It's all in the genes, which accounts for the increase of diabetics, which in its turn, accounts for the market for guides on how to live with it. It seems as if a new one is published every three years and the fact that these sell can be attributed to the need for the diabetic to know almost as much about his own condition and its control as his physician. Unlike the annual crop of books on how to survive with a heart condition, the books for diabetics generally have something new to say to those most concerned; it is a hidden condition often and doctors are continually finding ways to identify it and treat it. These authors take the latest tack in describing the disease as several diseases, give its history from antiquity to the present, use case studies to exemplify the three main types and the diet regimen they demand, and discuss oral and injected insulin programs. Because the book is short and makes complicated information clear for the layman, it appears to be one of the more effective to give to the affected and those who live with them.
