Innere Medizin is a branch of medicine that focuses on the diagnosis, treatment, and prevention of adult diseases. It encompasses a wide range of health issues, including chronic illnesses like diabetes and hypertension, as well as infectious diseases. Physicians specializing in this field are known as internists and often serve as primary care providers. Internists are trained to manage complex medical conditions and coordinate care among various specialists. They utilize a comprehensive approach, considering the whole patient rather than just specific symptoms. This holistic perspective helps in developing effective treatment plans tailored to individual needs.
