Abstract

Overhydration (OH) is a common medical problem found in patients with kidney or heart failure, but still a specific marker has not been found. Clinicians today use bioimpedance spectroscopy (BIS), ultrasound (US) markers of fluid overload or markers of heart and kidney function like NT-pro-BNP, GFR or creatinine levels. New serum markers such as Ca-125, Galectin-3 (Gal-3), Adrenomedullin (AMD) and Urocortin-2 (UCN-2), are being researched with promising results. The need to discover a more precise marker of overhydration is dire mainly because physical examination is extremely imprecise. Signs and symptoms of fluid overload like edema or gradual increase of body mass are not always present, especially in patients with chronic kidney disease. This review paper summarizes actual knowledge of a patient's hydration status estimation focusing especially on kidney diseases.
