Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Blood Pressure Measurement
Positive result: Blood pressure is measured using a sphygmomanometer, typically after the patient has rested for at least five minutes, with their arm supported at heart level. It is the primary method for diagnosing hypertension, requiring multiple readings over time.
Positive results indicate presence of the condition
Additional tests
Ambulatory Blood Pressure Monitoring (ABPM)
Positive results indicate presence of the condition
Home Blood Pressure Monitoring
Positive results indicate presence of the condition
Urine Test for Microalbuminuria
Positive results indicate presence of the condition
Electrocardiogram (ECG)
Positive results indicate presence of the condition
Echocardiogram
Positive results indicate presence of the condition
Funduscopy
Positive results indicate presence of the condition
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Thiazide Diuretics
Thiazide diuretics are often used as initial therapy for hypertension in patients without compelling indications for other drug classes.
Not for: Allergy to sulfonamides, Gout, Severe kidney impairment
Side effects: Hypokalemia, Hyperuricemia, Hyperglycemia
Angiotensin-Converting Enzyme (ACE) Inhibitors
ACE inhibitors are a common choice for initial therapy in many patients with hypertension.
Not for: Pregnancy, History of angioedema, Bilateral renal artery stenosis
Side effects: Cough, Hypotension, Hyperkalemia, Renal impairment
Additional treatment options
Angiotensin Receptor Blockers (ARBs)
ARBs are used as an alternative to ACE inhibitors for patients who cannot tolerate ACE inhibitors.
medicationCalcium Channel Blockers (CCBs)
CCBs are effective in treating hypertension and may be preferred in patients with isolated systolic hypertension.
medicationBeta Blockers
Beta blockers are considered for hypertension, particularly in younger patients.
medicationAlpha Blockers
Alpha blockers may be used for hypertension, often as part of combination therapy.
medicationCentral Acting Agents
Central acting agents are used in patients with hypertension, often to enhance other therapies.
medicationVasodilators
Vasodilators are used less commonly as monotherapy because of their side effects.
medicationLifestyle Modifications
Lifestyle modifications are an essential component of hypertension treatment.
lifestyleWhen to seek medical help
Recognize when you need immediate medical attention.
Call emergency services (911) immediately
Severe headache with confusion or changes in vision
Seek emergency medical attention, Do not wait for symptoms to subside
Severe chest pain
Call emergency services immediately, Do not attempt to drive yourself to the hospital
Frequently asked questions
Common questions about this topic.
What exactly is high blood pressure?
High blood pressure, also known as hypertension, occurs when the force of blood pushing against your artery walls is consistently too high. This can damage your arteries and increase your risk for heart disease, stroke, and other health problems.
Understanding HypertensionHow can I know if I have high blood pressure?
Many people with high blood pressure don't have any symptoms. The only way to know is to have your blood pressure checked regularly by a healthcare provider. They will use an inflatable cuff and measure your blood pressure readings.
DiagnosisWhat causes high blood pressure?
The exact cause is often unknown, but several factors contribute to it, including smoking, an unhealthy diet, lack of physical activity, too much salt in the diet, high stress, and unhealthy levels of body weight.
Causes and Risk FactorsCan high blood pressure be treated?
Yes, high blood pressure can be treated. Treatment often includes lifestyle changes such as eating a healthy diet, exercising regularly, maintaining a healthy weight, and reducing sodium intake. Medications may also be prescribed.
TreatmentWhat are the best foods for someone with high blood pressure?
Foods that are high in potassium, calcium, and magnesium can help lower blood pressure. These include fruits, vegetables, whole grains, and lean meats. The DASH diet is often recommended as it is rich in these nutrients.
Lifestyle ManagementAre there any activities I should avoid if I have high blood pressure?
It is important to avoid smoking, limit alcohol, manage stress, avoid certain medications that can raise blood pressure, and consult a healthcare provider before starting any new exercise program.
Lifestyle ManagementHow often should I check my blood pressure?
Ask your healthcare provider how often you should have your blood pressure checked. It may need to be checked more often if your blood pressure is not well-controlled.
Monitoring and Follow-upWhat are the emergency symptoms of high blood pressure?
If you have severe headache, nosebleed, chest pain, shortness of breath, irregular heartbeat, vision problems, or severe anxiety, seek emergency medical attention as these could be signs of a hypertensive crisis.
Emergency SymptomsCan high blood pressure be cured?
While there's no cure for high blood pressure, it can be controlled with lifestyle changes and medication. It's a chronic condition that requires ongoing management.
PrognosisWhat is the difference between systolic and diastolic blood pressure?
Systolic blood pressure is the top number in a blood pressure reading and indicates the pressure in arteries when the heart beats. Diastolic blood pressure is the bottom number and indicates pressure when the heart rests between beats.
Understanding Blood Pressure ReadingsIs it safe to take over-the-counter pain relievers if I have high blood pressure?
Some over-the-counter pain relievers, like NSAIDs, can increase blood pressure or interfere with medications for high blood pressure. Always consult with your doctor before taking any medication.
