The best evidence indicates that high blood pressure does not cause headaches or nosebleeds, except in the case of hypertensive crisis, a medical emergency when blood pressure is 180/120 mm Hg or higher. If your blood pressure is unusually high AND you have headache or nosebleed and are feeling unwell, wait five minutes and retest. If your reading remains at 180/120 mm Hg or higher, call 9-1-1.

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
In short, everyone. The motivation behind the change was to make people healthier. With more sensitive guidelines, we are able to get in control of our blood pressure sooner and improve heart health before reaching levels that could cause more serious health problems. For some, the changing guidelines may result in antihypertensive (blood pressure lowering) medication, along with lifestyle management, but that will not be the case for everyone.
If you are in this 130/80 range, reducing your blood pressure can help protect you from heart attack, stroke, kidney disease, eye disease, and even cognitive decline. The goal of the new guidelines is to encourage you to treat your high blood pressure seriously and to take action to bring it down, primarily using lifestyle interventions. "It is well documented that lifestyle changes can lower blood pressure as much as pills can, and sometimes even more," says Dr. Fisher.
The causes are most often some combination of clogged “pipes” and excessive salt in the diet. Lifestyle changes, such as appropriate diet and exercise, are among the most effective treatment strategies for high blood pressure. Relaxation, meditation, and otherwise “taking it easy” are not effective solutions, as valuable as such strategies may be for your psychological well-being.
Changes in blood vessel structure. Blood vessels have layers of the proteins elastin and collagen. Elastin is what makes blood vessels flexible. Collagen, which is stiffer, gives vessels structure. With age, elastin breaks down. Even the elastin that remains becomes less elastic. Meanwhile, collagen deposits in the vessels increase. As a result, blood vessels grow thicker and bend less easily over time. These changes may lead to higher systolic blood pressure.
If you suddenly find yourself with high blood pressure (hypertension) under the new guidelines from the American Heart Association and the American College of Cardiology, you might be wondering what to do. The guidelines, which were released in November, lowered the definition for high blood pressure to 130/80 from 140/90 millimeters of mercury (mm Hg), meaning more women now meet the criteria for stage 1 hypertension.
Because of the need for emergency care, it is important to recognize the early signs of malignant hypertension. The first giveaway is blood pressure of 180/120. You might have bleeding in the eyes due to rupture of the small blood vessels. Other malignant hypertension symptoms can include chest pain, dizziness, a headache, numbness in your extremities, and confusion.
Magnesium: Magnesium, which is present in nuts, seeds, avocado, and green leafy vegetables, has also been proposed as a natural way to reduce blood pressure. Supplements are also available in pill form. Studies show that higher levels of magnesium are associated with lower blood pressure, but it is still not completely clear whether there is a cause-and-effect relationship.

Americans eat far too much dietary sodium, up to three times the recommended total amount, which is 1,500 milligrams (mg) daily for individuals with high blood pressure, says Dr. Fisher. It doesn't take much sodium to reach that 1,500-mg daily cap — just 3/4 of a teaspoon of salt. There's half of that amount of sodium in one Egg McMuffin breakfast sandwich. Weed out high-sodium foods by reading labels carefully. "It is very difficult to lower dietary sodium without reading labels, unless you prepare all of your own food," says Dr. Fisher. Beware in particular of what the American Heart Association has dubbed the "salty six," common foods where high amounts of sodium may be lurking:
Sodium (salt) sensitivity: Some people have high sensitivity to sodium (salt), and their blood pressure increases if they use salt. Reducing sodium intake tends to lower their blood pressure. Americans consume 10-15 times more sodium than they need. Fast foods and processed foods contain particularly high amounts of sodium. Many over-the-counter medicines also contain large amounts of sodium. Read food labels and learn about salt content in foods and other products as a healthy first step to reducing salt intake. Fast food restaurants also make the salt and calorie content of their food available to consumers at their restaurants,
