What’s Triggering Your Fatigue, Skin Issues, or Brain Fog? It Might Be Your Gut

Written By Angela Andrews, MD

Tired, bloated, anxious after eating?
You might be dealing with a food sensitivity—a delayed, subtle immune response that can affect your gut, skin, joints, or mood days after you eat the food.

👀 Most commonly reactive food:

  • Gluten

  • Dairy (casein and/or whey)

  • Eggs

  • Soy

  • Corn

  • Nightshades (tomatoes, peppers)

  • Additives (e.g., food dyes, preservatives)

🌀 Common symptoms:

  • Fatigue or brain fog

  • Eczema, acne, or rashes

  • Headaches or joint pain

  • Mood changes or anxiety

  • Bloating, gas, irregular stools

🧠 Food sensitivities often reflect deeper immune or gut imbalance. Elimination diets are commonly used to identify intolerances. More controversial testing is available, and despite varying opinions, such tests can be invaluable in the properly selected patient.
