My rib and chest bones stick out. is this normal?

Question

i am 13 years old,5''4, 138 lbs. i use to be 154 lbs. and my bones never stuck out, but since i lost all of that weight my rib and chest bones just seemed to stick out and it looks like i am anorexic if i wear a low-cut shirt. i am not really that skinny. is this normal?

i am the only person in my family that is like this and my bust seem to sag a little.

Answer 1

well, im 13. im about 90 punds. and my chest bone sticks out.
it makes me feel unofortable to take my shirt off, and it looks
wierd for a guy.
i think its just a bone structure, my doctor said after puberty,
my bones should go back to how it was before.

Answer 2

Ok.. so im 25...5'7 and weigh 118lbs.. before i started working out 4 times a week, I weighed roughly 135.. but ive lost a bit of weight, and now my chest bones show as well and my b***s are pretty much gone..ughh!! But I took a water body fat text and i dont even have 10% body fat. But for your height and weight, I wouldnt worry to much about it. You seem fine to me:)
