Dizziness: causes

Why do some patients experience sharp dizziness? The causes of this pathological condition will be listed below. Also you will learn about how you can diagnose and get rid of this unpleasant phenomenon.

basic information

What is a sharp dizziness (the reasons for this state can be associated with various factors)? In medical practice this term is used to refer to an illusory sense of the movement of oneself or surrounding things. Today a huge number of people complain about this state. Experts argue that the cause of this phenomenon can act completely different diseases. Although in most cases it is impossible to determine why a person is dizzy, it is impossible.

The mechanism of violation

Why develop sharp dizziness, weakness? The reasons for this condition should be identified only by an experienced doctor.

A healthy person keeps balance by combining the signals coming from the proprioceptive, visual and vestibular systems into the cerebral cortex. After this, the impulses reach the eye and skeletal muscles, as a result of which the eyeballs take the desired position, and the patient's posture becomes stable.

If, for one reason or another, the inflow of impulses from the vestibular part into the cortex of the parietal and temporal lobe is disturbed, then an illusory perception of the movement of one's body or of surrounding objects arises.

Very often the concept of "dizziness" is treated by patients incorrectly. The state of faintness, a feeling of emptiness, the approach of deprivation of consciousness, and also a special lightness in the head are perceived by some people as dizziness. However, these signs of an approaching syncope, which are combined with such vegetative disorders as a strong palpitation, pale skin, nausea, hyperhidrosis and clouding in the eyes, often indicate cardiovascular pathologies, hypoglycemia, orthostatic hypotension, anemia or near-sightedness of a high degree.

Also, some people under the notion of "dizziness" mean imbalance, that is, a wobbling while walking or instability. Such disorders are very often observed after organic damage to the NS and are not dizziness.

Who to contact

What kind of specialist should be treated if the patient occasionally has a sharp dizziness? The causes of such a pathological condition can be associated with the development of various diseases. Therefore, with such a symptom, you should contact the following doctors: a neurologist, an otolaryngologist or a therapist.

Main reasons

Why there is a sharp dizziness? The reasons for men and women almost always coincide.

Experts argue that most often dizziness occurs due to damage to the inner ear or any abnormalities in the vestibular apparatus. In this case, they speak of peripheral pathology. Usually it develops against the background of infectious or viral diseases, brain trauma, nerve tumor, autoimmune diseases.

If the symptom in question was triggered by a pathology in the brain, then in this case they speak of a central kind of dizziness. Such signs can arise because of the following diseases: traumatic brain injury, multiple sclerosis, migraine, circulatory problems in the brain, encephalitis.

So why is there a sharp dizziness? Causes in women and men are most often associated with problems of one of the three main systems of the human body:

• Visual;
• Vestibular;
• Muscular.

They are responsible for the movement of the body in space. If such a symptom is accompanied by nausea or weakness, then it speaks of cerebral diseases or problems with the optic nerve.

Diseases that cause dizziness

Why does dizziness develop? The causes of this condition are very often associated with the presence of certain diseases. Identify them should only a qualified specialist. For this, the doctor should carefully examine and interview the patient, and also assign him a series of tests.

So, what causes the sudden dizziness and loss of consciousness? The main diseases causing this condition will be considered right now.

Inflammatory process in the inner ear

Dizziness, provoked by such a disease, is accompanied by secretions from the ears bloody and purulent. Also the person very badly hears.

In the event that tinnitus appears only on one side and the patient is disturbed by vomiting, drowsiness and nausea, this indicates the presence of perilymphatic fistula. With this diagnosis, you should undergo a complete examination, and also be convinced of the absence of a brain tumor.

Meniere's syndrome

Why there is sharp dizziness, vomiting? The causes of this condition can be concealed in various diseases. Often this symptom occurs with Meniere's syndrome. It is also accompanied by nausea and hearing problems. Very often such a disease develops during adolescence. It is dangerous because it can lead to the formation of neuritis. By the way, vestibular neuritis also causes a sharp dizziness, especially after lifting the person from the bed and during the movement of the head. With this pathology, vomiting often occurs, which can disturb a patient for up to two days.

Stroke

What can be associated with a combination of such unpleasant symptoms as sudden dizziness and nausea? The causes of this phenomenon can hide in serious pathological conditions like a stroke. Such a disorder causes an acute dizziness and headache in a person, which is undulating. Also, the patient may be disturbed by severe vomiting, after which a state of drowsiness and weakness develops. Often when a stroke a person is poorly oriented in space. This condition can last for several days.

Pinching of the nerve

Pinching of the nerve in the cervical spine causes not only dizziness, but also a severe headache. In this case, pain begins to disturb the patient when he moves his head. There is also stiffness in the neck.

Other reasons

In addition to all the listed diseases, dizziness can arise due to a craniocerebral injury, a cold and after a concussion. Also, the head can get sore and spin with a migraine of the vestibular nature. This state usually lasts not for long (from one minute to several hours). This may cause other neurological symptoms.

Dizziness very often occurs in women and men who have problems with the vestibular apparatus. At the same time they are often disturbed by drowsiness and nausea. As a rule, it is very difficult for such people to travel in transport.

This symptom may appear due to the use of certain medications, including antibiotic medications. In this regard, it is very important to pay attention to the dose taken or completely cancel the drug.

In the fairer sex, dizziness is often psychogenic. At the same time, they constantly feel drowsy and panic. The latter is unexpected, especially if a person is in a crowded place or a closed space.

Causes in men

Vertigo in the stronger sex can arise because of:

• Drinking or drinking a lot of alcohol.
• Intoxication or poisoning with various substances.
• Sharp jumps of blood pressure.
• Tumors of the brain.
• Because of diseases of the vegetative-vascular system, heart attack or stroke.
• Strong fatigue, lack of sleep and stress.
• Hopping, moving, increased physical exertion, climate change.
• Fear of heights.

Dizziness when standing up sharply: causes

Many people complain of dizziness that occurs when they abruptly change their position of the body or get out of bed. If such a state occurs rarely, then you should not worry. But when this happens every day, you should definitely take urgent measures. After all, this phenomenon can be indicative of a disease such as orthostatic collapse.

What causes dizziness when you get up

The reason for dizziness in sudden movements and getting up is due to the fact that the brain lacks O ₂ . If a person continues to move rhythmically, he may lose consciousness.

Experts call this a state of vertigo. It occurs due to various causes, including due to abnormalities in the vestibular apparatus, neuritis, inflammatory processes in the ears, neuronitis, stroke and trauma. Also, people who have heart and vascular disease suffer from dizziness when they get up.

In adolescence, this phenomenon occurs due to puberty.

One can not help saying that such a state as a vertigo is characteristic of inactive people leading a sedentary lifestyle. This is why patients with this symptom are advised to move more, and also perform special gymnastics, which positively affects the vestibular apparatus.

Diagnosis, treatment

Sure, dizziness brings tremendous discomfort to the patient. Therefore, when observing this symptom, you should always contact an experienced specialist. The latter will identify the cause of the development of this phenomenon and prescribe the appropriate treatment.

It should be especially noted that dizziness in itself is not a disease. This is just a secondary symptom of this or that disease. For its detection, the patient can be sent to MRI, ultrasound of cerebral vessels, computed tomography and so on. Also the patient is sent for the delivery of general and special tests.

As it was said above, in such a condition as dizziness, the patient very often goes to the neurologist. However, with the same problem, it can be observed in an endocrinologist or cardiologist.

Attacks of dizziness, vomiting, weakness or nausea can go away on their own. If such conditions are associated with the presence of serious diseases, then their intensity is reduced by the course of taking certain medications.
