Chronic fatigue, HPU and mitochondria – Dr. Karsten Ostermann's perspective
Chronic fatigue is often a manifestation of measurable biological disorders such as HPU, mitochondrial dysfunction, chronic infections, and environmental stressors – not merely a psychological problem. Dr. Karsten Ostermann has been systematically integrating these factors into diagnostics and therapy for years and, as an expert, also shapes this approach at EVER.

Chronic fatigue, unexplained pain, irritability, brain fog, and exercise intolerance are no longer fringe phenomena – they are among the most common yet least understood health problems of our time. Although countless people live with them, the causes often remain undiscovered.
This is precisely where integrative and functional medicine in. And hardly anyone in the German-speaking world combines these disciplines as comprehensively as Dr. Karsten Ostermann, a specialist in general medicine and in mitochondrial medicine, HPU, chronic infections, and metal toxicology. His decades of experience demonstrate that energy deficiency is not a mystery – but a biological signal that can be deciphered.
Why so many people struggle with a lack of energy today – and why it's not purely a psychological issue
Fatigue is not simply fatigue. On a biochemical level, it often means that the mitochondria – our cellular power plants – are overloaded or blocked.
Possible causes include:
- chronic infections such as Lyme disease
- Environmental toxins and metal contamination
- Metabolic disorders such as HPU
- persistent oxidative stress
- a dysregulated immune system
The symptoms appear nonspecific, but the mechanisms are clearly measurable.
Practical experience – including Ostermann's work – shows that many of these factors occur together and reinforce each other.
HPU: An overlooked pattern in energy deficiency
HPU (hemopyrrollactamuria) is a metabolic and regulatory disorder that:
- depletes micronutrients
- weakens detoxification,
- the stress axis is destabilized,
- and hinders energy production.
The fact that it receives little attention in conventional medicine means that many sufferers remain in the dark for years.
In functional medicine, HPU is considered a keyto understanding chronic fatigue. Dr. Ostermann is among the most experienced physicians who can differentiate and treat this condition.
Lyme disease & chronic infections: When the immune system never gets a chance to rest
Chronic infections are one of the biggest stressors for mitochondria and the nervous system.
They produce:
- persistent inflammatory signals
- nitrosative stress
- mitochondrial blockages
- cognitive impairments
As the long-standing third chairman of the German Lyme Disease Society, Ostermann works at the forefront of diagnostics, education, and therapy for chronic infections. His perspective brings rare clarity to a complex field.
Heavy metal exposure and detoxification: An often overlooked component.
Environmental medicine remains underrepresented in many treatment pathways. Yet heavy metals in particular – mercury, lead, cadmium – can:
- enzymes inhibit
- irritate the nervous system
- Slowing down energy production
- blocking detoxification processes
As Vice President of the German Society for Clinical Metal Toxicology (KMT), Ostermann is one of the few physicians who use chelation therapy in a differentiated, safe, and evidence-based manner. He understands both the mechanisms and the pitfalls.
What makes Dr. Ostermann's approach special
What is special about his medical thinking is not a single method – but the ability to recognize connectionswhere others see separate areas.
His approach combines:
- functional diagnostics
- Mitochondrial medicine
- Naturopathy & Regulatory Medicine
- Environmental medicine
- Orthomolecular therapy
- Traditional Chinese Medicine (TCM) and acupuncture
The goal is clear: regulation instead of symptom suppression. Anyone who understands how energy is generated in the body also understands why it can be lost.
Why we value him so highly as a Founding Expert at EVER
EVER collaborates with experts who not only master a medical field but also shape it. In Dr. Karsten Ostermann's case, there are three reasons that make him an indispensable part of the Founding Experts:
1. Deep specialization in the biology of exhaustion
HPU, Lyme disease, metal toxicology, and mitochondrial dysfunction form the core components of many chronic diseases. This expertise is rare – and highly relevant for prevention and digital diagnostics.
2. Ability to think systemically about complex cases
His extensive experience with multisystem diseases makes him one of the voices that recognizes patterns before others even know what they are looking for.
3. Bridge between research, clinical practice and the digital future
Ostermann belongs to that generation of doctors who are ready to make knowledge scalable – so that diagnostics and prevention become more precise, faster and accessible to more people.
His work supports EVER in developing protocols and digital processes that don't just superficially optimize, but truly regulate. He brings knowledge to the platform that many patients would otherwise never have access to.
