Blood pressure: what the numbers mean and what you can do today

High blood pressure often shows no symptoms but quietly damages your heart, kidneys, and brain. Knowing your numbers and what to do about them cuts risk fast. Below you’ll find plain facts, easy actions you can start now, and safety tips about medicines people commonly use — including warnings about diuretics like spironolactone.

How to check and track your blood pressure

Buy a validated home monitor (upper-arm models are best). Sit quietly for 5 minutes, feet flat, back supported, and take two readings one minute apart. Write down the date, time, and both numbers. Normal is under 120/80 mmHg. Elevated is 120–129/<80. Hypertension starts at 130/80. If readings are consistently high, talk to your doctor.

Bring your log to appointments. Home readings help doctors decide if lifestyle changes or medicine are needed. If your reading ever hits 180/120 or you have chest pain, shortness of breath, or weakness, get emergency care right away.

Simple steps to lower blood pressure & safety notes

Small changes add up. Cut back on salt (aim for under 2,300 mg daily), move more (30 minutes most days), lose even 5% of body weight if you’re overweight, drink less alcohol, and stop smoking. Eat more vegetables, whole grains, and lean protein. If you already have diabetes or heart disease, your doctor may want lower targets.

Many people need medicine. Common classes are ACE inhibitors, ARBs, calcium channel blockers, and diuretics. Diuretics include loop diuretics (like furosemide/Lasix) and potassium-sparing ones (like spironolactone). Potassium-sparing diuretics can raise blood potassium — mixing them with alcohol or other drugs can cause dangerous spikes. We cover that risk in our article “Potassium Spikes: Unmasking Danger When Mixing Alcohol and Spironolactone.”

Watch for side effects: dizziness, lightheadedness, swelling, cough, or sudden weight gain. Don’t stop medicines suddenly — some should be tapered. Always tell your doctor about other drugs and supplements you take. For example, potassium supplements plus potassium-sparing diuretics can be risky.

If your blood pressure stays high despite lifestyle changes and one medicine, your doctor may add a second drug or run tests to find an underlying cause. Regular checks, honest talk with your provider, and safe medication choices are the fastest way to take control.
