Lactose intolerance. Know the contributing factors.

photo of bottles of almond, rice and soy milk on a wooden backgroundWe have written several times here about the condition known as lactose intolerance. Being lactose intolerant means the body has difficulty breaking down and digesting the sugar in milk, also known as lactose. The condition is caused by a deficiency in the enzyme lactase which is produced in the small intestine. Those who are lactose intolerant do not have enough lactase available to digest lactose, resulting in stomach upset when certain dairy products are eaten. Approximately 30 minutes after eating or drinking, diarrhea, gas and bloating occur. The condition, which is also called lactose malabsorption, is usually harmless, but its symptoms can be uncomfortable. The symptoms are similar in adults, toddlers, and infants.

According to the National Digestive Diseases Information Clearinghouse, over 30 million American people over the age of 20 are lactose intolerant.

It’s important to understand certain factors contribute to lactose intolerance. Among them are:

  • Infection. After a bout of infectious diarrhea, some children develop a temporary lactose intolerance that usually improves after a few days or weeks,
  • Increasing age. Lactose intolerance usually appears in adulthood. The condition is uncommon in babies and young children.
  • Ethnicity. Lactose intolerance is most common in people of African, Asian, Hispanic and American Indian descent.
  • Premature birth. Infants born prematurely may have reduced levels of lactase because the small intestine doesn’t develop lactase-producing cells until late in the third trimester.
  • Diseases affecting the small intestine. Small intestine problems that can cause lactose intolerance include bacterial overgrowth, celiac disease and Crohn’s disease.
  • Certain cancer treatments. Radiation therapy for cancer in the abdomen or intestinal complications from chemotherapy, lead to an increased risk of lactose intolerance.
