Gut microbiome analysis: Discover how your gut health works
ca. 20 Minuten
A gut microbiome analysis is a modern health test that helps you discover the composition of the trillions of microorganisms in your gut. All you need is a simple stool sample, which you can conveniently collect at home. This sample is used to decode your unique microbiome and identify any potential imbalance (dysbiosis) that could be behind a range of symptoms.
Understanding your gut as an ecosystem
Don’t think of your gut simply as an organ, but rather as a thriving, living ecosystem. In this complex system—your gut microbiome—trillions of microorganisms (bacteria, viruses, and fungi) live and work for you every single day. They’re absolutely essential to your health and affect far more than just your digestion.
These tiny helpers are true all-rounders. They support your immune system, around 70% of which is located in the gut, produce important vitamins, and even influence your mood and mental state through the gut-brain axis. As long as this ecosystem is in balance, you feel fit, energized, and good all around.
When the balance is disrupted
But what actually happens when this delicate system gets out of balance? Such a disruption, also known as dysbiosis, can cause a whole range of nonspecific symptoms that you might not immediately associate with your gut.
These include, for example:
- Constant bloating and irregular digestion
- Persistent fatigue and a lack of energy in everyday life
- Skin problems such as acne, eczema, or a dull complexion
- Unexplained weight fluctuations or difficulty losing weight
Many people turn to one-size-fits-all diets or well-meaning advice to address these complaints, but these often don’t match the underlying cause. So you don’t have to keep guessing, a targeted gut microbiome analysis can finally give you clarity.
You’re not alone in experiencing digestive problems. A 2024 study shows that three out of five Germans suffer from intestinal complaints. This highlights how important it is to take your gut health seriously and take proactive steps. Learn more about the latest findings in the Mintel Gut Health Market Report.
Personalized, not one-size-fits-all
Rather than just treating symptoms, you’ll get to the root cause with an analysis. A self-test like the mybody-x gut test gives you a detailed snapshot of your inner ecosystem. It shows you exactly which bacterial strains are prevalent, where there may be a deficiency, and how diverse your tiny gut inhabitants are.
With this knowledge, you’ll learn to finally interpret your body’s signals correctly. You’ll discover why a personalized approach, tailored to the specific needs of your microbiome, is the key to lasting well-being. Rather than following general recommendations, you’ll get a clear plan tailored to your unique body.

Analysis using state-of-the-art technology
As soon as your sample arrives at the laboratory, the scientific work begins. This is where state-of-the-art technology comes in to decode the unique ecosystem in your gut.
Using a method called 16S rRNA gene sequencing, the DNA of your gut bacteria is analyzed. Think of it as taking a genetic fingerprint of each individual bacterial strain. This allows the laboratory to determine exactly which bacterial species live in your gut and in what quantities.
This process makes it possible to create a detailed profile of your microbiome. It shows not only the diversity of the microorganisms in your gut, but also the relative proportions of important bacterial groups.
At mybody-x, your sample is analyzed exclusively at an ISO 15189-certified specialist laboratory in Germany. This certification is an internationally recognized quality standard for medical laboratories and guarantees the highest precision and reliability in your results.

Deciphering your results and really understanding them
You hold your results in your hands - a detailed report full of scientific terms, numbers, and charts. At first glance, it can seem pretty intimidating. But don't worry: this report isn't a complicated lab file, it's your very own roadmap to greater well-being. Together, we'll now translate the most important findings from your gut microbiome analysis into clear, practical insights for everyday life.
This section gives you the tools to decode your results and finally understand where you can start. You’ll see how the data suddenly explain your symptoms - whether bloating, fatigue, or skin problems - and show you the way to targeted improvements.
The following graphic clearly shows the journey your sample takes from your home to the completed analysis in the lab.
Every step, from the test kit and sample collection to the lab analysis, is designed to provide you with precise and reliable data about your microbiome.
The diversity of your microbiome
One of the most important values in your results is bacterial diversity. Picture your gut as a flourishing garden. A healthy garden doesn’t thrive on just one plant species, but on a colorful mix of flowers, herbs, and shrubs. They all support one another and make the whole ecosystem resilient.
