Why dizzy and nauseous?

Dizzy and nauseous - this is a clear violation of the equilibrium system, which includes the brain, sensory organs - vision and hearing, the vestibular system, the peripheral circulatory system, and the nerve endings of the whole organism. The regulator and the main "controller" of equilibrium is the brain, which systematically receives signals from distant organs. With any changes in the signal system or with the pathologies of the “controller” itself - the brain, the system begins to fail. The initial symptoms may be unusual weakness, dizziness, nausea as an inevitable sign of loss of control from the brain. The loss of balance is called vertigo - a symptom that has its own gradations, corresponding to the localization process.

Causes of the dizziness and nausea

Central vertigo, vertigo. 

• Osteochondrosis of the cervical spine provokes a violation of blood circulation, including in the brain, where the balance control center is located. 
• Migraine, seizures of which are inevitably accompanied by dizziness and nausea. 
• Brain tumors. 
• Epilepsy, which, regardless of type and severity, is accompanied by vertigo and nausea. 
• Circulatory disorders of the brain - meningoencephalitis, encephalitis, Lyme disease. 

Peripheral vertigo, vertigo. 

• Meniere's disease - a pathological increase in fluid in the cavity of the inner ear. 
• Traumatic ear damage. 
• Vestibular neuritis, neuronitis - impaired blood circulation in the vestibular apparatus.

If dizziness has central localization and typical autonomic disturbances - weak nausea, vertigo passes, usually independently.

Peripheral vertigo is more severe in symptoms, as it is accompanied by severe arrhythmia, nausea is often accompanied by vomiting and weakness.

Vertigo can also be provoked by chronic hypotension, more precisely, orthostatic hypotension. Collapse syndrome, characteristic of this condition, occurs with a sharp change in body position. For example, with a quick change of posture or when bending, getting out of bed. The change of the horizontal position to the vertical in hypotensive patients often causes typical signs of vertigo when dizzy and nauseous. 

Hypoglycemia or fasting at the level of digestion, lowering blood sugar levels. Lack of glucose dramatically reduces the ability of the brain to control equilibria, as a result - dizzy and nauseous. 

Oxygen starvation, which adversely affects the brain. Hypoxia causes the brain to save its resources, and in order to survive it disables some conscious functions, including the control of body balance. 

Physiological causes - motion sickness on the road, on the rides. The discord between what the organs feel and what the eyes see, watching the waves or moving objects outside the car window, trains, provoke vertigo that is not associated with any disease. 

DPG - the so-called rather mysterious symptom, not studied until the end. Benign positional vertigo dizziness can be a consequence of a cured injury to the head, ear, and DPG is a typical symptom of a hangover.

Dizzy and nauseous because of a panic attack. It is a mental state where fear literally paralyzes a person without objective reasons other than his consciousness. Uncontrolled seizures are often accompanied by stupor, vertigo. 

Drug intoxication can also cause dizziness with nausea. These symptoms are reflex, as the body seeks to get rid of toxic substances as soon as possible with the help of vomiting.

Treatment of the dizziness and nausea

We list the easiest ways that can help if you feel dizzy and nauseous. 

• Orthostatic hypotension. Any change in body position should be performed as slowly as possible. It is necessary to get up from a bed in a special way: having turned over on one side, to hang up legs, then to sit down, then to rise. It is necessary to eliminate the habit that neurologists call "the upper half of the body in front of it runs." In hypotonia, the rush of blood to the head is slowed down; therefore, in this sense, the upper part of the body should follow the trunk. 
• Hypoglycemia, when dizzy and sick, and the whole body weakens to tremor (tremor). Candy, a piece of sugar, even a small slice of bread can save the day. In order not to bring yourself to a hungry faint, you must observe the diet, in case of protracted, chronic manifestations of vertigo, you need to contact a neurologist. 
• The lack of oxygen is compensated by elementary airing and walks. If neither fresh air nor promenades save the situation, consultation with a neurologist is necessary. To delay the visit to the doctor is not worth it, otherwise oxygen starvation can damage important areas of the brain. 
• The physiological cause of vertigo, when dizzy and sick during any movement on transport or visiting attractions, is eliminated with the help of special means - Vertigo Hel, Betaserk. Sleep during travel is also effective, then the movement seen by the eyes does not conflict with the position of the body. 
• DPG, which is accompanied by the characteristic symptom “everything floats” before the eyes, is eliminated by stubborn, long training exercises. Vestibular apparatus can be trained and neutralize dizziness and nausea. If the DPG is caused by alcohol, then the method of help is simple and banal - you should exclude alcoholic drinks from your life. The symptoms of a hangover are relieved by Medichronal, Glycesed, and a further rejection of alcohol.

When dizzy and sick with Meniere's disease, head injuries, panic attacks, epilepsy, self-treatment is unacceptable and even dangerous. In these cases, you need medical care, comprehensive examination and long-term treatment.
