Hi Dear, Welcome to Health Care Magic Team. Understanding your concern about health of your dad. Liver enlargement of your dad as per your query is a case of fatty liver which occurs due to excess intake of alcohol. There are other factors which cause and exagerrate this condition but excessive alcohol is the causative agent here. It will cause cirrhosis of liver. Obesity exagerrates this condition. I would suggest you to advice your dad to stop intake of alcohol completely. Drugs such as Adasera is effective for liver functioning in case of cirrhotic liver. Excercise should be done on daily basis to avoid obesity. Avoid diet rich in unsaturated fatty acids. I would suggest you to go to gastroenterologist with your dad. Get fibrooptic scan done to detect the amount of cirrhosis. Then start with the proper prescribed treatment like treatment for alcohol dependency and beta blocker for portal hypertension. I hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
