What is dizziness, know everything. This is a strange and unpleasant sensation formed the basis of the Thriller Alfred Hitchcock. However, the cinema is one thing and life is another...Dizziness is not a disease, and all but one of its symptoms - symptoms, something like a headache or high temperatures. And that's a symptom of what illness is dizziness in this particular case - it's up to doctors. However, something useful to know, and patients.
False alarm
If I felt dizzy in the arms of a loved one, during a speech before a large audience or in the process of separation, arranged formidable head - don't worry. With Your health and cause of vertigo is the release of adrenaline, which causes spasm of smooth muscle, including vascular smooth muscle, causing temporarily worsens blood supply to the brain.
In the first week of stay in orbit, the astronauts, as a rule, suffer from severe vertigo. The body adapts to weightlessness, there is a redistribution of blood, and the vestibular apparatus "going crazy" trying to determine where the top from the bottom.
Often dizziness accompanied by sickness, on the carousel and in the cinema when the film was made in the technique of "hand Luggage". Blame the discrepancy between what is perceived by our vestibular system, and the fact that we see. The brain simultaneously analyzes both the signal and there is confusion, which is accompanied by unpleasant sensations. This condition, if it is associated with water transport, called "sea sickness". For some people it is expressed more and others less. By the way, one of the most famous victims was the legendary Admiral Nelson.
If my head was dizzy from the height - not too scary. Just look into the distance, eyes hard to focus on near objects.
Even the head can be turned from the failure of the blood supply to parts of the brain responsible for balance. You don't have to hurt you, say, have failed to tip or rotate the head (be careful when doing exercises for the muscles of the neck! ). And if you forget to eat (Hello, dieters! ), the head can swirl due to the lack of glucose in the blood.
Time to treatment
If dizzy systematically, we are talking about is not about physiological, and pathological vertigo. That is, it is a symptom of some disease. But what you can guess from the accompanying sensations.
Dizziness... and only
A fairly common cause of vertigo is vestibular disease (he is in the inner ear). This dizziness is called the true or vertigo. It appears sharply, accompanied by the illusion of movement in space of one's own body or surrounding objects, as well as nausea, vomiting, cold sweat. To occur these troubles can against the backdrop of such frequent diseases like otitis then dizziness preceded by pain in the ear.
Dizziness hearing loss
If dizziness occurs in bouts that last several hours and are accompanied by noise or whistling in the ears and hearing loss - likely it is Meniere's disease. It occurs when the fluid around the auditory and vestibular part of the inner ear becomes more normal, or it changes the ratio of electrolytes. Interestingly, this disease hearing reduction can fall out certain frequencies - for example, people perfectly hear what's being said in a whisper, but cannot distinguish between ordinary speech.
If dizziness begins quietly, as if gradually, and is accompanied by unilateral hearing loss it is necessary to exclude a brain tumour. If sharply unilateral deafness occurs sharply - diagnosis is not so frightening: perilymphatic fistula. Simply put, rupture of membranes between the middle and inner ear. Distinctive feature: when coughing or sneezing, dizziness intensified.
Dizziness headache
Tinnitus in combination with nausea and dizziness, light and zvukovuyu can be a precursor to a migraine.
If dizziness and headaches are felt at the same time, it is possible that its cause is poisoning (e.g., alcohol or intoxication with severe infectious disease) or traumatic brain injury.

Vertigo suffered by such famous people as Julius Caesar, Martin Luther king, Edgar Allan PoE.
People are believed to cause dizziness can prolonged near aspen - it "pulls" energy.
Slow dizziness, which increases when moving, especially if the person at the time of its occurrence twisted head (flexion, extension, rotation, neck), most likely associated with osteochondrosis of the cervical spine.
If dizziness occurs when the change of body position and only at a certain position of the head (usually the attack lasts from several seconds to several minutes and is held at rest) can be suspected benign positional vertigo. The essence of the disease is the destruction of certain receptors of the vestibular apparatus with the release of calcium carbonate crystals. Their migration and causes dizziness.
Dizzy after taking drugs
"Turn your head may be taking certain medications: funds from allergies (suprastin, diphenhydramine), cold (Coldrex, Theraflu), some antibiotics, hypnotics and tranquilizers.
What to do?
If suddenly dizzy, the main thing is to calm down and try not to fall off when dizzy very often disturbed the balance. Sit down, and it is best to lie down so that his head and shoulders were on the same level - this provision improves blood flow to the brain. Do not make sudden movements.
