What is lightheadedness?

Lightheadedness is a sensation as if about to faint. The body might feel heavy while the head feels that it is not getting enough blood. This might be accompanied by cloudy vision and balance loss.

It often occurs if moving rapidly from a seated to a standing position. The change in position causes a drop in the flow of blood to the brain. The drop in the blood pressure causes one to feel faint. One is likely to experience this condition if dehydrated due an ailment or poor intake of fluid.

What are the causes?

Aside from dehydration and positional changes, other usual causes of lightheadedness include:

  • Having common cold or flu