That’s exactly how it works in your gut, too. A wide variety of bacterial species makes your microbiome resilient to disruptions. It can better defend itself against harmful germs, make optimal use of nutrients, and perform important functions for your immune system. Low diversity, on the other hand, makes the system vulnerable and is often linked to chronic inflammation, digestive problems, and even difficulty losing weight.
The Firmicutes-Bacteroidetes ratio
Another key measurement is the ratio of the two major bacterial phyla, Firmicutes and Bacteroidetes. These two groups dominate our gut and have a huge impact on our metabolism and body weight.
- Bacteroidetes are considered the “slim” bacteria. They’re experts at breaking down complex carbohydrates (that is, fiber) while making fewer calories available to the body.
- Firmicutes, on the other hand, are especially efficient at extracting energy. They get more energy from the same food and tend to store excess energy as fat.
An imbalance favoring Firmicutes can mean that your body extracts more calories than average even from healthy foods. That can make it damn difficult to maintain your weight or lose weight, even if you eat mindfully.
Your report shows your personal ratio of these bacterial groups. This information is invaluable because it explains why generic diets might not work for you and how you can tailor your diet to bring your microbiome back into balance.
Important bacteria and their functions
In addition to the major groups, a good gut flora analysis also looks at specific bacterial species and their functions. One very important example is butyrate-producing bacteria. Butyrate is a short-chain fatty acid that serves as the main energy source for your intestinal cells.
It strengthens the intestinal barrier, reduces inflammation, and promotes a healthy gut environment. A deficiency in butyrate producers, such as Faecalibacterium prausnitzii, is often found in people with irritable bowel syndrome, bloating, or chronic inflammatory bowel diseases. If your report shows such a deficiency, you’ll know exactly what to work on: specifically, eating foods that promote the growth of these beneficial bacteria.
The following table gives you a quick overview of the most important measurements and what they mean for you.
Key measurements in your gut flora analysis and what they mean This table explains the key parameters in a microbiome report and what they mean for your health.
| Measurement | What it means | Potential effects of imbalances |
|---|---|---|
| Bacterial diversity | The number of different bacterial species in your gut. A high value is a sign of a healthy, stable microbiome. | Low diversity is associated with digestive problems, inflammation, and increased susceptibility to infections. |
| Firmicutes/Bacteroidetes ratio | The balance between the two most dominant bacterial phyla, which have a strong influence on energy metabolism. | A higher Firmicutes proportion may mean more efficient calorie absorption, making it harder to maintain or lose weight. |
| Butyrate-producing bacteria | Beneficial bacteria that produce butyrate - a fatty acid that strengthens the intestinal wall and reduces inflammation. | A deficiency can lead to a weakened intestinal barrier (“leaky gut”), bloating, and an increased risk of chronic intestinal diseases. |
| Akkermansia muciniphila | An important bacterium that nourishes the intestinal lining and is associated with a healthy metabolism and body weight. | Low levels are often observed in people with obesity, type 2 diabetes, and inflammatory conditions. |
| Potentially harmful bacteria | Bacteria that are normally present in small amounts but can cause problems if they overgrow (e.g., certain Clostridia). | Excessive amounts can cause gas, bloating, diarrhea, or inflammation and disrupt the balance of the gut flora. |
This information will help you better understand your results and recognize how they relate to your well-being.
If you’d like to learn more about how analysis results are interpreted and what they mean, you’ll find a detailed explanation of microbiome analysis in our in-depth article.
The results of a mybody-x gut test don’t just provide you with this raw data. They translate it directly into easy-to-understand charts and, more importantly, personalized recommendations. This way, you’ll find out exactly which foods and lifestyle changes can help you increase diversity, optimize the Firmicutes-Bacteroidetes ratio, or boost butyrate production.
From knowledge to action: Your personal roadmap
A gut flora analysis is only as good as the plan that comes out of it. Think of your results as a map of your inner ecosystem - now it’s time to set off on the journey. This section is all about practical steps: we’ll show you how to turn the insights from your microbiome profile into concrete everyday strategies and create your personal roadmap to a healthier gut.
You’ll quickly realize that this isn’t about one-size-fits-all advice. Instead of blindly following some diet or other, you start supporting your body in a targeted way and building up exactly what it lacks.
