What are the most common causes of syncopes?

Syncope is more often known as fainting, and the causes of syncopes usually include lack of blood flow to the brain. This may happen for a number of reasons that ultimately result in the deprivation of oxygen in the brain, usually temporary. There may be a problem in the function of the heart, blood vessels, or some of them caused by a sudden emotional response to the environment or environmental stimulus.

One of the most common root causes of syncope is low blood pressure. This occurs when the heart draws less than the required amount of blood through the body, resulting in lower amounts of oxygen into the brain. Irregular heart rhythm, palpitations or other cardiac conditions may contribute to this risk. If this deprivation of oxygen occurs, it can be sufficiently serious to cause fainting and loss of consciousness.

hypotension or low blood pressure is often caused by sudden changes in the rhythm of the individual's heart. This may occur there is a major emotional reaction to something in the environment, sudden physical threat orthe effort or suddenly involuntary function of the body. Heavy and prolonged cough can lead to a drop in blood pressure and lead to an experience called Synopa; This applies to the causes of syncopes that include a sudden occurrence.

Stress is one of the most common and best known causes of syncopes. Bad news, pressure at home or at work, or a sudden event that changes life, can all play with the heart rhythm and lead to fluctuating blood flow to the brain. The predecessors of the loss of consciousness can feel deleted and dizziness in these situations. Sycopa caused by these types of emotional stimuli is called vasovagal syncope.

Another of the common causes of Synkopa is dehydration. There is no properly hydration during exercise can cause the heart to work and pump less blood through the body and to the brain. Maintaining hydrated can eliminate most of the problems, and if not, fainting can be a sign of more serious condition during exercise. Excessive sweating to get rid ofis the body of vital water that should be replaced when participating in severe physical activity.

Sometimes, it simply moves quickly, can cause a change in the way blood is taken to the brain. Suddenly, especially when it is associated with other conditions such as dehydration or fatigue, it can lead to syncope. When it is stationary for a long time, for example, in a long flight, it is important to get up and stretch occasionally and be careful. Most often it is associated with a certain pressure on the neck artery of the neck, which limits blood flow to the brain.
