Dr.'s don't get paid more money to write you a prescription. There's a lot of misinformation out there.
BP, diabetes, and lipid levels (cholesterol, HDL's, LDL's,etc ) are affected by a multitude of factors. If you think your last jet ski build was complex try figuring out the human body. The regulatory pathways are still being studied and figured out. Consider that jet skis have evolved in terms of riding style, technique, builds, and technology. As does medicine. It should not be surprising to anyone that updates have been made since the Framingham study. As with many health problems starting with diet, exercise, better sleep habits, stress managment, etc is excellent, preferred and often effective although unfortunately not always. I would bet your physician would be glad to hear that you did these first and continued them. If you don't believe your doctor than check your BP yourself several times a day at home and record it in a journal. Present them the data or find a doctor that you trust and go from there. A single reading at one visit is not reliable to manage this type of problem. Also many people will present examples of "having hypertension without any bad problems" and maybe you'll get away with it kind of like the guy you know who smoked and lived to his 90's. It's a game of numbers. It's imperfect. You're optimizing. I'd just be a little wary of the keyboard cowboy's eagerly dealing out expert opinions on big pharma, home remedies and physician reimbursement. Also supplements and herbals can be effective. Where do you think "big pharma" gets the chemical compounds to manufacture meds? They just happen to have a bit more stringent quality control, dosage optimization, data, and FDA oversight. Admittedly, it's not perfect. Just something to consider when you're deciding whose opinion to trust.
Glad you got your BP down.
