Small Intestinal Bacterial Overgrowth (SIBO) is an often-overlooked condition that can cause a wide range of digestive issues. Many people struggle with bloating, gas, diarrhea, constipation, and stomach discomfort without realizing that an imbalance of bacteria in the small intestine may be to blame. If you're wondering whether you have SIBO and what to do about it, read on.

Symptoms of SIBO

SIBO symptoms can mimic other digestive disorders, making it tricky to diagnose. Common signs include:

  • Chronic bloating and distension

  • Excessive gas

  • Diarrhea, constipation, or alternating between both

  • Stomach pain or discomfort after eating

  • Unexplained weight loss or nutrient deficiencies

  • Fatigue and brain fog

If these symptoms persist despite dietary changes or other treatments, SIBO might be a factor.

How to Diagnose SIBO

The most common way to diagnose SIBO is through a breath test that measures hydrogen and methane gases produced by bacteria in the small intestine. This test involves consuming a sugar solution and then measuring the gases exhaled over a period of time.

Other diagnostic methods may include:

  • Stool tests to rule out other gut imbalances

  • Blood tests for nutritional deficiencies

  • Small intestine aspirate and culture (less common but considered the gold standard)

How to Treat SIBO

Treatment for SIBO typically involves a combination of dietary changes, antibiotics or herbal antimicrobials, and lifestyle adjustments. Here’s a breakdown of common approaches:

1. Antibiotics or Herbal Treatments

Conventional treatment often includes antibiotics such as rifaximin, which targets bacteria in the small intestine. Alternatively, herbal antimicrobials like oregano oil, berberine, and allicin have shown effectiveness in reducing bacterial overgrowth.

2. Dietary Changes

Many people find symptom relief through dietary adjustments. Common approaches include:

  • Low FODMAP Diet – Reducing fermentable carbohydrates that feed bacteria.

  • Elemental Diet – A short-term liquid diet that starves bacteria while providing essential nutrients.

  • Specific Carbohydrate Diet (SCD) or Gut and Psychology Syndrome (GAPS) Diet – Designed to heal the gut by eliminating certain carbs and sugars.

3. Prokinetics for Gut Motility

Prokinetic agents like ginger, low-dose erythromycin, or prucalopride help prevent SIBO recurrence by supporting proper gut motility and reducing bacterial stagnation.

4. Lifestyle Adjustments

Factors like stress and poor sleep can contribute to SIBO. Incorporating stress management techniques, proper hydration, and movement (such as yoga or walking) can help improve gut function.
