Is it Possible for Lactase Enzymes to Redevelop in a Lactose Intolerant Person’s Body?

Lactose intolerance can develop at any age and it can also appear to resolve and then redevelop in some individuals. This phenomenon is more common in certain situations and with specific triggers, which we will explore in this article. We often hear questions such as: can the body redevelop the necessary enzymes to digest lactose, or is lactose intolerance a permanent condition?

Understanding Lactose Intolerance

Lactose intolerance is a common disorder resulting from the deficiency of the enzyme lactase in the small intestine. Lactase is responsible for breaking down lactose, a sugar found in milk and dairy products. Typically, a person becomes lactose intolerant due to a genetic mutation or damage to the small intestine, which makes it unlikely for the lactase enzyme to redevelop. However, in some cases, temporary lactose intolerance may reappear after an illness or injury to the gastrointestinal tract.

Temporary Lactose Intolerance

Temporary lactose intolerance often occurs when a person's small intestine is under stress due to illness or injury. This stress can sometimes lead to a temporary reduction in lactase production. Once the underlying issue is resolved, lactase levels may rebound, leading to improved lactose tolerance. However, this is a temporary condition, and the ability to digest lactose may not fully return to pre-illness levels.

Chronic Lactose Intolerance

For individuals experiencing chronic lactose intolerance, the lactase enzyme is either absent or significantly reduced, making it unlikely for the body to redevelop this enzyme. Lactose intolerance is generally a lifelong condition, and dietary adjustments are typically necessary to manage lactose consumption.

Enzyme Replacement Therapy

While the body cannot redevelop the lactase enzyme on its own, enzyme replacement therapy (ERT) can provide a viable solution for lactose intolerance. ERT involves taking lactase enzyme supplements, such as Lactase tablets, which help in digesting lactose. These supplements are easily accessible and can be found in most grocery stores and pharmacies.

Practical Steps for Managing Lactose Intolerance

Here are some practical steps individuals can take to manage lactose intolerance:

Start with small amounts of lactose-containing foods: Gradually increasing lactose consumption can help some individuals build tolerance over time. Starting with small amounts and gradually building up may allow the body to adapt. Select lactose-free or lactose-reduced dairy products: Many dairy products are now available in lactose-free forms, making it easier to enjoy milk and dairy without digestive issues. Take lactase enzyme supplements: Lactase enzyme tablets can be taken with meals containing dairy products, helping to break down lactose and reduce symptoms. Consult a healthcare professional: A doctor or registered dietitian can provide personalized advice and recommendations based on individual needs and health status.

Scientific Insight and Expert Opinion

According to Sam Arora, an expert in Food Science from the University of Guelph, lactose intolerance is an irreversible change. Once an individual loses the ability to digest lactose, it is unlikely to redevelop. However, with some care and knowledge, managing lactose intolerance can be straightforward. Dr. Arora emphasizes the importance of living with and managing lactose intolerance for the rest of one’s life, but also highlights that with proper care, it can be effectively managed.

Dairy products will always be a part of many diets, but with the right information and tools, individuals can still enjoy them without the discomfort of lactose intolerance symptoms.
