Blood Pressure Reading of 155/84 – Do You Need Medication?

When someone has a blood pressure reading of 155/84 mmHg, it indicates that the systolic pressure is elevated while the diastolic remains within a relatively normal range. If this measurement is consistent upon repeated testing, it may signal the need for medical intervention. The ideal blood pressure is generally considered to be below 120/80 mmHg, and readings above 140/90 mmHg are typically classified as hypertension. Even if the diastolic pressure is under 90 mmHg, a systolic pressure above 140 mmHg can result in a diagnosis of isolated systolic hypertension.

Understanding the Diagnosis

A systolic pressure of 155 mmHg falls into the category of mild to moderate hypertension. A consistent reading above 140 mmHg over time confirms the condition. At this stage, it is crucial to monitor blood pressure closely and consider further diagnostic tests to evaluate potential organ damage.

Recommended Medical Assessments

If diagnosed with mild hypertension, your healthcare provider may recommend regular blood pressure monitoring and a series of tests to assess the impact on vital organs such as the heart, brain, and kidneys. These tests can include an echocardiogram, electrocardiogram (ECG), urine protein analysis, and even a CT scan of the head to detect any early signs of damage.

When Medication Becomes Necessary

If the tests reveal signs of organ damage, such as left ventricular hypertrophy (thickening of the heart muscle), medication should be initiated promptly, even if blood pressure readings have slightly improved. The primary goal of hypertension treatment is to prevent cardiovascular events like heart attacks and strokes. If there is existing damage, lowering blood pressure becomes even more urgent.

What If No Damage Is Detected?

In cases where no immediate organ damage is detected, medication may still be recommended. However, some patients may opt for a "watchful waiting" approach for 3 to 6 months, especially if the condition is newly diagnosed. During this time, lifestyle modifications such as dietary changes, increased physical activity, and stress management can be effective in managing blood pressure without immediate pharmacological intervention. This approach does not typically pose any acute risk to health.
