Small Intestine Bacterial Overgrowth (SIBO)

1_SIBODo you have clients with IBS, gas, bloating, diarrhea, or constipation? Have you had stool tests come back negative for pathogens, yet you know there is some larger issue going on in your client’s GI tract? It’s possible your client might have SIBO (Small Intestine Bacterial Overgrowth). With SIBO, normal bacteria in the large intestine have migrated up to the small intestine, where they don’t belong, causing a multitude of symptoms.

In this training, you will learn what SIBO is, why it occurs, which test is the best for detecting it, how to interpret a SIBO breath test report, the three types of SIBO treatments, natural herbal protocols for addressing SIBO, steps to take to prevent recurrence, and more. Listen to traditional naturopath and functional nutrition consultant Lisa Pomeroy share her knowledge and experience about SIBO in this 5-part in-depth series. Lisa is known for her comprehensive detailed training style, ability to make complex subjects easy-to-understand, and actionable recommendations. 

** Please note: These advanced courses are open to the public and you do NOT have to be a graduate of the FDN Certification Course in order to take these lessons!

“I thought the course was fantastic! I’m really glad I decided to purchase this SIBO module.  There was information in this course that wasn’t available in other SIBO courses I’ve taken. In particular, probably my favorite part, was the practitioner reference guide for SIBO protocols. Just having a list of different options for protocols (not just a one-size-fits-all protocol) is tremendously helpful. That protocol list is incredibly up-to-date with all the recent research, which is great. I’m very much looking forward to doing other FDN Advanced modules after this one.”
