Introduction
Mitochondriopathies are diseases caused by dysfunctions of the mitochondria, the so-called power plants of our cells. These disorders can cause a wide range of symptoms and have a significant impact on quality of life. In this article, we will explain the basics of mitochondriopathies, their causes, symptoms, diagnosis and, in particular, acquired mitochondriopathies and possible treatment approaches.
What are mitochondria?
Mitochondria are small structures in our cells that play a crucial role in energy production. They convert nutrients from our food and inhaled oxygen into adenosine triphosphate (ATP), which serves as an energy carrier for many cellular processes and thus provides the necessary energy. Without sufficient ATP, no cell can function properly. Particularly energy-intensive cells such as heart muscle cells or nerve cells have a particularly large number of mitochondria.
What are mitochondriopathies?
Mitochondriopathies, also known as mitochondrial diseases, refer to functional disorders of the mitochondria. These can be either congenital or acquired. While congenital mitochondriopathies are genetically determined and often show symptoms in childhood, acquired mitochondriopathies develop in the course of life due to various external influences and can affect anyone. Acquired mitochondriopathies can manifest themselves in adulthood.

Causes of acquired mitochondriopathies
Acquired mitochondriopathies are caused by damage to the mitochondria, which can be attributed to various factors:
- Oxidative & nitrosative stress: environmental toxins, smoking, alcohol, certain medications or chronic infections produce harmful free radicals in the cells. These can damage the mitochondria and impair their function.
- Unhealthy diet: A diet rich in sugar and unhealthy fats can put a strain on the mitochondria. A lack of important nutrients such as vitamins and minerals can also weaken the mitochondria.
- Chronic stress: Mental and physical stress can increase the production of stress hormones, which in turn can damage the mitochondria.
- Pollutants & environmental toxins: Pesticides, heavy metals and other environmental toxins can directly damage the mitochondria.
- Lack of exercise: Physical inactivity means that the mitochondria are less active and can break down. At the same time, the body becomes more susceptible to oxidative damage.
An example of a specific syndrome associated with mitochondrial dysfunction is Kearns-Sayre syndrome (KSS).
Symptoms of acquired mitochondriopathies & muscle weakness
The symptoms of acquired mitochondriopathies are diverse and affect different organ systems and can occur as early as childhood and adolescence.³ Typical symptoms are
- Chronic tiredness & fatigue: a general feeling of exhaustion that does not improve with sleep.
- Muscle weakness & pain: Mitochondriopathies primarily affect the muscles, leading to weakness, fatigue and other movement disorders. Those affected may experience muscle pain, cramps and weakness, especially after physical activity.
- Cognitive problems: Memory problems, difficulty concentrating and mental fatigue.
- Heart problems: Cardiac arrhythmias and decreased cardiac output may occur.
- Digestive problems: These include bloating, constipation and abdominal pain.
- Neurological symptoms: headaches, migraines and, in severe cases, seizures.
Diagnosis of mitochondriopathies
Dr. Müller emphasizes the importance of a detailed medical history and physical examination in the diagnosis of mitochondriopathies. The symptoms of these diseases can be very diverse and include muscle weakness, exercise intolerance, retinal degeneration and neurological disorders. As the symptoms can be very unspecific, it is important to rule out other possible causes. The following diagnostic measures can help:
- Blood tests: determination of lactate and pyruvate² levels in the blood. An elevated ratio of these two substances may indicate mitochondrial dysfunction.
- Urinalysis: Determination of metabolic products that may indicate impaired mitochondrial function.
- Muscle biopsy: Removal and examination of a small muscle sample to examine the mitochondria directly.
- Imaging procedures: MRI and other imaging techniques can help identify structural changes in affected organs.
- Genetic testing: Although more commonly used for congenital forms, genetic testing can also provide clues to acquired mitochondriopathies, especially if a genetic predisposition is suspected.
Regular exercise such as yoga supports our mitochondria in their function.
