Patient Testimonials

“I was diagnosed with ulcerative colitis in May, 2000. My problems started a few years before this when I mistreated my body by not eating well while under quite a lot of stress. I remember when I was at university and had to attend lectures being unable to sit in a class for even five minutes because I was going to the toilet more and more each day. I found it very embarrassing and I couldn’t explain what was happening. The funny thing now when I look back is that I now know where every single toilet is on the London Underground. The unknown fear of having accidents and not making it in time to a toilet was overwhelming. I saw several doctors about my constant need to go the toilet with bleeding and they told me to stop eating chilies! I did not stop.

In a very sick condition I went back home to my family and saw my family doctor. He prescribed anti-diarrhea medication which did absolutely nothing. The doctor then gave me daily blood tests which showed that my iron level was dropping at a very scary rate. I was admitted into hospital looking as white as a sheet and feeling lifeless and confused. After doing tests and after my first colonoscopy they told me I had ulcerative colitis. My entire large bowel was ulcerated and bleeding.

The first thing they gave me was a blood transfusion. The nurse spilled half of the bottle on the floor. Then followed intravenous steroids which caused me to want to eat nonstop. In the hospital I had my own private room which didn’t feel so daunting as I had a in-suite bathroom, but, nevertheless, I was going through hell. I stayed there about five weeks in total. I remember surgeons coming to chat to me about the possible consideration of removing my entire bowel. I couldn’t ever let them do that. Over time I was put on lots of drugs: prednisone, asacol and Aziathriopine Nothing was working! The consultant recommended surgery which frightened me, so I took new action.

I went home and I Googled “self-help / healing colitis.” Then I came across Dr. Klein’s website.  I marveled about how he healed himself and thought I had nothing to lose. I was sick and tired of feeling like this and wasn’t able to enjoy my food because of the pain. I ordered Dr. Klein’s book and started!

It was a shock to go from eating what I called a “normal diet.” I invested in a juicer and, implemented a mostly juice diet and starting eating fruit. I threw away my meds and believed this would work. I didn’t tell my consultant at all. Every time I went back to see him I was a little bit better. I had never done anything as challenging as this. I tried to follow the diet as best as I could.

After a year and a half I went back to see my medical consultant who thought I was taking the meds he had prescribed—I was not. After the examination he told me I had healed—he was amazed, believing it was the drugs. I confessed to him that I hadn’t had any meds for almost two years, and he thought I was lying. He now remembers me as his miracle patient!
I can say that now I don’t follow the diet completely but it really did save me. Thank you Dr. Klein!”

-Pam Johal, Southamptom, England (2011)


“Thank you very much from the bottom of my heart for your book. After struggling with ulcerative colitis for ten years, I implemented the vegan healing diet suggested in your book. After two weeks, the bleeding stopped without any medications. Today, my stools are formed.

I can’t thank you enough. I now understand why everything else I tried before did not work and am confident that I can get my vibrant health back…it is only a matter of time. May God bless you and your family. Thank you.”

-Neelam G., California (2011)


“These testimonials are exactly what people like myself (eight years with UC) need to inspire us, giving us a ‘kick in the ass!’ They are the motivational, truthful, driving force behind the necessary drastic lifestyle changes that we must make in order to heal ravaging diseases.

As a client, I can confidently tell you that the best way to help yourself and others is to buy Dr.  Klein’s books. In my opinion, Dr. Klein is the ‘Grand Master of Digestive Healing.’ Please use the info he has so diligently put together over the years from to his own experience healing UC and many clients’ IBD healing experiences as well.

There is no secret to healing—it just takes hard work with a commitment to living better than you ever have! Listen to Dr. Klein and to those who have been healed or are on their way to becoming healthier than ever. I can say with extreme confidence that my mentor, Dr. Klein, has saved my colon and possibly my life. I definitely have a much better quality of life since studying his works and am happy to shout out the good news at every opportunity. Never give up—we can be cured!”

-Charlie VanKirk, Las Vegas, Nevada (2011)


“I just ordered another paperback for my Mom back in the States and will probably order another one for my Dad soon. Neither have colitis, but your book is so invaluable for anyone suffering from living and eating improperly.

I’m your original e-book purchaser from years ago. Living in Mexico I was suffering with colitis. Unable to easily receive postal mail, I was so appreciative that you agreed to sell me a PDF copy of Self Healing Colitis & Crohn’s, which you said you had not done before. It’s good to see that you now offer the e-book as an option.

Your book is invaluable. It changed my life tremendously. I’m actually thankful that I was stuck in Mexico with no money or health insurance while in my 40s and suffering from colitis pain. If I had health insurance I might never have been forced to find an alternative method of healing. After three weeks on your healing program I was free from pain and after four weeks had lost 30 unhealthy pounds.

