The Digestion Coach™ Est. 1989

LIFE CHANGING! That's how I describe Dr. Ettinger's treatment and cure for H. pylori and SIBO, which have caused me misery over many years. I've seen multiple doctors and gastroenterologists over the years who only put me on multiple rounds of antibiotics and PPIs for the H. pylori that wreaked havoc with my digestive system and overall well-being. I couldn't even complete the weeks of harsh antibiotic treatment because it made me so sick, leaving the H. pylori and all the other digestive problems unresolved. They had nothing else to offer that could rid me of the debilitating digestive problems that were taking over my life (except to tell me to follow a low-FODMAP diet).

After much research, I found Dr. Ettinger, who was confident that my issues could be treated successfully. He explained the relationship between SIBO and the H. pylori infection. He prescribed a targeted treatment of supplements that not only addressed and resolved my complex digestive problems but also had no nasty side effects.

I can't thank Dr. Ettinger enough for giving me back my health so I can enjoy my life again. I'm eating normally, I'm back to working out, and I'm not letting digestion problems take over my life. I will always consult Dr. Ettinger for future health issues--he's truly amazing!

I was referred to Dr. Ettinger by a friend after my daughter struggled with Ulcerative Colitis.

At 13, she had lost 25% of her body weight, weighed only 69 pounds, and was homebound, homeschooled, and had a very poor quality of life due to the illness. Her traditional GI was pushing for Immunosuppressive drugs, but after reading about all the risks and side effects, I couldn't do it unless it was a last resort.

After working with Dr. Ettinger and his knowledge about the body, what causes certain conditions, and how to heal the body naturally with diet and nutritional supplements, she is now back in school, playing sports, actively involved at church, and back to a healthy weight and living her life again.

Dr. Ettinger is caring and authentic. He truly cares about his patients and is dedicated to helping them get well. He has been very flexible, and I have no problems getting appointments when I need them.

I found Dr Ettinger through a family member who recommended him to me. I have been a patient of his for almost 3 years and he is AMAZING.

I have back issues and used to have gallbladder attacks on a monthly basis. Since he is a holistic doctor as well, and I did not want surgery to remove the gallstones, I quickly went to him. I have not had one attack since. Not to mention, my back feels like new.

He is very passionate about his work and loves helping people feel their best!

I was helped by Dr. Ettinger for H-Pylori, and within two to three weeks, it was gone. The protocol included several supplements, which was much better than taking the high doses of antibiotics that are normally prescribed for this bacteria.

He is knowledgeable in all aspects of holistic health and is genuinely interested in helping his patients.

Dr. Ettinger has been treating my daughter for over 3 months now for inflammatory bowel disease.

Since May 2011, she has been through many hospitalizations, multiple surgeries, and pharmacological treatment - none of which have helped her. Dr. Ettinger has a brilliant mind and is very knowledgeable in the areas of chiropractic, chronic diseases, nutrition, diet, and holistic remedies. As soon as we met him, we knew we were in good hands. He has a BIG HEART! He is genuine, sincere, and caring towards my daughter and me. We just wish we had found him sooner. I am very grateful to him for his help.

On a side note, he is helping me with my chronic insomnia that has plagued me for 18 years. We look forward to our appointments with him and leave feeling positive and happy every time. I cannot thank him enough for everything he has done and continues to do in our journey for wellness.

I had a Heliobacter pylori (H. Pylori) infection. It produced wind in the stomach and bowel and great pressure, which produced severe pain referred to the chest and so was initially thought to be heart problems.

Eventually, it was treated successfully with a couple of antibiotics. They killed all the bacteria in the gut, of course, and although the H. pylori stopped giving me trouble, I began to get every infection that appeared in my grandson's school. He did not have to get the infection - he just passed it on. I got everything until I began to take probiotic supplements.

Then, after a few years, the symptoms of H. pylori reappeared. Not wishing to use antibiotics again, I consulted Marcus Ettinger and took what he prescribed. The infection was dealt with, and it has not reoccurred this time.

I have been a patient of Dr. Ettinger's for over a year now, and he has been instrumental in helping me regain my health.

When Kaiser dropped the ball, he picked it up and ran with it. He analyzed all of my past labs and discovered issues that were contributing to my chronic pain and inflammation. He created a supplement plan that has really helped me feel well again.

He cured my SIBO after prior treatments had failed. He is also an amazing chiropractor. My pain level was an 8, and it's down to a 1-2. My 85-year-old mother sees Dr. Ettinger as well and loves him!

His protocols have improved her daily health tremendously.

I first met Dr Ettinger a year ago when the practitioner I usually see was not available. This was meant to be because I have since become the recipient of an excellent standard of holistic care.

The sharp stomach pains I had been experiencing for a week were 90% better by that evening, and I was able to go to a concert.

