As mentioned in the previous post, there are several ways one can be become lactose intolerant. The reason can be because of genetics, aging, or because of a very rare deficiency that people may be born with.
A large amount of individuals who feel symptoms of lactose intolerance are actually lactose intolerant but believe it or not, there are some people who are lactose intolerant for other reasons. Some may even be temporarily lactose intolerant. One reason why someone may feel the uncomfortable symptoms that come with lactose intolerance is because they suffer from Crohn’s disease or Celiac disease. When someone has Crohn’s disease, they experience severe inflammation in their digestive track, affecting their small intestine. Someone with Celiac disease cannot digest gluten properly, affecting the small intestine as well. The small intestine is where the lactase enzymes are produced. If the small intestine is affected because of these diseases, then there is a high chance individuals with these conditions cannot properly digest dairy products.
Medicine can also affect the small intestine from producing the lactase enzyme. Some medicines have antibiotics that do not let your small intestine to temporarily produce lactase thus leading to uncomfortable side effects when consuming milk during the time of your prescription. Another way one may “become” lactose intolerant would be after having an infectious diarrhea. This condition is more common amongst young children. The diarrhea a child may have nothing to do with dairy, but if the diarrhea is infectious, the child will experience lactose intolerance that is temporary, which develops in days or weeks following the infection from the diarrhea.
Medications and infectious diarrhea triggers temporary lactose intolerance but someone who has Crohn’s disease or Celiac disease are experiencing lactose intolerance due to problems with their digestive system which affect the small intestine.
