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.
One of the most common causes of symptoms like light-headedness, fainting, muscle weakness or tiredness is dehydration. This occurs when the body uses more fluids than are taken in or ingests diuretics that deplete the body of water. The body responds by lowering the blood pressure and slowing down kidney functions.