Thanks, again, for helping me out and for writing the second most important book in the world.”

-John M., Texas (2011)


“Dr. Klein’s program works. It’s been six months since I contacted Dr. Klein. I had been sick for 1-1/2 years before I came across his website. I had been to many doctors without help. A GI had told me to be realistic, that there was no name for my condition and no cure and that I would have live with pain the rest of my life. I followed the diet in Self Healing Colitis & Crohn’s, along with some counseling, and I feel that my best days are ahead of me.”

-William K., Sacramento, California (2011)


“I was diagnosed with Crohn’s disease in April of 2011. I was immediately referred to gastroenterological care, but because I lacked medical insurance not a single gastroenterologist where I lived would take me on as a patient. This turned out to be a blessing in disguise.

I began reading books about my Crohn’s to self-treat as best I could. Typically, I came across three kinds of books on the topic. The first kind recommends getting on with standard modern medical treatments, which involve taking powerful dosages of antibiotics, immunosuppressants, and other drugs. They also recommend things like avoiding fibrous foods and other foods that might exacerbate the symptoms. The main person to seek help from here is a gastroenterologist, who is supposed to be the medical authority on intestinal diseases.

The second kind of book recommends alternative approaches to treating Crohn’s. They recommend different kinds of herbs, oils, supplements, probiotics and macrobiotic diets for people with Crohn’s to experiment with. Many of these books recommend seeing a naturopathic doctor.

The third approach I found was an integrative approach. What is really needed, it is claimed, is proper gastroenterological and naturopathic care, and whatever other care you might feel you need.  Human bodies are unique, they stated, and need to be experimented with, and one who has an intestinal disease cannot afford not to see medical professionals. Gastroenterologists and naturopathic doctors can work symbiotically to maximize proper treatments. One can take dosages of drugs that her gastroenterologist prescribes, and one can also take the herbs, oils, supplements, and probiotics that her naturopathic doctor recommends, etc.

I dabbled for a week or so with some recommendations that I could get from my local health food store, but these made my symptoms worsen. I did not want to go the modern medical route, and could not anyway due to my lack of medical insurance. Accordingly, the integrative approach seemed hopeless.

One night I went online to see if there were more books I could check out.  I found Dr. Klein’s book, Self-Healing  Colitis and Crohn’s. As I began reading it I had a feeling that Dr. Klein was speaking truth. There was something about the presentation, the arguments, the Natural Hygiene philosophy that made so much intuitive sense and, perhaps more importantly, made me trust Dr. Klein’s teaching. He had been through severe ulcerative colitis himself, he reversed his condition, and, inspiringly, went on to find true health. This was important for me. He did not, as I had read in so many testimonials in other books, keep his condition in check for a while only to experience future flare-ups or go through what seemed to be the usual cycles of colitis. He was able to reverse his condition indefinitely.  And, the results were immediate.

I followed Dr. Klein’s advice. Overnight, I became a low-fat, high carb (fruit!), raw vegan, following food combining principles and putting his teachings into practice. On the second day I was eating fruit without pain!  I hadn’t eaten without pain for months!

Over time, I began to internalize his teachings, and after a month or so I jo longer felt pain in my ileum and the inflammation seemed to have run its natural healing course.  I was able to eat more and more fruit and some tender vegetables. Six months later, as I write this, my health has never been better. I am still following Dr. Klein’s principles and am not looking back!  I have found true health.

I thank you so much Dr. Klein!  You truly helped me when I was in great need. My debt to you and your work is great indeed.”

“I would like to join the hundreds of people who have thanked you for helping me out with your great book, Self Healing Colitis & Crohns.  I had been diagnosed with light gastritis since 2006. Then, during the month of August of this year, I began experiencing an increasing bloating problem. It culminated in a bout of violent vomiting one night and a trip to the emergency room. The doctor, once he saw that I could keep down food, released me and told me to see a G.I. specialist. He wrote the diagnosis “colitis” on my release papers.

I was disappointed with that the G.I. doctor could not see me for four weeks. Suffering and in pain, I took a three-hour trip to San Luis, Rio Colorado, Mexico. The small-town doctor I saw was able to calm my symptoms and help me with some guidance. She put me on antibiotics, anti-diarrhea, lactobacillus acidophilus, and pain reliever pills. I went home thinking this regimen would work. I don’t believe it did.  Now, this is where you come in.

