10 Milky Mysteries Unveiled: The Sneaky Suspects Behind Lactose Intolerance

4. Ethnicity

Ethnicity is a strong risk factor for the development of lactose intolerance. The condition is more prevalent among Hispanics, American Indians, and patients of African or Asian descent. These patient populations may have a genetic form of lactose intolerance caused by a mutation in a gene that manufactures lactase. Known as hypolactasia, this disease begins during childhood, and it is especially common among individuals of Asian descent. Parents who have hypolactasia may wish to consider having their child tested for the condition. If it is present, patients may need to work with a gastroenterologist and a nutritionist to manage symptoms and ensure adequate nutrition, particularly for infants and children. While individuals with some forms of lactose intolerance can still tolerate small amounts of dairy, individuals with hypolactasia may prefer to consume a dairy-free diet to control their symptoms as effectively as possible. Patients with this condition should always report any new or worsening symptoms to their healthcare team, and they may need to attend periodic follow-up appointments.
