Lactose Intolerance & Bad Breath: What's the Connection?

Lactose intolerance causes gastrointestinal symptoms (bloating, gas, diarrhea) but is not directly linked to bad breath (halitosis). Halitosis is typically associated with poor oral hygiene, oral bacteria, certain foods, or underlying health conditions. Lactose intolerance stems from lactase enzyme deficiency, causing digestive issues after dairy consumption.
