Lactose intolerance is not a true allergy, but rather a digestive condition. Here's how it works: Lactose is the natural sugar found in milk and dairy products. Lactase is the enzyme in your small intestine that breaks lactose down into glucose and galactose for absorption.

Belching—also known as burping—is a normal physiological process. It can arise naturally or be triggered by dietary habits and digestive disorders. Both Western medicine and Traditional Chinese Medicine (TCM) provide valuable yet distinct perspectives on this common occurrence.
