Is milk good for lactose intolerance?

Lactose is the natural sugar in milk. When the small intestine makes too little lactase, lactose reaches the large intestine and is fermented, which can produce gas and draw in fluid. Symptoms may include cramps, [Bloating](/symptoms/bloating/), and [Diarrhoea](/symptoms/diarrhoea/) after dairy. This is different from a milk allergy. Some people handle small servings, especially with a meal, while others react to ordinary milk but tolerate yoghurt or hard cheese.

Keep a short food-and-symptom diary. Compare a small serving of ordinary milk with lactose-free milk only if a clinician has advised that a trial is appropriate. Check labels on plant-based drinks and choose products fortified with calcium and vitamin D when they replace milk. Do not remove several food groups without a plan, particularly for a child, pregnancy, or ongoing weight loss. [Nutrition Counselling](/treatments/lifestyle-and-wellness/nutrition-counselling/) can help protect dietary balance, and [Food Intolerance Testing](/treatments/diagnostics-and-screening/food-intolerance-testing/) may be discussed when the pattern is unclear.

Arrange an assessment for ongoing [Abdominal Pain](/symptoms/abdominal-pain/), repeated diarrhoea, blood in stool, vomiting, fever, or unintentional weight loss. Get urgent help for facial swelling, wheezing, breathing difficulty, or faintness after dairy, because those symptoms can signal an allergic reaction rather than lactose intolerance.

Ask whether your symptoms fit lactose intolerance, how to trial lactose-free products, whether calcium intake is adequate, and whether another digestive condition should be considered.
