 Hi, I'm Dr. Olyth Selvan, Consulant Haptologist and Chairman Division of Liver Transplantation, Manipal Hospitals, Bangalore. The liver is the most important organ in the body which looks after our metabolic functions. It's an important organ to prevent infections. It's the organ which detoxifies all the toxins in our body and keeps it healthy. So there are things which we need to do to keep our liver healthy. The first and foremost thing is to not take things which would be harmful to the liver. The foremost of that will be avoiding alcohol. Second would be to maintain a healthy life in way of maintaining your weight which should be proportional to your height, which can be again through good diet and regular exercise. In our country, hepatitis B and hepatitis C are very common. So if possible, you have to check yourself to make sure you don't have these infections. And the fourth important thing is to avoid toxic substances to the liver like herbal medications and over-the-counter medications which are taken without the prescription of a doctor.
