This simple answer?
How long do you think it would it take for 7 different doctors (a psychiatrist, an immunologist, an endocrinologist, a neurologist, a gastroenterologist, a nutritionist, a toxicologist, a sleep specialist) and a biochemist to thoroughly evaluate you, each in their own specialty? Probably a lot longer than 3 and ½ hours! Patients often say “It’s like going to the Mayo Clinic, only better, because all that information is in one doctor!”
The deeper answer:
Over the course of 4 decades in medicine, Dr. Hedaya has learned that most medical sub-specialists are excellent at dealing with ‘train-wrecks’ (e.g., Graves Disease or pneumonia) but wholly inadequate when it comes to recognizing and treating the more subtle areas of dysfunction, which contribute to and cause all manner of chronic illnesses. Because his patients needed help from these subspecialists, but none was forthcoming, Dr. Hedaya took it on himself to learn what he needed to so that he could give people the help they needed. Since the people seeking Dr. Hedaya’s help want to get to the root causes of their problems, Dr. Hedaya believes that a genuine evaluation cannot be partial. It must include a careful and thoughtful assessment of all of the above-mentioned fields of medicine.
