About the department

The Department of Internal Medicine I at the Hospital Gummersbach Oberberg provides treatment of diseases in the fields of gastroenterology (diseases of the digestive tract, liver and pancreas), nephrology and dialysis (kidney diseases) and conservative cardiology (heart diseases), diabetology, infectious diseases and pulmonology. The department is headed by Dr. med. Robert Hoffmann.


The department offers its patients with diabetes services of the consultant diabetologist (according to the program of the German Diabetes Association DDG). After the diagnosis is made, one of the first measures is structured training of the patient. To make it easier for patients to accept and understand the disease, consultant diabetologists provide full basic information about the disease itself and how to live with it. The main task is to restore or maintain the patient's quality of life. The consultant diabetologist is responsible for training and advising patients (and their loved ones) with type I diabetes, type II diabetes, patients with insulin dispensers and other forms of diabetes, such as gestational diabetes.
