Lactose intolerance is the inability for some people to digest lactose, which is a sugar found in milk and dairy products, causing side effects for some people. The body naturally produces the lactase enzyme in the small intestine, unless a person is lactose intolerant. The main role of lactase is to change lactose into glucose and galactose. Then the body cells use this simple sugar in a form of energy to transport nutrients. A person who has lactose intolerance may feel diarrhea, feeling bloated , abdominal pain, nausea ,gas and feeling sick after they eat or drink something that contains lactose between 30 minutes to 2 hours.
Lactase intolerance may cause lactase deficiency and lactase malabsorption.

Lactose malabsorption refers to inefficient digestion of lactose that passes to the colon. Then bacteria can break the undigested lactose in the colon, and then lactose intolerance will occurred. Most people can drink and eat a small amount of lactase, and they don’t feel any symptom. Lactase intolerance is not food allergy; it is a digestive system disorder.
