Читать книгу Diabetes For Dummies - Рубин Алан Л. - Страница 2

You’re reading the 5th edition of Diabetes For Dummies, and you may be wondering why another edition is necessary. The previous edition (published in 2012) had everything you needed to know to reverse the plague of diabetes, yet the problem seems to be increasing, not decreasing. Following are some of the possible explanations for this situation:

✔ Not enough people bought the last edition of the book.

✔ Even if they bought it, not enough people followed the recommendations in the book.

✔ Too many people aren’t even aware that this book exists.

✔ No book or books can stop an avalanche after the snow starts rolling downhill.

✔ Some new information, not available three years ago, may be able to make a major difference toward reversing diabetes, especially the information in Chapter 9.

The real answer is actually all of the above (and probably more reasons).

The Centers for Disease Control and Prevention recently suggested that as many as one in three adults in the United States will have diabetes by the year 2050. The International Diabetes Federation reports that 387 million people had diabetes in 2014 and that 552 million will have the disease by 2030 – that’s one in every ten people on the earth. In a previous edition of this book, I set this figure at 366 million by 2030, so you can see that today’s predictions are even more dire than those of four years ago. This increase is because the population is aging, minority groups who have a higher risk for diabetes are increasing, and, fortunately, people with diabetes are living longer. However, these numbers are based on past trends. The prediction will not turn out to be true if people improve their lifestyle choices through the means discussed in this book.

Over the last decade, a large study was performed in Germany to see if lifestyle change could make a difference. Four major factors were evaluated in over 23,000 Germans. The factors were

✔ Never smoking

✔ Body-mass index less than 30

✔ Exercising for three and a half hours or more a week

✔ Following healthy dietary principles: high intake of fruits and vegetables, eating whole-grain bread, and low meat consumption

The happy finding was that the more factors a person followed, the lower the risk of major chronic diseases, including heart disease, diabetes, and cancer. People who followed all four had a 78 percent lower risk of those diseases than people who had no healthy factor. People with three factors were a little less protected, with two a bit less and with one even less but still better than no factors at all.

About This Book

So much has changed in the three years since the fourth edition of Diabetes For Dummies was written that a fifth edition was clearly necessary. I need to tell you about new medicines (see Chapter 11), new glucose meters (Chapter 7), and new ideas about diet and exercise and curing diabetes with surgery (Chapters 8, 9, and 10). I also need to share new information about diabetes in children (Chapter 13) and the occupational and insurance problems of people with diabetes (Chapter 15). Just about every chapter has something new, especially (obviously) Chapter 16, which deals specifically with what’s new in diabetes care.

A new edition also gives me the opportunity to thank the thousands of people who have thanked me for Diabetes For Dummies. You have given me a sense of enormous gratification for writing this book. You have shared your stories with me, permitting me to laugh and cry with you. One of the best is the following from Andrea in Canada:

My 3-year-old daughter was recently diagnosed with diabetes type 1. It has been a rough time. To help us out, my brother and his wife bought us your book, Diabetes For Dummies. One day my daughter saw this bright yellow book and asked what I was reading. I told her Diabetes For Dummies. As soon as the words came out of my mouth, I regretted it. I didn’t want her to think that dummies got diabetes so I quickly added, “I am the dummy.” Without missing a beat, she then asked, “Am I the diabetes?”

The story doesn’t just end there. The other day she was relaxing on the couch. She looked at me and said, “I don’t want to have diabetes anymore.” Feeling terrible, I responded, “I know sweetie; I don’t want you to have it anymore either.” I then explained that she would have diabetes for the rest of her life. With a very concerned look she then asked, “Will you be the dummy for the rest of your life?”

As sad as it is, I guess you’re right, one must look for humor in everything; otherwise we would have broken down by now.

You’re not required to read this book from cover to cover, although if you know nothing about diabetes, reading straight through may be a good approach. This book is designed to serve as a source for information about the problems that arise over the years. You can find the latest facts about diabetes and the best sources to discover any information that comes out after the publication of this edition.

Throughout this book I use some specific conventions to make the text clearer, to highlight information, and to make your read as effortless as possible. These conventions are important to know, so I list them here:

✔ Sugar versus glucose: Diabetes, as you may know, is all about sugar. But sugars come in many types. So doctors avoid using the words sugar and glucose interchangeably. In this book (unless I slip up), I use the word glucose rather than sugar. (You may as well get used to it.)

✔ Emphasis on type 2 diabetes: There are a number of different types of diabetes (see my explanation in Chapter 3), and the most common are type 1 diabetes and type 2 diabetes. Because I recently published Type 1 Diabetes For Dummies (John Wiley & Sons, Inc.), most of what you read here is about type 2 diabetes.

✔ Abbreviations: To save time, I use the following abbreviations:

● T1DM: Type 1 diabetes mellitus (formal name of type 1 diabetes)

● T2DM: Type 2 diabetes mellitus (formal name of type 2 diabetes)

✔ Pharmaceutical drug names: When I mention a drug used in the treatment of diabetes, I give the generic name. I provide the trade name in parentheses if relevant.

Foolish Assumptions

The book assumes that you know nothing about diabetes. So you won’t have to face a term that you’ve never heard of before and that is not explained. For those who already know a lot about diabetes, you can find more in-depth explanations in this book as well. You can pick and choose how much you want to know about a subject, but the key points are clearly marked.

Beyond This Book

In addition to the content of this book, you can access some related material online. I have posted the Cheat Sheet at www.dummies.com/cheatsheet/diabetes. It contains important information that you may want to refer to on a regular basis. I also share some additional bits of information and pointers at www.dummies.com/extras/diabetes that can help you navigate this medical condition. You can find a glossary as well as a reference guide for additional help you can find online to deal with your diabetes.

Where to Go from Here

Where you go from here depends on your needs. If you already have basic knowledge of diabetes and want to know more about complications, go to Chapter 3. If you are a novice, start at Chapter 1. If you want to know more about the medications you are taking, go to Chapter 11. Each chapter title clearly tells you what you can find there, so check the table of contents to find what you need rapidly.

As you’ll find out, keeping a positive attitude and finding some humor in your diabetes can help you a great deal. At times you’ll feel like doing anything but laughing. But scientific studies are clear about the benefits of a positive attitude. In a very few words: He who laughs, lasts. Another point is that people learn more and retain more when humor is part of the process.
