One of the goals when you take drugs for high blood pressure is to be sure the medication is working effectively. One step toward achieving this goal is to avoid some medications. What kinds of problems might other drugs cause?
Some drugs can make blood pressure rise. If you have high blood pressure to begin with, it can rise to dangerous levels.
Some medications may interact with blood pressure medicine. This can prevent either drug from working properly.
Here are common types of medication...
"Salt," he said firmly, scribbling something in my chart. "Pretzels, chips, French fries, anything with added salt. Let's give it a try and see if we can get these numbers down a bit. Otherwise we may want to start you on a blood pressure medication."
Ouch. If anything could get me to swear off salty goodies, it's the threat of having to take a pill for the rest of my life. But can cutting down on salt really lower blood pressure?
For years, the advice on salt has flip-flopped. Some experts say too much can send blood pressure climbing. Others have said that for most people salt isn't a problem. Now, I learned, a landmark study promises to settle the debate.
A DASH of prevention
Since 1972, cutting back on salt has been a cornerstone of the National Blood Pressure Education Program. The advice is based on dozens of studies showing that high levels of salt are linked to hypertension. Most recently, in the February 2000 Journal of Cardiovascular Risk, British hypertension expert Malcolm Law concluded that reducing sodium intake could reduce blood pressure by an average of 10 points (10 mmHg) -- exactly how far mine needs to fall.
Not everyone has been convinced that Law's advice was good. In 1984, analyzing nutrition data gathered from around the country, researchers at the Oregon Health Sciences University in Portland found no evidence that dietary salt was linked to blood pressure. Four years later, results from 7,300 men enrolled in the Scottish Heart Health Study came to the same conclusion. The amount of salt they consumed had no effect on blood pressure.
Systolic pressure is the higher number, which measures the maximum pressure exerted when the heart contracts. Diastolic is the lower number, which measures the pressure when the heart is at rest. Normal systolic pressure is approximately 120 mmHg, and normal diastolic pressure is approximately 70 to 80 mmHg.
