Possible Causes of Dizziness
Feeling dizzy is disconcerting. There are two different types of dizziness. It could be that you feel lightheaded. This is when you feel faint, and that you could pass out. You may even feel a bit nauseated. Another form of feeling dizzy is when you are experiencing vertigo. This is different from feeling lightheaded---you feel as though the things around you are moving, though you are not. You may feel as though you are spinning or whirling.

Anxiety
-
Stress affects the body in many different ways. According to eMedicine Health, stress often leads to anxiety. If you suffer from stress and anxiety often, you may feel dizzy. One of the main reasons that people feel dizzy is that they don't receive enough blood to the brain. If you are having panic or anxiety attacks, often your breathing is not consistent. That leads to feeling dizzy and disoriented.
Low Blood Sugar
-
Another possible cause of dizziness is low blood sugar, also known as hypoglycemia. According to Linda J. Vorvick, MD, low blood sugar occurs when too much insulin is released into the bloodstream, or the glucose in your body is used up too quickly. This leads to myriad symptoms, including dizziness. This can occur if you eat the wrong kinds of food, or don't eat enough food.

Medication
-
According to WebMD, medication often has side effects like dizziness. (References 3) This is particularly the case when you are taking sedatives, antidepressants, antibiotics or blood pressure medicine. Medication can cause dizziness by causing dehydration, or by altering chemicals in the brain. Tranquilizers and sedatives will lead to dizziness if you try to be too active after taking them.
Illness
-
The common cold or the flu is often accompanied by dizziness. This type of dizziness is usually more of the light-headed variety. While you're suffering from an illness, rest is the best way to avoid being dizzy. Also, drinking copious amounts of fluids is helpful, as illness can also lead to dehydration.
