DIFFERENCE OF BLOOD PRESSURE IN RIGHT AND LEFT ARMS COULD SIGNAL TROUBLE.
The next time you have your blood pressure checked, don’t be surprised if your doctor, nurse, or other health-care provider measures it twice—once in each arm. A significant difference in the pressure recorded in the right and left arms can signal circulatory problems that may lead to stroke, peripheral artery disease, or other cardiovascular problems.
British researchers looked at the results of 20 studies in which blood pressure was measured in both arms. People with an arm-to-arm difference of 15 points or more were twice as likely to have peripheral artery disease—essentially cholesterol-clogged arteries in the arms, legs, or other non-heart parts of the body. Peripheral artery disease affects at least 12 million Americans, more than heart disease and stroke combined. It kills some, maims others, and makes life painful for countless more.
A blood pressure difference of 10 to 15 points or more between arms also boosted the chances of having a stroke or dying from cardiovascular disease.
Blood pressure generally is higher in the winter and lower in the summer. That's because low temperatures cause your blood vessels to narrow — which increases blood pressure because more pressure is needed to force blood through your narrowed veins and arteries.
In addition to cold weather, blood pressure may also be affected by a sudden change in weather patterns, such as a weather front or a storm. Your body — and blood vessels — may react to abrupt changes in humidity, atmospheric pressure, cloud cover or wind in much the same way it reacts to cold. These weather-related variations in blood pressure are more common in people age 65 and older.
Other seasonal causes of higher blood pressure include weight gain and decreased physical activity in winter. If you have high blood pressure already, continue to monitor your blood pressure readings as the seasons change and talk to your doctor. Your doctor may recommend changing the dose of your blood pressure medication or switching to another medication.
When I came to U.S.A., my Cardiologist told me that in cold weather I may have to increase the Dose of my B.P. Medicine.
B.P. should always to be taken when you are relaxed and preferably lying down. more
