The Claim

In adults taking antihypertensive medications, weight loss reduces diastolic blood pressure by 5.31 mm Hg, which is significantly greater than the 2.91 mm Hg reduction observed in untreated individuals.

Cause and effect

In plain English

In adults taking blood pressure medication, losing weight lowers diastolic blood pressure by 5.31 mm Hg, which is a larger reduction than the 2.91 mm Hg seen in those not taking medication.

See the scientific wording

In adults taking antihypertensive medications, weight loss reduces diastolic blood pressure by 5.31 mm Hg, which is significantly greater than the 2.91 mm Hg reduction observed in untreated individuals, indicating that weight loss enhances the effectiveness of blood pressure medication.

Why this might work

Losing weight reduces fat tissue, which lowers a hormone system that tightens blood vessels and retains salt, while increasing another system that helps the kidneys remove salt and relax blood vessels. This combination lowers blood pressure more when blood pressure medications are already being taken because the drugs work better when these natural systems are restored.

    For people already taking blood pressure pills, losing weight lowers their diastolic pressure more than it does for people not on pills — the study shows this difference clearly, meaning weight loss helps the pills work better.
