Hi thanks for asking question... Noted you have positive hepatitis c Since 20 year...So more chance of cirrhosis. If USG suggest cirrhosis then no need for use of drugs. But if you have chronic hepatitis with active stage then drug can be beneficial to prevent liver complication...HCV RNA load useful in deciding whether it is active stage or not... Meanwhile take low fat diet... Avoid trans fat diet like cheese, butter, meat , baked pestry etc.. Fruits and green leafy veg useful .. Regular exercise done... Avoid alcohol and smoking... Papaiya seed with lemon juice one tsp useful. Cumin seed one tsp with water can be helpful. Take care. Dr.Parth
