The reason why patients with cirrhosis are becoming thinner might be due to the decreased protein synthesis function of the liver after cirrhosis, leading to progressively lesser protein in the body, which results in the patient becoming thinner. It could also be because cirrhosis leads to poor digestion and absorption in patients, thereby reducing their absorption capacity and causing them to lose weight. Under these circumstances, some medications can be used for treatment, such as the infusion of albumin to supplement plasma proteins in the body. It is also important to actively treat the underlying cause of cirrhosis. For example, in the case of alcoholic cirrhosis, active efforts to abstain from alcohol and rehabilitative treatment are necessary. If the cirrhosis is caused by chronic hepatitis B virus infection, antiviral treatment should be administered.
