What Is SIBO?

Small Intestinal Bacterial Overgrowth (SIBO) is a digestive condition where an abnormal amount of bacteria accumulate in the small intestine. This bacterial imbalance can interfere with digestion, nutrient absorption, and normal gut function, often leading to symptoms such as bloating, gas, abdominal discomfort, constipation, diarrhea, and food sensitivities.

A functional medicine approach to SIBO focuses on identifying the underlying factors contributing to bacterial overgrowth while supporting healthy digestion and gut balance.

At our functional medicine practice, we create individualized SIBO treatment plans that may include nutrition support, herbal supplementation, digestive support, and lifestyle strategies designed to improve gut health.

SIBO Symptoms: What Does SIBO Feel Like?

SIBO symptoms can vary depending on the individual and the type of bacterial overgrowth present. Common symptoms include:

• Persistent bloating, especially after meals
• Excessive gas
• Abdominal pain or cramping
• Constipation
• Diarrhea
• Alternating constipation and diarrhea
• Feeling full quickly after eating
• Acid reflux or indigestion
• Food sensitivities
• Fatigue
• Brain fog
• Nutrient deficiencies

Many people with SIBO notice that certain foods trigger symptoms and even some supplements such as probiotics can make symptoms worse.

How Does SIBO Develop?

SIBO is often not caused by one single issue. Instead, it usually develops when the normal protective mechanisms of the digestive tract become disrupted.

Factors that may contribute to SIBO include:

Poor Gut Motility

The digestive tract has a natural cleansing process called the migrating motor complex, which helps move bacteria and food particles through the small intestine. When movement slows, bacteria may remain in the small intestine and multiply.

Low Stomach Acid

Adequate stomach acid helps break down food and provides protection against unwanted bacteria entering the small intestine.

Previous Digestive Infections

Food poisoning or gastrointestinal infections may affect the nerves and movement of the intestines, increasing the risk of bacterial overgrowth.

Digestive Imbalances

Chronic digestive issues, inflammation, intestinal permeability, and nutrient deficiencies may contribute to an unhealthy gut environment.

Poor Diet

A diet high in processed foods, refined carbohydrates, added sugars, and frequently consumed fermentable carbohydrates may contribute to an environment that supports unwanted bacterial growth by providing fuel for bacteria in the digestive tract. Over time, poor dietary patterns combined with impaired digestion or gut motility may increase the risk of bacterial imbalance and SIBO symptoms.

SIBO Diet: Nutrition Support for Healing

A common question is, “What is the best SIBO diet?” While dietary needs vary from person to person, nutrition is an important part of supporting recovery.

A functional medicine approach does not focus on long-term extreme restriction. Instead, the goal is to identify food triggers while improving digestion and restoring balance. A lot of the time it is not as simple as following a low FODMAP diet and the SIBO magically goes away.

Nutrition strategies may include:

Prioritizing Protein

Protein supports tissue repair, blood sugar balance, and overall health. Including adequate protein at meals can help support digestive function and reduce cravings.

Reducing Processed Foods and Excess Sugar

Highly processed foods and excess sugar may contribute to digestive discomfort and microbial imbalance in some individuals.

Supporting Digestion

Strategies may include:

• Eating slowly and chewing thoroughly
• Avoiding constant snacking
• Creating space between meals
• Supporting stomach acid and digestive enzyme function when appropriate

Individualizing Fiber Intake

Some individuals with SIBO tolerate fiber well, while others experience increased bloating with certain types. Fiber recommendations should be personalized by a functional medicine practitioner.

Functional Medicine Treatment for SIBO

A functional medicine approach to SIBO looks beyond the presence of bacterial overgrowth and focuses on why the imbalance developed. Dr. Julia Augustyniak uses Applied Kinesiology to customize each supplement protocol based on what each patient needs.

Our SIBO treatment approach may include:

Herbal Treatment for SIBO

Certain herbs have been researched for their ability to support microbial balance and digestive health.

At our office, herbal supplementation is personalized based on each patient’s symptoms, health history, and individual needs.

Supporting Gut Function

Effective SIBO treatment often includes supporting the digestive system as a whole by focusing on:

• Healthy digestion
• Gut motility
• Nutrient absorption
• Intestinal lining support
• Dietary triggers
• Lifestyle factors

Addressing the Root Cause

One of the biggest differences between a symptom-focused approach and functional medicine is the focus on identifying contributing factors.

We evaluate areas such as:

• Digestive history
• Bowel patterns
• Nutrition
• Stress
• Lifestyle factors
• Previous infections
• Gut health concerns
