A very different sequence occurs if a glandular extract—in this case, insulin—is administered. (Particularly if the orthodox dietetic changes are made, since these increase enormously the overload on the vital organs.) Instead of maintaining a determined effort to become wholesome and self-supporting, the body accepts the foreign material, and to the onlooker the "improvement" is magical. The system stops trying to keep the defective organ in working order. Why should it continue to make so laborious an effort if a working substitute is provided? The last vestiges of activity in the defective organ may fade out within a few months.
The patient is now wholly dependent upon material robbed, with violence, from another creature. The humanitarian aspect is distressing, but no nearly so dreadful as what happens within the patient’s body. Where formerly the system was in a more or less uniform state of toxic saturation and malfunction, we find that a wholly artificial stimulus to metabolic activity has been introduced. That is, the energy which the body allows to be expended on various activities is no longer regulated by the capabilities and reserves of the system as a whole, but by the dosage of the glandular extract. This, in turn, is affected by the food-consumption of the patient and also by the ever-increasing strain on other vital organs. A mad vicious circle is set up and the patient is fortunate indeed who can even hold his own against the forces which are acting in concert for his destruction. A gross misrepresentation? "Diabetes can now be controlled accurately and with complete success" is the claim of the medical school. "Insulin is the most wonderful curative agent of modern times", we are assured. But the inescapable fact is that the death-rate from diabetes has risen rapidly in a very part of the world where insulin is used! A fifty per cent increase in 10 years is this country’s record (1926-36). USA deaths rose 68 per cent between 1922 and 1944.
