Introduction: Why IBS Needs a Root-Cause Approach

Irritable Bowel Syndrome (IBS) disrupts the daily lives of millions. At Patients Medical in New York City, we don’t settle for symptom management—we investigate why your gut is out of balance. Through a combination of functional, holistic, and conventional medicine, we address IBS at its root.

Because a healthy gut means a healthy life.

What is IBS (Irritable Bowel Syndrome)?

IBS is a functional gastrointestinal disorder, meaning it affects how your gut works—but doesn’t show up on standard medical tests. Symptoms include:

  • Abdominal pain or cramping
  • Bloating and gas
  • Diarrhea, constipation, or both
  • Mucus in stool

IBS can fluctuate with stress, food, and hormone changes. It’s often diagnosed when other digestive conditions are ruled out.

What Causes IBS? – Root Factors in Functional Medicine

There’s no single cause of IBS. Functional medicine looks at multiple triggers that can create inflammation, nervous system dysregulation, and digestive imbalance:

Advanced IBS Testing at Patients Medical

We go beyond routine labs to uncover hidden imbalances:

  • Comprehensive stool microbiome testing
  • SIBO breath test (methane & hydrogen gases)
  • Food sensitivity and IgG testing
  • Zonulin (leaky gut marker)
  • Cortisol/adrenal stress panels
  • Organic acids (to assess gut fermentation, yeast overgrowth)
  • Hormone and thyroid panels
  • Mold, heavy metal, and mycotoxin testing

Our Integrative IBS Treatment Protocol

Customized Nutrition Plans

Based on lab results, we create gut-healing plans using:

  • Low FODMAP or elimination diets
  • Anti-inflammatory Mediterranean-style nutrition
  • Rotational food planning
  • Digestive support (enzymes, bitters)

IV Therapy for Gut Support

Personalized IVs may include:

  • Glutathione (gut barrier repair)
  • B-complex and magnesium (nervous system calming)
  • Vitamin D and zinc (immune and mucosal support)
  • Antioxidants for inflammation

Stress & Vagus Nerve Healing

We offer:

  • Meditation and breathwork
  • Acupuncture
  • Vagus nerve stimulation techniques
  • Adaptogenic herbs for adrenal support

Herbal & Nutraceutical Protocols

Evidence-backed support like:

  • L-glutamine & slippery elm (gut lining repair)
  • Berberine & oregano oil (natural antimicrobials)
  • Probiotics and prebiotics
  • Magnesium citrate or oxide (for constipation-dominant IBS)
  • Herbal stress support (ashwagandha, rhodiola)

Hormonal & Thyroid Balancing

IBS symptoms are often worse around menstruation, menopause, or thyroid dysfunction. We test and balance hormones to improve gut regularity.

Real Case Study: Jason’s IBS Relief Story

Jason, 39, came to us after years of alternating diarrhea and constipation, fatigue, and anxiety. GI specialists had ruled out IBD but labeled it “IBS.”

We discovered:

  • Elevated methane on SIBO test
  • Gluten sensitivity
  • Low cortisol and adrenal burnout
  • Gut inflammation markers

Treatment included:

  • 6-week antimicrobial protocol
  • Gluten-free, low-FODMAP diet
  • Probiotic rotation
  • IV glutathione and adrenal support

Within 8 weeks, Jason’s symptoms decreased by 80%. After 3 months, his digestion normalized, and his energy returned.

Frequently Asked Questions

IBS is a functional disorder with no visible inflammation or damage. IBD (like Crohn’s or ulcerative colitis) shows clear inflammation and can cause lasting tissue damage.

Yes, up to 80% of people with IBS test positive for SIBO. It’s a major underlying cause of gas, bloating, and irregular bowels.

Absolutely. The gut and brain are deeply connected. Chronic stress disrupts digestion, motility, and microbiome balance.

Common triggers include gluten, dairy, caffeine, alcohol, high FODMAP foods, and artificial sweeteners.

Yes—many patients experience complete or near-complete resolution of symptoms through root-cause treatment.

Not necessarily. We use temporary elimination diets to identify triggers, then work toward long-term flexibility and food freedom.

Yes. IBS is linked with anxiety and depression due to gut-brain axis dysfunction and neurotransmitter imbalances in the gut.

This could be due to SIBO or histamine intolerance. We tailor probiotics based on your specific needs.

Most patients see improvement within 4–8 weeks. Full healing may take 3–6 months depending on complexity.

We are out-of-network but provide superbills for possible reimbursement. Some labs may be covered by insurance.
