How is often giddy faint to return a responsibility?

summary

Syncope is a common clinical manifestation, which brings great harm to patients. It is often manifested as visual rotation, self rotation, floating feeling, and sometimes accompanied by disgust, vomiting, sweating, blood pressure instability and other manifestations. So let's talk about how often dizzy and faint?.

How is often giddy faint to return a responsibility?

First: we normal people present syncope, most of them are caused by the change of posture. For example, after swing, turn, take the elevator, take the car wave prone to syncope. Why do postural changes cause syncope? This is related to the vestibular system in our inner ear. Along our external auditory canal inward, through the middle ear, to the inner ear, you will see the exquisite vestibular structure of the inner ear. The inner ear is like a coordinate system, with the semicircular canal of the inner ear and the ellipsoid sac. It can feel different head position changes, covering all directions of the space. When the vestibule of our inner ear feels the influence of postural changes, it passes through the vestibular nerve to the brain. The brain receives the neural induction and analysis to distinguish the facial position. The lymphatic fluid of vestibular system of inner ear has inertia. When the head position is changed violently, because of the inertia of lymphatic fluid, when the excitation of afferent nerve is inconsistent with the practical head position, it will show the performance of syncope.

Second: but in practical life, some people show syncope performance is too intense, more than the normal human body response. For example, in the absence of head position change incentives presented severe dizziness. What are the elements? It's not hard to come to a conclusion after an analysis. Syncope is a brain sensation about afferent influences. All the factors that affect each link of syncope reflex arc can cause syncope. For example, visual factors such as nystagmus, otogenic factors, lack of blood supply to the brain, intracranial tumors, nerve compression and other chaotic factors can cause syncope.

Third: about young and middle-aged people with syncope, otogenic factors account for a large proportion. Among them, otolith and Meniere's disease accounted for a large part. Otolith causes syncope. A small stone in the inner ear falls into the semicircular canal, causing syncope and even aversion to vomiting. It is very strange that it can be treated immediately. Meniere's disease is related to the imbalance of inner ear lymphatic reflux. The clinical manifestation is syncope. Syncope is accompanied by hearing loss, and then it alleviates itself. But similar performance will be repeated.

matters needing attention

Syncope is a common and frequently encountered disease. It affects many subjects. Syncope is the clinical manifestation. It occupies the number 2~3 of the outpatient complaints. The incidence rate of syncope is about 5%, and 28% of those who have had syncope in their lives. Therefore, accurate identification of syncope factors, accurate treatment, because of treatment, syncope treatment will be more useful.
