Dizziness is a sensation of light-headedness - a feeling in which everything around appears to be spinning. There are various causes of dizziness, and it can be treated by identifying the exact cause. It is not a disorder or a disease, but it is a symptom that can be due to a disease or lead to a disease.

Dizziness may occur due to an imbalance in the sensory functioning between the eyes, sensory nerves and inner ear, leading to vertigo. It may also occur due to circulatory problems, neurological conditions, anxiety disorders, low levels of iron, low blood sugar levels and dehydration. Certain medications are also responsible for causing dizziness.

Problems in blood circulation can lead to dizziness. Conditions, such as blood clots, clogged arteries and irregular heartbeats, cause low blood supply to the brain, depriving the brain of oxygen-rich blood. It can lead to lightheadedness, and the person may faint.

Migraine can lead to headache, light-headedness, noise and light sensitivity. It can also lead to episodes of vertigo, thereby causing dizziness.

There are complications associated with dizziness. It increases the risk of falling with a severe injury. If a person feels dizzy while driving or operating heavy machines, the risk of accidents increases. The exact cause of dizziness needs to be diagnosed and treated to avoid recurrence.
