Hi there just looking for some advice. My son (7) is noticeably shorter than his peers and has had diarrhoea on and off for ages but seemed to settle on a lactose free diet. Anyway, friend suggested he be tested for celiac due to his short height as has been known to be a symptom of poor growth and I've found out today his immunoglobulin was way high at 100.20. I'll speak to the doctor tomorrow but since googling, I'm worried it's not celiac and something else as it says immunoglobulin is for all autoimmune diseases,.but the doctor did say he was tested for celiac so does that mean it's definitely celiac as an autoimmune disease? Getting paranoid it might be something entirely different!
