What people are saying ...

“The content Shivan and her team creates is leaps and bounds above anything else you will find online. As a patient I feel so empowered to collaborate with my providers because I am actually able to understand what is going on in my body thanks to hours and hours I have spent watching, reading, and listening to these classes and videos. These masterclasses dive deep into the current understandings of SIBO, gut issues, and other comorbidities. I literally can not imagine where I would be without her and all of this content.” - Ann P

Shivan Sarna After a lifetime of digestive problems, I was diagnosed with Small Intestine Bacterial Overgrowth in 2015. I was so excited to finally have a name for the symptoms that made me miserable – but I quickly realized accurate, up-to-date information on this condition wasn’t widely available! My mission was to change that! I created the SIBO SOS® Masterclass Summit to give you access to the expert information you need to understand, treat, and beat SIBO! .Learn directly from the experts at your pace – all from the comfort of your own home! . I’m alongside you for support, guidance, and a shoulder to lean on. I’ve been where you are today, and it would be an honor to help guide you forward. Let’s kick SIBO’s butt together!
