Lactose Intolerance: An In-Depth Guide
Description
Lactose intolerance is a common digestive condition that affects people who lack the enzyme lactase. Lactase is necessary to break down lactose, a sugar found in milk and dairy products. Without lactase, lactose passes undigested into the large intestine, where it is fermented by bacteria, producing gas, bloating, and diarrhea.
Associated Diseases
Lactose intolerance is often mistaken for other digestive conditions, including irritable bowel syndrome (IBS) and celiac disease. While IBS shares similar symptoms, it is caused by a different underlying mechanism. Celiac disease is an autoimmune disorder that causes damage to the small intestine when gluten is consumed.
Did you Know ?
Approximately 65% of the global population is lactose intolerant. The highest prevalence is found in Southeast Asia and Africa, while the lowest is in Northern Europe.
