High Blood Pressure and Weight

The short version

• High blood pressure usually has no symptoms, so measuring is the only way to know.
• Current US guidelines define hypertension as 130/80 mm Hg or higher.
• Weight loss, the DASH diet, less sodium, exercise and less alcohol can each lower your pressure, and they add up.
• Never stop your medication on your own. A reading above 180/120 with symptoms is an emergency.

The numbers

Most adults are advised to aim for under 130/80. Your own target depends on your health and overall risk.

What lowers it

Effects vary a lot by person, but here are rough, commonly cited ranges for people with high blood pressure:

These add up, although not perfectly. Start with the ones you think you can keep doing.

Where to start

1. Try the DASH diet. It was designed specifically for this.
2. Cut sodium. Especially from restaurant food, canned soups and deli meats.
3. Get moving. A daily brisk walk is enough to help. See the walking plan.
4. Drink less alcohol. See alcohol.
5. Treat sleep apnea if you have it. See sleep apnea.
6. Check for other causes. NSAID pain relievers (such as ibuprofen), decongestants, stimulants and some supplements can all raise your pressure.

Measure at home

Home readings give a better picture than the occasional office visit:

• Use a validated upper-arm cuff that fits your arm. A cuff that's too small can give falsely high readings. Ask your pharmacy or clinic for help finding the right size.
• Sit quietly for 5 minutes first, with your back supported, feet flat and arm at heart level.
• Skip caffeine, exercise and smoking for 30 minutes before.
• Take 2 readings a minute apart, in the morning and evening, and keep a log.

Medication

Many people need medication, and that's okay. It's not a sign you've failed. The American Heart Association says stage 2 calls for medication along with lifestyle changes, and some people at stage 1 need it too. Lifestyle changes may let you reduce your dose over time, but only with your clinician's help. As you lose weight, your pressure may fall enough that your dose needs to come down. If you feel dizzy when standing up, let your clinician know.
