PRIVATE PRACTICE FOR MODERN GENERAL MEDICINE AND PREVENTIVE HEALTH
Modern private healthcare with personalised medical guidance.
Prevention, Nutritional Medicine, Sports Medicine, advanced non-surgical treatments for knee osteoarthritis including Arthrosamid®, and Longevity Medicine — personalised, structured and physician-led.
For private patients and self-paying patients

Specialties
Areas of Medical Expertise of our Practice.
Our practice focuses on preventive health assessments and check-ups, Nutritional Medicine, Sports Medicine with a dedicated osteoarthritis clinic, and Longevity Medicine.
As part of our osteoarthritis care, particular emphasis is placed on the treatment of knee osteoarthritis, including the use of Arthrosamid®, an injectable hydrogel implant designed to provide long-lasting pain relief without surgery and to help improve mobility and quality of life.
Check-ups & Preventive Medicine
Early detection and prevention are the foundation of long-term health.
Health is individual – and so is prevention. Age, sex, family history, professional circumstances and lifestyle all influence personal health risks in different ways. As part of our check-up and preventive medicine programme, we identify potential risk factors at an early stage and develop a personalised prevention strategy tailored to your individual needs. This includes modern diagnostic assessments, targeted laboratory testing, and evidence-based recommendations regarding nutrition, physical activity and lifestyle.

Nutritional Medicine & Weight Management
Sustainable weight loss is about more than simply reducing calorie intake.
We provide personalised, evidence-based medical support for dietary change, metabolic health optimisation and long-term weight management through a comprehensive approach that combines nutrition, physical activity and modern fasting strategies. A particular focus of our practice is the safe and appropriate use of modern weight-loss medications such as Ozempic® and Wegovy® (GLP-1 receptor agonists).

Sports Medicine & Osteoarthritis Care
Preserving mobility, reducing pain and improving quality of life.
Physical activity is an essential part of a healthy and active life, regardless of age or fitness level. I support both recreational and competitive athletes, as well as individuals who wish to maintain their mobility, physical performance and quality of life throughout adulthood and later life.

Men's Medicine
Health, vitality and well-being at every stage of life.
Physical health, vitality and sexual well-being are important aspects of quality of life for many men. They influence not only sexual health, but also confidence, energy levels, performance and overall well-being.

Longevity Medicine
Healthy ageing is about more than simply avoiding disease.
It is never too early – and never too late – to focus on longevity. For me, Longevity Medicine represents a comprehensive medical approach aimed not only at extending lifespan, but above all at preserving physical and cognitive health for as long as possible.

Telemedicine
Modern medical care — even between practice visits.
Many health concerns can now be managed efficiently, discreetly and personally through telemedicine, including the discussion of test results, follow-up consultations, Nutritional Medicine, GLP-1 therapy for weight management, Men's Medicine, preventive health consultations and Sports Medicine.

About me
Medicine guided by experience and personalised care.
Hernán Leonardo Aceval Munoz, I studied Medicine and Psychology at the University of Bonn and am a board-certified specialist in General Medicine, Emergency Physician, Aeromedical Physician and Psychologist.
After many years working in hospital-based surgical care, I now practise primarily in outpatient General Medicine. In parallel, I continue to work as an Emergency Physician and Aeromedical Physician, providing national and international patient transport and medical care, including assignments in crisis regions. My particular areas of interest include Nutritional Medicine, Sports Medicine, Men's Medicine and Longevity Medicine. As both a physician and psychologist, I regard physical and mental health as inseparably linked. Individualised care, personal attention and a partnership-based doctor–patient relationship are at the heart of my medical practice.
The decision to establish a private medical practice was a conscious one. It gives me the professional independence to focus diagnostics, treatment and preventive care entirely on the individual needs of my patients. Without rigid administrative constraints or unnecessary time pressure, I am able to devote the time that careful, modern medicine requires. I welcome both privately insured patients and self-paying patients. It is important to me that access to personalised medical care should not depend solely on insurance status or financial considerations. For this reason, I work together with my patients to find solutions that are both medically appropriate and individually sustainable.
