THE BLOOD VOLUME IN HYPERTHYROIDISM

Abstract

The circulating blood volume in 21 cases of hyperthyroidism, determined by the CO method, was much higher than the average normal volume. Of 15 cases in which subsequent determinations were possible following subtotal thyroidectomy, all but one (a case of toxic adenoma) showed a definite reduction of the blood volume after the operation. Five cases were studied after the administration of Lugol''s solution. This treatment alone had an appreciable effect in decreasing the blood volume along with the fall in the basal metabolic rate.
