Your digestive system does more than break down food. It helps absorb nutrients, supports immune function, and interacts with many systems throughout your body.
When digestion is not working well, everyday life can become uncomfortable and unpredictable.
You may experience bloating after meals, abdominal discomfort, constipation, diarrhea, acid reflux, or reactions to foods you previously tolerated. You may find yourself avoiding certain meals, worrying about finding a bathroom, or wondering why your symptoms keep returning.
At Prolific Well Integrative Medicine in Olympia, Washington, I provide individualized evaluation and management of digestive health concerns, including irritable bowel syndrome (IBS), bloating, altered bowel habits, reflux, suspected small intestinal bacterial overgrowth (SIBO), and selected food-related symptoms.
My approach combines appropriate medical testing, clinical nutrition, evidence-informed treatment, and practical lifestyle strategies.
The goal is not simply to eliminate more foods or prescribe another supplement. It is to understand what may be contributing to your symptoms and develop a treatment plan that is medically appropriate and realistic for your life.
Schedule a Gut Health Consultation
Integrative digestive care combines conventional medical evaluation with nutrition, lifestyle medicine, and other therapies supported by appropriate clinical evidence.
Depending on your symptoms, evaluation may involve:
A detailed medical and dietary history
Review of medications and supplements
Physical examination
Blood and stool testing when indicated
Assessment for food allergies or intolerances
Screening for celiac disease
Evaluation for IBS or functional digestive disorders
SIBO breath testing in selected situations
Gastroenterology referral or endoscopic evaluation when appropriate
Individualized nutrition and treatment planning
Not every patient needs extensive laboratory testing.
Sometimes the most useful starting point is reviewing symptom patterns, bowel habits, dietary intake, medication effects, and previously completed testing.
Other times, symptoms suggest a condition that requires more urgent investigation.
My priority is to identify medically important causes first, then develop a practical plan for improving digestive health.
Irritable bowel syndrome is a disorder of gut-brain interaction characterized by recurring abdominal pain associated with bowel movement changes.
Symptoms may include:
Abdominal cramping or discomfort
Bloating and excessive gas
Constipation
Diarrhea
Alternating constipation and diarrhea
Changes in stool appearance or frequency
Symptoms that worsen after certain meals
What causes IBS?
IBS does not have one universal cause. Altered intestinal sensitivity, gut-brain signaling, bowel motility, previous gastrointestinal infections, and other factors may contribute.
Stress can influence symptoms through gut-brain pathways, but IBS is not simply caused by anxiety or imagined symptoms.
Evaluation focuses on identifying a symptom pattern consistent with IBS while assessing for warning signs and conditions that require different treatment.
Treatment may include dietary changes, soluble fiber, selected medications, gut-directed behavioral therapies, and other evidence-based interventions.
For appropriate patients, a time-limited low-FODMAP diet may help identify dietary triggers. It should generally be followed by structured food reintroduction rather than indefinite restriction.
Bowel habits vary from person to person, but persistent changes deserve attention.
Constipation may involve infrequent stools, hard stools, straining, or a sensation of incomplete evacuation.
Diarrhea generally involves loose or watery stools and may be acute or chronic.
Potential contributors include:
Inadequate fiber or fluid intake
Medication effects
IBS
Thyroid disorders
Celiac disease
Infections
Pelvic floor dysfunction
Inflammatory bowel disease
Other digestive or systemic conditions
Treatment depends on the cause.
For constipation, we may review fiber intake, hydration, medications, physical activity, and whether pelvic floor dysfunction is suspected.
For diarrhea, evaluation may include infection testing, celiac screening, inflammatory markers, medication review, or other investigations.
Persistent diarrhea should not automatically be treated as a food intolerance or microbiome imbalance.
Acid reflux occurs when stomach contents move backward into the esophagus.
Gastroesophageal reflux disease (GERD) involves troublesome or recurrent reflux symptoms or complications.
Common symptoms include:
Heartburn
Sour taste or regurgitation
Symptoms after meals
Nighttime reflux
Upper abdominal discomfort
Gastritis refers to inflammation of the stomach lining. Its causes may include Helicobacter pylori infection, certain medications, alcohol, autoimmune disease, and other factors.
Are acid reflux and gastritis the same thing?
No. GERD involves reflux into the esophagus, while gastritis involves inflammation of the stomach lining. They may produce overlapping symptoms but require different diagnostic considerations.
Depending on the situation, treatment may involve:
Reviewing meal timing and portion sizes
Identifying individual symptom triggers
Avoiding lying down soon after eating
Weight management when appropriate
Medication review
Acid-suppressing medications when indicated
Testing for H. pylori when appropriate
Referral for upper endoscopy when medically necessary
Persistent reflux, difficulty swallowing, gastrointestinal bleeding, or unexplained weight loss requires medical evaluation.
