the level of the leg above the heart level helps in bringing back consciousness.
