1. FOGGY MIND
One of the most surprising gluten intolerance symptoms, foggy mind, is pretty subtle. This can be a mysterious symptom since there are so many issues that cause it. But this is a common symptom of celiac disease and gluten intolerance.

2. UNUSUAL WEIGHT GAIN
The unexplainable weight gain causes confusion in many people who are gluten-intolerant.

People who eliminate gluten from the diet usually return to their normal weight.
