About the department

The department of internal medicine (gastroenterology, hepatology, cardiology, pulmonology) at Nordwest Hospital Frankfurt am Main serves all patients with therapeutic diseases of the gastrointestinal tract, liver, lungs and cardiovascular system. Doctors pay special attention to patients with acute conditions - the department has all the conditions for the round-the-clock provision of all types of medical care. Thanks to the close integration of the Internal Intensive Care Unit, Monitoring Unit, Ventilation Unit and Chest Pain Unit, the department guarantees the optimal quality of care for all current acute diseases and internal medicine emergencies. The medical team of doctors is on duty in the department around the clock. For diagnostics, the medical team has modern equipment for ultrasound examinations, endoscopic examinations, examination of lung functions and catheter diagnostics of the heart. In total, seven inpatient departments serve up to 5,000 patients per year.

Experienced doctors of the department treat the full range of diseases of internal organs, including inflammatory, autoimmune, allergic and degenerative diseases, as well as benign and malignant tumours. The therapeutic possibilities of the department are pretty extensive - from conservative medical therapy and endoscopic treatment procedures to catheter-assisted therapeutic approaches. The department's medical staff creates a pleasant and friendly atmosphere so that the patient feels as comfortable as possible.
