Overview

Obesity in the general population is considered to be a risk factor for the development of cardiovascular diseases and malignant tumour diseases as well as a risk factor for other vascular risk factors (angiometabolic X syndrome, type 2 diabetes, dyslipidaemia, hypertension, hyperuricemia etc.) Last but not least, obesity is also a risk factor for other diseases such as sleep apnoea syndrome, osteoarthritis, gout and non-alcoholic fatty liver disease. However, according to existing studies, among the group of dialysis patients obesity appears to be paradoxically a protective factor in the development of cardiovascular diseases. This phenomenon in dialysis patients is referred to as a “risk factor paradox”. Nevertheless, studies which disprove the protective effect of obesity in dialysis patients exist. This article provides an overview of the obesity’s position in dialysis patients in existing studies.

Key words:
obesity, chronic kidney disease, dialysis patients, „risk factor paradox“
