Gut Health & Digestive Concerns

Why Gut Health Matters

The digestive system plays an important role in breaking down food, absorbing nutrients, maintaining the intestinal barrier, and interacting with the immune system. The gastrointestinal tract is also home to a complex community of microorganisms known as the gut microbiome.

Research continues to explore how the microbiome, intestinal barrier, diet, immune system, and other factors interact in digestive health and disease. Changes in these systems have been associated with a variety of gastrointestinal conditions, although their role can differ considerably from person to person.

Digestive Symptoms We Work With

Digestive concerns can present in many different ways. Patients may seek care for symptoms such as:

• Bloating or excessive gas

• Abdominal discomfort or cramping

• Constipation

• Diarrhea or changes in bowel habits

• Acid reflux or heartburn

• Nausea

• Feeling overly full after eating

• Food-related digestive symptoms

These symptoms can have many possible causes. Persistent, severe, or changing gastrointestinal symptoms may require additional medical evaluation to identify or rule out underlying digestive conditions.

Our Approach to Gut & Digestive Health

Our approach begins with understanding your digestive symptoms, health history, nutrition, medications, lifestyle, previous testing, and any gastrointestinal diagnoses you may already have.

Depending on your needs, care may include nutrition and lifestyle recommendations, laboratory testing, supplements, medications when appropriate, and coordination with your primary care physician or gastroenterologist.

Personalized Nutrition

Nutrition recommendations are tailored to your symptoms, health history, nutritional needs, and individual response to different foods. Depending on the situation, your practitioner may recommend changes in meal patterns, fiber intake, specific foods, or a structured dietary approach when appropriate.

Digestive & Microbiome Testing

When appropriate, laboratory testing may be used as part of your evaluation. Depending on your symptoms and health history, this may include conventional laboratory testing, stool testing, breath testing, or other specialized testing.

Functional Medicine Collaborative also offers specialized gastrointestinal testing, including comprehensive stool testing and breath testing for suspected small intestinal bacterial overgrowth (SIBO). Test results are interpreted alongside your symptoms, medical history, and other clinical findings.

Digestive Conditions & Concerns We Work With

Our practitioners work with patients experiencing a variety of digestive symptoms, gastrointestinal conditions, and gut health concerns. These may include:

• Irritable bowel syndrome (IBS)

• Small intestinal bacterial overgrowth (SIBO)

• Constipation or chronic diarrhea

• Acid reflux and digestive discomfort

• Bloating and excessive gas

• Food-related digestive symptoms

• Microbiome-related concerns

• Concerns about intestinal permeability (“leaky gut”)

• Concerns about intestinal yeast or Candida overgrowth

• Inflammatory bowel disease (IBD), as supportive care alongside appropriate gastroenterology treatment

A Personalized 4R Approach to Gut Health

Depending on the patient's symptoms, health history, testing, and individual needs, our practitioners may use a 4R framework as part of a personalized approach to digestive health. The four areas—Remove, Replace, Reinoculate, and Repair—provide a framework for considering different factors that may be affecting digestion and gut health.

Not every patient requires every step, and recommendations are individualized rather than following the same protocol for everyone.

Remove

Identify and address factors that may be contributing to digestive symptoms. Depending on the individual, this may include certain foods, medications, infections, SIBO, intestinal yeast or Candida concerns, or other potential gastrointestinal irritants or triggers.

Replace

Support digestive function when needed. Depending on the patient's evaluation, recommendations may include nutrition changes, digestive enzymes, or other targeted support based on their individual digestive needs.

Reinoculate

Support the gut microbiome through individualized nutrition and, when appropriate, probiotics, prebiotics, fermented foods, or other recommendations based on the patient's needs and tolerance.

Repair

Support the intestinal barrier and overall digestive health through individualized nutrition, lifestyle recommendations, and targeted supplements when appropriate. For patients with concerns about increased intestinal permeability (“leaky gut”), recommendations are based on their symptoms, health history, nutritional needs, and other clinical findings.

Common Questions About Gut & Digestive Health

What causes chronic digestive symptoms?

Digestive symptoms can have many possible causes, including gastrointestinal conditions, infections, food intolerances, medications, changes in digestive function, and other health factors. Because symptoms such as bloating, constipation, diarrhea, reflux, and abdominal discomfort can occur with many different conditions, evaluation is individualized rather than assuming there is a single cause.

What is “leaky gut”?

“Leaky gut” is a commonly used term for increased intestinal permeability, which refers to changes in how substances pass through the intestinal barrier. Intestinal permeability is an active area of research and has been studied in connection with a number of gastrointestinal and other health conditions.

At Functional Medicine Collaborative, concerns about intestinal permeability are considered alongside your symptoms, medical history, nutrition, digestive health, and other clinical findings rather than assumed to be the cause of every symptom.

Do you test for SIBO?

When appropriate, breath testing may be considered for patients with symptoms or a health history that raises concern for small intestinal bacterial overgrowth (SIBO). Your practitioner will determine whether testing is appropriate and interpret the results alongside your symptoms and other clinical information.

Do you test for Candida or gut microbiome imbalances?

Depending on your symptoms and health history, your practitioner may recommend specialized stool or other laboratory testing to evaluate digestive health and the gut microbiome. Concerns about intestinal yeast or Candida may also be considered when clinically appropriate.

Specialized test results are interpreted alongside your symptoms, medical history, and other findings rather than used by themselves to determine the cause of your symptoms.

Do I still need a gastroenterologist?

Sometimes. Functional medicine and functional nutrition can complement care from a gastroenterologist, but they do not replace appropriate medical evaluation or treatment. Certain symptoms, diagnoses, or changes in your health may require evaluation by a gastroenterologist or another medical specialist.
