First, your doctor will make sure of the diagnosis by checking your blood pressure again. Blood pressure goes up and down, even in people who don't have hypertension. For example, a painful injury or an illness with fever can cause your blood pressure to go up for awhile. You only have true hypertension if your blood pressure is elevated when you are resting comfortably and haven't done anything that would make your blood pressure high (e.g., smoking cigarettes, or drinking coffee or a caffeinated soft drink before your exam). Next, your doctor will take your medical history and give you a physical exam to see if a specific cause for hypertension can be found. Your doctor will check to see if hypertension has damaged blood vessels in your brain, heart, kidneys or other organs. Your doctor will also check other risk factors, including smoking, high cholesterol levels, diabetes, and your family history of heart disease and stroke. Your doctor will then decide on your treatment. This will include the lifestyle changes listed on the previous page, which are also useful in treating hypertension. Then, if your blood pressure is very high (above 160/100), or if you have one or more of the risk factors listed on the previous page, or if you have organ damage, including coronary disease, an enlarged heart, stroke or transient ischemic attacks (mini-strokes), kidney disease or peripheral arterial disease, your doctor will prescribe antihypertensive medicine and treat you for the other risk factors. More than 80 different medicines are available to treat high blood pressure. More than 90 percent of patients with hypertension get good results from antihypertensive medicines if they follow their doctor's instructions. Your treatment will be more successful if you follow these guidelines: Work with your doctor to establish treatment goals. Involve your family in your treatment program—improve your family's diet and exercise. This is helpful for everyone and may prevent other family members from developing hypertension. Measure your blood pressure at home and keep a daily record—this will help your doctor keep track of your progress. Be sure to take your medicine every day. If you don't think you're making progress in controlling your hypertension, talk with your doctor—communication is a key to success. Keep your doctor appointments—even if your blood pressure is under control, see your doctor every three to six months.
