Beginning as a child, Melanie Keller suffered from digestive issues (mainly constipation) that continued well into adulthood.

It wasn’t until she was earning her naturopathic medicine degree that she finally learned the cause – SIBO, or small intestinal bacterial overgrowth. Or rather for her, an overgrowth of methanogens were causing her constipation.

Melanie treated her overgrowth – only to see it return again and again. Eventually, she found the real root cause of her digestive problems and ways to treat it and keep it from coming back.

Lasting Treatment for Methanogen Overgrowth

In the latest episode of Rebuilding My Health Radio, I talk with Dr. Melanie Keller.

Dr. Melanie earned her doctor of naturopathic medicine degree from the National University of Natural Medicine (NUNM) in Portland, Oregon. Her education included an extended internship and post-graduate training with Steven Sandberg-Lewis as well as post-graduate training with Allison Siebecker. She went on to become a founding physician in the development of the SIBO Center and SIBO Symposium at National University of Natural Medicine.

Once in Southern California, she spent time with leading SIBO physician, Dr. Mark Pimentel, MD, and his team at Cedars-Sinai’s GI Motility Program and the Pimentel Laboratory.

While in naturopathic school, Dr. Melanie discovered the cause of her longtime digestive problems: SIBO. She eventually treated it successfully, but it took multiple tries.

Now, she shares this knowledge with her patients, for whom she develops highly individualized treatments.

In this episode, Melanie primarily shares how she was able to treat methanogen overgrowth without antibiotics.

In my conversation with Melanie, you’ll hear…

  • How she discovered her own SIBO
  • About the different types of SIBO
  • Why methane overgrowth is technically not small intestinal bacterial overgrowth
  • How too-low or too-high stomach acid contributes to SIBO or methanogens
  • The type of testing required to assess stomach acid levels
  • The steps she took to treat SIBO without antibiotics
  • How addressing her stomach acid levels made all the difference for her
  • The role of diet and why long-term restrictive diets are not recommended
  • How she prevents SIBO relapses
