I know when my mother high blood pressure was high, and her blood sugar level was high her temper was bad. that I use to get confused thing her temper was down to her AZ, but when they level out her temper fine . PS Thinking about it nurse done her blood pursuer when her diabetic was out of control sugar level really high also blood pursuer , Nurse / doctor warn me to keep it under control Or it make her AZ worse . mum lost her temper with nurse and I . Then when she came around again and mum sugar level was fine, also her blood purser , as doctor had up her blood purser medication . she was fine with nurse , since I have now got it all under control, she was even fine with nurse coming around to take her bloods the other day .
