Family history Height, hair and eye color runs in families - so can high blood pressure. If your parents or close blood relatives have had HBP, you are more likely to develop it, too. You might also pass that risk factor on to your children. That's why it's important for children as well as adults to have regular blood pressure checks. You can't control heredity, but you can take steps to live a healthy life and lower your other risk factors. Lifestyle choices have allowed many people with a strong family history of HBP to avoid it themselves. Learn about lifestyle changes you can make to prevent HBP.
	Advanced age As we age, we all develop higher risk for high blood pressure and cardiovascular disease. Blood vessels lose flexibility with age which can contribute to increasing pressure throughout the system.
	Gender-related risk patterns A higher percentage of men than women have HBP until 45 years of age. From ages 45 to 54 and 55 to 64, the percentages of men and women with HBP are similar. After that, a much higher percentage of women have HBP than men.
	Lack of physical activity Physical activity is good for your heart and circulatory system. An inactive lifestyle increases the chance of high blood pressure, heart disease, blood vessel disease and stroke. Inactivity also makes it easier to become overweight or obese. Give yourself the gift of improved health and lower blood pressure with regular, moderate-to-vigorous physical activity.
	Poor diet, especially one that includes too much salt To care for our bodies, we all need good nutrition from a variety of food sources. A diet that's high in calories, fats and sugars and low in essential nutrients contributes directly to poor health as well as to obesity. In addition, there are some problems that can happen from eating too much salt. Some people are "salt sensitive," meaning a high-salt (sodium) diet raises their high blood pressure. Salt keeps excess fluid in the body that can add to the burden on the heart. While too much salt can be dangerous, healthy food choices can actually lower blood pressure. Learn about enjoying a heart-healthy diet.
	Overweight and obesity Being overweight increases your chances of developing high blood pressure. A body mass index between 25 and 30 is considered overweight. A body mass index over 30 is considered obese. Excess weight increases the strain on the heart, raises blood cholesterol and triglyceride levels, and lowers HDL (good) cholesterol levels. It can also make diabetes more likely to develop. Losing as little as 10 to 20 pounds can help lower your blood pressure and your heart disease risk. Calculate your body mass index and learn how to manage your weight.
	Drinking too much alcohol Heavy and regular use of alcohol can increase blood pressure dramatically. It can also cause heart failure, lead to stroke and produce irregular heartbeats. Too much alcohol can contribute to high triglycerides, cancer and other diseases, obesity, alcoholism, suicide and accidents. If you drink alcohol, do so in moderation. This means an average of one to two drinks per day for men and one drink per day for women. (A drink is one 12 oz. beer, 4 oz. of wine, 1.5 oz. of 80-proof spirits, or 1 oz. of 100-proof spirits.) If you drink in excess, find out about curbing alcohol intake.

Stress Being in a stressful situation can temporarily increase your blood pressure, but science has not proven that stress causes high blood pressure. Some scientists have noted a relationship between coronary heart disease risk and stress in a person's life, health behaviors and socioeconomic status. How you deal with stress may affect other, established risk factors for high blood pressure or heart disease. For example, people under stress may overeat or eat a less healthy diet, put off physical activity, drink, smoke or misuse drugs.

Smoking and second-hand smoke Smoking temporarily raises blood pressure and increases your risk of damaged arteries. The use of tobacco can be devastating to your health, especially if you're already at risk for high blood pressure. Secondhand smoke - exposure to other people's smoke - increases the risk of heart disease for nonsmokers. Learn how to kick the habit.

	Kidney abnormality, including a tumor on the adrenal gland, which is located on top of the kidneys
	A structural abnormality of the aorta (the large blood vessel leaving the heart) that has existed since birth
	Narrowing of certain arteries

	Women
	African-Americans
	Children (While HBP is most common in adults over age 35, children can develop it, too.)
