Hypertension

What is Hypertension?

Hypertension is the medical term for high blood pressure. It means your blood is pushing too hard against your artery walls as your heart pumps. Blood pressure is measured with two numbers. The top number is systolic pressure, which measures force during a heartbeat. The bottom number is diastolic pressure, which measures force between beats.

Normal blood pressure is below 120/80 mmHg. Hypertension is diagnosed when readings consistently reach 130/80 mmHg or higher. Your blood vessels and organs face extra strain when pressure stays elevated. Over months and years, this can damage your heart, kidneys, brain, and blood vessels.

Most people with high blood pressure feel completely normal. The condition rarely causes symptoms until serious damage has occurred. This is why doctors call hypertension the silent killer. Regular monitoring helps you catch problems early, before they threaten your long-term health.

Most people with hypertension have no symptoms at all, especially in the early stages. High blood pressure can damage your organs silently for years before you notice any problems. This is why regular blood pressure checks and blood testing are essential for protecting your health.

Causes and risk factors

Hypertension develops when your blood vessels become stiff or narrow over time. For most people, the cause is a combination of lifestyle and genetic factors. Eating too much sodium causes your body to retain fluid, which increases pressure. Being overweight or inactive makes your heart work harder. Chronic stress keeps your body in a high-alert state that elevates pressure. Smoking damages blood vessel walls and raises your risk significantly.

Age increases your risk as arteries naturally stiffen over time. Family history matters, as high blood pressure often runs in families. Certain health conditions raise your risk, including diabetes, kidney disease, and sleep apnea. Some medications and supplements can elevate blood pressure. Drinking too much alcohol or not getting enough potassium in your diet also contribute to high readings.

How it's diagnosed

Doctors diagnose hypertension by taking multiple blood pressure readings over time. A single high reading does not confirm the condition. You may need readings at different times of day or on different days. Some people use home blood pressure monitors to track their numbers between visits.

Blood tests help identify kidney damage and other complications from high blood pressure. Rite Aid offers add-on testing to monitor biomarkers that show how hypertension affects your body. Tests like eGFR measure kidney function, which can decline from long-term high pressure. Albumin/creatinine ratio and protein/creatinine ratio detect early kidney damage. Biomarkers like BNP help assess heart strain, while Lipoprotein(a) and other markers evaluate cardiovascular risk. Testing is available at over 2,000 Quest Diagnostics locations nationwide.

Treatment options

Reduce sodium intake to less than 2,300 mg per day, or ideally 1,500 mg
Eat more potassium-rich foods like leafy greens, bananas, and sweet potatoes
Maintain a healthy weight through balanced nutrition
Exercise for at least 150 minutes per week with moderate activity
Limit alcohol to no more than 1 drink per day for women, 2 for men
Quit smoking and avoid secondhand smoke
Manage stress through meditation, deep breathing, or yoga
Get 7 to 9 hours of quality sleep each night
Medications like ACE inhibitors, ARBs, diuretics, or calcium channel blockers when lifestyle changes are not enough
Regular monitoring of blood pressure and kidney function with your doctor

Frequently asked questions

Blood pressure of 130/80 mmHg or higher is considered hypertension. The first number measures pressure during a heartbeat, while the second measures pressure between beats. Readings between 120/80 and 129/79 are considered elevated and mean you should take steps to prevent full hypertension. Your doctor may diagnose hypertension after multiple high readings on different days.

Yes, most people with high blood pressure feel completely fine. Hypertension is called the silent killer because it rarely causes noticeable symptoms until serious damage occurs. You might live with dangerously high blood pressure for years without knowing it. This is why regular blood pressure checks are essential, even when you feel healthy.

Tests like eGFR measure how well your kidneys filter waste, which declines when high blood pressure damages them. Albumin/creatinine ratio and protein/creatinine ratio detect protein leaking into urine, an early sign of kidney damage. BNP shows if your heart is under strain. These biomarkers help catch complications before they become severe.

Many people see improvements within 1 to 2 weeks of reducing sodium and starting exercise. Losing even 5 to 10 pounds can significantly lower your numbers. More substantial changes may take 1 to 3 months to fully show in your readings. Consistency matters more than perfection when it comes to lifestyle approaches.

Not necessarily. Some people successfully manage hypertension with lifestyle changes alone, especially if caught early. Others need medication but can reduce doses or stop entirely after sustained improvements in diet, weight, and exercise. Your doctor will monitor your progress and adjust treatment as needed. Never stop medication without medical guidance, as sudden changes can be dangerous.

Temporary stress spikes your blood pressure in the moment, but the reading usually returns to normal. Chronic, unmanaged stress can contribute to sustained hypertension over time. Stress often leads to unhealthy coping behaviors like overeating, drinking, or smoking that directly raise blood pressure. Managing stress through healthy habits helps protect your cardiovascular system.

DASH stands for Dietary Approaches to Stop Hypertension. This eating pattern focuses on vegetables, fruits, whole grains, lean proteins, and low-fat dairy. It limits sodium, red meat, sweets, and sugary drinks. Studies show DASH can lower blood pressure as effectively as some medications when followed consistently.

If you have hypertension, check your blood pressure at home at least a few times per week. Take readings at the same time each day for consistency. People with well-controlled blood pressure may only need monthly checks. Your doctor will recommend a schedule based on your specific situation and treatment plan.

Yes, hypertension is increasingly common in younger adults and even children. Obesity, poor diet, lack of exercise, and family history can cause high blood pressure at any age. Young people often assume they are too healthy to have the condition and miss early warning signs. Anyone over age 18 should have their blood pressure checked regularly.

Primary hypertension has no single identifiable cause and develops gradually over years from lifestyle and genetic factors. This type accounts for about 90 to 95 percent of all cases. Secondary hypertension is caused by an underlying condition like kidney disease, hormonal disorders, or certain medications. It often appears suddenly and produces higher readings than primary hypertension.
