BP 106/49 pulse 71, I have never seen the Diastolic that low but have seen systolic as low as 91. I am on no prescription meds. I am 68, female 135 lbs. I do water exercise every morning for at least one hour, usually more. What can possibly be causing low blood pressure even right after exercise. I eat more fruits and veggies then meat, I seldom eat bread, pasta or potatoes usually no sweets but I did today, a small piece of strawberry shortcake. I drink coffee, tea, water, seldom anything else. Dr. said I am in fantastic health for my age. When I go for a yearly physical I am told my blood pressure is quite high, good thing I take it at home and know its just white coat syndrome.
