Our Integrated Approach to Diagnosis and Treatment
Every condition begins with a detailed, unhurried evaluation. Your doctor reviews your medical history, prior testing, medications, supplements, diet, stress, and sleep to understand the full picture. From there, care draws on three core service areas:
Analytical Services – functional medicine diagnostics, nutritional assessment, inflammation and oxidative stress evaluation, and advanced lab work that reveal underlying causes.
Technical Services – colonoscopy, upper endoscopy, capsule endoscopy, breath testing, and anorectal manometry to directly evaluate the digestive tract.
Nutritional Services – customized nutrition plans, therapeutic digestive disorder diets, and targeted nutraceutical supplements that support healing.

Gastrointestinal Conditions FAQs
What is the difference between a food allergy and a food sensitivity?
A food allergy is an immune reaction that can cause immediate and sometimes severe symptoms and is usually identified with standard allergy testing. A food sensitivity causes delayed digestive or whole-body symptoms that can appear hours or days later, making it harder to identify without structured testing and elimination protocols.
Why do I still have bloating if my colonoscopy was normal?
A normal colonoscopy rules out structural problems in the colon, but it does not evaluate small intestine function or microbial balance. Bloating often comes from SIBO, dysbiosis, or food intolerances, which we assess with breath testing, dietary analysis, and advanced stool testing.
Can GERD be managed without long-term medication?
Many patients improve with a root-cause plan that addresses trigger foods, digestion, stress, weight, and nutrient status. Some patients benefit from medication for a period of time, and your doctor will recommend the safest approach for your situation. Learn more on our GERD page.
How long does SIBO treatment take?
Treatment usually combines dietary changes, targeted antimicrobial therapy, and nutritional support. Many patients notice improvement within several weeks, while full recovery and prevention of relapse can take a few months depending on the underlying cause.
Can digestive problems cause fatigue?
Yes. When the gut does not absorb nutrients such as iron, B vitamins, and magnesium properly, or when chronic inflammation is present, energy can suffer. Our fatigue evaluation looks for these digestive contributors.
What happens at my first visit?
Your first consultation includes a thorough review of your history, symptoms, diet, lifestyle, and prior testing, followed by an exam and recommendations for targeted labs or procedures. You will leave with clear next steps and a personalized plan.

Yes. We also evaluate celiac disease, Crohn’s disease, IBS, and other gut-related concerns. Visit our More Conditions page or call LA Integrative Gastroenterology & Nutrition at (310) 289-8000 to ask about your specific symptoms.
