The nervous system in our body is divided into 2 groups – somatic and autonomic. The somatic nerves mediate voluntary movement (motion, touch), while the autonomic is divided into sympathetic and parasympathetic nervous systems that have different function. The sympathetic nervous system activates in cases of emergencies, while the parasympathetic system gets activated when the body is in a relaxed state.
The vagus nerve, which is responsible for regulating the heart rate, is part of the in the parasympathetic nervous system. Today we’re going to talk about vagal syncope, a condition which occurs due to lack of coordination between the heart and brain which results in decreased blood pressure and lack of blood and oxygen to the brain. This reaction of the vagus nerve may result in numerous episodes with symptoms such as fainting that can have serious consequence on your health.
Causes of vasovagal syncope
The problem is usually caused by emotional stress, fear, severe pain and strong coughing. Some drugs, alcohol abuse, hyperventilation, low blood sugar levels and standing up from bed immediately may also cause the problem. The episodes of vasovagal syncope are usually not serious and don’t require any treatment, but if the problem occurs for a longer period it needs to be examined by a doctor.
Vasovagal syncope symptoms
People suffering from the condition have reported fatigue, chills, dizziness, tingling in the arms and loss of body control just before the fainting. Besides this, facial pallor and loss of muscle tone are also some of the symptoms of vasovagal syncope. If you notice any of these symptoms, we recommend visiting a doctor – it’s probably nothing serious, but you’ll feel much better after the tests knowing that you’re ok.
