Symptoms of Gluten Allergy

There is a wide range of symptoms of gluten allergy, also known as gluten intolerance of celiac disease. Since most of the symptoms of gluten allergy are also common to other more widely recognized health conditions, many people don’t even realize they have the condition. Here are some signs to look out for.

Common Symptoms of Gluten Allergy

  • Bloating
  • Abdominal pain
  • Canker sores
  • Diarrhea
  • Constipation

Non-Gastrointestinal (GI) Symptoms of Gluten Allergy

  • Weight loss
  • Stunted growth
  • Iron-deficiency anemia
  • Bone pain
  • Fatigue
  • Thinning hair
  • Itchy skin

But all of these are signs of nutritional deficiencies brought on by malabsorption due to damaged villi.

Neurological Symptoms of a Gluten Allergy

  • Numbness
  • Depression
  • Anxiety
  • ADHD
  • Autism
  • Seizures
  • Dementia
  • Psychotic episodes

Some researchers theorize that these are caused by poorly digested proteins that, due to damage to the intestines (leaky gut), pass into the bloodstream. They are then able to cross the blood-brain barrier and bind to opioid receptors, where they wreak neurological havoc.

Whatever the reason, patients who get off gluten often have remarkable improvements.
