How dizziness relate to common cold?

Dizziness is when a person experiences light headedness, feels unsteady and finds everything around him spinning or moving. Dizziness is not a serious concern, as it can be cured in a short period of time.

The problem of light headedness arises when there is a shortage of blood supply in the brain. This might happen when there is a decrease in blood pressure, or dehydration takes place due to fever, diarrhea, vomiting and other causes. Older people sometimes experience dizziness when they tend to rise up quickly from bed or chair. Light headedness can also show up after common cold, flu, hypoglycemia and allergies.

The most serious effects that dizziness can bring about are heart problems such as heart attack, stroke and severe decrease in blood pressure. However, these effects have the symptoms of loss of speech, racing heart and chest pain.

During dizziness, one should avoid rapid changes in their posture. Intake of a lot of fluid might help, and one might also require intravenous fluids if he is unable to hold the fluid in his body. This fluid is delivered in the hospital. Most of the time dizziness goes away within a week. During this time, the patient should take as much rest possible.
