Gluten intolerance, also known as non-celiac gluten sensitivity (NCGS), occurs when a person experiences discomfort after consuming gluten-containing foods, without the autoimmune response characteristic of celiac disease. Symptoms can include abdominal pain, bloating, diarrhea, constipation, headaches, and fatigue.
Celiac disease, on the other hand, is an autoimmune disorder where the ingestion of gluten leads to damage in the small intestine. This can cause serious health complications, as it affects the body´s ability to absorb nutrients effectively. Symptoms are similar to those of gluten intolerance but can be more severe and long-lasting.
