If your blood pressure is high, you need to lower it and keep it under control. Your blood pressure reading has 2 numbers. One or both of these numbers can be too high.

• The top number is called the systolic blood pressure. For most people, this reading is too high if it is 130 or higher.
• The bottom number is called the diastolic blood pressure. For most people, this reading is too high if it is 80 or higher.

The above blood pressure numbers are goals that most experts agree on for most people. For some people age 60 years and above, some health care providers recommend a different blood pressure goal. Some patients may have blood pressure goals lower than these targets, in particular circumstances. Your provider will work with you to create a blood pressure goal that applies to you specifically.

Many medicines can help you control your blood pressure. Your provider will:

• Prescribe the best medicine for you
• Monitor your medicines
• Make changes if needed

Older adults tend to take more medicines and this puts them at greater risk for harmful side effects. One side effect of blood pressure medicine is an increased risk for falls. When treating older adults, blood pressure goals need to be balanced against medicine side effects.

In addition to taking medicine, you can do many things to help control your blood pressure. Some of these include:

• Limit the amount of sodium (salt) you eat. Aim for less than 1,500 mg per day.
• Limit how much alcohol you drink, no more than 1 drink a day for women and 2 a day for men.
• Eat a heart-healthy diet that includes the recommended amounts of potassium and fiber.
• Drink plenty of water.
• Stay at a healthy body weight. Find a weight-loss program, if you need it.
• Exercise regularly. Get at least 40 minutes of moderate to vigorous aerobic exercise at least 3 to 4 days a week aiming for at least 150 minutes per week.
• Reduce stress. Try to avoid things that cause you stress, and try meditation or yoga to de-stress.
• If you smoke, quit. Find a program that will help you stop.

Your provider can help you find programs for losing weight, stopping smoking, and exercising. You can also get a referral to a dietitian from your provider. The dietitian can help you plan a diet that is healthy for you.

Your blood pressure can be measured at many places, including:

• Home
• Your provider's office
• Some local fire stations
• Some pharmacies

Your provider may ask you to keep track of your blood pressure at home. Make sure you get a good quality, well-fitting home device. It is best to have one with a cuff for your arm and a digital readout. Practice with your provider to make sure you are taking your blood pressure correctly.

It is normal for your blood pressure to be different at different times of the day.

It is most often higher when you are at work. It drops slightly when you are at home. It is most often lowest when you are sleeping.

It is normal for your blood pressure to increase suddenly when you wake up. For people with very high blood pressure, this is when they are most at risk for heart attack and stroke.

Your provider will give you a physical exam and check your blood pressure often. With your provider, establish a goal for your blood pressure.

If you monitor your blood pressure at home, keep a written record. Bring the results to your office visit.

Contact your provider if your blood pressure goes well above your normal range.

Also contact your provider if you have any of the following symptoms:

• Severe headache
• Irregular heartbeat or pulse
• Chest pain
• Sweating
• Nausea or vomiting
• Shortness of breath
• Dizziness or lightheadedness
• Pain or tingling in the neck, jaw, shoulder, or arms
• Numbness or weakness in your body
• Fainting
• Trouble seeing
• Confusion
• Difficulty speaking
• Other side effects that you think might be from your medicine or your blood pressure
