Gluten intolerance, also known as non-celiac gluten sensitivity, is a condition where individuals experience discomfort after consuming gluten, a protein found in wheat, barley, and rye. Symptoms can include bloating, stomach pain, fatigue, and headaches. Unlike celiac disease, which is an autoimmune disorder, gluten intolerance does not cause damage to the intestines. People with gluten intolerance often find relief by avoiding gluten-containing foods. This means they need to be cautious about what they eat, choosing alternatives like gluten-free bread and pasta. Understanding gluten intolerance can help individuals manage their symptoms and improve their overall well-being.