I was searching online as best as I could, being that I was on the john ever hour for three days! I was so exhausted during those days. After reading pieces of your advice from your www.colitis-crohns.com website, I dropped the pills and ate only banana, and peeled apples and pears. The bloody stools went away in less that two days! By the fourth day,I was eating solid food with no symptoms of colitis. This was in view of my family who was against a pure fruit diet.

During week two of the healing stage I had regained my strength. At the end of the week I had an appointment with my doctor in Mexico again to check my blood work and see how I was coming along. The colitis was gone!

I give thanks to God, foremost, and to you, Dr. David Klein for the insight and wisdom of your work. I am now symptom-free and feel great. I have no more morning stomach pains, the bloating is gone and my stomach doesn’t swell or get sour after eating.

I pray that I can recommend your words and wisdom to any who may come my way and to family, friends, and others. God bless you.”

“I am writing to let you know how much your diet has helped me heal from Crohn’s disease. I have been following your diet plan since April, 2011 and have had experienced nothing but improvement since then. When I decided to try your diet I was unable to attend university, was struggling to work half-day weeks and spent most of my time in bed. I suffered from painful digestion, stabbing intestinal pains, bloody stools, chronic diarrhoea, potassium deficiency, adrenal exhaustion, gastric reflux, chronic fatigue and chronic dizziness.

After trying all the usual harmful medical treatments, i.e. steroids, anti-inflammatories etc., with no success (in fact, they just made things worse) as well as naturopathic supplements and a high protein and fat diet, I have found your diet plan to be the only 100% successful and side-effect-free way to overcome Crohn’s disease. Moreover, by living more in accordance with the principles of Natural Hygiene I feel healthier and more vibrant than before I got sick!

Eating a diet consisting of fresh, organic fruit and vegetables has improved my mood and outlook on life. My skin has cleared up, my digestion is greatly improved (provided I combine foods properly), I scarcely need to use shampoo and have healthy, glowing hair, I have more energy and muscular endurance, clarity of mind and my weight has returned to normal (after being slightly underweight when I was sick).

The most profound change, however, is the empowering knowledge that I have healed myself naturally without any supplements, drugs or modalities. I now live according to the principles of the 80-10-10 diet and am working on improving my fitness and incorporating more sport into my lifestyle. I could not have had all this success without your guidance Dr. Dave, and I am eternally grateful for your work.”

-Francine Maas, Kensington, Australia (2011)


“I was diagnosed with ulcerative colitis when I was 20. I remember how crushed I felt when the doctor told me there’s no cure, that I need to be screened for cancer every year and that it would be likely that I would need surgery in the next 10 years. I tried several medications, but the side effects were so horrible that I decided I would just rather deal with the pain. There were so many days that I skipped eating just so I could avoid a bowel movement. It was disabling both physically and mentally.

At some point I was told that not eating animal products could ease the pain. This sparked my curiosity. I searched “vegan ulcerative colitis” on Google and came to Dr. David Klein’s website. I was very skeptical. It was contrary to everything the specialists told me. However, after one too many weeks of being in agony, I didn’t care anymore and was willing to try anything.

At the time I was eating the Standard American Diet including lots of meat and cheese, refined grains and processed food with not very much fresh produce. I ordered and followed Dr. Klein’s Self Healing Colitis & Crohn’s book and gradually incorporated healthful practices into my life and started feeling much better at a surprisingly fast rate.

After several weeks I was having normal, healthy bowel movements again. Eventually I became as fit as my former 16 year-old self. I felt better than I had in my entire life and am ever grateful.

Thank you so much, Dr. Klein!”

-Joseph P., Portland, Oregon (2011)


“For about eight years I had an unknown colon condition that included inflammation. I tried many kinds of colon cleanses, enemas, implants and colonics that helped a little, but did not clear the condition. Then I had a tooth infection. My dentist said I needed antibiotics, which I normally don’t take. My body’s reaction to that severely increased the colon condition.

I knew that I needed help and fast. I had the good fortune of hearing Dr. David Klein on a web teleconference speaking about Healing the Gut and speaking about his book, Self Healing Colitis and Crohn’s. I felt immediately guided to buy and read the book and contacted Dr. Klein. He guided me with the Natural Hygiene Vegan Healing Diet Plan.

I had been on a vegan mostly raw diet for 16 years. While reading Dr. Klein’s book and while on his program I realized that I had been eating too many nuts, cooked oils and improper food combinations. Through Dr. Klein’s guidance I also went off herbal laxatives. After 7 weeks on the Natural Hygiene Vegan Healing Diet Plan, the condition and symptoms were gone.”

