HIGH BLOOD PRESSURE
The mistake your doc may be making: Sticking with lifestyle changes when you need drugs.
The evidence shows that it's safe to try to bring down mildly elevated blood pressure by eating better and exercising. But if your numbers are even moderately high, the advice is unequivocal: Your doctor must prescribe drugs because uncontrolled high blood pressure puts you at risk for a deadly heart attack or stroke.
Guidelines making this clear were crafted by a panel of leading scientists in 2003. But when 22 community doctors were asked by University of Texas researchers how they'd treat a hypothetical middle-aged man with the moderately high blood pressure of 145/92, nearly two thirds said they'd tell him to improve his lifestyle. Shockingly, only one of these practicing physicians was familiar with the recommended thresholds for prescribing drugs, says study author Joseph Ravenell, MD, now at New York University.
The right move: If your blood pressure is 140/90 or higher, you should almost certainly be on a prescription hypertension drug—and if one medication doesn't bring your readings into the normal range, you should be on more than one. Only people diagnosed with prehypertension (120 to 139 over 80 to 89) can get by with lifestyle changes alone. Those include exercising, losing weight if necessary, and eating a healthy, low-fat, low-salt diet.
