If you notice this, run to the doctor or call an ambulance.
Just say: in most cases, dizziness is not dangerous. They carry only one risk: if you feel vertigo (as scientists call this sensation), you, if you are very unlucky, can stumble, fall and earn a stretch or abrasion. And most likely, not even this.
However, there are times when dizziness makes one suspect some really serious health problems.
In general terms, the causes of vertigo are simple. Vertigo most often occurs when the connection between the brain and the inner ear is broken, where the vestibular apparatus is located. The brain loses its orientation in space, which makes it feel as if the earth is slipping from under its feet. To stay upright, gray matter triggers a cascade of reactions designed to restore a sense of balance. Some of these reactions also affect the emetic center, which is why dizziness is often accompanied by nausea. So, for example, happens when motion sickness. However, this is a slightly different story.
Fortunately, such loss of contact between the brain and the vestibular apparatus occurs infrequently and lasts just a few seconds. Doctors do not see What Causes Dizziness? in such short-term incidents causes to panic.
Also, do not worry too much if your head is spinning longer, but due to several common reasons. These include:
- alcohol intoxication;
- side effects of medications taken (check the instructions!);
- overheating and heatstroke;
- traveling by car, bus or boat;
- anemia – low iron content in the blood;
- hypoglycemia – low blood sugar levels;
- drop in blood pressure;
- excessively intense exercise;
- ear infections.
Of course, dizziness is always unpleasant. But in these situations, they are one-time and short-term and do not threaten life. And the accompanying symptoms allow you to guess the causes of illness.
Dizziness is not an independent disease, but a symptom that can accompany more than 80 physiological conditions and diseases.
Marked the phrase in most cases? Let us turn to a minority – those states that can carry a real threat to health and even life. And dizziness here is the most important feature.
When dizziness is dangerous
Neurologists identify six states of 6 Signs A Sudden Dizzy Spell Could Be Something More Serious, in which vertigo is the key and almost the only symptom suggesting the development of a serious but still hidden disease.
1. The head is spinning often and longer than several minutes.
This may indicate a serious violation of the Dizziness in the inner ear. For example, about vestibular neuritis (viral infection of the vestibular nerve) or labyrinth (internal otitis).
Such diseases are dangerous because at first they can be almost asymptomatic, and later their pathogens can affect the brain and nervous system – up to a lethal outcome.
2. Dizziness is accompanied by severe weakness, numbness of a part of the body, problems with speech and / or eyesight.
Warning: this combination of symptoms can be a sign of a stroke! A stroke is a violation of cerebral circulation. According to statistics of stroke, it is the second (after myocardial infarction) cause of death in Russia.
Be sure to check out the person who is experiencing this type of dizziness using the one-minute test Got a Minute? You Could Diagnose Stroke:
- Ask the patient to smile broadly, showing off his teeth. If a person has a stroke, the smile will not be symmetrical: the corners of the lips will harden at different levels.
- Ask to close your eyes and raise your hands. A stroke (more precisely, disturbances in the work of nerve endings and muscle weakness) caused by it will not allow the victim to raise his arms to the same height.
- Suggest to repeat your simple sentence of several words. For example: “I’m fine, and now it will become obvious.” If a stroke occurs, it will be difficult for a person to memorize and play a phrase. In addition, his pronunciation will be fuzzy, with a clear lisp on voiced consonants.
Similarly, you can check yourself.
If at least one task fails, immediately call an ambulance. Stroke is extremely dangerous. Stroke statistics: up to 84% of patients die or remain disabled and only about 16% recover. You have only 3–6 hours to try to be among the lucky ones with the help of doctors.
3. You always feel dizzy when you get up
Short-term orthostatic hypotension (decrease in blood pressure, including in the brain, which causes dizziness) is a fairly common condition and not that dangerous.
Most often it is due to the fact that the body lacks fluid. On the basis of mild dehydration, blood becomes thicker, blood circulation deteriorates, so it is not difficult to earn orthostatic hypotension when rising to your feet from a lying or sitting position. Such a problem is solved simply: do not forget to drink water, especially in the hot summer or during severe physical exertion.
But if you are absolutely sure that you do not have dehydration, and dizziness accompanies each of your ascents, it is worthwhile to return to the therapist as quickly as possible. Such symptoms indicate possible cardiovascular diseases (arrhythmia, heart failure) or neuropathy – non-inflammatory nerve damage.
4. You have had bouts of unbearable headache.
Many are familiar with the word migraine, but most believe that it is only a pulsating headache. However, this is not quite the case: prolonged repeated vertigo may also be a migraine.
This neuropsychiatric disorder is potentially dangerous. What is a migraine emergency? for life because it can lead to stroke or heart attack.
If your dizziness lasts several hours or more, occur regularly, and in the past you have a headache, be sure to consult with a therapist to establish their possible causes and consequences.
Warning: you may need hardware diagnostics – CT scan or MRI, the direction to which the doctor will issue again.
5. You recently hit your head
Vertigo is one of the most prominent symptoms of concussion. It is important to contact a physician as soon as possible in order to exclude serious injuries and swelling of the tissues.
6. During training you are constantly dizzy
Most often in such states the already mentioned dehydration is to blame. Or hyperventilation: due to rapid breathing in the blood, the level of oxygen rises and the content of carbon dioxide decreases, which causes dizziness. Therefore, it is important to drink an adequate amount of fluid loads and not be too zealous with cardio.
If you are absolutely sure that you drink your water rate, and your head starts spinning even during the absolutely “pensioner” exercises, take a look at the doctor. In this case, it is necessary to exclude the possibility of potentially dangerous cardiovascular disorders.
