What are the signs and symptoms of low blood pressure?
Low blood pressure may or may not cause symptoms. Many symptoms get worse when the person stands. The patient with chronic low blood pressure may complain of lethargy, weakness, fatigue, and dizziness. The patient may faint, especially if arterial pressure is lowered further when he assumes an erect position. These symptoms are presumably due to a decrease in perfusion of blood to brain, heart, skeletal muscle and other organs.
