A. At his age, 117 pounds is actually just above average. That doesn't mean it is a healthy weight for him though. Instead of just looking at a child's weight, it is more important to know what their body mass index is.
Children with a BMI that is below the 5th percentile for their age are usually thought to be underweight. For his weight, he would already have to be over 6 feet tall to have a BMI below the 5th percentile though, so his weight may be okay.
Is he that tall? Since you describe him as being so skinny, he may very well be...
It is important to keep in mind that you can have a normal weight and normal BMI and still have an eating disorder. And you mention may of the common signs and symptoms that would raise some concern that your son has or is developing an eating disorder, including that he:
- has continued to lose weight, even though he is now 'too skinny'
- has an obsession with his weight
- exercises all of the time
- may not be eating enough food and getting enough calories
At this point, he likely needs a further evaluation from a health professional that has experience treating teens with eating disorders. A registered dietician might be a good place to start. If he really wants to be healthy and not just thin, they might be able to help him plan a healthy diet and make sure he is getting enough calories, vitamins, and other nutrients, to be healthy and continue to grow normally.
A counselor, psychologist, or psychiatrist might also be helpful, as can your Pediatrician, especially if they have developed a good relationship together.
If you are not sure where to take your child, the National Eating Disorder Association offers a referral service and can provide you with 'a list of doctors, nutritionists, counselors, and inpatient and/or outpatient facilities in your area.'
