Understanding Lactase Deficiency: A Guide to Lactose Intolerance
Description
Lactase deficiency is a condition in which the body produces insufficient lactase, an enzyme that breaks down the sugar (lactose) found in dairy products. Without enough lactase, undigested lactose enters the large intestine, causing a range of digestive symptoms.
Associated Diseases
Lactase deficiency can be associated with certain underlying medical conditions, including:
- Congenital lactase deficiency: A rare condition where infants are born without lactase production.
- Primary lactase deficiency (adult-onset): The most common type, where lactase production gradually declines with age.
- Secondary lactase deficiency: Caused by damage to the small intestine due to conditions such as celiac disease, Crohn's disease, or infections.
Did you Know ?
Globally, around 65% of adults experience some degree of lactase deficiency. The prevalence varies widely by ethnicity, with higher rates among certain populations, such as those of African, Asian, and Native American descent.
