Hello Doctor, HRU, i am monitoring my BP my upper arm digital monitor in the moring it is always above 14o systtolic and above 80 in dyastolic. when I check in the clinc it is always 130/90or 130/80. Actually I was taking the medicine candesartan cilexetil 8 mg daily, but suddenly my BP dropped to 105/75 and went to the GP and was told stop medication. He monitored 10 days without medication it was in normal range, then the doctor adviced me to come and check your BP after a month. Doctor please advise me why the difference between the morning BP and evening BP.
