This codelist identifies malabsorption syndromes. It is designed for the purpose of the vitamin D study (indications for vit. D testing/ prescribing) and therefore focused on the malabsorption of lipids.

To be used correctly and cover all potential causes of malabsorption, this codelist should be used alongside the following codelists: Coeliac disease, Crohn's disease, Cystic Fibrosis, Pancreatic Insufficiency, Malabsorption due to gastrointestinal surgery.