Feed your good bacteria with prebiotics
The key to a healthy microbiome often lies in specifically “feeding” your beneficial bacterial strains. That’s where prebiotics come in. These are special, indigestible fibers that serve as favorite foods for your good gut inhabitants and give their growth a powerful boost.
But not every prebiotic food is equally beneficial for everyone. Your analysis results reveal which of your bacteria especially need an extra helping of food. For example, if you lack butyrate-producing bacteria, foods rich in resistant starch are your trump card.
Here are some examples of targeted prebiotic eating:
- Resistant starch: Forms when you cook starchy foods such as potatoes, rice, or pasta and then let them cool. It’s the absolute favorite food of many butyrate producers.
- Inulin: Found mainly in chicory, Jerusalem artichokes, artichokes, and onions. It specifically promotes the growth of bifidobacteria.
- Pectins: Found in abundance in apples, carrots, and berries. They support a diverse gut flora and help strengthen the gut barrier.
Boost your diversity with probiotics
While prebiotics feed the beneficial bacteria you already have, probiotic foods deliver new, live microorganisms directly to your gut. They’re like fresh reinforcements for your team and can help increase bacterial diversity and restore balance to a microbiome that’s out of sync.
Here, too, targeted use is key. Kefir, yogurt, raw sauerkraut, kimchi, and kombucha all contain very different bacterial strains. Your results can offer valuable clues about which types of probiotic foods may be especially beneficial for you. One specific approach may be to support your gut flora with live microorganisms, such as those used in studies involving people to improve gut health. Research in other areas is also relevant in this context, such as probiotics for dogs, where very similar principles are applied.
Your plan is as unique as you are
General recommendations often only go so far. The real value of a gut flora analysis lies in personalization. Let’s look at two fictional examples to make this more tangible:
Case study A: Lena, 34, suffers from constant bloating and fatigue.
- Her findings: A significant lack of butyrate-producing bacteria and low overall diversity.
- Her plan: She deliberately adds cooled potatoes and whole-grain rice to her meals to boost butyrate production. She also adds fermented foods such as kefir and a small glass of sauerkraut juice each day to increase diversity.
Case study B: Tom, 42, wants to lose weight, but his weight has plateaued despite exercising.
- His findings: An unfavorable Firmicutes-to-Bacteroidetes ratio, suggesting overly efficient calorie absorption.
- His plan: Tom focuses on a high-fiber diet rich in vegetables, legumes, and flaxseed to feed the “slim” Bacteroidetes. He cuts back on simple sugars and processed foods, which mainly promote Firmicutes.
These examples show that your mybody-x results don’t just tell you what is wrong, but also how you can make targeted changes.
More than just diet: Your holistic approach
A healthy gut flora needs more than just the right food. Your lifestyle has just as much influence on the well-being of the microbes in your gut. That’s why the following three pillars are an integral part of your personal roadmap:
-
Stress management: Chronic stress can negatively alter the composition of your gut flora and weaken the gut barrier. Techniques such as meditation, yoga, breathing exercises, or regular walks in nature can help lower your stress levels and protect your microbiome.
-
Sleep quality: While you sleep, your entire body regenerates—including your gut. Lack of sleep disrupts not only your hormone balance but also the balance of your gut bacteria. Try to get 7-8 hours per night and establish a regular sleep routine.
-
Regular exercise: Moderate exercise promotes gut motility and the diversity of your gut flora. You don’t have to run a marathon. Regular walks, cycling, or swimming are enough to have a noticeably positive effect.
The personalized recommendations in your mybody-x test take all these aspects into account. They give you a comprehensive, actionable roadmap to actively improve your gut health and overall well-being—step by step and based on your own data.
The future of gut health is personalized
Research into our microbiome never sleeps. What impresses us today as a detailed gut flora analysis may already be standard tomorrow—the pace of development is that rapid. So let’s take a look at where things are headed and why the future of gut health will become much more personal.
The focus is already shifting away from simply counting bacterial strains toward understanding complex networks. It’s no longer just about which bacteria are there, but rather what they actually do and how they work together as a team. The goal is increasingly precise, personalized preventive healthcare.
New building blocks for your microbiome
You probably already know about probiotics (live bacterial cultures) and prebiotics (food for these bacteria). But science is already setting its sights on the next generation of helpers that can give your gut health an even more targeted boost.
