My DD is 11yo and has ongoing digestive issues which have been getting worse. I know on her bio-dad side (no contact for over 7 years) there is a long history. Bio dad is lactose intolerant and bio-gran is lactose, gluten, soy.
DD says her tummy hurts after too much milk, bread makes her gassy. She bloats like a balloon sometimes and her bowels are either one extreme or the other.
Should I have her tested before eliminating from her diet? Which is more likely to be the issue gluten or lactose?
My other DD is 16 (different dad) and has issues with too much dairy but as long as she is careful and doesn't pig out on ice cream is ok.
