Sir!! I Am 21 Year Old & Patient Of Sickle

Sir!! I am 21 year old & patient of Sickle cell disease. I think I know about it, its all symptoms, complications, causes, results etc. And for this I m taking folic acid tablet & Hydroxyurea regularly. SCD causes delayed growth of body & my problem is same "non-growing body". I want to have only a good or perfact body as other normal persons have.. So please sir suggest me any effective way to improve my health as well as body.
