This phenomenon is very common among younger people aged 15-30, and especially women. Losing consciousness can lead to a traumatic fall or even a fatal accident, like while driving a car. This is known as syncope – or fainting.Īlthough vasovagal syncope in itself is harmless, it’s really the circumstances in which it occurs that can make it dangerous. The drop in blood pressure causes the blood flow to our brain to lower, and this can make us feel temporarily unwell, or experience a brief loss of consciousness. It is involved in the regulation of our breathing, digestive system, blood pressure and heart rate. The vagus nerve plays an important role in the healthy functioning of the body. This is the result of hyperstimulation of the vagus nerve, hence the term ‘vasovagal episode’. Vasovagal syncope is caused by a sudden and temporary drop in your blood pressure and heart rate. Most of the time it’s not a serious condition but it’s important to monitor it, especially if you experience regular fainting. It can affect a lot of people and has many different symptoms.
Vasovagal syncope is the medical term for fainting caused by not enough blood reaching the brain.
