If you think your blood pressure is normal, you may want to double-check with your doctor. According to new guidelines, blood pressure of 120/80 mmHg, which was until recently seen as within a healthy range, is now classified as elevated.
Scientists at the University of California, San Diego (UCSD) found that people under the age of 65 who were diagnosed with a condition called “prehypertension” had a 68 percent increased risk of suffering a stroke compared to those with normal readings.
Prehypertension is defined by the National Institutes of Health (NIH) as a systolic pressure (upper number) of 120 to 139 mmHg and a diastolic pressure (lower number) of 80 to 89. Higher readings than 140/90 are considered to be hypertension. Ideally, the normal range should be well below the prehypertension threshold.
When blood pressure rises, the heart has to work harder. If blood pressure remains chronically elevated, the risk of cardiovascular disease increases, which can eventually lead to heart attack, stroke or heart failure.
A primary risk factor is obesity. The greater the body mass, the more blood is needed to transport oxygen and nutrients. The higher volume of blood circulating through the blood vessels puts ever more force on the artery walls.
There are other causes as well. Atherosclerosis, the buildup of fatty deposits in the arteries, is quite common. Other contributing conditions are sleep apnea, kidney disease, thyroid disease and adrenal disease.
Poor diet – and lifestyle choices are most often (at least in part) responsible for high blood pressure to occur. But even some medications, including birth control pills, cold remedies, painkillers and other prescription drugs can play a role.
So can recreational drugs like cocaine and amphetamines. There is no cure for high blood pressure, only treatment through medication and lifestyle measures like diet and exercise.
Prehypertension should be seen as a warning sign, according to Dr. Bruce Ovbiagele, a professor at UCSD and lead author of the study that lead to the revised guidelines. “This doesn’t mean that people with prehypertension should start taking anti-hypertensive drugs. Instead, they should modify their lifestyle, maintain an ideal weight and lower their sodium intake.”
The worst you can do is to ignore the numbers, said Dr. Ovbiagele. “You shouldn’t be deceived because nothing seems to be going on.”
Because there are no specific symptoms for prehypertension or hypertension, people tend to think they can live with the condition.
Nothing could be further from the truth. If you are overweight, even moderately, shed the extra pounds as soon as possible. Exercise regularly.
Nothing is better for your blood pressure and your heart than a rigorous workout several times a week (consult with your doctor if you already have elevated blood pressure and don’t currently exercise). Eat plenty of fruits, vegetables, whole grains, fish and low-fat dairy products. Avoid foods that are high in sodium like processed and packaged food items. Eat foods that are low-fat, low-cholesterol and free of trans fats and other unhealthy ingredients. Cut back on meat, especially red meat. Drink alcohol in only moderation, preferably red wine. Last but not least, manage your stress and get enough sleep.
