Causes of syncope in children

Many people have experienced dizziness after standing up suddenly after sitting for a long time, especially children. They sit on the ground for an hour or two every time they play, and then stand up suddenly, which leads to insufficient blood supply to the brain and fainting. In this case, you need to go to the hospital for examination as soon as possible to avoid recurring. This article introduces the symptoms before syncope in children and the common types of syncope. If you are troubled by this, you should definitely take a look at it.

Before the onset of the disease, children first feel general discomfort, blurred vision, pale face, sweating, then dizziness, limbs become weak, and suddenly lose consciousness.

Common types of syncope are:

1. Reflex syncope. The most common type of syncope, accounting for about 90% of all types of syncope. It can also be divided into simple syncope and postural hypotension.

Simple syncope often has obvious triggers, such as emotional tension, fear, stuffiness, standing for too long; or it may be caused by various punctures, injections, tooth extractions, etc.

Postural hypotension occurs when you stand up suddenly from a lying or squatting position, or when you stand for too long. Certain drugs such as doxepin and levodopa can cause orthostatic hypotension.

2. Cardiac syncope. Such as severe arrhythmia, sick sinus syndrome, cyanotic congenital heart disease, primary pulmonary hypertension, etc.

3. Cerebral syncope. Transient cerebral ischemia, pulselessness, subarachnoid hemorrhage, chronic lead poisoning encephalopathy, etc.

4. Medullary syncope. Vascular lesions of the brainstem, tumors, degenerative diseases of the central nervous system, high-level poliomyelitis, etc.; certain drugs such as tranquilizers and sedatives have a direct inhibitory effect on the vasomotor center.

I hope this will be helpful to parents and friends. No matter what the disease is, no matter how serious it is, as long as you understand the cause and pathology, you will be able to achieve twice the result with half the effort. With regular treatment, you will soon be free from the pain of illness. At the same time, I wish all children good health and happiness.
