Dizziness is described as a state of lightheadedness and unsteadiness. This typically affects the sensory organs particular the ears and eyes. Take note that dizziness can cause fainting. This is not a disease but a symptom of certain disorders.
Essentially, dizziness is a feeling of lightheadedness or nearly close to fainting. Dizziness is quite common and the underlying cause is not serious in most cases. On the other hand, it is best to seek medical attention if the individual experiences recurring bouts of dizziness without any cause. It is vital to seek immediate medical care if the individual experiences abrupt dizziness after a head injury that is accompanied by neck ache, headache, hearing loss, blurry vision, loss of consciousness and chest pain.
Causes of dizziness
The common causes of dizziness include interior ear disorders, alcohol and certain medications. In most cases, dizziness is often due to vertigo. It can also be caused by problems in the interior ear in which balanced is controlled.
Both dizziness and vertigo can be due to Meniere’s disease, acoustic neuroma, migraine and benign growth on the nerve connecting the interior ear to the brain. In rare cases, vertigo can be caused by brain hemorrhage, stroke, multiple sclerosis or other neurological disorders.
Other causes of dizziness include an abrupt drop in the blood pressure, anxiety disorders, anemia, ear infection, hypoglycemia, heatstroke, motion sickness and dehydration.
Symptoms of dizziness
- Loss of balance
- Floating sensation
In some cases, dizziness is accompanied by nausea and vomiting, clamminess, paleness or loss of consciousness.
A doctor typically diagnoses dizziness and the underlying cause after performing a physical examination. Questions will be asked regarding the dizziness including when it occurs, positions that triggers it, severity and other accompanying symptoms.
The doctor will also check the eyes and ears of the individual, observe the posture and carry out tests to check the balance. In some cases, a CT scan or MRI might be requested.
Treatment for dizziness
The treatment for dizziness mainly centers on the underlying causes. In most cases, lifestyle changes, home treatments and medications can help control the cause. In case of Meniere’s disease, it is usually treated with diet or even ear surgery.
Migraines can be treated with lifestyle changes and medications. Administration of medications can help relieve the pain and nausea. Drinking adequate amounts of fluids can help if the dizziness is caused by heat, dehydration or excessive exercise. Alcohol, tobacco, caffeine as well as substances that can disrupt the balance or trigger dizziness must be avoided.
Always remember that most cases of dizziness typically clear up once the underlying cause is treated. In rare cases, dizziness can indicate a serious health issue. Bear in mind that dizziness can lead to serious complications if it causes fainting or balance loss that can be dangerous if the individual is driving or using heavy machinery.
