Q: Why does BP rise during sexual intercourse? My heart beat increases so much, that I realize that my BP has risen very high. What is responsible for this?
A: Sexual intercourse is a form of activity so it is natural for your blood pressure to go up and your heart to beat faster. With any form of activity, your body needs more oxygen. To deliver the needed oxygen, both heart rate and blood pressure increase. It sounds like you are having difficulty with the physical effort required for sexual intercourse. You should discuss this with your doctor. If your blood pressure is normal, you may just need to start a regular exercise program to build up your physical stamina.
