Hi, Welcome to Health care magic forum.
As you describe, it appears that you are short as well, any how if not, it is O.K.
As you wanted,
home remedies means, take more of calories, fats, fries, ice creams,and oily foods.
Try to sleep for more time practice early to bed and late to rise, try to sleep in the day time, at least for a while.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods,to have good health.
You may need to have
protein supplements, multivitamins, enzymes, and injections of anabolic
steroids which you can have with your doctors advise.
Wishing for a quick and complete recovery. Thank you.
