Non-Celiac Wheat Sensitivity (NCWS) is a condition where people have symptoms similar to celiac disease, but they don't have the same immune response. This study wants to find out if NCWS is a permanent condition or if it can go away over time. People with NCWS may have been diagnosed by a test called a double-blind placebo controlled (DBPC) challenge, which involves not knowing if you're eating wheat or a placebo to see if symptoms appear.

Researchers are looking at people who were diagnosed with NCWS between 2001 and 2011 to see how many are still avoiding wheat and if the condition persists. This is important because while celiac disease is lifelong, we don't know if NCWS is the same.

• The study will involve patients previously diagnosed with NCWS using a DBPC challenge.
• Researchers will check if participants still need to avoid wheat or if their symptoms have changed.
• Participants will be monitored over time to understand the persistence of NCWS.
