Reviews from pediatric health care professionals and selected parents are below.
This is a marvelous book that desperately needed to be written. It is written in simple straightforward language, but all the information is there. Functional constipation is a condition where knowledge really is power. I can’t tell you how often, in working with parents I’ve heard “He can’t be constipated. He goes every day.” There is so much misunderstanding around this condition. Dr. DuHamel does everyone a great service in demystifying the whole process of functional constipation and then breaking down the solution into simple steps that lead to recovery.
This book should be of great help to parents, children and those that serve them.

As a doctor who specializes in the intestinal problems of children, I have often wished for a book like this to offer to families whose children suffer from functional constipation. I fully endorse this book and commend Dr. DuHamel for doing such a wonderful job of making it easy to read and helpful for families and medical professionals alike.

A significant number (approximately one third to one half) of adults with functional gastrointestinal disorders report having abdominal pain and bowel problems as children. This book will be very useful to parents and children in learning strategies early in life that may reduce or prevent the long term impact of functional constipation in their adult years.

Before we met Dr. Tom, accidents, hidden underwear, discussions about whether or not he had really gone to the bathroom and bedwetting were all part of daily life for our almost nine year old son. He was initially unenthusiastic about talking to yet another doctor, but being an active participant in deciding how much medicine he needed and what he could do to control his bedwetting really helped him feel more in control. Now, just seven months later, my son no longer soils his underwear or wets the bed and he can do sleep-overs without fear of accidents. We have also seen a huge boost in his self esteem. His success on Dr. Tom’s program has been truly amazing.

Chronic constipation and toilet resistance in children is a major source of concern and frustration to parents. To the pediatrician and family physician, the care of this condition demands extensive time in the office and on the phone. Dr. DuHamel has created a clear, logical and effective guide to help both the parent and practitioner treat and correct this challenging problem. The Ins and Outs of Poop is not just another toilet training book. It is a unique and positive manual in dealing with one of pediatrics most common and least discussed problems.
—Gary B. Spector, MD, Pediatrician
After dealing with GI issues for six long years, we were shocked to see such a quick turnaround. In just a small period of time on this program, our son started pooping regularly once a day. He has been happier and more confident, which makes our lives much less stressful. It has been a miracle!
—Stiroh Lang, Parent
The Ins and Outs of Poop provides clinicians with a manual for how to deal with the unfamiliar world of childhood functional constipation. As Dr. DuHamel explains, issues related to withholding or stool incontinence can be misinterpreted as being related to an emotional disturbance. Clinicians and parents will learn that withholding and stool incontinence are not willful behaviors and, in most cases, the child is not intending to be defiant. This book sheds light on the etiology of functional constipation as well as effective treatment strategies. Parents no longer need to feel hopeless about their child’s toileting issues. I have used the six-step program with many of my patients who have sought treatment for functional constipation. I can attest to its efficacy and the relief parents and children feel when this problem no longer dominates their lives.
—Lauren Silvers, PhD, Clinical Psychologist
Constipation is a problem that presents often in my clinical pediatric practice. It is extremely frustrating for parents, children and, at times, providers. Dr. DuHamel’s book is an excellent resource that covers all aspects of this issue. It is concise and well organized.
In my 30 years of practice, I have rarely come across a book that is so thorough and user friendly. I envision using this book frequently when working with these families. I would strongly recommend The Ins and Outs of Poop as an invaluable addition to nurse practitioner’s and physicians personal libraries.
—Nancy Lockett, ARNP, MS, Maternal Child Health
The Ins and Outs of Poop is a one stop resource for pediatricians, clinicians, and parents dealing with children suffering from constipation. Dr. DuHamel provides a proven treatment blue print. He details the underpinnings of constipation, anticipates potential roadblocks that can occur in treatment, and offers strategies as to how to successfully navigate them. I have incorporated the six-step approach into my practice and find it to be an essential tool for educating parents, successfully treating the child’s constipation, and reducing family stress. The Ins and Outs of Poopis the definitive guide for addressing childhood constipation.
—Paul S. Lapuc, PhD, Clinical Psychologist
This excellent little book is packed with useful information, logically presented, and accompanied by many helpful tables and illustrations. Even though, as a general internist, my practice did not include children with chronic constipation, I certainly found much in the book’s presentation of diagnostic and therapeutic principles that would be applicable to the treatment of adults with chronic constipation. Many readers, including health care providers and parents of children with chronic constipation, will find The Ins and Outs of Poop to be a valuable resource.
