Why I wrote this Book

The goal of this book is to increase your basic knowledge about Irritable Bowel Syndrome (IBS) and potential treatments of this common problem. In this book, I have tried to elaborate on several aspects of this disorder and to answer frequently asked questions. The format of the book is "question and answer" or "Q and A". These are real questions and answers that have been asked by my patients. The format is very similar to what occurs during a typical visit to your physician's office. The language of the book is straightforward to enable individuals with a non-medical background to understand the basic concepts of IBS.

What readers are saying about the book...

For those of us who go to the doctor with a list of questions in hand, this is a great resource if you have IBS or want more information on it. Irritable bowel syndrome is a common disorder of the gastrointestinal tract in which abdominal pain is associated with changes in bowel habits. I Have IBS . . . Now What? was written by Dr. Ashkan Farhadi, a medical doctor and the Director of the Digestive Disease Center at Memorial Care Medical Group in Southern California, and board certified in gastroenterology.

He’s taken questions asked by real patients and collected them in this guide, along with simple, easy to understand answers.  The book is in a question and answer format, which makes it easy to find your particular question first. Then, move on to other questions or just browse the book for information on the causes and nature of IBS; symptoms; identifying the disease (diagnosis); treatments, including alternative ones; foods and IBS, including the “Dynamic Diet,” and more. Other specialists in the field have contributed to the book, answering questions along with Dr. Farhadi, giving their input and expertise. Highly recommended for people with IBS who have questions, or want to help someone else who has IBS. A book like this may offer answers to questions you didn’t realize you had. That’s what makes it an indispensable guide and will make you an effective part of your management team if you have IBS.

This book deepened my understanding of IBS and reinforced the importance of my role in feeling better. I very much appreciated your effort to make clinical information more easily understandable, particularly through the question and answer style and the “real-life” examples. The graphics in the book are helpful and inviting as well. This educational book will not only save time for the doctor and patient, but will also play an important part in helping the person living with IBS to feel more active in their own well-being.

I found the question and answer format to be very helpful. I did appreciate your inclusion of medical terminology. I often find that some patient education texts tend to “dumb down” their information for the average consumer, but I don’t find this practice in your book. The inclusion of actual medical terms is very useful to the patient who may be hearing these terms while in the care of a medical professional.

I have had chronic constipation for 15+ years and found the material in this book very relevant to my situation. The question and answer format is excellent and insightful. You can tell they are based on real questions. I felt like I was having a lengthy conversation with Dr. Farhadi as opposed to reading a book. I am glad to know there are still treatments that can help me even though I have been struggling for so many years. I am optimistic about the future yet realistic after learning how complex the bowel is and how to manage my problem.

It truly is a great book and people like to be aware of what they have in their own words and your book is the perfect solution.

I found it very easy and interesting to read. It reinforces the concept that it’s not just in my “head” so to speak. Your proposition of a Dynamic Diet really clicked for me. I’ve experienced a lot of frustration and anxiety about what I shouldn’t be eating. The fact that I couldn’t find a real solid pattern, just made me feel like I wasn’t looking hard enough.

I loved the book! The book really helped me get a better understanding of my IBS. Now I feel that I am in control not my stomach. It has been a life saver.
— A.A., Chicago, IL
Through this book, I’ve learned that if I control my stress and watch what I can eat, I can lessen the severity and how often I have bouts of IBS. I’ve begun work on taking care of the stress and I watch what I eat. The book is a godsend. It’s as important to me as my bible as it will help keep me from having the painful effects of IBS nearly as often as I have been.
