Orofacial Granulomatosis (OFG): Symptoms, Diagnosis, Causes & Modern Treatment

Orofacial Granulomatosis (OFG) is a rare but often overlooked inflammatory condition that can present with persistent lip swelling, oral ulcers, gum changes, and facial swelling. Because its symptoms overlap with many other conditions, diagnosis is frequently delayed, leaving patients and families searching for answers.

In this episode of Hope & Histamine: The Paediatric Allergy Podcast, we take a deep dive into the science and clinical management of Orofacial Granulomatosis. We discuss what OFG is, why it develops, and its important associations with Crohn’s disease, allergy, and other inflammatory disorders. You’ll learn how clinicians approach the diagnosis, the role of biopsies and investigations, and the latest evidence-based treatment options available for both children and adults.

Whether you’re a healthcare professional, medical student, patient, or parent, this episode provides a clear, practical, and evidence-based overview of this fascinating condition.

In this episode, we cover:

• What is Orofacial Granulomatosis (OFG)?
• Common signs and symptoms, including persistent lip swelling
• Causes and current theories behind OFG
• The relationship between OFG and Crohn’s disease
• Is allergy involved?
• How OFG is diagnosed and the role of biopsy
• Important differential diagnoses clinicians should consider
• Medical and dietary treatment options
• Long-term outlook and follow-up
• Key take-home messages for patients, families, and healthcare professionals

Join us as we separate fact from fiction and explore the latest understanding of Orofacial Granulomatosis, helping listeners recognise the condition earlier and understand the best approaches to diagnosis and management.
