I have had low blood pressure for 69 years, ll months. February l, 2013, it spiked to l95/l05. It continues to spike about once a month. I am on Lisinipril - started with l0 mg, now 20 mg - still spiking - usually at evening/ night. My Dr. has run all sorts of tests - nothing shows. HELP!!
Hi, fluctuating blood pressure is very common, but huge jumps from low BP to over 190 is unlikely.  Diet variations and stress levels are the two most important causes for rapid changes in BP. Autonomic neuropathy patients can also show huge variations in BP.  I suggest you to keep your salt intake constant and maintain good physical exercise, try yoga for stress reduction.  Hope this will help.
