SIBO (Small Intestinal Bacterial Overgrowth)

SIBO is one of the most under-recognized causes of bloating, reflux, irregular bowels, and food sensitivities. Dr. Seubert is affiliated with the Naturopathic Gastroenterological Association (GastroANP) and routinely identifies SIBO in patients whose previous workups dismissed it.

Clinical Approach
  • ◆Breath testing interpretation (hydrogen, methane, hydrogen sulfide)
  • ◆Antimicrobial protocols — botanical or pharmaceutical, individualized
  • ◆Motility support to prevent relapse
  • ◆Dietary phasing during and after treatment (not lifelong restriction)
  • ◆Addressing root causes: ileocecal valve, post-infectious IBS, stress
Common Signs & Symptoms
  • ◆Bloating that gets worse through the day
  • ◆Reflux or GERD that doesn't respond fully to PPIs
  • ◆Alternating constipation and diarrhea
  • ◆Food sensitivities expanding over time
  • ◆Skin, joint, or mood symptoms tied to meals
Questions

About SIBO (Small Intestinal Bacterial Overgrowth)

Is SIBO the same as IBS?+
