Lightheadedness-Feeling lightheaded now and again is pretty common. Usually it is not caused by a serious problem. What causes dizzy spells in the case of lightheadedness is often a drop in blood pressure and blood flow to the head from standing up too quickly after lying down or sitting. This is called orthostatic hypotension. There are many other causes of dizzy spells of this type, such as: 1  Allergies. 2  Illnesses (flue, colds, anything that causes congestion of the sinuses and ears). 3  Vomiting, fevers, diarrhea, and any other illness that causes dehydration. 4  Rapid or very deep breathing (hyperventilation).