Therapeutic approaches for acquired mitochondriopathies
Dr. Müller recommends various therapeutic approaches to support mitochondrial function. Since there is no cure for mitochondriopathies, therapy focuses on alleviating symptoms and supporting mitochondrial function. Mitochondria, as important cell organelles, play a central role in therapeutic approaches. Here are some of the most important approaches:
Change of diet
The importance of a healthy diet to support mitochondrial function is essential. The following nutrients are particularly important:
- Antioxidants: these neutralize free radicals and reduce oxidative stress. Important antioxidants are vitamin C, vitamin E and alpha-lipoic acid.
- B-group vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin) and B12 (cobalamin) are particularly important for energy metabolism.
- Coenzyme Q10: An important component of the mitochondrial respiratory chain, which supports energy production.
- L-carnitine: Supports the transport of fatty acids into the mitochondria, where they are used to generate energy.
- Omega-3 fatty acids: These have anti-inflammatory properties and support the cell membranes.
A balanced diet from an early age is crucial to support mitochondrial function and promote long-term health.
Lifestyle changes
- Stress reduction: Techniques such as yoga, meditation and breathing exercises are recommended to reduce stress and support the mitochondria.
- Regular exercise: Moderate physical activity can increase the number and efficiency of mitochondria. This includes endurance training such as jogging, swimming or cycling.
- Avoiding toxins: Reducing exposure to environmental toxins, e.g. by not smoking, eating organic food and using natural cleaning products.
It is important to establish healthy habits from an early age to promote long-term mitochondrial health.
Meditation counteracts stress and effectively supports our mitochondria in this way.
Supplementation & medicinal approaches
- Antioxidants: The regular intake of antioxidant supplements is particularly suitable for reducing oxidative stress.
- Cofactors: Supplementation of coenzyme Q10, L-carnitine and other important micronutrients.
- Specific medications: In some cases, medications such as idebenone may be helpful for certain mitochondrial diseases. These approaches can help treat mitochondrial diseases by alleviating the multisystemic manifestations, particularly in the muscles and nervous system.
Prevention of acquired mitochondriopathies
Prevention plays a crucial role in avoiding mitochondriopathies. Here are some important measures:
- Eating a healthy diet: a balanced diet rich in fresh fruits, vegetables, whole grains and healthy fats can help maintain mitochondrial health.
- Avoidance of pollutants: Reducing exposure to environmental toxins and chemicals.
- Regular exercise: Physical activity can improve the number and efficiency of mitochondria.
- Stress management: Stress management techniques can help reduce stress on the mitochondria.
- Adequate sleep: Good sleep is important for mitochondrial regeneration and function.
These measures can reduce the risk of mitochondriopathy, including various syndromes such as Kearns Syre Syndrome⁵ and MERRF syndrome.
Case studies & clinical studies on Kearns Sayre Syndrome (KSS)
Dr. Müller conducted a clinical study that showed that patients with chronic fatigue syndrome (CFS) experienced significant improvements in their symptoms after a comprehensive mitochondrial therapy. This therapy included a combination of dietary changes, supplementation and moderate exercise. In addition, these therapies were found to have positive effects on patients' energy levels.
Another study investigated the effect of coenzyme Q10 in patients with heart failure and found that supplementation led to an improvement in heart function and quality of life.
Outlook and future research
Mitochondriopathy research is a rapidly growing field and new approaches and treatments are constantly being developed. Future therapies could include gene therapy, stem cell therapy and other innovative approaches.
Conclusion
Acquired mitochondriopathies are complex and multifaceted diseases that require careful diagnosis and individually tailored treatment. Through a combination of a healthy diet, lifestyle changes, supplementation and the avoidance of harmful substances, sufferers can alleviate their symptoms and significantly improve their quality of life. Ongoing research in this area gives hope that even better diagnostic and therapeutic options will be developed in the future. It is particularly important to monitor hormonal imbalances, such as diabetes mellitus, in patients with mitochondriopathies.
