My 26 year old step daughter has had chronic abdominal pain off and on for several years.  Her 8 yr old little sister has celiac disease and had very similar issues before diagnosis and going gluten free... would it be worth getting blood work done to see if my stepdaughter has celiac disease as well?  Both girls have the same biological father.
Hello, Thanks for the query to H. C. M. Forum. Celiac disease is diagnosed her younger sister so note down following things as, Environmental factors play an important role as gluten present in wheat, rye,barley, oats. 2 Immunological components, 3 Genetic factors. As you mentioned that biological father is same, so chances are more of celiac disease. Broad spectrum antibiotic with folic acid tablets are the best treatment, but consult a physician and get in treatment. Hope I have answered your question. If further any question I will help. Best wishes for your daughter.
