I am not sure if I have Celiac or Crohn's. I am a 15 year old male, and I weigh 82 lbs and about 5 feet tall. I have noticed symptoms of delayed growth and chronic diarrhea. I was tested for Celiac with a blood panel, but the results returned negative. I am now scheduled to have some type of biopsy to see if I have Crohn's. At this point, I'm hoping I have Celiac. I read about Crohn's, and it made me very nervous and scared. Please help me!!!
