Even though anorexic women show substantial weight gain and major reductions in psychological symptoms after three months of hospitalization, they continue to eat much smaller meals than women who have never had the disease.
Even though treatments in the hospitals are often successful, 30 percent to 70 percent of patients relapse when they go out into the real world. Patients eat normally during the treatment but fail once they are on their own.
During a trial, the patients were given yogurt shakes but they did not know what they are taking and how many calories the food had, so the anorexic people found the study situation very difficult. They just experienced a lot of anxiety around not being able to see the food and not being able to see what was in the food.
At least it is known about the problem now, so the right measurements can be taken for the post-hospitalization period.
