My brother was born premature (8 months). Since then he always suffer from one or the other problems. Now he is 14 years of age as on today. He finds himself very struggling with every little aspect of life. His body catch cough and cold very frequently. By mind he is strong but his body metabolism is very weak. I am too much concerned about his coming life time when he will attain the age of 20 He may not be able to compete with his fellow being and feel himself inferior. Doctor please suggest some proper and stable treatment. Thank you very much.
