Dear Hello, Welcome to Healthcaremagic!
There are many causes of such low weight at your age-- like chronic inflammatory diseases- ulcerative colitis
, Crohn's disease, irritable bowel syndrome
, intestinal worms, coeliac
disease (wheat allergy
), etc. You also have stated nothing about your sexual development as your breast have not developed properly. What about menses? My advice is to consult an endocrinologist
also if sexual development is not there.
For weight gain-- reduce stress, take proper nutritious diet with high protein foods like milk, eggs, pulses, also meat if you take non-veg. foods. Also you can take butter as it has lots of energy. Wishing you best of health.
