Dad had a stroke because of A Fib - blood clot. He had been independent up until this point. Walked everyday 6 to 10 blocks, no cane or walker. No salt diet, never smoked or drank alcohol, active social life. 97years old, 124 cholesterol, blood pressure 140/70. After stroke he can walk, talk, light eater, just some memory issues. Doctors put him on bp meds & cholesterol med. So now his blood pressure keeps going down to around 84/50. I feel it's the meds causing the low blood pressure. I keep asking what is the cause. Can't get clear answer. Well he is dehydrated - no the blood work does not show that. Does a 97 year old man need to take this medicine when all his life he never took any medicine?
