Gut & Digestive Health
Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome (IBS) is a long-term condition that affects how your gut moves and reacts, often causing gas, pain, diarrhea, constipation, or a mix of both. And because IBS does not show up clearly on routine tests, many people are told everything looks “normal,” even when nothing feels normal.

Common Symptoms
- Abdominal pain or cramps (Often in the lower belly or around the navel)
- Bloating and gas
- Diarrhea, constipation, or both
- Changes in your bathroom pattern (Going more often, less often, or at very different times than before)
- A feeling of not being “done”
- Mucus in the stool
Likely Root Causes and Contributors
Researchers still do not have one single cause for IBS. Instead, IBS often comes from several imbalances working together.
- Brain–gut miscommunication
The gut and brain are in constant two-way contact. When those signals are off, the gut can overreact to normal movement or stretching. - Sensitive gut nerves (visceral hypersensitivity)
The nerves in your digestive tract can send stronger pain signals than they should. What would feel like a mild sensation for someone else can feel painful for you. - Irregular gut movement (motility changes)
Intestinal muscles may move food too fast, leading to diarrhea, or too slow, leading to constipation. - Changes in gut bacteria
Past infections, antibiotics, food poisoning, or diet shifts can change the balance of bacteria in your intestines. - Stress, Adrenal Fatigue, and the NEM circuits
Long-term stress can overload your NeuroEndoMetabolic (NEM) Stress Response. The Detoxification circuit and the Inflammation and Neuroaffect circuits are often involved. When these circuits are strained, inflammation can rise, detox slows, and the gut becomes more reactive to foods, hormones, and stress.


Patient Pain Points We Often Hear
“My stomach decides what kind of day I have. If I wake up crampy or bloated, I start changing plans in my head before I even get out of bed.”
“I get so bloated by the afternoon that I have to loosen my waistband or change clothes. I can eat the same thing two days in a row and one day I’m fine, the next day I’m miserable.”
“I’ve done the tests, the scopes, the blood work. Everything comes back ‘normal,’ but I’m still in pain, still running to the bathroom, and I’m starting to feel like no one really understands how much this affects my life.”
Our Approach to Healing
How We Map, Treat, and Sustain Real Recovery from IBS with the LAM Method™
IBS is personal. One person runs to the bathroom all morning. Another feels blocked and bloated for days. A third swings between both and never knows what their gut will do next. Our approach to healing uses the three phases of LAM Method™: Learn the Why, Address the Root, Maximize Longevity. Here’s how we use the LAM Method™ to address Thyroid Disorders:
Phase 1 of LAM Method™
Learn the Why of IBS
We start by reviewing your symptom timeline, triggers, sensitivities, and health history to understand what is driving your IBS.
IBS most often maps to the Inflammation circuit, with the Neuroaffect circuit commonly contributing when stress or poor sleep worsens symptoms.
Testing may include:
- Comprehensive Stool Test
- SIBO Breath Test
- Food Sensitivity Testing
- Liver and Detox Markers (bloodwork ± FibroScan when needed)
- Cortisol / Circadian Rhythm Testing
- Baseline Blood Panel

Phase 2 of LAM Method™
Address the Root of IBS
Once Lam Clinic sees your pattern, the next step is a plan that fits your IBS type and your sensitivity level. Support typically focuses on:
Lifestyle Foundations
- Targeted meal changes such as low FODMAP phases, smaller meals, and spacing meals.
- Fiber adjustments based on your IBS type so constipation is supported gently and diarrhea is not aggravated by the wrong fiber approach.
- Bowel-calming routines including light walking after meals and regular bathroom timing.
- Nervous system support such as breathwork or other calming tools to help reduce stress-driven flares through the gut-brain connection.
Targeted Supplement Support
- Probiotics to help rebalance the gut microbiome and support stool regularity
- L-glutamine to help support the gut lining and reduce irritation
- Soothing herbs like marshmallow root and slippery elm to help calm the digestive tract
IV Therapies
For patients who require additional support, we may incorporate:
- IV Nutrient Therapy
- IV Ozone Autohemotherapy
These therapies may help support hydration, nutrient status, and overall recovery during IBS flares or more depleted phases. Those with gut issues tend to have inadequate absorption of nutrients, so intravenous nutrient therapy allows the best form of nutrient therapy as it bypasses the gut.
This information is educational, not a prescription. Your actual plan is always individualized, adjusted slowly, and refined based on how your body responds.
Phase 3 of LAM Method™
Maximize Longevity
Once symptoms settle, we focus on staying stable:
- A personal trigger map and a flare response plan
- Food expansion so your diet does not keep shrinking
- A simpler long term routine for sleep, movement, and stress regulation
- Periodic check ins and retesting only when it changes decisions
NEM Response Circuits
How Your Body Regulate Stress
Your body handles stress through six interconnected circuits. When even one is out of balance, symptoms can show up in your heart, hormones, energy, and more.

Take the QuizFrequently Asked Questions
How does Lam Clinic approach IBS differently?
We do not stop at the label of “IBS” or a normal colonoscopy report and send you home with generic advice. Using The LAM Method™ and the NEM Stress Response model, we map which circuits like Detoxification, Inflammation, and Neuroaffect are overloaded and then build a stepwise plan that fits your body’s pace.
What foods should I avoid with IBS?
Common triggers include high FODMAP foods, dairy, beans, onions, wheat, and certain fruits, but triggers are different for each person. We help you identify your personal patterns so you can eat with more confidence and less guesswork.
Can stress really make my IBS worse?
Yes, stress can heighten pain, urgency, and bloating through the gut–brain connection and your NEM Stress Response. Calming the Neuroaffect and Detoxification circuits often helps symptoms become less intense and less frequent.
Why do my tests come back “normal” even though I feel terrible?
IBS usually does not show structural damage, so routine scopes and scans often look normal. At Lam Clinic, we look deeper at your microbiome, inflammation markers, NEM circuits, and stress patterns to understand what is actually driving your symptoms.
Can probiotics help with IBS?
For some people, the right probiotic at the right dose can support digestion, gas, and stool regularity. We often use options like Adrebiotics carefully and slowly, based on your sensitivity level and stool or microbiome findings.
Do you offer virtual visits and where are you located?
Yes, we offer secure telehealth visits worldwide and in person care at our clinic in Tustin, California. We proudly serve patients across Orange County, throughout the United States, and internationally who want personalized, NEM guided IBS support from the comfort of home.

The Lam Family has helped thousands recover from fatigue and stress for years.
Using advanced diagnostics and whole-body care, the Lam family looks beyond routine labs to uncover the real reasons behind fatigue—like adrenal stress, hormone imbalance, and nutrient depletion. Then, they create a personalized plan to help you heal fully and feel like yourself again.
The Pioneer of Root-Cause Healing & Whole Person Care
Before adrenal fatigue was widely understood, Dr. Michael Lam, M.D. led the way—developing one of the first clinical approaches to diagnose and treat it. His bestselling book, Adrenal Fatigue Syndrome, became a lifeline for patients around the world. Today, his children—Dr. Carrie Lam and Dr. Jeremy Lam—carry that legacy forward, building on his foundation with advanced diagnostics and whole-person care for lasting recovery.