Small intestinal bacterial overgrowth (SIBO) refers to excessive bacterial populations in the small intestine that may contribute to digestive symptoms in certain patients.
Potential symptoms include:
Bloating
Abdominal distension
Excessive gas
Diarrhea
Abdominal discomfort
Sometimes constipation, particularly when intestinal methane overgrowth is involved
How is SIBO diagnosed?
Hydrogen and methane breath testing may be considered in selected patients based on their symptoms, risk factors, and clinical history.
However, breath testing has important limitations. Results require careful interpretation, and symptoms alone cannot confirm SIBO.
Not everyone with bloating has bacterial overgrowth.
When SIBO or intestinal methane overgrowth is suspected, I consider possible contributing conditions, testing options, and evidence-based treatments.
Treatment may involve prescription medication, nutrition support, and addressing underlying factors when identifiable.
Repeated antimicrobial or herbal protocols without reassessment are not always appropriate and may introduce unnecessary risks.
Food-related symptoms can occur for several reasons.
It is important to distinguish food allergy, food intolerance, celiac disease, and other gastrointestinal conditions because their evaluation and management differ.
Food allergies involve an immune response to a specific food and may cause hives, swelling, vomiting, respiratory symptoms, or anaphylaxis.
Food intolerances may involve difficulty digesting certain substances, such as lactose, or sensitivity to fermentable carbohydrates.
Celiac disease is an immune-mediated condition triggered by gluten in genetically susceptible individuals.
Common concerns include:
Symptoms after dairy products
Bloating after wheat-containing foods
Reactions to high-FODMAP foods
Recurrent digestive symptoms after specific meals
Concern about gluten sensitivity
Multiple self-reported food reactions
A food and symptom diary may help identify patterns.
When celiac disease is suspected, appropriate testing should generally be performed before eliminating gluten, because removing gluten can interfere with diagnostic accuracy.
Broad food IgG panels are not recommended for diagnosing food allergies or intolerances.
My goal is to identify meaningful triggers while preserving nutritional adequacy and avoiding unnecessarily restrictive diets.
Inflammatory bowel disease includes Crohn's disease and ulcerative colitis.
Unlike IBS, IBD involves intestinal inflammation that can lead to tissue damage and complications.
Symptoms may include:
Persistent diarrhea
Blood in the stool
Abdominal pain
Unintentional weight loss
Fatigue
Nutritional deficiencies
IBD requires appropriate diagnosis, monitoring, and medical treatment, typically in collaboration with a gastroenterologist.
At Prolific Well, integrative support may focus on:
Nutritional adequacy
Identification and management of deficiencies
Bone health
Appropriate dietary modifications
Medication and supplement review
Sleep, stress, and quality-of-life support
Coordination with gastroenterology care
Nutrition and lifestyle medicine can complement IBD treatment, but they should not replace necessary anti-inflammatory, immunomodulatory, or biologic therapy.
Patients with significant bleeding, severe abdominal pain, fever, dehydration, or other concerning symptoms may need urgent medical attention.
Your gut microbiome includes microorganisms that live throughout the digestive tract.
These organisms participate in processes involving digestion, fermentation of dietary fiber, production of certain metabolites, and immune interactions.
Microbiome research is expanding our understanding of digestive and metabolic health.
However, a microbiome test does not automatically identify the cause of digestive symptoms, and many commercially available microbiome profiles have limited established clinical utility.
When considering testing, I ask:
What clinical question are we trying to answer?
Is the test validated for that purpose?
Will the result meaningfully change treatment?
Are more established diagnostic tests indicated first?
What are the financial costs and potential downsides?
For many patients, the first steps involve improving dietary diversity, evaluating specific symptoms, and using established diagnostic methods.

Seek prompt medical evaluation for rectal bleeding, black or tarry stools, unexplained weight loss, persistent vomiting, progressive difficulty swallowing, or significant changes in bowel habits.
Severe abdominal pain, vomiting blood, fainting, or signs of significant dehydration may require emergency care.
We begin by discussing your symptoms, bowel patterns, dietary habits, medications, supplements, medical history, and previous evaluations.
I also want to understand how digestive symptoms affect your everyday life.
Depending on your symptoms, testing may include:
Complete blood count and metabolic testing
Celiac disease screening
Thyroid testing when indicated
Stool testing for infections
Fecal calprotectin when intestinal inflammation is suspected
H. pylori testing
Selected SIBO breath testing
Nutrient testing when deficiency is suspected
Gastroenterology referral for colonoscopy or endoscopy when appropriate
Not every patient needs every test.
