Help for johnny

My son wasn’t feeling well,he stopped eating and going to the bathroom for two days,so I took him to the hospital where they diagnosed him with constipation,after taking his meds he still wasn’t holding anything down so after a few more days we brought him back,the hospital didn’t know what was wrong so they transported him to a children’s hospital due to his age and he’s been tested and still they have found nothing,he can’t hold anything down and the doctor is also worried that he’s lost more than 10% of his body weight already and he’s been sick for only two weeks,johnny is a great kid and stays on the honor roll in high school,he’s only a junior but he’s already been to leadership academy and is proud of his silvercord he has received.he wants to join the navy as a officer and I support him with his choices.unfortunately he is missing time with his unit and in school and I can see the look on his face and it’s killing me.the hospital bills will be way more than I can handle and I’ve been told to make a fund.so I figured I would try,thank you
