Am i underweight?

im 5 10 and weigh 120 pounds am I underweight?

I calculated you Body Mass Index to be 17.2
This is in the underweight range, but only just.
here are the ranges:
* Underweight = 18.5
* Normal weight = 18.5-24.9
* Overweight = 25-29.9
* Obesity = BMI of 30 or greater
All this means, is that comparing you're height to you're weight puts you slightly underweight, I wouldn't worry to much, as you're only just in the underweight category.

remember, you're genetic makeup, race, where you live and all sorts of things contributes to what you're healthy weight range should be. best thing to do it go to you're local doctor and have a chat.

It's not slightly underweight, it's a lot underweight, anorexics have a bmi of under 17.5 (not that I'm saying you have anorexia...)

Hey! Im 5'9 1/2'' and weigh about 130. I dropped down to 119 a little less than a year ago from being so busy but to answer your question, yes you are slightly underweight. Everyone has a different body type but it up to you if you like how you look or not. Hope I helped!

yes because you bmi is 17.2
