  • Secondary lactose intolerance: is due to an injury or infection. Any terrible effect to the small gut can cause less manufacturing of lactase. Diseases, together with Crohn’s and celiac, are usually associated with this type of lactose intolerance. Surgery, treatment, or chemotherapy can also restrict manufacturing of the enzyme.

Is Lactose Intolerance Genetic?

The sort of lactose intolerance someone suffers from determines whether genes play a role or not. For primary lactose intolerance, the most common form, genetics do play a function. Located within chromosome 2, the MCM6 gene allows control the activity or expression of the LCT gene.

The ability to tolerate lactose depends at the type of MCM6 model a person has. The LCT gene follows the instructions provided through MCM6 and either produces adequate lactase to digest milk or not sufficient. For infants born with congenital lactose intolerance, the MCM6 gene is accountable to very little lactase production at birth.

Can You Become Lactose Intolerant?

The test takes about three hours and begins with eating a lactose-heavy beverage. Afterwards, the patient’s breath is analyzed at normal intervals to determine the amount of hydrogen. Hydrogen is detectable at higher level if a person is lactose illiberal.
