REVERSIBLE HYPERTENSION AND HYPOTHYROIDISM

Abstract

Six patients with hypothyroidism and hypertension whose blood pressure fell to normal when treated with thyroxine (172.7.2/112.2.1 to 140.3.2/84.1.6 mmHg, P−1.h⁻¹) was low before treatment. Hypertension with low plasma renin is consistent with sodium retention. Hypertension in the hypothyroid patient only requires further evaluation if it persists after adequate treatment with thyroxine.
