Patient’s Testimonials

"Life-Changing Relief After Years of Suffering – Grateful for Dr. Rajsree’s SIBO Treatment I bought the full SIBO treatment after being diagnosed and struggling with symptoms for over two and a half years—constant pain, severe bloating, and watery diarrhea. I had seen multiple doctors, but none took the time to truly investigate what I was going through. Out of frustration, I started exploring natural treatments and came across Dr. Rajsree’s videos on YouTube. At first, I was skeptical due to past disappointments, but I had never tried a natural approach before. I followed her advice exactly, and within just two weeks, my bloating and pain were completely gone. For the first time in years, I could sleep through the night pain-free. The biggest surprise was that my diarrhea stopped entirely. I’m so grateful—this has truly changed my life."

"I could write a book about what a great doctor you are. Your philosophy is not only aligned with the best science but practical real world anecdotes. Watching your channel grow I’ve shared your videos which have resolved so many of my friends and families ailments. It took a year for my girlfriend to watch your videos but 4 weeks ago she has resolved her acne which was making her very insecure and depressed. Following your gut routine was the cure. After she spent $1000s on dermatologists with no results she finally followed your routine and 3 weeks later her skin is better. Your advice is gold. A real legend."
Jonathan Moynihan
"Extremely helpful! I watched her SIBO treatment video on YouTube and followed the protocol and purchased the supplements on her website. Amazing results!!! So blessed! Thank you"
Jesse Amelunke
"I started coming to Dr. Rajsree In 2019 and I cannot even put words how thankful I am that I found her! I had Sibo with stomach problems. I have followed Dr. Rajsree protocol and my stomach feels wonderful! Dr.Rajsree has guided me in taking control of my own health encouraging healthy eating and exercise! Dr Rajsree is on top of continued healthy living ... she's up to date and is an encourager, so clear in her advice and easy to talk to and understand and she listens! I love her videos on YouTube! I've watched and rewatched them and I feel better than I have felt most of my life! I’m 66 years old and I feel like I'm in my 20,s I cannot actually even put into words how thankful I am for my Dr."

"I am very grateful to have found Dr Rajsree. I was dealing with gut issues for a while and even with multiple visits over the years to a gastroenterologist only relieved my symptoms temporarily. It has been 5 months i started Dr Rajsree's treatment and so far it has been great. And i hope it stays that way. She is also very polite and easy to talk to. Again very thankful to have found a Dr who has deep understanding of underlying issues. "

"I was suffering from bloating, stomach pains, and generally not feeling well. After being tested by my functional medicine doctor he felt the issue was most likely SIBO. He directed me to Dr. Nambudripad's website with her SIBO protocol videos. I followed her protocol, using her supplements, for the 4 week period and my SIBO was gone. I felt well again, and resumed, over time, a normal diet. I continue taking Motility and probiotic supplements because they help me stay well. Thanks Dr. Nambudripad! "
Solved SIBO.
"It was Christmas Eve and I was stuck in the bathroom! I had taken the second round of the popular antibiotics for SIBO/IBS, and my gut was too weak to tolerate them. At my lowest point I turned the TV on, and on YOUTUBE were videos of Dr. Rajsree talking about the gut and SIBO/IBS. She was describing all of my symptoms! January 10, I met with Dr. Rajsree in person. She gave me a plan with diet, natural medicine, and herbal medicinals instead of the antibiotics. It really worked! I am whole! Dr. Rajsree laughs when I say, "You saved my gut; you saved my life!"
Rocio George
"After seeing two gastroenterologists who couldn't help me , I found Dr. Rajsree's videos on YouTube. I came to see her and she was the first person to diagnose and treat me for SIBO. Her treatment worked wonders and my bloating and constipation have resolved. I'm so happy to be be able to eat food without pain! She truly changed my life and I am forever grateful."
Adrian Brungard

She's just awesome.. make an appointment and go see her and her staff.. super people!!!"
Lisa Gillis
"Dr. Rajsree is such a breath of fresh air in the medical industry. I went to 4 different interests before finally finding her. Instead of trying to medicate my symptoms, she actually listened and help me get to the root cause, which none of the other doctors did. I am a work in progress but feel so much better. Highly recommend!"

"Dr. Rajsree is an amazing doctor. I love her approach of healing naturally through food and supplements before turning to medications and quick fixes. I wish all doctors would take this approach! She is a great listener and patiently answers all my questions. I love how she keeps digging and working to get to the root of the problem. She also has so much information on her Facebook and YouTube page."
