Kidney Disease and Loss of Appetite
Why do CKD Patients Have a Poor Appetite? Poor appetite is common in patients with chronic kidney disease (CKD), and these symptoms worsen as the disease progresses. The continuous decline of the glomerular filtration rate in CKD patients is associated with a significant reduction in food intake. Around one-third of chronic dialysis patients complain of a fair or poor appetite. And this is directly related to poor patient outcomes. A close association between appetite, malnutrition, and inflammation has been reported in patients undergoing hemodialysis. Leptin inhibits food intake, stimulates energy expenditure, and modulates the activity of nitric oxide synthase (NOS). 28-amino acid peptide ghrelin, synthesized principally in the stomach is responsible for increasing food intake and body weight. Lower levels of acyl ghrelin and obestatin are found in Hemodialysis patients. Increased PTH levels also influence the appetite negatively. Appetite Regulation The factors influencing food int...
