Your doctor can help you measure and track your blood pressure to confirm whether it’s too high. You may need to start taking medications if your blood pressure doesn’t improve after one month of following a healthy lifestyle, especially if you’re already at high risk for heart disease. If you’re at lower risk, your doctor may want to follow up in three to six months after you’ve adopted more healthy habits.
The brain requires unobstructed blood flow to nourish its many functions. Very high, sustained blood pressure will eventually cause blood vessels to weaken. Over time these weaken vessels can break, and blood will leak into the brain. The area of the brain that is being fed by these broken vessels start to die, and this will cause a stroke. Additionally, if a blot clot blocks a narrowed artery, blood ceases to flow and a stroke will occur.
Dementia. Dementia is a brain disease resulting in problems with thinking, speaking, reasoning, memory, vision and movement. There are a number of causes of dementia. One cause, vascular dementia, can result from narrowing and blockage of the arteries that supply blood to the brain. It can also result from strokes caused by an interruption of blood flow to the brain. In either case, high blood pressure may be the culprit.
Excessive daytime sleepiness is suggestive of sleep apnea syndrome, but a sleep study is required to diagnose the disorder. Chronic excessive alcohol consumption can also lead to IDH. This may be especially likely if liver damage occurs since angiotensin is usually degraded in the liver. IDH may also be caused by medications, such as oral contraceptives, corticosteroids or nonsteroidal anti-inflammatory drugs like ibuprofen.
Blood pressure is the force of blood pushing against the walls of arteries. When the doctor measures your blood pressure, the results are given in two numbers. The first number, called systolic blood pressure, is the pressure caused by your heart contracting and pushing out blood. The second number, called diastolic blood pressure, is the pressure when your heart relaxes and fills with blood. Your blood pressure reading is usually given as the systolic blood pressure number over the diastolic blood pressure number, such as 138/72. Normal blood pressure for adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. This is stated as 120/80.
If these lifestyle changes don't lower your blood pressure to a safe level, your doctor will also prescribe medicine. You may try several kinds or combinations of medicines before finding a plan that works best for you. Medicine can control your blood pressure, but it can't cure it. You will likely need to take medicine for the rest of your life. Plan with your doctor how to manage your blood pressure.
In order to survive and function properly, your tissues and organs need the oxygenated blood that your circulatory system carries throughout the body. When the heart beats, it creates pressure that pushes blood through a network of tube-shaped blood vessels, which include arteries, veins and capillaries. This pressure — blood pressure — is the result of two forces: The first force (systolic pressure) occurs as blood pumps out of the heart and into the arteries that are part of the circulatory system. The second force (diastolic pressure) is created as the heart rests between heart beats. (These two forces are each represented by numbers in a blood pressure reading.)
Though essential hypertension remains somewhat mysterious, it has been linked to certain risk factors. High blood pressure tends to run in families and is more likely to affect men than women. Age and race also play a role. In the United States, blacks are twice as likely as whites to have high blood pressure, although the gap begins to narrow around age 44. After age 65, black women have the highest incidence of high blood pressure.
National data shows that isolated systolic hypertension is becoming increasingly common among young adults, and study findings raise concern about its effect on heart health. Isolated systolic hypertension is often overlooked in young and middle-aged adults, as most studies on the issue involve older adults, among whom the condition is most common. But current findings suggest that isolated systolic hypertension does, in fact, have a serious impact on the cardiovascular health of young adults. As such, researchers encourage future research to better identify and treat young adults with isolated systolic hypertension who are at greatest risk for heart events.
Essential hypertension is also greatly influenced by diet and lifestyle. The link between salt and high blood pressure is especially compelling. People living on the northern islands of Japan eat more salt per capita than anyone else in the world and have the highest incidence of essential hypertension. By contrast, people who add no salt to their food show virtually no traces of essential hypertension.
Blood pressure is measured with a blood pressure cuff (sphygmomanometer). This may be done using a stethoscope and a cuff and gauge or by an automatic machine. It is a routine part of the physical examination and one of the vital signs often recorded for a patient visit. Other vital signs include pulse rate, respiratory rate (breathing rate), temperature, and weight.
To learn more about isolated systolic hypertension in young adults, researchers analyzed data from the Chicago Heart Association Detection Project in Industry Study, which tracked the health of more than 25,000 young adults for 30 years. After comparing the blood pressure and health outcomes of participants, researchers found that among women, isolated systolic hypertension more than doubled risk of death and increased risk of heart disease by 55%. In men, isolated systolic hypertension increased risk of heart disease by 23% and heart-related death by 28%. Among both men and women, isolated systolic hypertension increased heart risks just as much or more than having higher than normal overall blood pressure.
Your doctor may also use a device called an ophthalmoscope to look at the blood vessels in your eyes. Doctors can see if these vessels have thickened, narrowed, or burst, which may be a sign of high blood pressure. Your doctor will also use a stethoscope to listen to your heart and the sound of blood flowing through your arteries. In some cases, a chest x-ray and electrocardiogram may be needed.
Diastolic pressure is the force exerted by the blood on the walls of arteries as it flows through these blood vessels between heartbeats. In IDH, the diastolic pressure is generally elevated because tiny arteries, called arterioles, in the body are narrower than usual. This compresses the blood flowing through the arterioles, thus raising the pressure.
Hypertension, the medical term for high blood pressure, is known as "the silent killer." More than 80 million Americans (33%) have high blood pressure, and as many as 16 million of them do not even know they have the condition. If left untreated, high blood pressure greatly increases your risk for heart attack and stroke. Hypertension is projected to increase about 8 percent between 2013 and 2030.