Also, on later visits, he helped me identify and treat the bacteria causing my sinus infections.

I appreciate how present and sincere he is and how I did not feel rushed, as I often do with other holistic chiropractors. Also, he is happy to explain the mechanisms behind what he is doing and is never condescending, always willing to teach and share as he goes. Dr. E's background in biochemistry and his decades of experience as a medical detective, combined with his patience and empathy, make him a first-rate, true holistic care provider.

I saw Dr. Ettinger about 5 times over a period of 6 months and he helped me to get rid of a nasty bacteria called H-Pylori. I was fighting my stomach problems for about 4 years before I found Dr. Ettinger doing online research.

The first contact with Dr. E. was over the phone. He called me right back after I left him a message. That's how everything started. I live in LA; his office is in Orange. To stay out of heavy traffic, I would leave Saturday morning early to go to my appointments. Dr. Ettinger has always been kind and patient, even when I was late.

After all those years, I can finally eat and drink whatever I like. I am so happy; I have my life back. I highly recommend Dr. Ettinger, his knowledge is amazing and he really loves what he is doing.

He has given me my life back. I will always be thankful for it.

Thank you, Dr. Ettinger.

(I have consulted different health professionals, did research for hours, and spent tons of money to cure myself. H-pylori is a nasty bacteria, and many people still have not been cured after many rounds of antibiotics.)

I first went to see Dr Ettinger in April of this year. I was having a terrible Ulcerative Colitis flare, which ended up putting me in the hospital for a week.

With Dr. Ettinger's wisdom and experience, he was able to help guide me so that I could get off of my medications and heal in a more holistic way.

I was truly at one of my lowest points. He was gentle, patient, compassionate, and very understanding. He gave me hope so that I could believe that I would heal.

With some trial and error, we found what works, and I am almost in complete remission and have gained back the 20 pounds I lost during my flare.

Dr. Ettinger is the real deal! A true holistic healer with the science to back up his approach. He is very well-read and researched. I trust his wisdom, and I am so thankful to have him as part of my healing team!

I had struggled with compounded digestive & psychological issues (IBD) for the better part of 8 years. I'd seen a wide array of doctors, spent way too much money on countless supplements, and tirelessly researched my condition to no avail. I genuinely thought I was going to spend the rest of my life (I'm only 24) chasing my health, never getting better, constantly wishing for a solution.

When I came across Dr. Ettinger's articles, I was impressed by the level of clarity, depth of research, and comprehensiveness of solutions. On a whim, I gave him a call. It was the best decision I've ever made. After getting my test results back and following Dr. Ettinger's (much simpler and much cheaper than what I had previously been doing) protocol, I was a different person. For the first time in my life, I consistently wake up every day feeling well. I'm so thankful I made the change and so thankful people like Dr. Ettinger exist. If you have a chronic health issue, please don't ever give up.

Your health is within reach, and people like Dr. Ettinger can help you find it.

In summary, Dr. Ettinger is an incredible functional medicine practitioner and overall human being. He was my first ray of hope during an extremely difficult time with my health, and I will ALWAYS be grateful for his expertise and kindness.

About a year ago, my health started to deteriorate. It was a horrible and complicated downward spiral of gut health issues that started with stomach acid refluxing up to my throat, followed by the inability to eat without throwing up or having severe upper abdominal pain (pain so bad that it often felt like I couldn't breathe). I had dropped from 102 lbs to 87 lbs over the course of 2-3 weeks

The issues were so severe that I had developed a deep fear of eating, and I was constantly extremely exhausted from both the anxiety I'd developed on top of the lack of proper nutrition.

Desperate for help, I started researching how other people had solved their gut issues, and somehow, I'd found Dr. Ettinger online. I called for a consultation, and Dr. Ettinger was the FIRST person to actually listen to me and give me hope that I could go back to eating and living normally. I'm pretty sure I was crying over the phone, and he was still very patient with ensuring I felt heard.

During my first visit to Dr. Ettinger, he provided me with the supplements needed to help my body heal. At that point, I'd never turned to supplements for my health, and he had given me quite a lot. I admitted to him that I was afraid (keep in mind the anxiety), but he was very kind to talk me through things.

The changes in my ability to eat were pretty much immediate. In the next few days, I was able to eat without throwing up or developing abdominal pain, which was incredible. While I was required to slowly re-introduce food and limit what I ate at first, finishing the supplement protocol itself took 3-4 weeks. My situation was extremely complicated, and while I did end up seeing other health practitioners (a therapist, nutrition coach, PT, and acupuncturist), Dr. Ettinger gave me the crucial steps for my body to begin to heal.

