For obese people or people with family history of high blood pressure, you need to watch your blood pressure. Your total blood pressure reading is determined by measuring your systolic and diastolic blood pressures. Systolic BP, the top number, measures the force your heart exerts on the walls of your arteries each time it beats. Diastolic BP, the bottom number, measures the force your heart exerts on the walls of your arteries in between beats. Below is a blood pressure chart by age.
Your blood pressure is said to be “high” when either your systolic blood pressure is 140 or above, or your diastolic blood pressure is 90 or above, or both. So if your blood pressure is found to be 142/88 (systolic = 142, diastolic = 88), you are diagnosed as having high blood pressure, according to current definitions. The same would be true if your blood pressure was found to be 135/92, or 152/95. In each case, either the systolic is high, or the diastolic is high, or both. Any of these findings result in a diagnosis of high blood pressure.
Another important step is to lose weight and maintain a healthy weight. Being overweight elevates your risk for high blood pressure and many other diseases and conditions. Losing just 5 percent of your body weight can have a significant positive impact on your blood pressure. Studies have shown that the combination of exercising and losing weight improves blood pressure numbers even more than either one alone. It may seem daunting to lose weight, but it is possible. Talk to your doctor about how other people have done it. And consider seeing a weight loss counselor too. You can do this! And after only a few pounds of healthy weight loss, you should start seeing your blood pressure numbers drop.
Women who are taking ACE inhibitors or ARBs for high blood pressure should not become pregnant while on this class of drugs. If you're taking an ACE inhibitor or an ARB and think you might be pregnant, see your doctor immediately. These drugs have been shown to be dangerous to both mother and baby during pregnancy. They can cause low blood pressure, severe kidney failure, excess potassium (hyperkalemia) and even death of the newborn.
Quitting smoking. Visit Smoking and Your Heart and the National Heart, Lung, and Blood Institute’s Your Guide to a Healthy Heart [PDF – 2MB]. Although these resources focus on heart health, they include basic information about how to quit smoking. For free help and support to quit smoking, you can call the National Cancer Institute’s Smoking Quitline at 1-877-44U-QUIT (1-877-448-7848).
Hypertension does not usually cause any noticeable symptoms. When it does, you might experience dizziness, shortness of breath, headaches, and nosebleeds, which could indicate that your blood pressure is rising. Complications such as heart disease, stroke, and kidney failure can occur if long-term hypertension is not adequately treated. A hypertensive emergency, which is an uncommon and dangerous event, may cause blurry vision, nausea, chest pain and anxiety.
Some research on watermelon extract and high blood pressure suggests the amino acid citrulline found in the fruit may help manage high blood pressure. One study found those who took watermelon extract showed reduced blood pressure specifically in the ankles and arm arteries. Other studies on mice also show watermelon’s positive effect. Although more research is needed to determine the specifics, eating fruit like watermelon isn’t going to hurt.
Do not attempt to lower extremely elevated blood pressure in yourself or someone else. While the goal is to reduce blood pressure before additional complications develop, blood pressure should be reduced over the course of hours to days, depending on severity. It is important not to lower blood pressure too quickly, because rapid blood pressure reductions can cut off the supply of blood to the brain, leading to brain damage or death.
Changes in blood vessel function. The lining of blood vessels sustains more damage over time. This may be caused by oxidative stress or DNA damage, among other factors. With age, levels of the hormone angiotensin also rise, triggering inflammation in blood vessels. At the same time, vessels slowly lose the ability to release substances that protect or repair the lining. When the blood vessel lining does not work as well, higher diastolic blood pressures can result.
This study is assessing whether a low-sodium and low-calorie eating pattern, along with aerobic exercise, can improve blood pressure in patients who do not respond to high blood pressure medicines. To participate you must be at least 35 years and have high blood pressure that does not respond to medicines. Please note that this study is in Durham, North Carolina.
Elevated blood pressures in the medical setting may not necessarily reflect the individuals real status. "White coat hypertension" describes a patient whose blood pressure is elevated because of the stress of the visit to the doctor or other healthcare professional, and the worry that their blood pressure might be elevated. Repeated blood pressure checks at the doctor's office or the use of a home blood pressure monitoring device may be used to confirm that you have high blood pressure.
