Gluten is a protein found in wheat, barley, and rye. Some people have Celiac Disease, others have a wheat allergy, and some experience Non-Celiac Gluten Sensitivity. Symptoms can vary widely.
Here are 10 common signs that may be associated with gluten-related problems:
1. Bloating
Feeling unusually full or swollen after eating.
Often occurs after consuming bread, pasta, pastries, or other wheat-based foods.
2. Diarrhea or Constipation
Frequent loose stools or ongoing constipation.
Some people alternate between both.
3. Abdominal Pain
Cramping, discomfort, or stomach pain after meals containing gluten.
4. Excessive Gas
Increased flatulence and digestive discomfort.
Can occur due to poor absorption of nutrients in some conditions.
5. Fatigue
Persistent tiredness despite adequate sleep.
Some people describe feeling mentally and physically drained after eating gluten-containing foods.
6. Brain Fog
Difficulty concentrating.
Forgetfulness, slowed thinking, or reduced mental clarity.
7. Headaches or Migraines
Recurrent headaches that may worsen after certain foods.
8. Skin Problems
Itchy rashes, eczema-like symptoms, or the characteristic rash of Dermatitis Herpetiformis.
Skin may become red, bumpy, and intensely itchy.
9. Joint or Muscle Pain
Unexplained aches, stiffness, or inflammation.
Some people notice improvement when gluten is removed under medical guidance.
10. Iron Deficiency or Other Nutrient Deficiencies
Low iron, vitamin B12, folate, or vitamin D levels.
May cause weakness, dizziness, pale skin, or anemia.
Other Possible Signs
Unexplained weight loss
Mouth ulcers
Numbness or tingling in hands and feet
Mood changes such as anxiety or depression
Fertility problems in some individuals
Poor growth in children

These symptoms are not specific to gluten and can also be caused by conditions such as Irritable Bowel Syndrome, food intolerances, infections, thyroid disorders, or other medical issues.
If you suspect a gluten-related disorder, it’s best to get tested before starting a gluten-free diet. Testing for Celiac Disease can become less accurate after gluten is removed from the diet.
If you’d like, I can also provide a detailed list of foods that contain gluten and foods that are naturally gluten-free.