These include two particularly exciting concepts:
- Synbiotics: This is the clever combination of pro- and prebiotics in a single product. Think of it this way: You’re not just introducing new, beneficial bacteria, you’re also giving them their favorite food as a housewarming gift. This helps them settle into your gut much more effectively and get to work.
- Postbiotics: The focus here is no longer on the bacteria themselves, but on their valuable metabolic products. These include short-chain fatty acids such as the important butyrate, as well as enzymes and other bioactive substances. They act directly on your intestinal cells, can reduce inflammation, or strengthen the all-important gut barrier.
These new approaches make it possible to address your analysis results much more specifically and close gaps in care more directly.
Expert forecasts already show where things are headed. Personalized microbiome analyses are expected to fundamentally change gut health in Germany soon, moving beyond simply counting bacteria toward a deeper understanding of bacterial networks. In this context, synbiotics and postbiotics are becoming increasingly important because they can work more precisely. Find out more about how these new approaches are changing gut health.
Artificial Intelligence as Your Personal Health Coach
We’re taking personalization to the next level with the help of artificial intelligence (AI). Providers like mybody-x are already pioneers in this field, combining sound science with personal advice. In the future, AI will play an even greater role in interpreting the vast amounts of data from your gut flora analysis.
Imagine intelligent software not only analyzing your microbiome but also linking this data in real time with other information about you. This might include, for example, blood test results, your sleep habits, or your current stress level.
Based on this comprehensive data, an app could give you dynamic, up-to-date recommendations. Perhaps it might suggest a different lunch today than tomorrow because you slept poorly, or recommend a specific relaxation exercise because your stress level is rising. This is no longer science fiction. It’s the next logical step toward giving you even more control over your well-being, based on your body’s unique needs.
Everything else you’d like to know: Your questions about gut flora analysis
Finally, we’d like to answer the questions we’re often asked about a gut flora analysis. You may recognize yourself in one or more of them—our goal is to clear up any remaining doubts and give you complete clarity.
How often should I get a gut flora analysis?
That’s a really good and important question! Your very first analysis is your personal baseline, your “status quo.” It shows you where you stand and where there may be one or two areas of concern in your microbiome.
If you make targeted changes to your diet or lifestyle based on your results, a follow-up analysis after about three to six months is ideal. Your microbiome needs this time to respond to the new changes. The second test then shows you in black and white whether your efforts are paying off and whether the composition of your gut bacteria has improved.
For chronic symptoms or long-term health monitoring, an annual check-up can also be useful to keep track of everything. The mybody-x gut test and the recommendations that come with it can provide you with personalized guidance tailored to your situation and goals.
Does a test like this replace a visit to the doctor?
Absolutely not. A gut flora analysis is an incredibly valuable tool for preventive healthcare and improving your well-being. But it can never replace a medical diagnosis or treatment.
Think of the test as your personal health detective for everyday life. It’s perfect for getting to the bottom of the causes of vague symptoms such as constant bloating, unexplained fatigue, skin problems or stubborn weight issues. It helps you take a proactive approach to your health and better understand your body.
Important: If you have acute, severe or alarming symptoms—such as blood in your stool, intense pain, sudden weight loss or a persistent fever—seeing a doctor is always the first and most important step. The test is a useful supplement, not a replacement.
Do medications affect the results?
Yes, and quite significantly. Certain medications can greatly alter the composition of your gut flora. That’s why collecting the sample at the right time is crucial for getting meaningful results.
Antibiotics in particular have a massive impact. They don’t distinguish between “good” and “bad” bacteria and can seriously disrupt your microbiome. We therefore strongly recommend waiting at least four to six weeks after antibiotic treatment before taking the test. This is the only way to get a representative picture of your “normal” gut health.
Other medications can also affect the results. These include, for example:
- Stomach acid blockers (PPIs): Can change the environment in the upper digestive tract.
- Metformin: Used to treat type 2 diabetes and has known effects on the gut flora.
- Certain laxatives: Regular use can disrupt the balance.
When placing your order, be sure to indicate in the questionnaire which medications or dietary supplements you take regularly. This information is essential for our experts to interpret your results correctly and give you the right recommendations.
