What should you know about Greek yogurt and lactose intolerance?

Lactose intolerance happens when the small intestine does not make enough lactase to digest lactose, the natural sugar in milk. Undigested lactose reaches the colon, where it can draw in water and be fermented by bacteria. This may lead to bloating, abdominal pain, gas or diarrhoea after dairy. Straining and fermentation mean Greek yogurt may contain less lactose than some other dairy products, although it is still dairy and can still trigger symptoms.

Lactose intolerance is different from a milk allergy. Allergy symptoms can include hives, swelling, wheezing or vomiting and need medical assessment, especially if breathing is affected.

Check the label, choose a plain product and begin with a small serving alongside other food. Keep a brief record of the product, portion and symptoms over the following hours. If tolerated, increase gradually only as comfortable. Lactose-free yogurt is another option. Do not remove all dairy long term without planning calcium and vitamin D sources; Nutrition Counselling can help tailor replacements. If symptoms are frequent or unclear, Food Intolerance Testing may be discussed with a clinician.

Arrange a clinical review for ongoing diarrhoea, weight loss, blood in stool, persistent abdominal pain, nighttime symptoms or symptoms after many different foods. Seek emergency help for lip or tongue swelling, wheezing, trouble breathing, faintness or a rapidly spreading allergic rash after yogurt.

Ask whether your pattern fits Lactose Intolerance, how to test tolerance without losing key nutrients, and whether another digestive condition or milk allergy should be considered.
