my 8 year old daughter was just diagnosed with Crohn. in January her calprotectin level was 653, iron level low, CRP elevated, she had done endo and colonoscopy. Confirmed chronic inflamation. back in January she had for while loose stool and occasional belly pain. since then we changed diet (dairy free, gluten free 80%, very low sugar -no junk no processed. added probiotic, prebiotic, vit D, iron butyrate. no is March she repeated calprotectin and was 129. I was so excited, but went with her to doctor for intestinal ultrasound. The doctor said lot of inflammation and fistula on small bowel. she is symptom free. her stool solid (1-2 day), no pain at all. how do you explain this calprotectin fell down, she feels great, but ultrasound says completly different.
