Lactose intolerance

Lactose intolerance occurs when you experience symptoms like stomach pain after consuming foods that contain lactose, a sugar present in dairy products. You can manage these symptoms by either eating smaller amounts of lactose-containing foods or by eliminating them from your diet altogether. Symptoms can appear within minutes or hours after ingesting lactose. Typical signs of lactose intolerance include abdominal discomfort. Additionally, you might experience other non-digestive symptoms, such as headaches, fatigue, and pain in your joints or muscles.
