A Complete Approach to Complex and Persistent Health Problems

Osteopath & Private Health Clinics Marlborough & London

The Health Equation provides comprehensive diagnostic assessment and integrated clinical interpretation for patients whose symptoms are persistent, multisystem or difficult to explain.

Led by Mr Gerry Gajadharsingh DO, Osteopath & Diagnostic Consultant in Integrated Medicine, with practices in central London and near Marlborough, Wiltshire.

When the Clinical Picture Remains Unclear

You may already have consulted several clinicians, undergone blood tests or imaging, or received more than one diagnosis—yet still feel uncertain about why you remain unwell or how the different aspects of your health fit together.

Some patients have recognised medical conditions but continue to experience symptoms that are not fully explained by those diagnoses. Others have persistent symptoms despite investigations showing no significant pathology. Many present with a combination of known pathology, possible underlying pathology and disturbances of function or physiological regulation.

The role of The Health Equation is to bring the relevant information together, examine the patient as a whole and help determine appropriate next steps.

Gerry does not replace your GP or medical specialist. Where appropriate, he works alongside and communicates with GPs, consultants and other regulated healthcare professionals.

Key benefits to use The Health Equation

More Than a 60-Minute Appointment

The Diagnostic Consultation is a broader clinical assessment process. Where appropriate, it includes review of records and investigations supplied in advance, a detailed consultation and examination, subsequent clinical analysis and preparation of a comprehensive written report.

The IRSF considers how the respiratory, neural, circulatory, endocrine, immune and inflammatory, metabolic and musculoskeletal systems interact. It helps organise the clinical evidence and identify the factors most relevant to further investigation and management.

Simple or discrete problems may be treated directly. More complex presentations may require staged investigation, osteopathic care, breathing re-education, nutrition, rehabilitation or referral to another clinician.

Clinical Reasoning for Complex Patients

The Integrated Regulatory Systems Framework (IRSF)

Why do some patients continue to experience genuine, persistent symptoms despite extensive investigation, several diagnoses and consultations across multiple specialties?

Drawing on nearly four decades of clinical experience, Gerry Gajadharsingh DO introduces a practical framework for recognising patterns, interpreting physiological relationships and thinking more clearly when the patient does not fit the textbook.
