Customer question:
What is lactose? Anonymous customer's question
Pharmacist's answer:
Lactose is a type of sugar naturally found in dairy products. It is a disaccharide consisting of two sugar molecules: glucose and galactose. Lactose is specific to milk and milk products and is the primary energy source for babies.
Lactase is the enzyme needed to break down lactose in the digestive system. However, the body's ability to produce lactase can decrease with age, leading to lactose intolerance in some people. Lactose intolerance is when an individual experiences discomfort, bloating, diarrhea, or other digestive problems after consuming dairy products.
Dairy products containing lactose include milk, cheese, yogurt, and other foods. There are also lactose-free products where the lactose is previously "divided" into simpler sugars (glucose and galactose) or removed, which allows people with lactose intolerance to consume such products without significant problems.
