Sarcopenia is defined by muscle loss and dysfunction. classified into primary secondary types, based on the cause. Primary sarcopenia mainly aging-related sarcopenia, whereas reduced mass strength that accompanies an underlying disease. Given essential role of liver in metabolism, due to nutritional disorders or other factors can frequently occur In 2015, Japan Society Hepatology (JSH) decided establish its own assessment criteria for disease because number patients with expected increase...
