Lactose

Drug Details

Lactose is a natural sugar found in milk and dairy products, composed of two simpler sugars: glucose and galactose. To digest lactose, the body produces an enzyme called lactase in the small intestine, which breaks down lactose into these simpler sugars for absorption. If the small intestine doesn't produce enough lactase, undigested lactose moves into the colon, where bacteria ferment it, leading to symptoms like bloating, gas, and diarrhea. This condition, known as lactose intolerance, is common among adults, especially those of Asian, African, and Hispanic descent. While lactose intolerance can cause discomfort, it is generally harmless and can often be managed by adjusting the diet to limit or avoid lactose-containing foods.
