Symptoms of hypotension occur when the body is unable to compensate for the loss of blood volume due to dehydration, bleeding or another cause. Blood flow to the kidneys decreases to reduce the formation of urine and thereby increases the volume of blood in the arteries and veins. Low blood pressure has many different causes including: Emotional stress, fear, insecurity or pain (the most common causes of fainting) Dehydration, which reduces blood volume The body’s reaction to heat, which is to shunt blood into the vessels of the skin, leading to dehydration Congestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly.

Low blood pressure is usually most serious when it results in a prolonged reduction in the blood flow to critical organs. The rapidly contracting ventricles do not have enough time to fill maximally with blood before each contraction, and the amount of blood that is pumped decreases in spite of the faster heart rate. Moreover, a sustained heart rate over 100 beats per minute can eventually compromise the heart muscle itself, increasing the risk of heart failure and sudden death.. National Kidney Foundation.
