Gluten sensitivity includes anyone having a negative reaction to gluten.
Gluten sensitive individuals can have issues ranging from minor annoyances when ingesting gluten to all-out Celiac disease.
People who have gluten sensitivity may have gastrointestinal issues or other annoying symptoms when digesting gluten but may not necessarily have a dramatic change when they eat or stop eating gluten. They may not have to stop eating gluten all together, but may feel better if they cut their consumption down.
Or they may be gluten intolerant, have Celiac disease or Dermatitis Herpetiformis.
