Hi doctor, my father has bp problem. His age is 60 years. Since last 2 month his bp is much fluctuating. Its like 140 to 185 some times in lower 65-90. He is taking medicine 3 time in a day. If he forget to take medicine than he face the issue. I think medicines are not suitable to him. Now if he is walking than also he is feeling uncomfortable after 10 minutes and bp goes high also in 10 min. What to do? went to many doctor but not good results.
