Internal medicine

Internal medicine is a core medical field – in terms of patient care as well as research and teaching. It covers the structure, function and diseases of all the organ systems in our body. It focuses on the prevention, detection, treatment and rehabilitation of disorders or functional failures of the following body systems.

  • Vascular system (angiology)
  • Metabolism and hormones (endocrinology/diabetology)
  • Digestive organs (gastroenterology)
  • Blood and blood-forming organs (hematology/oncology)
  • Heart and circulation (cardiology)
  • Kidney and urinary tract (nephrology)
  • Respiratory organs (pneumology)
  • Bone frame and connective tissue (rheumatology)
Respiratory tract infections

Respiratory tract infections are among the most common illnesses that adults and children contract time and again. Although they are usually harmless, a recurring or persistent respiratory infection sometimes indicates a more serious condition. It is thus advisable to have a doctor check this.

Bronchial asthma

Bronchial asthma can thus become dangerous if left untreated. Given the right treatment, most asthma patients can nevertheless live an almost unrestricted life. We offer both acute and chronic care.


Acute bronchitis is one of the most common respiratory infections. The associated cough, which is initially dry and later mucous, is usually caused by viruses.


The abbreviation COPD stands for “chronic obstructive pulmonary disease”. We offer chronic therapy for this disease.

Atrial fibrillation

Atrial fibrillation is the most common cardiac arrhythmia. Instead of beating regularly, the atria beat too quickly, irregularly and without coordination. Although this does not generally constitute an acute danger, atrial fibrillation can have serious complications if left untreated. We offer comprehensive diagnostics and therapy for atrial fibrillation.

Heart failure

The heart pumps about four to six liters of blood through the body per minute. Unfortunately, however, it does not always work properly: the heart of someone suffering from heart failure has difficulty pumping this amount of blood through the circulatory system. We offer both drug therapy and chronic care at our practice.

Endocrinological diseases
  • Diabetes mellitus type 1 and 2
  • Metabolic syndrome
  • Thyroid diseases
  • Obesity consultation
Gastrointestinal diseases

Functional GI disorders are gut-brain interaction disorders. There is some evidence that these patients suffer from visceral hypersensitivity, a pain perception disorder that makes them perceive as painful sensations (e.g., dilation of intestinal lumen, peristalsis) that other patients do not find disagreeable.

Hepatitis B

Hepatitis B is an infectious liver inflammation caused by the hepatitis B virus. It is transmitted through contact with body fluids of infected persons. This acute inflammation usually heals spontaneously. Vaccination against hepatitis B is recommended.

Hepatitis C

Hepatitis C is an infectious liver inflammation caused by the hepatitis C virus. It is transmitted through the blood of an infected person. Although the disease is usually chronic, it is nevertheless curable. No vaccination is available.

HIV and venereal diseases

Venereal diseases (VD) (for the origin of the word, see venereology) are transmitted exclusively through sexual intercourse.


Syphilis is a sexually transmitted infection. It is transmitted either during unprotected sexual intercourse or from mother to child during birth. It can be cured with antibiotics.
