Relapsing polychondritis (RP) is a rare autoimmune disorder characterized by recurrent inflammation of cartilage in various parts of the body, including the ears, nose, joints, larynx, trachea, and eyes. This can lead to debilitating changes in appearance and functionality, such as "cauliflower" ears and saddle-nose, and in severe cases, damage to eyesight, hearing, and respiratory health. While the exact cause of RP remains unknown, research suggests that genetic predisposition combined with environmental factors, including diet, may play a significant role in triggering autoimmune conditions.
Understanding Relapsing Polychondritis
Relapsing polychondritis (RP) is a rare autoimmune disorder affecting 0.71 to 3.5 people per million each year. It leads to repeated episodes of inflammation in the body’s cartilage, affecting areas like the ears, nose, larynx, trachea, eyes, joints, kidneys, or even the heart. RP occurs equally in men and women across racial backgrounds, with a slightly higher prevalence among women, and typically manifests between ages 40 and 50, though it can appear at any age. Up to 30% of RP cases occur alongside other connective tissue disorders. Due to its remitting, variable nature and non-specific early symptoms, RP often goes undiagnosed for years, averaging about 2.9 years.
Diagnosis of RP
There is no specific blood test for RP. Diagnosis is based on clinical signs and may involve biopsies or imaging. Patients typically meet at least three of six criteria:
- Recurrent chondritis of both ears (up to 90% of cases)
- Nonerosive inflammatory arthritis (50-85%)
- Chondritis of nasal cartilage (53%)
- Inflammation in ocular structures (50-60%)
- Respiratory tract chondritis (laryngeal, tracheal cartilage)
- Cochlear or vestibular damage, such as hearing loss or vertigo
Conventional Treatment Options
Due to the rarity of RP, there is no one-size-fits-all treatment plan. Options depend on symptom severity. Mild cases may be treated with glucocorticoids (e.g., prednisone) or dapsone. More severe cases might require immunosuppressants, such as methotrexate or cyclophosphamide. Some patients may also receive biologic drugs (medications that target the immune response) like Infliximab. Surgical options like airway stenting, dilation, tracheostomy, or reconstruction may be necessary in cases of airway collapse.
The Role of Diet and Lifestyle in Managing RP
Although research specifically linking diet to RP is limited, the broader scientific community increasingly recognizes the significant role of diet and lifestyle in managing autoimmune conditions. An anti-inflammatory diet, along with other lifestyle adjustments, can potentially reduce flare-ups, improve symptoms, and enhance overall health.

The Anti-Inflammatory Diet
An anti-inflammatory diet emphasizes whole, unprocessed foods that are believed to interfere with the inflammatory process. While there is no single anti-inflammatory diet plan, the general principles include:
- Emphasis on Plant-Based Foods: A wide variety of fruits and vegetables, minimally refined whole grains, herbs, and spices.
- Healthy Fats: Unsaturated fats such as those found in olive oil, avocados, nuts, and oily fish.
- Limited Processed Foods: Minimizing processed meats, saturated fats, refined sugars, salt, and white flour.
Specific Dietary Recommendations
- Plant-Based, Gluten-Free Approach: Focus on whole foods, avoiding animal products, dairy, oil, and gluten.
- High Fiber Intake: Emphasize high-fiber, high-raw, plant-based meals rich in antioxidants.
- Elimination Diet: Identify and eliminate specific foods that trigger flare-ups.
- Avoidance of Alcohol: Limit or eliminate alcohol consumption.
Scientific Support for Dietary Approaches
Several studies support the benefits of a plant-based, gluten-free diet for autoimmune conditions:
- A plant-based diet can reduce inflammation, joint swelling, BMI, and improve gut health.
- A very low-fat, vegan diet may improve symptoms in patients with autoimmune arthritis.
- A raw vegan diet high in antioxidants and fiber has been shown to reduce joint stiffness and pain.
Additional Lifestyle Considerations
In addition to dietary changes, several lifestyle factors can influence the management of RP:
- Regular Routines: Maintain regular sleep patterns and daily routines.
- Adequate Sleep: Prioritize quality sleep to support immune function.
- Smoking Cessation: Avoid smoking, as it can exacerbate inflammation.
- Physical Activity: Engage in regular physical activity to maintain strength and mobility.
- Sun Exposure: Obtain adequate sun exposure for vitamin D production.
- Probiotics: Consider probiotics, especially strains like Lactobacillus rhamnosus, to support gut health.
- Stress Management: Practice stress management techniques such as yoga, meditation, and mindfulness.
- Environmental Triggers: Avoid environmental triggers such as toxins, mold, GMOs, pesticides, viruses, bacteria, fungi, food additives, and plastics.
- Medication Awareness: Avoid unnecessary antibiotics and other medications that may cause inflammation.
- Vaccination Considerations: Exercise caution with unnecessary vaccines, including the Covid vaccine.
- Positive Relationships: Foster positive relationships to support overall well-being.
The Gut-Inflammation Connection
A growing body of research highlights the connection between gut health and inflammation. Abnormal levels of bacteria in the gut (dysbiosis) and increased intestinal permeability ("leaky gut") have been observed in inflammatory conditions. When the intestinal barrier is compromised, bacteria, viruses, toxins, and allergens can escape into the bloodstream, potentially triggering inflammation and disease.
Strategies to Improve Gut Health
- Fiber-Rich Diet: Increase fiber intake to promote a diverse and beneficial gut microbiome.
- Prebiotics and Probiotics: Consume foods rich in prebiotics and probiotics, or consider probiotic supplements.
- Nutrient Support: Ensure adequate intake of nutrients like glutamine and tryptophan, which can help improve intestinal barrier function.
Practical Steps to Implement Dietary and Lifestyle Changes
- Consult Healthcare Professionals: Work with a rheumatologist, registered dietitian, or other healthcare providers to develop a personalized treatment and management plan.
- Gradual Dietary Changes: Gradually incorporate more plant-based foods into your diet while reducing processed foods, animal products, and potential allergens.
- Meal Planning: Plan meals and find recipes that incorporate anti-inflammatory foods.
- Monitor Symptoms: Keep a food journal to track symptoms and identify potential trigger foods.
- Stay Informed: Stay updated on the latest research and management strategies for RP.
