Dr Fearn’s approach is to thoroughly evaluate a patient’s presenting symptoms and previous investigations before considering investigations to exclude ongoing, potentially progressive underlying pathology. Subsequent management involves considering the physiological processes and mechanisms (such as nutritional factors and intestinal physiology) that can contribute to symptoms even in the absence of underlying disease. Working with a multidisciplinary team including dietitians and clinical scientists the aim is to manage symptoms through modifying a combination of medical and non-medical factors.
