Mermaid Central Medical Clinic Research

Sharing research in Long COVID, POTS, fibromyalgia and other areas

Welcome to MCMC Research

Introduction to Long Covid....

This website is intended to summarise our current research on the aetiology and management of Long COVID and POTS.  It is our hope that these findings may enable physicians to “join the dots,” to help their patients now, often with conservative measures such as physical therapy, dietary change, and medications that have a well-established safety profile and are often available without a prescription.


It is though, like opening Pandora’s Box. The information in these documents is based on research from around the world coupled with Dr Vittone’s DNA findings, and over 10 years of personal research into Postural Orthostatic Tachycardia Syndrome (POTS.) It utilizes work especially from Griffith University into Chronic Fatigue, from Lawrence Afrin and cohorts in Mast Cell Activation Syndrome, Kjetil Larsen in Thoracic Outlet Syndrome, with assistance from a multitude of colleagues, mostly based on the Gold Coast.

About: Dr Graham Exelby

Graduated from University of Queensland in 1973, working in Southport then Charters Towers, Mt Isa then Texas (Qld) before returning to the Gold Coast in 1978 at Mermaid Beach.  He was joined by Jack Ashwin in 1985, and they built the Mermaid Central Medical Clinic which opened in 1991.   The Clinic now welcomes his daughter Leigh as a GP.

His primary areas of interest are Long Covid, POTS and their co-morbidities, especially migraine, IBS and fibromyalgia.   He has been researching POTS and Fibromyalgia for over 10 years, and now works with Dr Valerio Vittone (Ph.D) in DNA and disease association, Mr David Haynes in Kiiko Matsumoto acupuncture in management of autonomic instability, and has 12 years of cardiovascular research with emphasis on retinal photography and carotid intimal thickness as tools to improve risk assessment.  This has been now shown to be applicable to monitoring cardiovascular risk in Long Covid.

His particular speciality is linking the various DNA mutations, in particular mast cell mutations, with dietary, mechanical and other factors that affect the autonomic system (dysautonomia), craniovascular dysfunction and glymphatic dysfunction.
This complex system has particular relevance in the research that is commencing around the world into glymphatic dysfunction in Alzheimers and Parkinson’s Diseases.
