From causes to treatment and lifestyle adjustments
"A sudden feeling of spinning," "feeling lightheaded and having difficulty walking," "feeling dizzy when standing up"—all of these symptoms are called "dizziness." Dizziness is a symptom that many people experience at some point, but its causes and treatments vary, making a proper understanding very important. In this column, we will explain the types and causes of dizziness, as well as the medications used to treat it, in an easy-to-understand way.
What is dizziness?
Dizziness can be broadly divided into three types.
The first type is "rotational vertigo." This type makes you feel like you or your surroundings are spinning, and is often caused by abnormalities in the "inner ear," which is located deep inside the ear. Representative conditions include "benign paroxysmal positional vertigo (BPPV)" and "Meniere's disease."
The second type is "floating vertigo." It is characterized by a feeling of floating or being unable to keep one's feet on the ground, and is often related to an imbalance in the brain or autonomic nervous system.
The third type is the "orthostatic dizziness (syncope) type," where you feel dizzy when you stand up. This can be caused by low blood pressure, dehydration, anemia, etc.
Thus, dizziness is merely a symptom, and it is important to identify the underlying cause.
Causes of dizziness
There are three main causes of dizziness:
① Abnormalities of the ear (inner ear)
Rotational vertigo can occur when there is a problem with the inner ear, which is responsible for balance. This can be related to displaced otoliths or abnormalities in the lymphatic fluid.
② Abnormalities of the brain or nerves
It can sometimes be caused by serious illnesses such as cerebral infarction or cerebral hemorrhage. If you experience symptoms such as slurred speech or numbness in your hands and feet, you should see a doctor immediately.
③ Overall physical condition and lifestyle
Low blood pressure, dehydration, stress, and lack of sleep can also cause dizziness. In particular, dizziness caused by autonomic nervous system dysfunction is increasing in modern times.
Main medications used for dizziness
In treating dizziness, various medications are used depending on the cause and symptoms.
① Medications that improve blood flow
Dizziness can be alleviated by improving blood flow to the inner ear and brain. A typical example is Diphenidol (brand name:CEPHADOL ). This improves blood flow to the inner ear and is widely used for conditions such as Meniere's disease.
Diphenhydramine② Drugs that suppress nerve excitation
These medications are used to relieve nausea and discomfort caused by dizziness. Examples include diphenhydramine and diazepam, and are used when symptoms are severe.
③ Antiemetics (medications to stop nausea)
These medications are used to suppress nausea and vomiting associated with dizziness. Metoclopramide and domperidone are typical examples.
④ Diuretics
Meniere's disease is thought to be caused by an increase in lymphatic fluid in the inner ear, and diuretics may be used to drain the excess fluid.
⑤ Herbal medicine
Traditional Chinese medicine is also used depending on the patient's constitution and symptoms. For example, Hange Byakujutsu Tenma-to is sometimes used for people with weak digestive systems and who are prone to dizziness.
Precautions when using medication
Many medications for dizziness only alleviate the symptoms and do not completely cure the underlying cause. Therefore, it is important to take them appropriately and follow your doctor's instructions.
Furthermore, many medications cause drowsiness, so caution is necessary when driving or performing dangerous tasks. Antihistamines, in particular, tend to cause drowsiness.
Furthermore, avoid stopping medication on your own or using someone else's medication. Depending on the cause of your dizziness, using the wrong medication may worsen your symptoms.
Measures you can take in your daily life
In addition to medication, reviewing your lifestyle habits is also extremely important for managing dizziness.
Get enough sleep
Drink plenty of fluids.
Don't stand up suddenly
Don't let stress build up.
Try to live a regular life.
In particular, in cases of benign paroxysmal positional vertigo, head movements and exercises (rehabilitation) can sometimes be effective.
Dizziness that warrants immediate medical attention
If you experience any of the following symptoms, please seek medical attention immediately.
I can't speak clearly.
Numbness or paralysis of the hands and feet
accompanied by a severe headache
I feel drowsy.
These could be signs of a brain disorder.
summary
Dizziness is a common symptom, but its causes are varied, requiring proper diagnosis and treatment. While medication can alleviate symptoms, lifestyle changes are equally important.
Don't take dizziness lightly; it's important to consult a doctor early if you have any concerning symptoms. Let's work together to ensure you can live your daily life with peace of mind while managing your medication effectively.
