Eating attitudes and glucose tolerance in anorexia nervosa patients at 8-year followup compared to control subjects.
This study analyzed eating attitudes and plasma glucose, insulin, unesterified fatty acid (FFA), human growth hormone (GH), and cortisol responses to an oral (100 g) glucose load in 26 female anorexia nervosa patients at an 8-year outcome evaluation in comparison to 14 age-matched female control subjects. Recovered patients who were of normal body weight and had cyclical menstruation (n = 19) showed glucose tolerance curves and insulin, cortisol, and GH responses that were indistinguishable from those of normal subjects, although patients tended to be more diet-conscious than controls and showed elevated fasting FFA levels. Two of 19 recovered patients met criteria for impaired glucose tolerance. Nonrecovered patients (n = 7) showed abnormal eating attitudes at an average underweight of 20% with persistent amenorrhea or oligomenorrhea. They had high fasting FFA plasma levels, significantly greater than normal rises in plasma glucose, a significant delay in serum insulin secretion, higher mean glucose levels before and after controlling for amount of exercise, and paradoxical release of GH. One of seven patients met criteria for diabetes mellitus and two of seven had impaired glucose tolerance. The findings suggest that fasting plasma FFA levels may reflect patients' eating and exercise habits more accurately than their verbal or written reports.
