Liver disease more serious period is more like sleepy. As the severity of liver disease varies from person to person, it is recommended to go to the hospital for further examination to clarify the cause of the disease and treat the cause. The main functions of the liver in the human body are detoxification, metabolism and transformation. When people’s liver is damaged, especially with severe cirrhosis, the liver is unable to metabolize proteins, sugar and other substances that provide energy for the body, resulting in drowsiness, fatigue and other symptoms due to lack of energy. When people have a bad liver, they should avoid bad habits such as staying up late at night and drinking too much alcohol, and should eat a light and digestible diet. People with serious liver damage are recommended to take liver-protecting medication (e.g. liver-protecting drugs such as glycyrrhizin) under the guidance of a doctor.
