    Celiac.com 03/30/2005 – According to Italian researchers, those with lactose intolerance have a much higher incidence of celiac disease. In an effort to determine how many cases could be caused by undiagnosed celiac disease, the researchers screened 54 lactose intolerant patients (15 males and 39 females - positive H2-lactose breath test and a negative H2-glucose breath test) for celiac disease. All patients were screened using serum IgA antibodies to endomysium, anti-transglutaminase and total IgA, and anyone with positive results for any one of these markers was give an upper gastrointestinal endoscopy. The researchers found that a full 24% of those with lactose intolerance had biopsy-confirmed celiac disease. These results were compared to a control group of 50 blood donors from the same region, out of which only 2% were positive--but a follow up biopsy eliminated celiac disease.

    The researchers conclude that a full 24% of patients with a positive H(2)-lactose breath test have celiac disease which is the likely cause of their lactose intolerance, and that anyone with a positive H(2)-lactose breath test should first be screened for celiac disease before excluding milk from their diets.

    Scott Adams was diagnosed with celiac disease in 1994, and, due to the nearly total lack of information available at that time, was forced to become an expert on the disease in order to recover. In 1995 he launched the site that later became Celiac.com to help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives.  He is co-author of the book Cereal Killers, and founder and publisher of the (formerly paper) newsletter Journal of Gluten Sensitivity. In 1998 he founded The Gluten-Free Mall which he sold in 2014. Celiac.com does not sell any products, and is 100% advertiser supported.

    The following is a summary of lactose intolerance which was written by Ellen Eagan eagan@pangloss.ucsf.edu. Ellen is a blood specialist at UC San Francisco Medical Center. Ellen Eagan on Lactose Intolerance:
    The area in the intestines where lactase, the enzyme needed to break down lactose, is produced is called the brush border. It is at the ends of the microvilli. It is only one cell deep. As most people age, their ability to produce lactase decreases. Sometimes it decreases to the point where you are unable to deal with all of the lactose that you ingest. If you have decreased production of lactase and then something else happens to compromise...
