What Causes Fainting
Syncope is the correct medical term for fainting. Those who suffer from it may not necessarily loss consciousness for a time because for some, fainting can be an altered state of consciousness. Fainting may cause you to feel light-headed, lose footing and fall to the ground. But in a brief period of time, the individual who fainted will recover spontaneously. There are those who feel a looming fainting sensation before they fall back and lose consciousness.
Syncope is one of the primary symptoms of various cardiovascular diseases, apart from non-cardio disorders and conditions. People who suffer from rapid heart rate or tachycardia, atrial fibrillation, and occasional premature ventricular contractions sometimes experience fainting. If you don’t have a cardiac problem but you faint at extreme stress or fright, you may have a vasovagal attack. It’s a condition that’s caused by vasovagal depression of the vagal nerve.
Orthostatic hypotension is another common cause of fainting. This condition happens when a person’s blood pressure suddenly drops when he abruptly stands up or changes position. Even turning to the other side when lying down can trigger orthostatic hypotension for susceptible individuals.
Epilepsy is a congenital factor that also causes fainting for some people. Epileptics may experience giddiness, cold sweat, nausea, vertigo, and they’d feel as if the room around them is spinning. Vision eventually dims before they lose consciousness.
Vertigo on the other hand is caused by impaired balance mechanisms in the ear. Those who experience otitis media or viral infection in the middle ear can cause this disorder. It is very uncomfortable and there are individuals who even experience a ringing sensation in the affected ear known as tinnitus. Antibiotics and ear drops can remedy the problem and get rid of infection and vertigo in as little as one week.
Note to bystanders and passersby, if you see someone who just fainted or is about to faint, try not to force the person to sit up or stand. Bending over gently can help, or place the head in between the legs in order to restore back proper blood circulation.
