9 Signs of a Gluten Allergy

Here are 9 common signs of a gluten allergy or sensitivity that might indicate your body is reacting negatively to gluten (a protein found in wheat, barley, and rye):

1. Bloating
Feeling swollen, full, or gassy after eating — a very common symptom in gluten intolerance.

2. Diarrhea or Constipation
Gluten can cause chronic digestive issues, including loose stools or hard-to-pass bowel movements.

3. Abdominal Pain
Frequent stomach pain or cramps after meals may be linked to gluten-related inflammation.

4. Headaches or Migraines
Some people experience frequent headaches or migraines that improve on a gluten-free diet.

5. Fatigue
Feeling unusually tired, especially after eating gluten, may signal an intolerance.

6. Skin Problems
