Dr. Pastore dives into the prevalence of lactose intolerance in celiacs, and celiac disease in those with lactose intolerance.


In this episode, he covers:

-What a lactose intolerance is and how is it different from a milk/dairy allergy or sensitivity

-68% of the adult population has a lactose intolerance, but who is most at-risk: https://ghr.nlm.nih.gov/condition/lactose-intolerance#statistics

-How lactose intolerance is traditionally diagnosed, and what celiacs should do after being diagnosed to be tested for lactose intolerance (H2-lactose breath test)

-The genetic testing for lactose intolerance (MCM6-RS4988235 - C or CC allele) 

-Why you should get tested for celiac disease if you have a lactose intolerance. In a study done by Ojetti in 2005, 24% had celiac disease with lactose intolerance presenting as their ONLY symptom: https://www.karger.com/Article/Abstract/84526

- What other medical conditions may be causing “secondary lactose intolerance” - your body produces lactase, but something else isn’t right in your digestive tract
