Co-occurring Conditions

This section is dedicated to helping individuals in our community learn more about commonly seen co-occurring conditions; we believe all providers should be aware of the relationships and screen for these conditions when indicated. Our team is still working on completing these sections, but we expect to have them all completed by December 31, 2025.

  • Ehlers-Danlos Syndrome

  • Hypermobile Ehlers-Danlos Syndrome (one type of EDS)

  • Mast Cell Activation Syndrome (MCAS)

  • Hypermobility Spectrum Disorder

  • Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)

  • Inappropriate Sinus Tachycardia

  • Vasovagal Syncope

  • Orthostatic Hypotension

  • Sjögren Syndrome

  • Celiac Disease

  • Autoimmune Thyroiditis