-Mary S., California (2011)


“I have been following your book, Self Healing Colitis and Crohn’s to the T and after a week I had the first solid BM in 2 YEARS!!! It was hard and at first nearly impossible to stick with (I have two kids and a family to cook and prepare food for) but now it’s much easier because I’m feeling the results..It’s working!!! A miracle!! I’ve been teaching my kids about how the body can heal itself if given the right foods and  getting rid of the wrong ones. Thank you. I have money again (our coffers are dry after all the doctors and acupuncturist and therapists and..etc.!!) I want to call you and talk. I’d love to know how people deal with going out to meals, camping, traveling and such. Also, living at 9,000 ft elevation in Colorado (no local fruit) has been a big challenge!

Thank you for all that you’ve done for the world. You are an amazing man.”

-Renee E., Colorado (2011)


“I’m feeling great today and I was finally able to move my bowels.

Also, my “body-talk” appointment was great. Everything the practitioner said and did went along with your book and my self-healing body’s wisdom.

Everything is wonderful right now. I swear, your book belongs on the Wikipedia page for IBD.

Nothing but love and praises for you!”

-Dylan E., Tahoe City, California (2011)


“I can not say enough good things about Self Healing Colitis & Crohn’s. I literally want to shout about it from my roof top! It changed my and my family’s lives forever! I was diagnosed with UC in August of 2000 and took the standard medical route of steroids and Asacol. I got ‘better’ in time and spent the next nine years in ‘remission.’ But that did not last.

After the birth of my second child in May of 2009 I had a major flare-up that did not respond to the medication. I was running to the bathroom eight to ten times a day with cramps so bad that I felt like I would pass out. I lost 40 pounds in a little over a week. My family had to come stay with me to take care of me and my children. My doctor started suggesting surgery and wanted to put me on Remicade, neither of which I saw as options. I was in a self-imposed hell, angry and drowning in self-pity.

By the grace of God I made the decision to buy Self Healing Colitis & Crohn’s. The vegan diet aspect totally turned me off at first; however, being on such a limited diet anyway, it wasn’t far to go to be ‘vegan.’ Upon reading this book and following the guidelines of self-healing my life started to change. When I say ‘guidelines of self-healing’ I don’t mean simply diet. I mean changing my attitude toward my situation and myself. There is more to this book than becoming a vegan of following a strict diet—the importance of the other aspects of health cannot be underestimated.

Within the first week of applying the self healing principles I went from not having the strength to walk to my mailbox to taking mile-long walks around my neighborhood! The symptoms of cramping, gas, mucous and constipation started improving within that same week. Within four weeks I was symptom free!

I followed the diet to a “t” for five weeks then slowly started trying new foods. I found I could tolerate many things—which I was ecstatic about—but I soon realized that I didn’t want my SAD (Standard American Diet) diet back. The foods I used to eat, especially meat, tasted terrible. My body and palate had completely changed! Of course this didn’t happen overnight and the process was miserable at first. I obsessed over the foods I wasn’t ‘allowed.’ But now I don’t even think about them. I have occasional treats, but find it very easy and wonderfully simple to continue the healthy diet.

It is also remarkable to compare the vast difference in how I felt during the nine years of ‘remission’ and how great I feel now. I thought I was totally normal, but now I realize I wasn’t. Even though I felt fine, my digestion wasn’t up to par—I just accepted it, like so many people do.

Dr. Klein does a superb job of explaining the simply beautiful self-healing process that will take place if we allow it. I have suggested this book to friends and family who don’t have digestive problems, but suffer with other health problems. I know that the guidance and advice in this book will have profoundly positive effects on anyone suffering from minor to major health problems. I am forever thankful for this book and for Dr. Klein writing it.”

-Allison S., Oregon (2010)


“I was diagnosed with UC and bought Self Healing Colitis & Crohn’s at end of May, 2010. I had eaten an unhealthy vegetarian diet up until that time. I read your book three times and after strictly applying everything you advise I am now healed. Not all of my energy is back yet, but I’m out of bed and preparing the healthy food for both my husband and myself. I threw away the horrible medicine I was handed, lost 20 pounds of morbid fat and feel wonderful. Thank you.”

-Paulette W. Auburn, California (2010)


“It’s amazing Dave, truly amazing. I am putting on weight! The body truly is self-healing! All this time I’ve been doubting and not too sure, but what I have learned and achieved is nothing short of amazing. I still have my green juice in the morning and can’t imagine starting the day with tea or coffee, the idea is so repulsive. I love salads and vegetables and I am not interested in cooked food. It’s strange how after you heal you don’t have cravings, but throughout the healing phase cooked food was all I craved.

I have enjoyed getting to know you and hope we can stay in touch. Big kisses and big hugs to you!”

-Emma Kaid, London, England (2010)
