Is 108-110 lbs normal for someone who's between 5'7-5'8?

You are considered underweight by society and doctors. However, if you eat normal 3 meals a day and you are getting the nutrients you need don't even worry about it. Some people thin body structures. So don't fret. You are probably very healthy and still growing. :)

Since you are 14 it is somewhat normal for you to be lighter. For your height it may be considered underweight. I am 5'3" and weigh 110 lbs and the doctor told me I'm average so you would have to gain a little to probably be average for your height.

It's actually a touch underweight. But you don't need to put on more than, say, 15 pounds. Just don't lose any more! Contrary to popular opinion, being seriously underweight is NOT healthy!

Normal I'm 5"2 and I weigh alot more than that ... how i long to be 110lbs

Hun your 14. It doesnt matter. Your probably perfect

It depends. if your very active and healthy it should matter, but if you don't ingage in much activity you need that extra weightm, exspeacialy if you get sick
