Not eating enough- stomach pains- NEED QUESTIONS ANSWERED!

My friend, she is 15 years old, healthy, and a very healthy weight. Problem is she sometimes doesnt even get 2 meals in one day. She just doesnt feel like eating. she does get hungry sometimes and eats, but sometimes she doesnt.
She isnt concerned about her appearence she just plain doesnt want to eat sometimes.
For the past few days she has been complaining about stomach pains(abdominal pains or stomach pains)
she said they have not been this strong before, they seem to cause extreme discomfort. They go away in about 5 minutes but when they are there they are noticable. Happens a few times a day, even after she eats her stomach could still hurt like this.
please any insight would help

Your friend should see her doctor who is the only one qualified to diagnose what could be causing the stomach pains. It is not something to ignore since it seems to happen often and is getting worse.
