My father has a problem with high blood pressure. I’m worried because he drinks a lot of cups of coffee every day. He knows that it’s not good for him but he can not stop drink it. Can somebody explain to me How does caffeine affect blood pressure? Does he really need to stop to drink coffee?

Caffeine may increase your blood pressure. People without high blood pressure need to be very careful with caffeine. I read somewhere that the amount of caffeine in two to three cups of coffee can raise systolic pressure 3 to 14 mm Hg and diastolic pressure 4 to 13 mm Hg. You father should try to reduce his intake of caffeine.
