Is being lactose intolerant normal

Is being lactose intolerant normal?

Lactose intolerance is more common than you might think. In fact, millions of people around the world experience discomfort after consuming dairy products. If you’ve ever felt bloated or had an upset stomach after eating ice cream or drinking milk, you may have wondered if something was wrong. So if you were wondering, is lactose intolerance is normal, lactose intolerance is not only normal—it’s incredibly common! Understanding what lactose intolerance is, and how to manage it can help you lead a more comfortable and healthier life.

What is lactose?

Lactose is a type of sugar found in milk and other dairy products. It’s a valuable source of energy, but to digest it, our bodies need an enzyme called lactase. This enzyme breaks down lactose into simpler sugars, glucose, and galactose, which are absorbed by the intestines and used by the body for energy.

How the body processes lactose

In people with normal levels of lactase, this process happens smoothly. However, if your body doesn’t produce enough lactase, lactose isn’t broken down properly. Instead, it moves into the colon undigested, where it is fermented by bacteria, leading to symptoms like bloating, gas, and diarrhea​. Supplementing the body can help with the digestion of lactose.* An example of a supplement with lactase is Lactase 20,000.

Why some people lack lactase
Lactase deficiency can be genetic or age-related. Most babies are born with the ability to digest lactose, but as we age, many people naturally produce less lactase. This decline is especially common in certain ethnic groups, such as people of East Asian, African, and Native American descent, where lactose intolerance is more prevalent​.

Is lactose intolerance common?

Yes, being lactose intolerant is very common. In fact, about 65% of the global population has some level of lactose intolerance after infancy. In parts of East Asia, up to 90% of adults are lactose intolerant. Even in Europe, where dairy consumption is high, lactose intolerance affects a significant portion of the population​

Cultural and genetic factors
Lactose intolerance is most common in populations where dairy farming was historically less prevalent. Genetic factors play a large role in whether someone will retain the ability to digest lactose into adulthood. This means that while some people can enjoy dairy without issues, for others, lactose intolerance is a perfectly normal part of life.

Comparison to dairy tolerance
The notion that everyone should be able to digest dairy is a misconception. In reality, the ability to consume lactose without any issues is more of a genetic adaptation than the norm. For many, being lactose intolerant is just a natural part of their biology.

Diagnosis and testing

If you suspect you might be lactose intolerant, there are a few ways to find out. A hydrogen breath test is one common method, where your breath is analyzed for increased hydrogen levels after consuming lactose. Another option is the lactose tolerance test, which measures how your body processes lactose through blood glucose levels​

Consulting a professional
It’s always a good idea to consult with a healthcare provider or dietitian if you suspect lactose intolerance. A dietitian or doctor can offer personalized advice, recommend tests, and help you plan a diet that meets your nutritional needs without causing discomfort​.

Living with lactose intolerance

Dietary adjustments
Living with lactose intolerance doesn’t mean you have to give up dairy completely. Many people manage their symptoms by switching to lactose-free alternatives, such as lactose-free milk, cheese, and yogurt. Plant-based alternatives like almond or oat milk are also great options​.

Lactase supplements
For those who don’t want to give up dairy entirely, lactase enzyme supplements can reduce occasional complaints. These supplements help your body digest lactose more efficiently*, allowing you to enjoy dairy again!

Balancing nutrition
Dairy products are rich in essential nutrients like calcium and vitamin D, which are important for bone health. If you choose to reduce or eliminate dairy, it’s important to find alternative sources for these nutrients. Fortified plant-based milk, leafy greens, and supplements can help ensure you’re meeting your nutritional needs​. You can consult a specialized dietitian to get personalized advice. If you suspect a lactose intolerance, take the intolerance test to get useful insights and tips.
