A dietitian or nutritionist plays a critical role in concussion rehabilitation by providing expert guidance on nutrition to support brain recovery, manage symptoms, and promote overall health. Their role includes several key areas:

1. Supporting Brain Recovery
   
   Dieticians recommend nutrient-dense foods rich in omega-3 fatty acids, antioxidants, and vitamins (e.g., B vitamins and vitamin D) that support brain repair, reduce inflammation, and improve cognitive function.
   

2. Symptom Management
   
   Concussions often lead to symptoms such as nausea, fatigue, and headaches, which can affect appetite and eating patterns. Dieticians create personalised plans to address these issues, ensuring patients can maintain a balanced diet.
   

3. Vestibular Disorders
   
   Vestibular disorders can cause dizziness, nausea, and motion sensitivity. Dieticians provide recommendations to stabilise blood sugar levels and prevent dehydration, which can exacerbate symptoms. Specific strategies include small, frequent meals, avoiding excessive caffeine, and maintaining electrolyte balance.
   

4. Headache Disorders
   
   Dieticians help identify and manage dietary triggers that can contribute to migraines and tension headaches, such as caffeine, alcohol, artificial sweeteners, processed foods, and histamine-containing foods. They guide patients in adopting an anti-inflammatory diet rich in whole foods.
   

5. Hydration and Energy Balance
   
   Proper hydration and adequate calorie intake are essential for recovery. Dieticians monitor these factors and provide practical strategies to maintain them, especially during reduced physical activity.
   

6. Managing Co-Existing Conditions
   
   If a patient has other health conditions, such as food sensitivities or gastrointestinal issues, dieticians ensure their nutrition plan accommodates these while still supporting concussion recovery.
   

7. Preventing Deconditioning
   
   Reduced activity during recovery can lead to changes in metabolism or weight. Dieticians provide guidance to prevent unwanted weight gain or loss and maintain overall health.
   

8. Long-Term Health Promotion
   
   Dieticians educate patients on the importance of brain-healthy foods and create sustainable eating habits that support long-term well-being beyond the recovery period.
   

9. Practical Meal Planning
   
   They offer practical advice on meal preparation, budgeting, and food selection to ensure patients can implement their nutrition plans easily and consistently.

Through individualised nutrition plans and ongoing support, dieticians play a vital role in helping patients recover from a concussion, manage symptoms, and build a foundation for long-term health.
