People may describe dizziness as giddiness, light-headedness, unsteadiness or simply feeling faint.
Under normal circumstances, your sense of balance is controlled by a number of signals that your brain receives from several locations; the eye, sensory nerves and inner ear. Good balance depends on at least two of these three sensory systems working well. For instance, closing your eyes while standing does not mean you’ll lose your balance. Signals from your inner ear and sensory nerves help keep you upright.
However, if your central nervous system cannot process signals from all of these locations, or if the sensory systems are not functioning properly ,or if the messages are contradictory, you may experience loss of balance. Most dizziness will go away after a while but it may be symptoms of more serious disorder.
