Lactose intolerance in infants (congenital lactase deficiency) is caused by mutations in the LCT gene. The LCT gene provides the instructions for making lactase. Mutations are believed to interfere with the function of lactase, causing affected infants to have a severely impaired ability to digest lactose in breast milk or formula. [19]

Secondary lactose intolerance results from injury to the small intestine, such as from infection, celiac disease, inflammatory bowel disease or other diseases. [ 43 ] [ 44 ] Developmental lactose intolerance may occur in premature babies and usually improves over a short period of time. [ 43 ]
Lactose can not be absorbed by the intestine and needs to be split in the small intestine into galactose and glucose by the enzyme called lactase; unabsorbed lactose can cause abdominal pain, bloating, diarrhea, gas, and nausea. [citation needed] In most mammals, production of lactase diminishes after infants are weaned from maternal milk.
Food allergies affect mostly young children, and approximately 90 percent of these allergies are caused by just eight foods: cow's milk, eggs, soy, peanuts, tree nuts, wheat, fish, and shellfish.
This is an autosomal recessive disorder and infants that can’t break down lactose have trouble with breastmilk, and develop diarrhea starting from birth. Sometimes, even those with lactase-persistence can develop temporary lactose intolerance as a result of infection or inflammation in the small intestine.
Lactose intolerance occurs when an individual is deficient in the enzyme lactase, which breaks down the lactose in the intestine. Bloating, cramps, constipation, or diarrhea may result when an individual who is lactose intolerant consumes a dairy product. Due to genetic differences, [22] [23] intolerance of lactose is more common globally than ...
Not all questions have simple, yes or no answers—including this one. While many dogs are lactose intolerant, many are not! Lactose intolerance develops as a dog grows up, so it can be impossible ...
