We often talk about diabetes on the SDS Support list There are several of us with children who either have diabetes or insulin resistance (like my two boys). There is a known link between CF and Diabetes, here is a link for CF Diabetes info. There is also an article on SDS and Diabetes titled: A case of Shwachman-Diamond syndrome presenting with diabetes from early infancy.
If you would like more information on the article above, please feel free to contact me.
Don't forget that Shwachman-Diamond America has links to over 50 full-text medical articles on Shwachman-Diamond Syndrome. Visit the SDA website and click on th "Mdical Articles" link.
