Blood Pressure Overtreatment: Are We Treating the Number Instead of the Person?

High blood pressure is a major risk factor for heart disease and stroke. Appropriate treatment saves lives.

But there is another side to the story: inaccurate measurements, treatment based on isolated readings, medication that is no longer appropriate, and insufficient attention to the harm caused when blood pressure falls too low.

For some older adults, the problem may not be simply uncontrolled hypertension. It may also be overtreatment.

The question is straightforward: Are we paying enough attention to the individual—or too much attention to the number?

One Reading Shouldn’t Tell the Whole Story

Blood pressure fluctuates naturally throughout the day. Stress, pain, recent exercise, caffeine, dehydration, posture and the circumstances of a medical appointment can all affect a reading. Incorrect cuff size or measurement technique can also produce misleading results.

Some people experience white-coat hypertension: their readings are elevated in a medical setting but lower outside it.

The 2025 American Heart Association/American College of Cardiology guideline emphasizes accurate measurement, repeated readings and appropriate home or ambulatory monitoring.

An isolated high reading may warrant investigation. It should not automatically determine someone’s long-term treatment.

Why Older Adults Deserve Particular Attention

Blood pressure fluctuations occur at every age, but the consequences of treatment errors can be particularly serious for some older adults.

Orthostatic hypotension occurs when blood pressure drops upon standing. It can cause dizziness, weakness, blurred vision and fainting. Dehydration, medical conditions and medications—including blood pressure drugs—can contribute.

When someone is taking several medications, adding another drug or increasing a dose without considering the whole picture may worsen these problems.

The potential consequences include falls, fractures, injuries and loss of independence.

Dizziness and repeated falls should not automatically be dismissed as part of aging. They deserve investigation, including a review of blood pressure and medications.

When Blood Pressure Becomes Too Low

Public health messages rightly emphasize the dangers of high blood pressure. But excessive lowering can also cause harm in susceptible individuals.

Warning signs can include:

• Dizziness or light-headedness, particularly when standing.
• Fainting or near-fainting.
• Unexplained weakness or fatigue.
• Blurred vision or difficulty concentrating.
• Falls or a noticeable decline in everyday functioning.

There is no single blood pressure number that is too low for everyone. Symptoms, usual readings, standing blood pressure, medical conditions and medications all matter.

Low blood pressure can sometimes cause temporary confusion or impaired functioning. However, it would be misleading to claim that blood pressure medication generally causes long-term cognitive decline. High blood pressure itself increases the risk of stroke and cognitive impairment, and appropriate treatment can help protect the brain.

The issue is not whether medication is good or bad. It is whether the treatment remains appropriate for the individual.

The Hospital Problem: Treating a Number

Blood pressure can rise temporarily during hospitalization because of pain, anxiety, acute illness, disrupted sleep or other factors.

An elevated reading does not automatically mean that a patient has a hypertensive emergency.

The American Heart Association’s 2024 scientific statement highlighted uncertainty about the benefits and risks of treating asymptomatic elevated blood pressure in emergency and hospital settings. It emphasized proper repeat measurements and addressing underlying causes rather than reflexively adding medication.

The 2025 U.S. hypertension guideline also warns against using additional intermittent intravenous or oral medication to acutely lower severe blood pressure in hospitalized patients with noncardiac conditions when there is no evidence of acute target-organ damage.

Observational research has associated intensive inpatient treatment with adverse outcomes, including acute kidney injury and longer hospital stays.

This does not mean dangerous hypertension should be ignored. A hypertensive emergency involving acute organ damage requires urgent treatment.

The distinction matters: a high number is not automatically a medical emergency.

When Protocols Replace Judgment

Healthcare protocols exist for good reasons. They help clinicians recognize danger, reduce omissions and deliver consistent care.

But a protocol can become counterproductive if it replaces individualized judgment.

Consider a patient whose blood pressure rises during a hospital stay. Medication is added, and the prescription remains on the discharge list. Later clinicians continue it, even if nobody has established the patient’s usual blood pressure outside the hospital or investigated dizziness and falls.

This is a potential failure of care, not proof that every hospital operates this way.

Responsibility can become fragmented. One clinician starts a medication, another renews it, and nobody reassesses whether it is still necessary.

The deeper concern is a system in which a numerical target can trigger action while the patient’s symptoms, circumstances and changing needs receive less attention.

Protocols should support clinical judgment, not replace it.

Why Is It Easier to Add Medication Than to Remove It?

Starting a drug to reduce a visible risk can feel like decisive action. Reducing it may feel more uncertain, particularly when the medication was prescribed to prevent a future heart attack or stroke.

There are legitimate reasons to be cautious about stopping effective treatment. But caution should work in both directions.

Medication reviews should consider current readings, symptoms, standing blood pressure, other prescriptions, kidney function, cardiovascular risk and the original reason for treatment.

For some patients, continuing medication is clearly appropriate. For others, a clinician may decide that the dose or combination needs adjustment.

The goal is not indiscriminate deprescribing. It is to prevent prescriptions from continuing on autopilot without reassessment.

What Patients Can Do

A validated upper-arm home blood pressure monitor can help establish whether elevated readings are typical or occasional.

For reliable measurements:

1. Avoid caffeine, smoking and exercise for at least 30 minutes beforehand.
2. Empty your bladder and sit quietly for five minutes.
3. Keep your back supported, feet flat and legs uncrossed.
4. Put the cuff on bare skin and support your arm at heart level.
5. Do not talk during the measurement.
6. Take two readings about one minute apart and record both.

Use the correct cuff size. Take your monitor to a healthcare appointment so staff can review your technique and compare it with the office equipment. Because blood pressure varies naturally, differences between individual readings do not automatically mean a device is inaccurate.

If you take several blood pressure medications or experience dizziness, fainting or unexplained falls, ask whether your blood pressure should be checked while standing and whether your medication regimen needs review.

Useful questions include:

• Is my treatment based on repeated, properly measured readings?
• What target is appropriate for my health and circumstances?
• Could my medications contribute to dizziness or falls?
• Should we check my blood pressure while standing?
• Is every medication still necessary at its current dose?
• When should we reassess the benefits and risks?

Never stop or reduce prescribed medication without discussing it with your healthcare professional. Some medications require careful adjustment, and stopping treatment can carry real risks.
