Our now 13 month old was diagnosed with fpies roughly 2 months ago, been dealing with it misdiagnosed since 7 months. With many episodes behind us we have had our first month of success with foods being few but enough along with breast feeding to get her growing, finally! Our doctor at children's hospital in Boise is amazing, but even he can't figure out why her TSH is all over the board from 4.45-9.78 over 4 blood test. Also her ALT/AST is elevated in addition to her CK score was 205. wondering if anyone else's baby has had these test done & is there any similarity? Hoping as she stops have the vomiting episodes her blood scores will normalize but would love to know of anyone who might be able to give more insight. Thank for the help & the site.
