Mandatory medical device diagnostics.
- Electrical impedance analysis (measurement of body compartments/body composition) – for determination of body fat, extracellular body mass (blood and tissue fluid), body cell mass (muscle and organ mass), and total body water including body mass index (BMI, body mass index) and waist-to-hip ratio (THV); very valid measurement method (part of the guidelines of the German Diabetes Society and the German Obesity Society).
Optional medical device diagnostics – depending on the results of the history, physical examination and laboratory diagnostics – for differential diagnostic clarification.
- Cardiovascular check included
- Exercise ECG (electrocardiogram during exercise, that is, under physical activity/exercise ergometry).
- Intima-media thickness (synonyms: IMD; intima-media-thickness – IMT) of the common carotid artery bilaterally [determinant of subclinical atherosclerosis].
- Transcranial Doppler sonography (ultrasound examination through the intact skull for orienting control of cerebral (“concerning the brain”) blood flow; brain ultrasound) – Doppler sonographic evidence of stenoses, plaques, or intima-media-thickness (IMT; IMD) of the carotid arteries (carotid arteries) signify increased risk for myocardial infarction (heart attack)/apoplexy (stroke)
- Echocardiography (echo; heart ultrasound) – if secondary diseases of obesity in the cardiovascular system such as coronary heart disease (CHD) are suspected.
- Sleep apnea screening
- Abdominal ultrasonography (ultrasound examination of the abdominal organs) – if secondary disease of obesity such as steatosis hepatis (fatty liver) is suspected.
- Spirometry (basic examination in the context of pulmonary function diagnostics) – if pulmonary dysfunction is suspected.