If you are experiencing gut health issues like I was, PLEASE reach out to Dr. Ettinger (don't worsen your health by trying to Google / self-diagnose like I had done). He's a wonderful person, and I've recommended multiple colleagues to him already.

I often think about the discipline Dr. Marcus Ettinger instilled in me in the two meetings we had a few months back, and I'm ever grateful that I was introduced to him! I eat lunch daily, whereas before, I would eat maybe twice a day or one whole meal that would go on for hours because I was just too damn hungry!

I cannot tell you all how undisciplined I was with my eating, so much so that my body rebelled with headaches -borderline migraines- every single day. I would wake up with them and go to sleep with the same.

This became my primary reason for my visit with Dr. Ettinger. I also had gallbladder surgery a while back, which was another reason for my visit with him, and honestly, guys, he kinda saved my life! Of course, I was hesitant to go in because I already knew my habits were quite bad, embarrassing even, but he didn't make me feel ashamed of how I treated my body and explained very clearly why my body acted the way it did.

I was asked to do some lab work before going in to see him for the first time, and he calmly explained how bad my bloodwork was - not to scare me BUT to inform me that ALL this can be changed with just a drastic change of lifestyle and diet, which I gladly and humbly obliged.

He first ensured I was ready to take the next step as he doesn't believe in traditional medicine and asked if I was willing to undergo a drastic lifestyle change; you MUST be prepared to WANT a change. He provided me with some vitamins and some Super Enzymes to rebuild my gut and guided me to a better and cleaner diet; this change made me feel 133% better, the best I've felt in all my life.

If you're tired of doctors stuffing you down with experimental medicine, check out Dr. Ettinger - you won't be disappointed by this investment in yourself.

This review is about four years overdue, but I cannot express enough gratitude for Dr Ettinger. I originally had been seen in 2020 for SIBO, and the treatment was life-changing. Whether you are coming to him with unanswered health concerns or a chiropractic adjustment, you will be more than happy that you did!

He is a wonderful human who takes his time with every single person to ensure quality care and to spread knowledge to give patients the tools to help themselves live happier & healthier lives. You will always leave his office feeling better in more ways than one. He is a true healer.

Thank you, Dr. Ettinger, for everything over all the years! I can never thank you enough.

Dr. Ettinger, I wanted to let you know that I'm feeling better than I have felt in years! I was impatient at first, as I'm sure you know, haha, but as the weeks went on since we last spoke, every day I've been seeing improvement in my digestion. It's to the point now where I'm able to eat much more variety than I used to without a trace of pain, gas, loose stools, or bloating. It's so phenomenal!!!!

I have been taking the diet slowly. I'm actually eating more of a plant-based diet now, with all organic vegetables, healthy meats, ancient grains (like you mentioned), and fermented foods. I also noticed that I no longer see any undigested food in my stools, nor are they loose like before, which seems to be getting better by the day!

In addition to that, I'm weight lifting normally again and I'm gaining weight by the week!! I'm also getting consistent spinal adjustments by a chiropractor and that has seemed to further help my digestion and stress.

I wanted to tell you how much you have helped and made a difference in my life. You were always there when I felt I needed to talk to you about my digestive issues and you’ve always put so much effort in helping me get better. I’m forever grateful for that! Thank you from the bottom of my heart!

Sincerely, Mary

Dr. Ettinger is someone I recommend to anyone and everyone! In January, I became very sick while traveling. My symptoms consisted of fatigue, diarrhea, a metallic body odor, stomach pain, blood in my stool and urine, headache, nausea, shortness of breath, and consistent yeast infections. Right when I got back in the States, I went to multiple doctors to see what was going on.

Doctors kept guessing and put me on many rounds of antibiotics, which messed up my stomach and did not help any of my symptoms. I had stool tests taken, blood work done and much more. No one could give me answers for months, and they kept pushing me to the side, saying I would be fine. I knew I was not fine and had to be my own advocate.

I was out of work and in bed, this whole time and just wanted to feel healthy again. Finally my friend recommended Dr. Ettinger. The first phone call I had with him, he made me feel so assured that we would figure this out. I thought, "Finally! Someone who cares and is trying to understand me!" One zoom call was all it took for him to give me a protocol.

3 days after taking the vitamins/supplements he recommended, I could finally get out of bed and start healing. 2 weeks into taking the vitamins, I was 100%! I am doing so well, and I could not be happier! I have finally found someone I trust with my health. He is extremely knowledgeable and cares about his patients. I don't know what would have happened if I never found Dr. Ettinger. I am so thankful for him and blessed that he came into my life during that time.

If you are even thinking about needing to see someone about a health problem or knows someone that needs to, do yourself a favor and see Dr. Ettinger! I wish I would have seen him right when my friend told me to instead of waiting a month after. He is incredible (and that word doesn't even explain it). Thank you Dr. Ettinger!!!

