Lactose intolerance is very common among adults, with about 30 million American adults being diagnosed with some level of lactose intolerance by age 20, according to the National Institutes of Health (NIH).

Someone’s ethnic or racial background can make them more or less likely to become lactose intolerant. The condition is most common among people of Asian, African, or Native American descent and among Hispanics and Latinos, according to the NIH.

People of European descent are least likely to be lactose intolerant, according to the NIH.

Babies born prematurely sometimes also can have lactose intolerance, according to the NIH. The condition is hereditary, so most people inherit it from their parents, according to the Food and Drug Administration (FDA).
