Weight gain does not promise recovery from anorexia
The complete cure of anorexia goes a long way than simply weight gain of patients. Anorexia stricken patients who gain weight during treatment often spiral back into the eating disorder. New studies shed light on why relapse rates are so high.
The study shows that women who seemed to be getting better while participating in a hospital-based behavioral treatment program continued to show disturbed eating behaviors when their food intake was not carefully monitored.
The participant may have regained much of their lost weight with treatment along with improvements in depression and other psychological symptoms. However, they ate fewer calories when given an unrestricted test meal than women without anorexia.
“We saw a lot of psychological changes over the course of hospitalization,” researcher Robyn Sysko of the Rutgers University Eating Disorders Clinic, tells WebMD. “But when given more control over their eating, these patients still tended to eat less than they should.”
Examining eating behaviors
Most patients developed anorexia during their years as preteens, teens, or young adult. Nine out of 10 anorexics are female which research suggests that one in three women treated as inpatients for the eating disorder experiences a relapse within two years of discharge from the hospital.
Improvements in psychological symptoms and weight have been documented during hospitalization for anorexia nervosa. There is no clear evidence that similar improvement in eating disorder occurs. Sysko and colleagues write in the August issue of the American Journal of Clinical Nutrition.
The tests were done with participants of 12 hospitalized women with anorexia and 12 women without eating disorders the same number of calories at breakfast followed by an unrestricted-calorie test meal at lunch.
The test meal consisted of a large strawberry yogurt shake. Study participants were told to drink as much or as little as they liked. The anorexic patients were given the test both early in their hospital stay and later, after they had gained back a good deal of weight.
The non-anorexic study participants ended up drinking about half of their shakes, taking in approximately 500 calories. Early in treatment the anorexic patients took in about 145 calories at the test meal, and later in treatment they took in 240, which is still less than half of that eaten by the women without anorexia nervosa.
During both test meals, the hospitalized patients took in fewer calories than they would have if they had been eating their regular, supervised lunch.
“The fact that these patients didn’t show as much improvement in eating behavior as they did in other aspects of their treatment illustrates the importance of continuing care once hospitalization ends,” Sysko says.
Follow-Up is a must
The research concluded that weight gain is merely an initial step towards anorexia recovery. Follow up care and treatment is emphasized to avoid relapse that ultimately hampers recovery from the said eating disorder.
