Lotkowski said dizziness is also compared to feeling faint or lightheaded, and may be accompanied by nausea and skin clamminess. A drop in blood pressure which can occur after sitting up or standing too quickly could cause this, as well as inadequate output of blood from the heart.
Heavy menstrual bleeding also can cause this type of lightheadedness. Sometimes the cause of lightheadedness is an abnormal heart rhythm , which can cause fainting spells (syncope). Unexplained fainting spells need to be evaluated by a doctor. You can check your heart rate by taking your pulse. Many prescription and nonprescription medicines can cause lightheadedness or vertigo. The degree of lightheadedness or vertigo that a medicine causes will vary.
