Dizziness and Vertigo

The sensations associated with dizziness can be feeling lightheaded, unsteady, floating, giddy and nauseous or motion sickness.

You may feel unsteady when you stand up and may even fall over. This may be accompanied by nausea and vomiting.

Feeling dizzy or unsteady can be caused by many factors such as:

  • Medication
  • Injury
  • Infection
  • Allergy
  • Neurological disease such as tumours or multiple sclerosis
  • Anxiety and tension
  • Meniere’s disease, which is a serious middle ear disorder that is also associated with tinnitus
  • Inner ear disease
  • Poor circulation

Dizziness is treatable but first you need to see your doctor or a Vertigo Specialist to determine the exact cause of the dizziness.  Dr Katzen offers vertigo treatment in Sydney.


Causes of Vertigo

If your brain does not get enough blood flow, you can feel light headed.  This can be due to poor circulation and can be a chronic condition, caused by a hardening of the arteries because of high blood pressure or diabetes.

Sometimes this is seen in patients who have impaired heart function, low blood sugar or anaemia.

Certain drugs and substances can also decrease the blood flow to the brain like caffeine or nicotine.

Emotional stress, anxiety and tension can also impair circulation by causing spasms in the arteries and also muscle tension.

If the inner ear does not receive enough blood flow, a more specific form of dizziness called Vertigo occurs.

The inner ear is incredibly sensitive to even the slightest alterations of blood flow and all of the causes mentioned for poor circulation to the brain also apply to the inner ear.

Vertigo and all forms of dizziness relate to the sense of equilibrium and balance.  The dizziness associated with vertigo is experienced as an illusion of movement of one’s self or the environment around you and can be very disconcerting.


We will take a very thorough history of your health and will also examine your ears, nose and throat.  Other routine tests will be performed to check nerve and balance function and your hearing. A hearing test is called an audiogram.

Possible additional tests may include an MRI or CT scan of your head and neck. The examination will also include a neurological testing to assess the function of the brain and eyesight of the patient.

Sometimes special tests of eye motion after warm water, cold water or air is used to stimulate the inner ear.

Treatment of Dizziness

Most cases of dizziness are easily treatable.  Treatments may include medications, balance exercises or massage.  In very rare cases, surgical intervention may be required for which you need ear surgery by an ear doctor, such as Dr Katzen in Sydney.
