Can hypovolemia cause high blood pressure?

Answer 1

Hypovolaemia is the medical name for "low volume". It refers to the circulatory system. You can be very dehydrated because of not drinking fluids and your blood volume would be decreased but this would cause you to have a low blood pressure. You would feel faint and perhaps see stars when you stand from the sitting/lying position. Blood volume can also be low due to blood loss following serious trauma, a cut, or because of a perforated stomach ulcer for example. This would also cause your blood pressure to fall. As a hospital patient you would probably be given an infusion of saline if you are dehydrated of a blood transfusion if you have has blood loss. In either case, if these flow in to your system too fast this may cause you blood pressure to be high. You could also have other complications loke breathlessness. Hope this helps.
