Medical Advisers

Dr. Johannes W. Dietrich, M.D.

Dr Dietrich is a senior consultant endocrinologist and head of the Diabetes Endocrinology and Metabolism section at the St. Josef Hospital in Bochum, Germany, and of the Diabetes Centre Bochum/Hattingen at the Blankenstein hospital in Hattingen. He received his MD at Ludwig Maximilian University of Munich. He is a senior lecturer in Endocrinology at Ruhr University of Bochum and a specialist in genetic counselling in endocrinology and in stress medicine.
He has always been fascinated by homeostasis, allostasis and other concepts of biomedical cybernetics. He is particularly interested in why and how the logical structures of biological information-processing algorithms relate to their behaviour and that of the embedding organ systems. This motivated him to investigate the hypothalamus-pituitary-thyroid axis.

He has initiated multiple clinical trials. Key results of his work include the development of a mathematical theory of thyroid homeostasis, the development of a simulation program of pituitary-thyroid feedback control (SimThyr) that is today used in more than 100 countries for education and research, and of a mathematical method for calculating the thyroid’s secretory capacity and total deiodinase activity in vivo (SPINA). Additionally, he established the theory of thyroid allostasis in different conditions of stress and illness.

Dr. Johannes W. Dietrich, M.D.

Dr John Midgley has been a University Lecturer, worked in biochemistry/molecular biology.  He went to Leeds and Newcastle-upon-Tyne Universities between 1962-1975.  He was the Clinical Trials Coordinator for Diagnostic Products, Amersham from 1975 to 1988.  He is an inventor of the one-step methodologies for FT3/FT4 measurement (1980 and 1988).  He is a winner of the Prince of Wales Award for Industrial Innovation and Production in 1985 and a consultant of Diagnostic Methodologies (1988-1998) and a Trials Abstractor, Gastroenterology, Cochrane Collaboration, (1999-2006).

He is an independent writer and reviewer for thyroid function test interpretation and author of 120 + papers and reviews on bacterial molecular biology/clinical thyroid function diagnostics.

Dr. Sarah Myhill

Dr Sarah Myhill has a special interest in treating fatigue and in preventive medicine. She believes that many diseases are entirely preventable through good diet and nutrition. Her aim has always been to look for causes of disease and treat by addressing those causes, be they infectious, allergic, nutritional or toxic, or a combination.

Dr Myhill has a website that contains a huge amount of information about thyroid issues as well as CFS and ME.

Dr Myhill has written several books which may be extremely interesting to you.
