Understanding Changes in Your Breath Test Results

Understanding Erratic Breath Readings

It can sometimes feel worrying or confusing if your breath readings look a little inconsistent. You’re not alone — many people notice changes from time to time, and often there are simple explanations.

Here are a few things to keep in mind:

1. Have you recently started SIBO treatment or an elemental diet?

When treating SIBO, your gut microbiome is going through significant changes. During this process, it’s normal for fermentation levels to appear a bit unpredictable.

What you can do:

• Keep monitoring your fermentation levels regularly. Daily breath testing can give you a clearer picture of how things are shifting over time.
• If you ever feel unsure, reach out to your healthcare practitioner. They know your medical history best and can guide you safely through your treatment plan. Remember, SIBO is a complex condition, and professional support is important to ensure the best outcomes.

2. Have you started any new supplements or medications?

Changes in your supplement or medication routine — even beneficial ones — can influence your microbiome and may affect your breath readings.

Things to consider:

• Probiotics, prebiotics, and antibiotics are all common factors that may shift your daily results.
• Keep track of when you start something new, so you can connect any changes in your readings with changes in your routine.

3. Could lifestyle changes be playing a role?

Your gut health is closely connected to your overall wellbeing. Stress, sleep, and exercise can all influence digestion and fermentation patterns.

👉 Examples:

• Poor or disrupted sleep may impact your gut and show up in your scores.
• Exercise is hugely beneficial, but intensive training programs can temporarily stress the body and digestion.
