Gluten sensitivity, also known as non-celiac gluten sensitivity (NCGS), is a condition where individuals experience adverse symptoms after consuming gluten, a protein found in wheat, barley, and rye. Unlike celiac disease, which involves an autoimmune response, gluten sensitivity does not cause damage to the intestines but can lead to discomfort, including bloating, fatigue, and headaches. Diagnosis of gluten sensitivity is often challenging, as there are no specific tests. People may find relief by eliminating gluten from their diet, but it is essential to consult a healthcare professional for proper evaluation and guidance. Understanding gluten sensitivity can help individuals manage their symptoms effectively.
