Question: Can I ever stop taking medicine for high blood pressure to see if diet and lifestyle changes have brought my blood pressure back to normal?
Answer: Hypertension (high blood pressure) is the most common form of cardiovascular disease in North America, affecting nearly one in three adults. High blood pressure is a threat because it makes the heart work harder, increasing its oxygen demands and contributing to angina (chest pain related to heart disease).
Unchecked, high blood pressure increases the risk of heart attacks, stroke and kidney disease. Some people can lower and control their blood pressure with healthy lifestyle measures — losing weight if necessary (even a 10 per cent weight loss might do the trick), quitting smoking if that’s an issue, limiting intake of caffeine and alcohol, as well as cutting back on salt (processed foods are the biggest sources of sodium in today’s western diet) and practising relaxation methods.
The last of these may be the most important, yet doctors often fail to emphasize the importance of learning how to relax the involuntary nervous system, which controls the tone of blood vessels. Meditation, yoga, breathing exercises and biofeedback training can all help. I recommend that you also check out a simple device called RESPeRATE (resperate.com) that teaches you to lower your blood pressure by changing your breathing patterns.
If you’ve made and are maintaining these lifestyle changes, you might then try to cut down on your blood pressure medication. Do so gradually, and be sure to monitor your pressure at home — at least two to three times a day, both when you are calm and when you are not — to make sure that it doesn’t start to rise. If it does, you’ll have to return to the usual dosage of your medication. It would be best to make these changes under the supervision of your physician so you will not be alone in your efforts.
A large study from the U.S. Centers for Disease Control and Prevention published in the May 4, 2007, issue of Morbidity and Mortality Weekly Report found while most Americans who have high blood pressure are trying to bring it under control, 70 per cent of them have failed.
The CDC researchers collected information on more than 101,000 people and found that of the nearly 25,000 who had high blood pressure, 98.1 per cent, said they were doing at least one thing to lower it. Nearly 71 per cent said they had changed their eating habits, 79.5 per cent said they had reduced or eliminated the salt in their diets, 79.2 per cent either didn’t drink or had cut back on alcoholic beverages, 68.6 per cent exercised and 73.4 per cent were taking medication. But the study showed that those efforts paid off in only 30 per cent of all cases.
If you have a family history of hypertension, lifestyle measures may not be enough to keep your blood pressure under control — you probably will need some medication. But no one should depend on drugs alone. A healthy lifestyle, including relaxation practise, is also key to keeping blood pressure in the safe range.
