Subtle Signs Your Body Might Be Reacting Badly to Gluten

23. Hair Loss or Thinning Hair

Unexpected hair loss or thinning could be a symptom of gluten intolerance, particularly if it is tied to an autoimmune reaction. When the body perceives gluten as a threat, it may attack the hair follicles, leading to excessive shedding. Many people with undiagnosed gluten intolerance also have nutrient absorption issues, particularly with iron and B vitamins, which are critical for hair growth. If your hair is falling out without explanation, it’s worth considering whether gluten could be interfering with your body’s ability to absorb essential nutrients.

24. Unexplained Low Vitamin and Mineral Levels

Even with a healthy diet, some people struggle with persistent nutrient deficiencies, such as low iron, vitamin D, magnesium, or B12. This is because gluten can cause intestinal damage or inflammation that impairs nutrient absorption. If blood tests reveal ongoing deficiencies despite taking supplements or eating a nutrient-rich diet, it may be time to consider whether gluten is interfering with your gut’s ability to absorb what your body needs.
