Comprehensive GI diagnostic

Microbiome Assessment and Dietary Behavior Correction
The human microbiome is a complex ecosystem of trillions of bacteria, viruses, and fungi living inside us. The gut microbiome is particularly important, as it regulates nutrient absorption, immune system function, and even mood. When the balance of this system is disrupted, symptoms such as bloating, discomfort, fatigue, and weight problems appear, along with an increased risk of chronic intestinal inflammation.
The human intestinal microbiota and bacterial microbiome play a crucial role in maintaining health. Disorders in the small intestine are also significant and affect overall well-being, as this is where active nutrient absorption occurs.
To help you address disorders as quickly and effectively as possible and restore your microbiome structure, we have created a program for comprehensive non-invasive intestinal assessment.
Who Is It For
The diagnostic plan is designed for adults and adolescents with digestive, metabolic, and eating disorders, as well as for patients with chronic inflammatory diseases and autoimmune conditions. It is suitable if you experience:
- Frequent bloating, increased gas, constipation, or diarrhea
- Unexplained fatigue, skin rashes, anxiety, or weight fluctuations
- Suspected sensitivity to certain foods (gluten, lactose, FODMAP foods containing fermentable carbohydrates)
- Diagnosed conditions such as celiac disease, Crohn's disease, autoimmune thyroiditis, or ulcerative colitis
- Eating disorders, sugar cravings, or overeating
The examination helps distinguish between organic diseases (such as celiac disease, inflammatory processes, or enzyme deficiency) and functional disorders like irritable bowel syndrome. This is essential for selecting the appropriate treatment strategy and prevention measures.
The main goal is to identify the causes of discomfort, restore a healthy gut microbiome, improve well-being, and normalize digestion.
When we understand the state of your intestinal microflora, it becomes much easier to assess how food composition and environmental factors affect your body, and then select effective treatment.
What Is Included in the Examination
This is a non-invasive comprehensive examination that includes ultrasound, blood and stool tests, as well as breath testing. This diagnostic approach allows us to assess intestinal health without colonoscopy and determine whether further instrumental examination is needed.
Laboratory Diagnostics
- Gut microbiome analysis (DNA test) to assess bacterial diversity and balance (stool)
- Determination of inflammatory biomarkers, enzyme activity, and metabolic markers (blood, stool)
- Liver function tests, immunoglobulin levels, celiac disease screening (blood), SIBO breath test for diagnosing small intestinal bacterial overgrowth
This is an evidence-based approach that identifies the root cause of symptoms rather than simply eliminating foods from your diet.
Instrumental Studies
- Abdominal ultrasound and liver elastography (as indicated)
Consultations
Initial appointment with a gastroenterologist-dietitian — analysis of symptoms, eating habits, and lifestyle factors.
Follow-up appointment — after laboratory and instrumental studies: discussion of test results, development of a personalized plan with recommendations for nutrition, treatment, and gut microbiome restoration.

How the Examination Proceeds
All examinations can be completed in two visits.
First visit: consultation, ultrasound, blood and stool sample collection.
Follow-up visit: review of results, selection of probiotics and nutraceuticals, recommendations for nutrition and stress management.
What's Important to Know About the Microbiome
The gut microbiome and its structure are directly linked to many bodily functions. In a healthy state, it consists of numerous bacterial communities, particularly active in the colon, small intestine, and oral cavity — where microorganisms help digest and absorb food while protecting the mucous membranes.
In healthy individuals, this balance is maintained naturally, but stress, poor nutrition, or antibiotic use can disrupt human microbiome function.
Simply put, when the microbiome becomes imbalanced, beneficial bacteria decrease while potentially problematic ones increase.
Microbiota imbalance can also affect tolerance to specific foods — for example, dairy or gluten-containing products — which is related not to allergy, but to changes in enzyme activity and intestinal flora composition.
Microbiome restoration is critically important for health, not only for normalizing digestion and metabolism, but also for preventing chronic diseases, maintaining immune defense, and supporting stable emotional well-being.

Who Conducts Microbiome Research at Kandinsky Clinic
At our clinic, appointments are conducted by gastroenterologist and dietitian Elena Voronina, as well as gastroenterologist Alexander Khvoshchev. Both are specialists with extensive experience treating patients with gastrointestinal diseases and metabolic disorders.
Our doctors will professionally assess your microbiome structure, interpret research results, and develop personalized nutrition and treatment plans aimed at restoring microbiota balance.
