Does blood pressure go up when you get sick? Does it go back down when you are no longer sick?
You may see a rise in blood pressure when you are sick, especially if there is an infection or you have a fever. When the body is physically or emotionally stressed it can cause the blood pressure to be elevated and when you are no longer sick it should go back to what you normally run. It has been shown typically during the winter a person's blood pressure runs a little higher than when it is warmer because the blood vessels are constricted to conserve energy.
