Liver cirrhosis condition. Many days!

My father had been identified with liver cirrhosis condition 2 years ago in solapur and was under medication and also has psoriasis from last 30 years. 5 months back he belly and legs had got swollen due to discontinuation of liver medication for cirrhosis leading to ascites condition. About 3 liters of fluid were accumulated in the lower abdominal area and about 2.1 liters were removed. He then restarted the medication now there was no issue related to digestion but legs got swollen again. Recently we approached visited a local gastroenterologist in my town they had given diuretics tablets along with some other medicines based on blood report and liver function test report. I just wanted to know how severe the condition and what can be done to improve his health conditions. He is sometimes feeling breathing issues and cough exists from many days
