Dairy Intolerance
Clear signs, key differences from allergy, and when testing is worth it if milk, cheese or yoghurt leave you feeling off-kilter.
What is dairy intolerance?
Dairy intolerance is a non-allergic reaction to dairy foods. It may involve difficulty digesting lactose or sensitivity to milk proteins. Symptoms are typically delayed and linked to how much you eat.
If you ever have fast reactions like swelling or breathing issues, contact a doctor immediately.

FAQs
Is dairy intolerance the same as lactose intolerance?
No. Lactose intolerance is difficulty breaking down lactose. Dairy intolerance can also involve sensitivity to proteins. Both are delayed and non-allergic.
How long do symptoms take to appear?
Often within 24–72 hours, which is why testing and a structured re-introduction can help identify triggers.
Do I need to cut dairy completely?
Not always. Many people adjust portion size or frequency, or choose lactose-free options. Testing helps personalise your plan.
