You've Googled "SIBO treatment" so many times your phone autocompletes it.
SIBO — Small Intestinal Bacterial Overgrowth
You've tried the antibiotic. Maybe you felt a little better. Maybe you felt worse. Maybe you felt absolutely nothing at all and wondered if the pharmacy gave you sugar pills.
And now you're sitting there thinking:
Do I treat again?
Switch to herbs?
Try elemental diet?
Start a prokinetic?
Change the diet?
All of the above?
None of the above?
Nobody handed you a roadmap.
You got a diagnosis (if you were lucky enough to get one that was actually read correctly... but that's my story and I'll get to it). And then you were pretty much on your own.
I know. Because I was you.
This masterclass is your next step on the roadmap we will build for you together.
Small Intestinal Bacterial Overgrowth (SIBO) is a condition where certain organisms overgrow in the intestines, interfering with digestion and nutrient absorption, and causing symptoms like altered gut motility and bloating. SIBO is now recognized as a leading root cause behind IBS, chronic bloating, food sensitivities, reflux, and stubborn digestive symptoms that keep coming back.
Stop spending months, sometimes years, bouncing between protocols you found searching late at night - Reddit, Google, ChatGPT.
Or supplements your friend recommended, and diet advice that contradicts itself depending on which blog they read last.
We watched this happen to hundreds of people in our community. And honestly? I lived it myself. Nobody told me to retest. Nobody told me to look at my gas levels and do the math. Nobody told me that not feeling better didn't mean the treatment failed, it meant we weren't done yet.
That is exactly why this masterclass exists.
Not a summary.
Not a "top 5 tips for SIBO."
Not a 10-minute video where someone waves their hands and says "work with a practitioner."
I'm talking about the real, detailed, protocol-level information that Dr. Allison Siebecker used with her own patients.
The same Dr. Siebecker who has been specializing in SIBO longer than almost anyone on the planet.
In this masterclass, Dr. Siebecker walks you through everything.
The treatment options.
The specific doses.
The protocols for hydrogen, methane, and hydrogen sulfide.
The prevention strategy that keeps you from relapsing.
The schedule that actually makes a difference in outcomes.
She even shares the slides as detailed notes you can take home, because that's how she likes to teach.
Everything is right there in black and white so you can reference it later, share it with your doctor, and actually have an informed conversation about your own case.
And yes, you also get all the materials, so you can watch it again and again.
Everything you need to know about treating your SIBO and preventing relapse. Dr. Siebecker is detailing all the types of SIBO, including Methane and Hydrogen Sulfide specific protocols. The six main prokinetics for SIBO prevention. The same methods that have helped thousands of people finally get relief and hold on.
"One round of treatment is often not enough, and that is the standard, not a failure. When you understand the process and the math behind your gas levels, you start seeing a clear path forward."
— Dr. Allison Siebecker

“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.”

“This is not beginner content dressed up with a fancy name. This is the clinical-level information that practitioners fly across the country to learn at medical conferences. And Dr. Siebecker presents it in a way that patients can actually understand and use.”

Together, we created these resources to give you the guidance and support we wish we had when we started our own healing journeys. We’ve both been where you are now, and we know exactly how overwhelming it can feel. But we also know there’s a way forward — a clear path to healing that we’re excited to share with you.

Dr. Siebecker is the 2021 GastroANP Lifetime Achievement award winner (from her peers) and has treated SIBO exclusively for 15 years. She is in an instructor of advanced gastroenterology and NUNM and co-created the SIBO treatment algorithm used by practitioners worldwide. She's not teaching theory. She's teaching what actually works—the interpretation methods she uses with real patients who finally got better and practitioners around the world.

Shivan Sarna, founder of SIBO SOS® and author of Healing SIBO. After a lifetime of digestive problems, she was diagnosed with SIBO (Small Intestine Bacterial Overgrowth) in 2015. Shivan was so excited to finally have a name for the symptoms that made me miserable – but she was quickly very frustrated by how hard it was to get access to reliable SIBO information, or even an appointment with a doctor who had experience treating SIBO. She set out to get answers about SIBO for herself – but along the way, she met thousands of people who had the same challenges.
With this Masterclass, you'll be on your way to less pain, suffering, isolation, frustration, and embarrassment. Get your life back! It is possible, with the right information.
