Dizziness includes the feeling of being lightheaded or unsteady. You may also feel like you are spinning, tilting down to one side including even other extreme vertigo-related feelings
Dizziness is often caused by illnesses that affect the inner ear, such as benign paroxysmal positional vertigo (BPPV), migraine, and inflammation of the inner ear balance apparatus (called vestibular neuritis).
Dizziness may also be caused by low blood pressure, some heart problems (such as cardiac arrhythmias), anxiety disorders such as panic attacks, or (uncommonly) hypoglycemia (low blood sugar).
While some people understandably find it difficult to describe their dizziness, a description of a person’s dizziness and the circumstances in which it occurs may be very helpful in reaching a diagnosis. (source)
Symptoms of dizziness and vertigo
Descriptions of dizziness may include:
- a sensation of movement (including spinning), either of yourself or the external environment
- unsteadiness, including finding it difficult to walk in a straight line
- feeling faint.
Other symptoms that may accompany dizziness include:
- nausea and vomiting
- ringing or other sounds in the ears (tinnitus)
- difficulty hearing
- staggering gait and loss of coordination (ataxia)
- unusual eye movements, such as flitting of the eyes (nystagmus)
- finding it difficult to see clearly when moving, for example, when reading a sign while walking or driving.
What causes dizziness?
A number of conditions can cause dizziness because balance involves several parts of the body. The brain gets input about movement and your body’s position from your:
- Inner ear.
Inner ear disorders are frequently the cause of feeling dizzy. The most common causes include benign paroxysmal positional vertigo (BPPV), Meniere’s syndrome, and ear infections.
What Are The Common Causes of Dizziness
Common causes of dizziness include a migraine, medications, and alcohol. It can also be caused by a problem in the inner ear, where balance is regulated.
Dizziness is often a result of vertigo as well. The most common cause of vertigo and vertigo-related dizziness is benign positional vertigo (BPV). This causes short-term dizziness when someone changes positions quickly, such as sitting up in bed after lying down.
Dizziness and vertigo can also be triggered by Meniere’s disease. This causes fluid to build up in the ear with associated ear fullness, hearing loss, and tinnitus. Another possible cause for dizziness and vertigo is an acoustic neuroma. This is a noncancerous tumor that forms on the nerve that connects the inner ear to the brain.
Some other possible causes of dizziness include:
- a sudden drop in blood pressure
- heart muscle disease
- decrease in blood volume
- anxiety disorders
- anemia (low iron)
- hypoglycemia (low blood sugar)
- ear infection
- excessive exercise
- motion sickness
In rare cases, dizziness could be caused by multiple sclerosis, a stroke, a malignant tumor, or another brain disorder.
