Hello in college I had a physical and the doctor for the first time said I should watch my blood pressure. I did not worry about it for a while until after college. I recently got a blood pressure monitor and have been taking my blood pressure. During the day my systolic blood pressure ranges from 120-150. This makes me a little nervous. The weird thing is my diastolic pressure is always very low. Like 50-60 during the day. This morning upon waking my blood pressure was 116/45. I looked up the reason for this and I read that it means your arteries are deteriorating, but this is usually only a sign of that for older people. What does it mean for younger people? I am 24 years old 6'2 220 pounds. My heart rate during the day when I take these readings is about 60 beats/min.
