What is SIBO?

gut health and SIBO

Before we dig into some potentially beneficial probiotics to help treat SIBO, let’s first chat a bit about what exactly it is and how symptoms may present.

SIBO stands for small intestinal bacterial overgrowth and it means that the bacteria that live in your small intestine have overgrown, leading to an imbalance in your gut flora. While having bacteria living in your small intestine is very normal and healthy, too many can cause issues with digestion, particularly if it’s the wrong kind.

If you have too much of the wrong kind of bacteria in your small intestine, it can start to overwhelm the good bacteria, disrupting your whole digestive system. SIBO occurs when one or more of the complex networks of chemical and mechanical functions in your body fails. 

What Are the Symptoms?

SIBO symptoms vary from person to person, but often include the following:

  • Loss of appetite
  • Abdominal pain
  • Nausea
  • Gas
  • Indigestion
  • Fatigue
  • Bloating
  • Uncomfortable fullness after eating
  • Diarrhea
  • Malnutrition
  • Unintentional weight loss

Can A Probiotic Help With SIBO?

Yes, studies have shown that probiotics can be an effective treatment for SIBO when used alone or in combination with other research-backed treatments. Beyond treating SIBO symptoms, using a probiotic can help resolve digestive symptoms, non-digestive symptoms, and chronic inflammatory conditions, helping to improve your overall health.

As with any supplement you’re considering, you should always speak with your doctor about whether or not it’s a good choice for you and your treatment plan. However, research indicates that probiotics can be a helpful treatment for SIBO and many other digestive and immune system-related issues.

Buying Guide: Here’s What to Look For

choosing probiotic for SIBO

As you navigate the buying process, here are a few things to consider and look out for:

SBO (Soil Based Probiotics)

There’s some research and evidence that shows that SBO probiotics might be more beneficial for those who have been diagnosed with SIBO. Soil-based probiotics are those that only contain bacteria naturally found in the soil, giving us the same bacteria that we consumed from our food before sterilizing farming techniques were introduced.

Synbiotic

A synbiotic is a probiotic that also contains a prebiotic and maybe even a postbiotic. When all three components are combined together, you get the most functionality from your bacteria, providing them with well-rounded support so that they can then support your gut and intestines properly.

Clinically-Studied Strains

Read the nutrition label carefully when selecting a probiotic to ensure that there are clinically studied strains that are shown to improve your specific symptoms. 

Brand Reputation and Quality

While it can be tempting to grab any old probiotic off the store shelf, it’s important to do your due diligence first to ensure that the brand you’re purchasing is legit. Do they use third-party testing? Where are their ingredients sourced from? What are their customers saying about their experience and results?