Treatment may include:
Medical nutrition therapy
Appropriate fiber and hydration strategies
A structured low-FODMAP trial when indicated
Food reintroduction and dietary liberalization
Prescription medications
Treatment of identified infections
Targeted supplementation when justified
Gut-directed behavioral therapies
Management of contributing medical conditions
Specialist collaboration
The plan should be based on the diagnosis, not a generic gut cleanse.
We review symptom response, nutritional status, treatment tolerance, and whether further evaluation is needed.
The goal is sustainable improvement while maintaining a varied, nourishing diet whenever possible.
In my practice, I often see patients who have already eliminated gluten, dairy, sugar, or several other foods because they are trying to feel better.
Some have purchased multiple supplements or completed restrictive digestive protocols without understanding what is actually causing their symptoms.
I understand why this happens. When your stomach hurts, you feel bloated after eating, or your bowel habits are unpredictable, you want relief.
But I do not believe that the answer is always another elimination diet or another expensive test.
The digestive system interacts with nutrition, medications, the nervous system, immune function, and metabolic health.
That is why I look at the whole picture while remaining focused on identifying the specific condition that needs treatment.
Sometimes the answer is straightforward, such as addressing constipation or lactose intolerance.
Other times we need to evaluate for celiac disease, inflammatory conditions, infection, or another diagnosis.
My philosophy is to investigate thoughtfully, treat appropriately, and help patients return to eating with greater confidence rather than fear.
While treatment should be individualized, several foundational habits may support digestive health.
1. Eat a variety of fiber-containing foods. Vegetables, fruits, legumes, nuts, seeds, and whole grains provide different types of fiber. Increase fiber gradually when appropriate, especially if bloating is an issue.
2. Stay adequately hydrated. Fluid needs vary with activity, climate, medications, and health conditions.
3. Move regularly. Physical activity can support overall health and may help some people with constipation.
4. Pay attention to symptom patterns. A brief food and symptom diary may be more useful than eliminating many foods at once.
5. Review medications and supplements. Iron, magnesium, antibiotics, anti-inflammatory drugs, and other products can affect digestion.
6. Avoid unnecessary dietary restriction. A highly restrictive diet may increase the risk of nutrient deficiencies and make eating more stressful.
7. Seek evaluation for persistent symptoms. Ongoing abdominal pain, diarrhea, constipation, or reflux deserves an appropriate assessment.
You do not need a perfect diet to begin supporting your digestive health.

A primary care clinician can evaluate many common digestive concerns, including bloating, constipation, diarrhea, and reflux. A gastroenterologist may be needed for persistent, complex, or concerning symptoms. At Prolific Well, Dr. Evelyn Le Ellis provides initial evaluation and appropriate integrative management within her clinical scope.
Yes. A Washington-licensed naturopathic physician can evaluate IBS symptoms, assess for other causes, and recommend appropriate nutrition, lifestyle, and medical treatment. Referral to gastroenterology may be needed in certain situations.
No. Bloating can result from constipation, IBS, food intolerances, altered gut sensitivity, medications, and other conditions. SIBO is only one possible explanation.
Symptoms alone cannot confirm SIBO. Hydrogen and methane breath testing may be considered in selected patients, but testing has limitations and should be interpreted alongside clinical findings.
The gastrointestinal system participates in nutrient absorption and metabolism, and gut microorganisms may influence certain hormone-related pathways. However, current evidence does not support attributing most hormone symptoms to microbiome imbalance without appropriate medical evaluation.
Probiotics are not universally helpful. Effects vary by strain, condition, and individual response, and evidence is inconsistent for many digestive indications. Some people experience increased gas or bloating. Recommendations should be individualized.
Not necessarily. Commercial microbiome tests may provide interesting information, but many are not sufficiently validated to diagnose specific conditions or guide treatment. Established diagnostic testing is usually prioritized.
No. There is no single reliable test that identifies every food intolerance. Clinical history, targeted testing, and structured dietary trials may be more useful. Food IgG panels are not recommended for diagnosing food intolerance.
Often, yes. Depending on the diagnosis, treatment may focus on bowel regularity, adequate nutrition, fiber modification, medication management, and other targeted interventions without extensive food elimination.
Prolific Well can provide supportive integrative care for patients with IBD, including nutrition and general health management, while coordinating with gastroenterology. IBD-specific medical treatment and monitoring remain essential.
Coverage depends on your insurance plan, network, diagnosis, testing, and services provided. Certain specialty tests or non-covered services may require out-of-pocket payment.
