title: Insulin secretion in obesity and diabetes: an illustrative case.
abstract: A patient with obesity and diabetes mellitus had insulin secretion studies done during a 3-year cycle of weight loss and regain in the course of which she progressed from frank diabetes to a normal state of carbohydrate tolerance and then back to her original diabetic state. The results suggest that therapeutic weight reduction not only reverses insulin resistance but also restores beta cell sensitivity and enhances beta cell capacity. The eventual re-establishment of a degree of obesity, hyperinsulinemia, and carbohydrate intolerance virtually identical to that originally seen is compatible with a primary disorder involving hypothalamic control of adipose stores and insulin secretion.
