At least in the case of long-lasting anorexia or bulimia, physical impairments may persist even after the illness. That does not have to happen, but it can happen. The cause is then the years of massive malnutrition.
Especially the kidneys can be affected. Fasting, vomiting, laxatives and diuretic drugs (diuretics) shift the balance of electrolytes in the body. In the long term, this can affect the excretory function of the kidneys. Low fluid intake also contributes to kidney damage. However, there are of course many people with previous anorexia or bulimia, who have no problems with the kidneys.
Anorexia: sometimes infertility can persist
Years of vitamin D deficiency due to malnutrition can also affect bone metabolism. As a result, the bones become too soft or porous (osteoporosis), making it easier to break bones.
The household of sex hormones may remain disturbed even after reaching normal weight. Not all formerly anorexic are fertile and can have children.
Bulimia vomiting can also damage tooth structure. Because the acids of the stomach contents attack the enamel and destroy it.
All in all, one has to say: All this is harmless against the danger that anorexia nervosa can not be treated successfully even in the longer term.
