There are many ailments that can bring about the symptom of dizziness, including heart circulation problems and irregular blood flow. High or low blood pressure can often bring on a bout of dizziness.
Blood flow is a major factor in bouts of light-headedness. If there is not enough blood flowing to the head, dizziness may result.
Other ailments or illnesses that cause dizziness include low blood sugar, fevers and stress.
Anxiety or panic attacks are usually accompanied by a bout of dizziness. The room may begin to feel as if it is spinning when a panic attack occurs.
In medical terms, there are three different types of dizziness. These are classed as vertigo, syncope and non-vertigo non-syncope.
The most common causes of dizziness are activities everyone experiences, at least as children, namely running around in circles or riding carnival attractions that spin, loop or twist.
But dizziness can also occur as an unprovoked and severe episodic or even constant occurrence--an understandable source of distress for the person experiencing it.
Vertigo refers to the sensation of being in a spinning environment.
Light-headedness is a very different type of dizziness that does not involve the apparent movement of the environment.
Some patients describe dizziness not as a sensation in their head, but rather as a feeling of being off-balance when walking.
