Does Yogurt cause diarrhea?
Yogurt may cause diarrhea for some people with IBS because it is high FODMAP and can deliver lactose. The reaction is usually dose-dependent, but sensitive people may notice symptoms even from small amounts.

Why Yogurt may trigger symptoms
Regular yogurt is high in lactose. Lactose-free or coconut yogurt is the gentler swap.
Diarrhea can happen when some carbohydrates or sugar alcohols pull water into the gut or when a meal moves through too quickly. FODMAP load is one possible factor.
For IBS-sensitive people, the total meal matters. A food can feel different when it is paired with wheat, dairy, beans, sugar alcohols, large portions, alcohol, or a stressful day.
