I am not gaining weight and height, what should I do now ? I am 15 years and 6 months old. Height 5 feet 6 inches. Weight 50 kg. My problem is that I eat and drink properly. I eat milk , eggs , vegetables. But even then the weight does not increase. I don't eat fast food , soft drinks at all. I don't do sports , exercise , hard work. On the other hand, two years ago my height was 5 feet 4 inches. Now Mae has grown two inches in these two years. Where 12-16 year old boys are supposed to grow 3 inches a year, my height has increased by 1 inch. Before, everyone used to call me tall , but now no one says anything like that. Why weight and height are not increasing properly. I'm very tense. Please tell, whats the story of them big puppys ..... I want detailed and accurate answer.
