Fatigue
It's quite common to feel tired, and it's often not a sign of any disease. However, you should consider the possibility of an underlying problem if you consistently feel extremely fatigued. People who are gluten intolerant are highly prone to feeling fatigued, especially after eating gluten-containing meals.
After eating gluten, a protein found in the grains wheat, rye, barley, and triticale, one may experience fatigue. This symptom might indicate celiac disease or gluten intolerance. The immune response caused by eating gluten may make it difficult for sensitive people to properly absorb nutrients. Your brain, neurological system, and organs are deprived of the nutrition they require as a result. The lack of nutrition is the cause of your fatigue, and you could also have headaches. One study found that 64% of the 486 non-celiac gluten-sensitive subjects experienced fatigue.
