If you’ve been eating “perfectly,” taking your probiotics, and still feel bloated, backed up, or uncomfortable, you might be dealing with Methane SIBO, also known as Intestinal Methanogen Overgrowth (IMO), a commonly missed diagnosis that’s keeping your gut stuck in slow motion.

In this episode, Alyssa Simpson breaks down:

  • What Methane SIBO actually is and how it’s different from hydrogen SIBO
  • Why it causes bloating, constipation, and sluggish digestion
  • How stress, surgeries, and medications set the stage for overgrowth
  • Why standard tests often miss methane overgrowth
  • What testing options and diet changes can help you finally move forward

You’ll walk away understanding the “why” behind your symptoms and the first steps to start healing.
