Non-celiac gluten sensitivity, often shortened to NCGS, describes people who experience symptoms after eating gluten but do not have celiac disease or a wheat allergy.
In other words, testing for celiac disease comes back negative, and allergy testing does not show an IgE mediated wheat allergy. Yet symptoms still happen when gluten is eaten.
Common symptoms include bloating, stomach pain, headaches, fatigue, brain fog, or joint discomfort. Unlike celiac disease, non-celiac gluten sensitivity does not cause the same kind of measurable intestinal damage.
There is currently no single test to diagnose it. Doctors typically rule out celiac disease and wheat allergy first. If symptoms improve on a gluten-free diet and return when gluten is reintroduced, that pattern may point toward NCGS.
For some families, this can feel confusing. The symptoms are real, but the testing does not always give clear answers.
While non-celiac gluten sensitivity is not considered life threatening, it can significantly impact daily comfort. Working with a healthcare provider can help determine whether gluten is truly the trigger and how strict dietary changes need to be.
