Churg-Strauss syndrome is the older name for eosinophilic granulomatosis with polyangiitis (EGPA). EGPA is a rare, immune-mediated disease that can cause inflammation of small to medium sized blood vessels (vasculitis). When blood vessels become inflamed, tissues may not receive normal blood flow, which can lead to symptoms in different parts of the body. EGPA most often affects the airways and lungs, but it can also involve the sinuses, skin, nerves, digestive tract, kidneys, and heart.
How this guide approaches symptom management and diet
This guide focuses on clinically responsible, supportive self-management. EGPA is a medical condition that requires professional diagnosis and treatment, and lifestyle measures should complement-not replace-medical care.
Nutrition and lifestyle choices can still matter. For many people, food and routine changes help with:
Maintaining strength and energy during fatigue
Supporting heart and bone health (especially if steroids are used)
Reducing risk factors like high blood pressure, unwanted weight gain, or blood sugar swings
Making daily eating easier during low-energy or flare periods
Because EGPA experiences vary widely-especially with allergies, asthma triggers, medication regimens, and organ involvement-this guide emphasizes personalization and encourages readers to align changes with their clinician's advice.
In this guide, you will learn...
What EGPA is and how it can affect different organs
Common symptom patterns and practical ways to track them
How clinicians evaluate and monitor EGPA over time
An overview of treatment approaches and what to expect from follow-up care
Everyday strategies for living with EGPA (energy pacing, trigger reduction, and mental health support)
Nutrition principles and meal-planning ideas designed to support overall health and medication side-effect management while staying medically cautious
