Final answer:
The greatest potential reduction in blood pressure for a hypertensive patient with a BMI of 30 could be through weight loss, which directly eases the cardiovascular system's workload. However, a combination of regular exercise, medication, and dietary changes typically constitutes a comprehensive treatment plan.
Step-by-step explanation:
Treating hypertension involves multiple strategies, including lifestyle changes and medication. In a patient with a BMI of 30, significant interventions for potentially reducing blood pressure are needed. Among these strategies, the one yielding potentially the greatest reduction in blood pressure could be weight loss, as it can directly reduce the strain on the cardiovascular system, improve efficiency of the heart, and often results in better overall health outcomes. However, this depends on individual circumstances and a comprehensive treatment plan often includes a combination of regular exercise, medication, and dietary changes. Medications are effective and may quickly lower blood pressure but should be part of a long-term management strategy that includes lifestyle modifications for sustainable health benefits.
