The Effects of Weight Reduction on Blood Pressure in 301 Obese Patients

Arch Intern Med. 1990;150(8):1701-1704. doi:10.1001/archinte.1990.00040031701019

The effects of weight reduction on blood pressure were assessed in 301 obese patients. Weight reduction was achieved by behavior modification, medication, or their combination and was associated with significant reductions in systolic and diastolic blood pressure. The weight reduction method was less important than the amount of weight lost in determining reductions in blood pressure. The greatest reductions in weight and blood pressure occurred during the first half of weight loss, suggesting that even brief treatment (ie, 8 to 10 weeks) may benefit obese, hypertensive patients. Despite repeated measurements, 36 patients who failed to lose weight showed no decrease in blood pressure. Although blood pressure rose during follow-up in patients who regained weight, it remained below baseline levels. These findings provide further support for weight reduction in the control of hypertension.
