Lactose intolerance is a common digestive issue that affects many people, especially in adulthood. In this article, we’ll explore what lactose intolerance is, the causes of it, and how to manage it.

Can You Develop Lactose Intolerance Later in Life?

Lactose intolerance occurs when your body can’t break down lactose, which is a sugar found in milk and other dairy products. This leads to discomfort and digestive issues. It’s possible to develop lactose intolerance at any age, but it’s most common in adulthood. Some people may have symptoms from a very young age, while others may develop them later in life due to certain factors.

Common symptoms of lactose intolerance include nausea, diarrhea, gas, and bloating. These symptoms typically occur within 30 minutes to two hours after consuming dairy products. However, the severity of symptoms can vary from person to person.

The Genetics of Lactose Intolerance: What You Need to Know

The science behind lactose intolerance is related to genetics. People who are lactose intolerant have low levels of lactase, which is the enzyme that breaks down lactose. This can be due to inherited traits that can lead to the condition. Individuals with certain ethnic backgrounds, such as African, Asian, and Hispanic, are more likely to be lactose intolerant than those of European backgrounds.

In addition, it is common for people who are lactose intolerant to have family members who also suffer from the same condition. Inherited traits play a significant role in lactose intolerance, making it a genetic issue.

Is There a Cure for Lactose Intolerance?

While there is no cure for lactose intolerance, there are several ways to manage the condition. Many people are able to manage their symptoms through simple dietary changes.

One common way to manage lactose intolerance is by limiting or avoiding dairy products. This may include switching to lactose-free milk and dairy products, as well as using substitutes like soy, almond, or coconut milk. In addition, supplements like lactase enzyme tablets can also help break down lactose.

Lactose Intolerance vs. Milk Allergy: Understanding the Differences

It’s important to distinguish between lactose intolerance and milk allergy, as they are two different conditions that have different causes and symptoms. People with milk allergy experience an immune response to the proteins found in milk and dairy products, while lactose intolerance is a digestive issue related to the inability to break down lactose.

Milk allergy symptoms can include hives, difficulty breathing, and in severe cases, anaphylaxis. Lactose intolerance symptoms, on the other hand, are typically related to gastrointestinal discomfort and digestive issues, such as diarrhea or bloating.

Preventing Lactose Intolerance: Can It Be Done?

While there is no foolproof way to prevent lactose intolerance, there are steps that can be taken to reduce the likelihood of developing the condition. One way is to limit dairy intake during childhood or early adulthood, as this is when lactose intolerance is most likely to develop.

Additionally, maintaining a healthy, balanced diet and incorporating probiotics can help promote digestive health and reduce the risk of developing lactose intolerance.

Living with Lactose Intolerance: Tips for Managing Your Diet and Symptoms

Managing lactose intolerance can be relatively simple, but it does require some adjustments to your diet and eating habits. Tips for managing the condition include reading labels and identifying lactose in foods, making substitutions in your diet, and keeping a food diary to track symptoms and identify trigger foods.

It’s also important to talk to your doctor or a registered dietitian to develop a plan that works best for you, and to ensure that you are still getting the nutrients you need in your diet.


Lactose intolerance is a common issue, but it can be managed with the right dietary and lifestyle adjustments. Understanding the symptoms of lactose intolerance, the genetics behind it, and ways to manage the condition can help individuals with lactose intolerance live a healthy and fulfilling life. As always, it’s important to seek a proper diagnosis and treatment.
