What Is Hypertension? Symptoms, Causes, Treatment, and Medications
Hypertension, or high blood pressure, is blood pressure that stays at or above 130/80 mm Hg. It usually causes no symptoms but raises the risk of heart disease, stroke, and kidney damage. It is treated with lifestyle changes and medications such as ACE inhibitors, ARBs, calcium channel blockers, and thiazide diuretics.
Key Highlights
- Hypertension (high blood pressure) is blood pressure that is consistently at or above 130/80 mm Hg, according to the CDC and the 2025 ACC/AHA guideline.
- High blood pressure usually has no warning signs, so measuring your blood pressure is the only way to know you have it.
- Left untreated, hypertension can damage the heart, brain, kidneys, and eyes and raise the risk of heart attack and stroke.
- First-line medications include ACE inhibitors (lisinopril), ARBs (losartan), calcium channel blockers (amlodipine), and thiazide diuretics (hydrochlorothiazide, chlorthalidone).
- Lifestyle steps such as a lower-sodium diet, regular activity, healthy weight, limited alcohol, and not smoking are an important part of treatment.
- PriceMyMeds discount coupons can help reduce the cost of blood pressure medications at participating pharmacies, with no insurance required.
What Is Hypertension?
Hypertension, commonly called high blood pressure, is the force of blood pushing against your artery walls staying higher than normal over time. Normal blood pressure is less than 120/80 mm Hg. High blood pressure is consistently at or above 130/80 mm Hg, based on guidelines from the American College of Cardiology (ACC) and the American Heart Association (AHA).
Because it usually causes no symptoms, high blood pressure is sometimes called a silent condition. Over time the extra pressure can damage arteries and organs, which is why regular measurement and treatment matter. About half of American adults have high blood pressure.
Key Facts:
- Generic names: lisinopril, losartan, amlodipine, hydrochlorothiazide, chlorthalidone, metoprolol
- Drug classes: ACE inhibitors, ARBs, calcium channel blockers, thiazide diuretics, beta-blockers
- FDA approvals: all four first-line classes are FDA approved for hypertension; lisinopril is an ACE inhibitor used for high blood pressure in adults and children age 6 and older
- Typical cost: many generic blood pressure pills cost about $4-$25 per month; PriceMyMeds coupons may help lower the price
- Common uses: lowering blood pressure to reduce the risk of heart attack, stroke, and kidney disease
Hypertension vs. Elevated Blood Pressure: Understanding the Difference
Blood pressure is grouped into categories. Normal is less than 120/80 mm Hg. Elevated blood pressure is a systolic reading of 120-129 mm Hg with a diastolic below 80 mm Hg. Hypertension is diagnosed when readings are consistently at or above 130/80 mm Hg. Knowing your category helps you and your provider decide whether lifestyle changes alone or added medication are needed.

Understanding Hypertension: Causes, Symptoms, Diagnosis, Treatment, and Prevention
1.What Are the Causes of Hypertension?
Most high blood pressure develops gradually over years and often has no single cause. This is called primary (essential) hypertension. Less often, another condition or medication raises blood pressure, which is called secondary hypertension.
Lifestyle and Common Risk Factors
- A diet high in sodium (salt) and low in potassium
- Not getting enough regular physical activity
- Overweight or obesity
- Drinking too much alcohol
- Tobacco use
- Ongoing stress, anxiety, or poor sleep
Health Conditions That Can Raise Blood Pressure
- Diabetes
- Chronic kidney disease
- Obstructive sleep apnea
- Thyroid or adrenal gland disorders
Other Factors
- Increasing age
- Family history of high blood pressure
- Some medications, such as certain cold remedies and NSAIDs
- Pregnancy (high blood pressure can develop during pregnancy)
You can control many of these risk factors with lifestyle changes and, when needed, medication.
2.What Are the Symptoms of Hypertension?
High blood pressure usually has no warning signs or symptoms, and many people do not know they have it. Measuring your blood pressure is the only reliable way to find out.
Because there are usually no symptoms:
- Most people feel completely normal even when blood pressure is high
- Damage to the heart, brain, kidneys, and eyes can build up silently over time
- Routine blood pressure checks are the key to early detection
Very high blood pressure (a hypertensive crisis) can sometimes cause severe headache, chest pain, shortness of breath, or vision changes and needs emergency care.
How Long Does Hypertension Last?
For most people, hypertension is a long-term (chronic) condition that is managed rather than cured. With lifestyle changes and medication, blood pressure can be brought into a healthy range and kept there. Some people with mild high blood pressure can lower it into a healthy range with lifestyle changes alone, while many others need ongoing medication.
3.How Is Hypertension Diagnosed?
Hypertension is diagnosed by measuring your blood pressure, usually on more than one visit. A reading has two numbers: systolic (top) over diastolic (bottom), measured in mm Hg.
Your provider may ask:
- Do you have a family history of high blood pressure or heart disease?
- What is your diet, activity level, and alcohol and tobacco use?
- Do you have diabetes, kidney disease, or sleep apnea?
