What is Lactose Intolerance?
Lactose intolerance is a common digestive issue where the body has difficulty fully digesting lactose, a sugar found in milk and dairy products. This happens because of a deficiency in lactase, the enzyme that breaks down lactose in your body.
Lactase converts lactose into simple sugars in the small intestine. Most people naturally produce less lactase as they get older, which can make it harder to enjoy dairy products like ice cream, cheese, or yogurt.
If you have lactose intolerance, you might feel these things after eating or drinking dairy:
- Bloating and gas
- Stomach cramps
- Diarrhea
- Nausea
The severity of these symptoms depends on the amount of lactose consumed, the level of lactase your body produces, and even the types of bacteria in your gut.
The Genetics of Dairy Digestion
Why do some people struggle to digest dairy as they age? For most, it’s because their bodies produce less lactase over time, and this change is largely influenced by genetics.
The MCM6 gene acts like a switch that controls when and how much lactase is produced by our bodies. Some people have variations in this gene that allow them to keep producing lactase into adulthood, a condition known as lactase persistence.
Lactase persistence is more common in populations with a long history of dairy consumption, such as those in Europe and certain parts of Africa. These groups are more likely to carry variations in the MCM6 gene that allow them to continue enjoying dairy products without discomfort.

Digestive problems can be caused by different dietary components. A sensitivity to gluten (celiac disease) is another common digestive problem. You may also be interested in our Celiac Disease Risk Test.
