In brief: Allergy not just GI

Dairy intolerance is caused by an inability to digest milk sugar lactose into two simpler sugars.
This results in gas, cramps, bloating, flatulence & diarrhea. Dairy allergy may cause these same symptoms but typically also causes vomiting, skin rashes like hives or eczema & even triggers allergic rhinitis & asthma. If symptoms all GI try lactose-free milk. You'll have no symptoms if intolerant.
