Blood pressure is the force that circulating blood exerts against the walls of your arteries, and it is recorded as two numbers measured in millimeters of mercury. The top number, systolic pressure, reflects the force during heartbeats, while the bottom number, diastolic pressure, reflects the force between beats. Hypertension is the medical term for consistently elevated blood pressure, typically defined in the United States as readings at or above 130/80 mmHg. This condition often develops gradually and may show no obvious symptoms for an extended period. Here is more information about how hypertension is diagnosed and how to manage your blood pressure:
Diagnostic Tests
A healthcare provider usually confirms hypertension after taking readings on separate occasions, since a single high measurement does not typically establish a diagnosis. Providers use a blood pressure cuff, and they may repeat the reading on both arms for accuracy. Some patients receive a portable device for ambulatory monitoring. It records pressure throughout a full day.
Beyond the cuff itself, a provider may order more laboratory work to understand more about the patient’s health status. The doctor may order an electrocardiogram to assess how the heart is functioning. Blood tests can check:
- Cholesterol levels
- Blood sugar levels
- Electrolyte levels
Lifestyle Modifications
Diet plays a role in blood pressure management, and reducing sodium intake is one recommendation that may lower blood pressure. While providers suggest eating more vegetables and fruits, they may also encourage whole grains and lean proteins, too. Portion control and maintaining a healthy weight can also support these goals over time.
Physical activity supports overall cardiovascular function. A provider may recommend a specific weekly target, and they will often tailor that goal to your current fitness level. Walking, cycling, and swimming are examples of activities that many people can sustain.
Prescription Medications
When lifestyle changes alone do not bring numbers within a target range, a provider may prescribe medication. Several drug classes exist, including:
- Diuretics
- ACE inhibitors
- Calcium channel blockers
- Beta-blockers
Some patients take a single medication, while others may need a combination to reach their target. Providers often start with a low dose and adjust it over follow-up visits. Any changes to a prescription should be discussed with the provider because stopping medication abruptly can affect readings.
Ongoing Monitoring
Regular monitoring helps track how well a management plan is working, and it allows providers to adjust treatment when needed. Some patients use a home monitor that records readings between appointments. Keeping a log or journal gives your provider more data to review at follow-up appointments. These give the provider a chance to reassess your progress. Readings can change with time, weight, and other factors, so periodic check-ins support consistent care. During these visits, a provider may repeat certain tests to confirm that the plan remains appropriate.
Manage and Treat Hypertension
Managing hypertension involves multiple factors, and these can include medication and lifestyle adjustments. Your provider may also order other tests to evaluate kidney and vascular health, since these organs and systems are closely connected to blood pressure.
