Sudden dizziness and nausea are very common in public life. Everyone meets them at least once in their life. However, in some people, the ongoing condition is a medical condition. The information below will give more knowledge about this disease, its causes, and its treatment and prevention.
What is dizziness, nausea, headache, fatigue?
One morning, the patient woke up, opened his eyes, was about to sit up to get out of bed when suddenly, severe dizziness appeared. The patient feels that everything around him is spinning, houses are collapsing, tables and chairs are moving or somersaulting. This will naturally come to them, causing them to panic and fear inevitably. At this time, the more worried they are, the more intense they will feel dizzy and dizzy. In some cases, there is also nausea, vomiting, headache, fatigue.
This condition is widespread in the population, especially in middle-aged people, with more women than men. The prominent feature is that dizziness is often related to posture, increases when the patient sits up, turn the head, and decreases, utterly relieved if they lie still, close their eyes. That’s why this condition is called “benign paroxysmal postural vertigo” in medicine. Episodes of vertigo usually appear in series that last for a few days to a few weeks, then go away on their own and will return after a few months to several years.
However, in some cases, the symptoms of headache, dizziness, nausea, vomiting do not change or decrease with position and rest, it is necessary to think of more dangerous neurological diseases: cerebral infarction, increased In this case, the patient should go to a medical facility for examination, monitoring and emergency treatment.
Is this disease dangerous?
As the name suggests, benign postural vertigo does not cause serious complications.
During vertigo, the patient is terrified, extremely worried, feeling that the house is spinning upside down, tilted. However, they will find themselves that when turning their head, looking around will worsen symptoms, promote nausea, vomiting, so they tend to close their eyes and lie still. After that, the dizziness will subside on its own for a minute or two before disappearing completely.
In other words, the disease is entirely benign if the patient rests in bed, being careful not to fall or get injured if he tries to walk.
Besides, when examining, doing tests, cranial imaging will also not record any abnormal signs. The patient is not entirely paralyzed or has any focal neurological symptoms; Ear examination was also standard, with no changes in hearing.
What causes this disease?
To date, there have been many theories about the cause of benign paroxysmal vertigo, but most of them have not been proven. Of these, the hypothesis of the presence of small stones in the cochlea seems the most convincing.
The vestibule is considered a sense, sensing posture in space, thereby helping to maintain stability, body balance, posture, and coordination of eye, head, and trunk movements. The vestibular system consists of a receptor, the semicircular canal located in the cochlea, nerves that conduct and analyze signals in the brain.
The cochlea is attached to three rings of semicircular canals, arranged in three different spatial planes. The circulation of fluid in the semicircular canals helps the body orientate the posture. Therefore, when the body changes in a specific direction, the stone particles move in the semicircular canal in that plane, which will stimulate the vestibular system, send signals to the brain, and initiate the sensation of dizziness. . As a result, the body has a reflex to lie still, keeping the head position where it feels most secure. The pebbles do not move anymore, the feeling of dizziness will subside.
Besides, it is necessary to differentiate from other diseases that also have symptoms of dizziness when central and peripheral vestibular organs are damaged, such as inflammation, sclerosis, degeneration to ischemia, haemorrhage. Or injured. The difference, however, is that vertigo in these conditions has nothing to do with posture.
What are the treatment and prevention?
Benign paroxysmal vertigo is exactly what the name suggests if the patient knows how to avoid triggers, adhere to vestibular stabilizers, and perform tests to reposition the semicircular canal.
Avoid changing positions too suddenly and too quickly.
At all times, always remember not to change positions suddenly and quickly. Specifically, when switching from a lying place to sitting up, standing up, or turning the head, bowing and tilting must also be done slowly and slowly. After establishing the pose at the new position, slowly open your eyes. It is best to close the eyes to limit the visual reception of spatial change signals, reducing vestibular stimulation.
If you find that dizziness often occurs when you wake up, in your sleep, you should use many pillows to prop your head up, should lie on your back, avoid leaning to one side. In addition, do not sit on a swivel chair or chair with a headrest that tilts back too much, limiting excessive leaning and bending movements such as picking up things, tying shoelaces.
Groups of drugs can help correct vertigo during acute attacks and relieve symptoms of nausea and vomiting.
Antihistamines should only be used when the patient has severe dizziness that does not improve after postural stabilization. Some sedatives can be added if the patient is overstimulated, anxious, or scared.
However, drugs acting on the central nervous system will have side effects such as drowsiness, lethargy, and dizziness that are difficult to go away completely. Therefore, it should only be used when necessary and adhere to the dosage as directed by the doctor.
Exercises for the vestibular system
Currently, the treatment of benign paroxysmal vertigo tends not to use drugs but to apply exercises to reposition the stones in the semicircular canal, helping the vestibular system recover and adapt to the displacement in the air. Body space.
Exercises can be done right in the clinic with the support of physiotherapists, or the patient can practice at home. If done correctly and patiently, unpleasant symptoms will improve significantly.
When dizziness occurs, it is necessary to stay calm, close your eyes, limit your head rotation and find a suitable position to rest. If you feel nauseous, you should control it by taking deep breaths and focusing on your breathing. Just follow this; the dizziness will quickly subside in a few minutes.
- Do not walk long distances, do heavy work, climb, operate vehicles or machinery when dizzy. Because these things cause more severe dizziness, are longer-lasting, and can even cause accidents for yourself and others.
- Keep the space in the room, the aisle clear, avoid messy and indiscriminate items. Add handles in bathtubs and toilets.
- Drink enough water every day, eat a balanced, varied diet rich in vitamins and minerals. Avoid drinking coffee, alcohol, carbonated soft drinks.
- Do not use stimulants, smoke, or be exposed to secondhand smoke.
- Get enough sleep, rest in moderation, think optimistically. Have appropriate and moderate exercise habits.
In summary, benign postural paroxysmal vertigo is a common disease in the community. Information about the condition and how to respond and prevent it is essential to overcome these unpleasant symptoms and confidently enjoy life.
