Feeling Tired, Bloated, or Foggy? Your Diet Might Be the Missing Piece
Fatigue, bloating, and brain fog are some of the most common complaints people bring to their healthcare providers—but they’re also among the most misunderstood. While these symptoms can have a wide range of causes, one area that’s often overlooked is nutrition.
At The Clinic at Christie in Toronto, we take a whole-person approach to care. Our team of family physicians and registered dietitians works together to explore how your lifestyle, diet, and medical history interact—especially when symptoms don’t have a straightforward explanation.
In this post, we’ll explore how nutrition may be contributing to how you feel, and why working with both a doctor and a dietitian can provide a more complete understanding of your health.
🧠 Understanding the Symptoms: What’s Really Going On?
Many people live with vague symptoms like fatigue or bloating for years, without realizing these could be signs of underlying nutritional imbalances.
Fatigue
Some of the most common nutrition-related causes of fatigue include:
- Iron deficiency, especially common in menstruating individuals or those on plant-based diets (NIH Iron Factsheet)
- Vitamin B12 deficiency, which affects energy and nerve health (NIH B12 Factsheet)
- Poor blood sugar regulation, linked to high-sugar meals or irregular eating patterns (Mayo Clinic: Fatigue Causes)
Bloating
Persistent bloating can be tied to:
- Food intolerances (like dairy or gluten)
- Gut microbiome imbalance, which can affect digestion and absorption
- Ultra-processed foods, which are often low in fiber and high in additives (Cleveland Clinic: Common Causes of Bloating)
Brain Fog
Many people describe feeling mentally “foggy” or unfocused. Possible nutritional contributors include:
- Low omega-3s or key vitamins involved in brain function
- Blood sugar crashes, from skipping meals or high-carb eating patterns
- Chronic inflammation, often driven by poor diet (Harvard Health: Clearing Up Brain Fog)
🥗 The Role of Nutrition in Primary Care
While a family doctor can screen for medical issues like thyroid dysfunction, anemia, or sleep disorders, a registered dietitian focuses on how nutrition may be influencing these conditions.
Working with a dietitian can help:
- Identify nutrient gaps or food sensitivities
- Improve gut health and digestion
- Create a realistic, personalized eating plan
- Address symptoms without medication when possible

👥 Why Collaborative Care Works
One of the key advantages of our approach at The Clinic at Christie is that family doctors and dietitians work together. This means:
- Faster identification of underlying causes
- A more complete picture of your health
- Coordinated care without conflicting advice
For example, a patient with fatigue and bloating may have normal labs, but still feel off. While the doctor rules out major conditions, the dietitian may identify inconsistent eating, low fiber intake, or poor hydration as contributing factors. Together, they develop a plan that addresses both the medical and nutritional pieces of the puzzle.
📝 When to Consider a Dietitian Referral
If any of the following sound familiar, nutrition might be playing a role:
- Persistent fatigue, even with good sleep
- Regular bloating, gas, or stomach discomfort
- Ongoing brain fog or poor focus
- A desire to manage a condition like IBS, PCOS, prediabetes, or thyroid issues more naturally
- Trouble making diet changes that actually stick
Registered dietitians are highly trained, regulated professionals in Canada. You can learn more through Dietitians of Canada and Academy of Nutrition and Dietetics.