- What medications and supplements do you take?
Blood pressure categories (ACC/AHA):
- Normal: less than 120/80 mm Hg
- Elevated: systolic 120-129 and diastolic less than 80 mm Hg
- High blood pressure: 130/80 mm Hg or higher
Additional tests may include:
- Home or 24-hour ambulatory blood pressure monitoring
- Blood and urine tests to check kidney function, blood sugar, and cholesterol
- An electrocardiogram (ECG) to check the heart
4.How Is Hypertension Treated?
Treatment combines healthy lifestyle changes with medication when needed. For most adults, the goal is a blood pressure below 130/80 mm Hg.
Lifestyle Changes
- Eat a heart-healthy diet lower in sodium (such as the DASH diet)
- Be physically active, aiming for about 30 minutes a day most days
- Reach and keep a healthy weight
- Limit alcohol and do not smoke
- Manage stress and get enough sleep
2. First-Line Medications
The 2025 ACC/AHA guideline lists four first-line drug classes:
- ACE inhibitors, such as lisinopril, enalapril, and ramipril
- Angiotensin II receptor blockers (ARBs), such as losartan, valsartan, and telmisartan
- Calcium channel blockers, such as amlodipine
- Thiazide and thiazide-like diuretics, such as hydrochlorothiazide and chlorthalidone
Combination Therapy
Many people need two or more medications from different classes to reach their goal. Combining an ACE inhibitor or ARB with a calcium channel blocker or thiazide diuretic is a common approach, sometimes as a single combination pill to make it easier to take.
Other Medications
Beta-blockers, such as metoprolol and carvedilol, and other drugs may be added, especially when there are other heart conditions. Your provider chooses medications based on your overall health and any other conditions you have.
5.What Are the Complications of Hypertension?
Uncontrolled high blood pressure can damage many organs over time, which is why treatment is so important.
Possible complications include:
- Heart attack and heart disease
- Heart failure
- Stroke
- Chronic kidney disease or kidney failure
- Vision loss from damage to the eyes
- Cognitive decline and dementia, especially when high blood pressure begins in midlife
- Peripheral artery disease
- Pregnancy-related complications
The higher your blood pressure and the longer it goes untreated, the greater the risk. The good news is that lowering blood pressure reduces the risk of these serious problems.
6.How Can Hypertension Be Prevented?
Many cases of high blood pressure can be prevented or delayed with healthy habits, and the same steps help control it once it develops.
Prevention steps include:
- Eat a diet rich in vegetables, fruits, and whole grains and lower in sodium
- Get regular physical activity, about 30 minutes a day, 5 days a week
- Reach and maintain a healthy weight
- Limit alcohol
- Do not smoke
- Manage stress
- Check your blood pressure regularly so problems are caught early
Even small, steady changes can help keep your blood pressure in a healthy range and protect your heart, brain, and kidneys.
7.When to See a Doctor for Hypertension
Because high blood pressure has no symptoms, everyone should have their blood pressure checked regularly. See your provider if a reading is high or if you have been told you have high blood pressure that is not under control.
Talk with your health care team if:
- Your home readings are consistently 130/80 mm Hg or higher
- You have side effects from your blood pressure medication
- You have diabetes, kidney disease, or heart disease along with high blood pressure
Call 911 or seek emergency care right away for a very high reading (often 180/120 mm Hg or higher) along with chest pain, shortness of breath, severe headache, weakness or numbness, trouble speaking, or vision changes. These may be signs of a hypertensive crisis, heart attack, or stroke.
8.OTC vs. Prescription Hypertension Medications: When Do You Need a Prescription?
There are no over-the-counter medications that treat high blood pressure. All blood pressure medicines require a prescription and follow-up with a provider.
Over-the-counter products that support blood pressure control indirectly:
- Low-sodium food choices and salt substitutes (ask your provider first, since some are high in potassium)
- A home blood pressure monitor to track your numbers
Prescription required for:
- ACE inhibitors - lisinopril, enalapril, ramipril
- ARBs - losartan, valsartan, telmisartan
- Calcium channel blockers - amlodipine
- Thiazide and thiazide-like diuretics - hydrochlorothiazide, chlorthalidone
- Beta-blockers - metoprolol, carvedilol
Important: Some over-the-counter products, such as certain cold and pain medicines (NSAIDs and decongestants), can raise blood pressure. Check with your pharmacist or provider before using them if you have hypertension.

The Bottom Line
Hypertension, or high blood pressure, is a common condition defined as readings consistently at or above 130/80 mm Hg. It usually causes no symptoms but, over time, raises the risk of heart attack, stroke, kidney disease, and other serious problems, which is why regular blood pressure checks matter.
Treatment combines lifestyle changes with medication when needed. First-line options include ACE inhibitors such as lisinopril, ARBs such as losartan, calcium channel blockers such as amlodipine, and thiazide diuretics such as hydrochlorothiazide and chlorthalidone. Many people need more than one medication to reach a healthy blood pressure.
