My cousin is 16 and she suffered from anorexia nervosa for almost 2 years. will she be able to grow taller and what foods and exercises will help her?

She needs to eat: She needs to eat, get medical and psychiatric help. This is a very complex and dangerous condition.

It depends: At 16 she may have passed her growth spurt. A consult with a growth specialist may be needed. A regular diet with normal activity should be her goal. She should consult her pediatrician and a dietician.

Proper treatment: First and foremost she needs proper treatment for anorexia (therapy and counseling). If that is addressed, then a well-balanced diet with a calcium and vitamin d supplement should be beneficial, but she needs to follow such a plan under the care and advise of her physician.
