When we talk about gut health today, we think of microbiome research, probiotics, and leaky gut. That is correct and important. But it has a predecessor that was remarkably ahead of its time.
Franz Xaver Mayr, an Austrian physician (1875–1965), developed a medical system that placed the gut at the center of health assessment. Not as an isolated organ, but as a reflection of the body's overall condition and as the starting point for therapeutic intervention.
What was clinical intuition back then is evidence-based medicine today. At the Buff Medical Resort, F.X. Mayr medicine is a core component of our prevention programs.
What F.X. Mayr medicine is – and what it is not
F.X. Mayr medicine is not a fasting program. It is not a detox trend. It is not a diet. It is a holistic medical diagnostic and therapeutic concept aimed at promoting gut health and regenerating the body for the long term. It is based on four pillars – the four S's: sparing, cleansing, schooling, and substitution.
Sparing means providing relief and regeneration for the entire organism. This includes sufficient rest, restorative sleep, relaxation, and targeted relief for the digestive system.
Cleansing supports the body's natural elimination and detoxification processes. At the Buff Medical Resort, saline cleansing is typically performed using Epsom salt or magnesium citrate. Additionally, manual abdominal treatments performed by our physicians promote bowel function and support physiological cleansing processes.
Schooling aims to help you relearn healthy eating habits. The focus is on mindful eating, thorough chewing, eating slowly, recognizing your natural feeling of satiety, and ensuring adequate fluid intake. Our Mayr roll serves as a chewing trainer: ideally, each bite should be chewed 30 to 40 times. After all, digestion begins in the mouth. Thorough chewing optimally prepares food and relieves the digestive organs.
Substitution is used to specifically address deficiencies in vitamins, minerals, and trace elements. This is based on individual diagnostics, such as blood tests, genetic analyses, or organic acid tests. This allows nutrients to be supplemented as needed, optimally supporting the body's regeneration.
What modern research confirms
The core principles of Mayr medicine now have strong scientific support:
· The gut microbiome regulates the immune system, mood, metabolism, and systemic inflammation [1]. Changes in the gut microbiome are observed in a variety of chronic diseases. We also see changes following antibiotic use that can persist for several months.
· The gut-brain axis facilitates bidirectional signaling between the digestive system and the brain. What happens in the gut influences cognition, mood, and stress processing [2].
· Intestinal permeability (leaky gut) allows bacterial metabolites to enter the bloodstream, triggering systemic inflammatory processes.
· Calorie restriction and cleansing diets stimulate autophagy and mitochondrial biogenesis, two of the most important longevity mechanisms.

F.X. Mayr Medicine at Buff Medical Resort
At Buff Medical Resort, we combine classic Mayr diagnostics and therapy with modern laboratory diagnostics: microbiome analysis, intestinal permeability markers, metabolic profiling, organic acids, genetic testing, and inflammatory parameters complement the initial clinical examination.
The result is a precise picture of your gut health, allowing for individually tailored therapeutic interventions. Not everyone needs the same thing. Depending on the underlying cause, different therapeutic approaches are required. For example, small intestinal bacterial overgrowth (SIBO) requires a different approach than impaired intestinal motility.
In one of the most beautiful locations on Lake Constance, we combine the proven principles of F.X. Mayr medicine with modern diagnostics. This creates the foundation for an individually tailored therapy that specifically supports gut health and strengthens the function of the entire organism.
FAQ
What is a Mayr cure?
A Mayr cure is not a fasting program, but a medical therapy concept developed by Franz Xaver Mayr. It includes intestinal diagnostics, a therapeutic relief diet, and the rehabilitation of digestive function. The goal is not weight loss, but the regeneration of the intestine as a central organ of health.
What distinguishes F.X. Mayr Medicine from a standard gut cleanse?
F.X. Mayr Medicine is a comprehensive medical system with its own diagnostic methodology, not just a nutritional intervention. Clinical Mayr diagnostics assess the gut through palpation, medical history, and clinical signs. At the Buff Medical Resort, this is combined with modern laboratory diagnostics, including microbiome analysis and inflammatory markers.
Who benefits from F.X. Mayr medicine?
People with chronic digestive issues, fatigue, food intolerances, skin problems, or vague symptoms without a clear diagnosis. Even those without specific complaints who wish to proactively optimize their health can benefit from comprehensive diagnostics and therapy based on the principles of F.X. Mayr medicine.
What does the gut have to do with longevity?
The gut microbiome influences the immune system, inflammation levels, metabolism, and the gut-brain axis. A healthy microbiome is associated with a reduced risk of chronic disease and slower biological aging. Gut health is therefore a central factor in any serious longevity strategy.
