Persistent or continuing hyperthyroidism is a condition in which after subtotal thyroidectomy the disease again becomes evident, either immediately or in a relatively short time. With recurrent hyperthyroidism, on the other hand, there is complete relief from the disease for a considerable period before it again becomes manifest. The dividing line between these two types of hyperthyroidism after operation is somewhat arbitrary. Thompson, Morris and Thompson1 said that the condition is recurrent if there is a return to normal for even one month after operation. Bisgard2 sets this dividing line at eight weeks; Jackson,3 at three months; Clute and Veal,4 at six months, and Young,5 at one year. I believe that a year is a likely period, since a patient who shows a return of symptoms with an elevated basal metabolic rate in nine months or so probably has a continuation rather than a recurrence
