Lactose Intolerance and Coeliac:

As you start to heal on a gluten free diet, your intestines will begin to absorb all the nutrients from food that they were missing out on before. This can be quite a shock to the body and you may develop a temporary allergy to certain foods. It is sometimes a good idea to be tested for lactose intolerance, yeast intolerance and even allergies to certain sugars. Otherwise its all about trial and error. Just remember that lactose intolerance when brought on by a gluten free diet is usually temporary and you will more than likely be able to ease back into drinking that glass of milk again! :)
