Understanding hypertension
High blood pressure is a leading cause of chronic kidney disease
ALMOST HALF of American adults have hypertension. Hypertension, also known as high blood pressure, can constrict and narrow the blood vessels in important organs like the kidneys and heart, causing long-lasting damage.
Hypertension is one of the leading causes of chronic kidney disease. Our kidneys are essential for removing waste and extra fluid from the body. Uncontrolled hypertension causes the blood vessels in the kidneys to constrict, which reduces blood flow and decreases kidney function. This can lead to fluid buildup, which can raise blood pressure even further, creating a dangerous cycle that can lead to kidney failure.
Understanding your blood pressure reading
Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps blood though your body. This is measured in millimeters of mercury, or mmHg. A blood pressure reading includes two numbers. A normal reading is when your top number (systolic) is less than 120 mmHg, and your bottom number (diastolic) is less than 80 mmHg.
Systolic blood pressure in the range of 120-129 is considered elevated. Hypertension is officially diagnosed when the average blood pressure is 130/80 or higher. If your blood pressure reaches 180/120 or above, this may indicate a hypertensive crisis, and you should seek medical attention immediately.
Tips for keeping your blood pressure down
Act now to lower your blood pressure and protect your kidneys. Caring for your kidneys is crucial to prevent long-term damage to the rest of your body. Here are a few expert recommendations that you can put into practice:
Get active. Experts recommend at least 150 minutes of moderate intensity, aerobic activity per week. However, any activity is better than no activity.
Lose weight.
Stop smoking.
Eat healthy and lower your sodium intake. If you have elevated or high blood pressure, reduce your sodium intake to 1,500 mg per day.
Find strategies to help manage stress.
Ask your physician for recommendations on how to tailor a healthy diet and lifestyle that meets all your needs. If these measures aren’t enough, medications may be necessary to lower blood pressure to the normal range.
