Lactose intolerance, a common digestive disorder, affects millions of individuals worldwide. It occurs when the body lacks an enzyme called lactase, which is necessary for breaking down lactose, the sugar found in milk and dairy products. While some people are born with lactose intolerance, others can develop it later in life. In this blog post, we will explore whether it is possible to become lactose intolerant and discuss the factors that contribute to its development.

Genetic Predisposition:

Research suggests that genetics plays a role in determining an individual's susceptibility to lactose intolerance. Some individuals may inherit a genetic variation that reduces their ability to produce lactase, leading to lactose intolerance from birth or early childhood. However, the majority of genetic lactose intolerance cases are observed in specific ethnic populations, such as East Asians, Africans, and Native Americans.

Primary Lactose Intolerance:

Primary lactose intolerance refers to the most common form of lactose intolerance, where individuals develop symptoms later in life. This occurs due to a gradual decrease in lactase production. As individuals age, their bodies may produce less lactase, resulting in difficulty digesting lactose. Primary lactose intolerance can manifest at different stages of life, with the onset typically occurring during adolescence or adulthood.

Secondary Lactose Intolerance:

In some cases, individuals can develop lactose intolerance due to underlying health conditions or injuries that affect the small intestine. Conditions such as celiac disease, Crohn's disease, and bacterial overgrowth can damage the intestinal lining or reduce lactase production, leading to secondary lactose intolerance. Additionally, certain medications, such as antibiotics, can temporarily disrupt the balance of gut bacteria and cause lactose intolerance symptoms.
