Disguised pernicious anaemia.

exacerbation of the adrenal insufficiency with return of anorexia, lassitude, loss of weight, and low blood pressure. Although patients with Addison's disease, treated with cortisone, are not usually hypersensitive to insulin, in this present case, as the patient's condition improved satisfactorily, and her insulin sensitivity was uncertain, the latter drug was not used immediately. It is interesting that her diabetes is controlled now without insulin, despite the fact that she needed insulin on her last admission and also during her subsequent relapse.
