Dizziness refers to a loss of balance or unsteadiness that can often be accompanied by a sensation of faintness and/or lightheadedness.
Note: True vertigo is caused by a problem somewhere within the middle ear, eighth (acoustic) cranial nerve, the brain (brain stem), or the eyes. Unlike dizziness, vertigo is usually associated with nausea, vomiting, and severe sweating, and is mainly caused by a viral infection in the canals of inner ear or Meniere`s disease, which is characterized by bouts of severe nausea, vomiting, ringing in the ears (tinnitus), hearing loss, and dizziness that can persist for days and weeks.
Dizziness is usually caused by a sudden drop in blood pressure in the brain as a result of standing up too quickly (postural hypotension), fatigue, stress, low blood sugar (hypoglycemia), temporary blockage of blood to the brain as in a transient ischemic attack, low blood oxygenation (anemia), low blood iron, and/or certain drugs.
Lightheadedness, giddiness, and fear of losing one`s balance may be a sign of depression or anxiety.
Some cases of dizziness can also be due to mercury poisoning from dental amalgams. If you have such fillings in your teeth, consider having them replaced by a holistic dentist trained in their proper removal (see Holistic Dentistry).
If dizziness is caused by standing after sitting or lying down, this can be an indication of adrenal exhaustion. The individual should take action to restore adrenal health by stopping the use of stimulants (caffeine, tobacco, alcohol) and via rest and normalization of lifestyle and nutritional balance.
Caution: Severe or prolonged dizziness needs to be evaluated by a health professional and may require blood tests.
