Gluten sensitivity refers to a condition in which an individual experiences adverse reactions when consuming gluten, a protein found in wheat and other grains. This can lead to symptoms such as bloating, abdominal pain, diarrhea or constipation, headaches, joint pain, skin rashes, and fatigue. Unlike celiac disease, which is an autoimmune disorder that damages the intestines when gluten is consumed, gluten sensitivity does not cause physical damage to the digestive system but can still lead to a range of unpleasant symptoms. The exact cause of gluten sensitivity is unknown and it is often difficult to diagnose as many of its symptoms are similar to those of other conditions. However, individuals with this condition may find relief by following a gluten-free diet.