This is my second review after 2 years of completing treatment with Dr Ettinger.

It has been almost two years since I finished my treatment under your guidance. I can say that I have fully recovered from Pan gastritis ( H Pylori), acid reflux, and IBS by the end of 2022.

I will turn 40 next year in March. I started to train MMA a few months ago. I know that I am too old to practice this sport. There is loss of agility as we age, I can't perform like fellow trainees who are in their early 20's. I am the oldest in my gym. There was a question that came into my mind, am I too old now, should I start training? Is it too late now? As the window has passed now, I am almost 40 years old now. Will I be able to put my body to all that strain and pain for training MMA?

Then I thought it is never too late, yes it was very hard in the beginning. I had to accept where I am in my life and how my body is going to react to what will be thrown at me in the gym.

I stopped comparing myself to other trainees who are 15-16 years younger than me. I started focusing on my journey and training. I'm focusing on improving myself and what this training is bringing in to improve myself. I am learning Boxing, Muay Thai and Jiu jitsu.

I am now ok to feel and experience pain and soreness and learn how to push past it.. The growth that I am now experiencing is beyond physical. The growth I am talking about is mental and emotional. This is better than anything else. I took it slower and had patience while training. I was happy with every inch of progression in training. I just kept going.

Getting started was not enough, I kept discipline. and discipline kept me going. Waking up at 4 am in morning, after bath doing meditation and then hitting gym at 5:15 am in morning. Then in the office at 9 am. Back home at 6 PM and then giving time to my son and wife. Going to bed by 10.

I have fallen in love with this journey. I am taking care of my body and not doing things that made me unhealthy 5 years ago. In fact received many injuries in the first few weeks, but have overcome all that. I have become more confident mentally to face any situation in life. I have become more open in life.Now in fact I feel stronger, lighter and faster than I was in my early 30's.

I have really fallen in love with new me.

Thank you sir for helping me cure from that chronic illness, you helped me from thousands of miles away from another corner of this planet when I had lost all hope of recovering. There is a saying in Hindi my native language - आग ज़ुबान पे रख दे फिर चोट के होठ भी गाएँगे। घाव गुनगुनाएंगे फिर दर्द गीत बन जाएंगे। ( Put fire on your tongue then even hurt lips will sing, wounds will hum and then pain will become a song)

I thank God for this new life. God bless you Sir.

My husband and I have been seeing Dr. Ettinger for a few months, and I must say he is a miracle worker. My husband has been suffering from H. pylori, and he had a severe case. For many, many years, he has been dealing with terrible symptoms such as abdominal pain, anxiety, digestive issues (having to eat every 3 hours due to the chronic acid), ulcers, etc. It held him back from living his life to the fullest, and he has improved tremendously!

We have seen several doctors both holistic and medical physicians, but nobody has been able to help him until we have been treated by Dr. Ettinger. My husband is finally living the life he has always wanted and is back to health, thanks to this doctor. As for myself, I have been dealing with a severe case of Postural orthostatic tachycardia syndrome (POTS). We have two kids, and for years, it has been incredibly hard to function. I would pass out constantly and daily feel like I could not get out of bed. I would experience fatigue, low BP, chest pains, tachycardia, nausea, headaches, and the list goes on. Again, we have seen so many docs, even a specialist for POTS, and nobody was able to figure out any solutions/cure.

Yet again Dr. Ettinger has surprised my husband and I on how he was able to restore my health with his treatment plan. Because of him, I can be fully present and live a happy and healthy life again. Doc saved my husband's and my life, and we are forever grateful to him. We are finally able to enjoy life with our little family!

For anyone who is truly looking for help, we absolutely recommend Dr. Ettinger--thank you, doc, for giving us our lives back.

Dr. Ettinger, Although under the care of a great local eastern Tennessee functional medical doctor now, I want to thank you for the thorough lab testing and analysis and Telehealth consultations, but especially for initiating a lifestyle and protocol that has improved my quality of life and my overall health. Since implementing your protocol and eliminating seed oils, nuts, sugar, caffeine, and dairy, and improving my gut health by creating an inhospitable environment to combat bacterial imbalances, and increasing my cholesterol by consuming red meat, eggs, and coconut-based oils, my cholesterol and testosterone levels have increased. As a result, my prostate is much improved.

There is a lot of data, studies, and podcasts now available that support your protocols, and therefore, what was once fringe is becoming more widely known. Like many, I thought cholesterol was the bad guy. It is truly tragic how big pharmaceutical companies have falsely impacted the public’s impression and practices.

Words cannot express my appreciation for you and what you have done for me. I continue to refer others to you and hope your guidance becomes more common as I am living proof you are on the right track!

God bless you and your family.
