Why IBS is not a real diagnosis with Dr. Monica Jauregui

Functional medicine offers a smarter way to address digestive issues. In this episode, Dr. Monica Jauregui explains why IBS is a “non-diagnosis,” how SIBO and leaky gut drive systemic inflammation, and what steps you can take to heal from the root cause.

In this episode of the Hormone Heroines Podcast, Dr. Monica Jauregui, an MD practicing functional medicine, shares her insights on why conventional approaches to digestive disorders like IBS often fail. Trained in traditional medicine but personally frustrated by its limits, Dr. Jauregui transitioned to functional medicine to better help patients address the root cause of illness rather than just masking symptoms.

She explains that IBS is a non-diagnosis — a term that simply means “we don’t know why your intestines are irritable.” Underneath the label, she commonly sees conditions such as low stomach acid, insufficient digestive enzymes, dysbiosis, and particularly Small Intestinal Bacterial Overgrowth (SIBO).

SIBO occurs when bacteria migrate from the large intestine to the small intestine, where they ferment undigested food and produce excess gases like hydrogen, methane, or hydrogen sulfide. This bacterial activity damages the intestinal lining, creating leaky gut, which allows toxins and undigested particles to enter the bloodstream and trigger systemic inflammation.

The consequences of leaky gut extend beyond the digestive system, including brain fog, chronic fatigue, sleep disturbances, hormone imbalances, skin issues, joint pain, and even cardiovascular inflammation. Functional medicine addresses these systemic symptoms by targeting the root cause.

Diagnosis relies on specialized tests like the SIBO breath test, which measures bacterial gases to determine the type of overgrowth and guide treatment. The core pillars of treatment include:

• Antimicrobials (pharmaceutical or herbal) to reduce bacterial overgrowth.
• Supporting digestion by restoring stomach acid and enzymes, and encouraging a “rest and digest” state.
• Restoring motility to prevent recurrence, addressing nerve damage, chronic stress, or other causes of slowed intestinal movement.

Dr. Jauregui emphasizes that gut health is a long-term journey. Even after healing, life events such as perimenopause or chronic stress may trigger recurrence, which requires reassessment and targeted interventions.

Dr. Monica Jauregui, MD, is a functional medicine physician who bridges conventional and holistic approaches to healthcare. After experiencing unresolved medical issues herself, she transitioned from traditional practice to functional medicine to focus on personalized, root-cause solutions for patients. Her expertise includes gut health, SIBO, digestive disorders, and systemic inflammation. She is passionate about educating patients and empowering them to achieve lasting wellness.
