There is no direct relationship between a bad liver and sleep, and sleep conditions cannot be taken as a sign of a bad liver. Sleep quality is not affected when there is mild liver damage, but only when there is pain in the liver area caused by severe liver disease. The liver is the largest digestive gland in the human body and can secrete bile, participate in the decomposition and digestion of food, synthesize albumin, and detoxify drugs. When the liver is not good, the first symptom is digestive discomfort, patients will have an unexplained loss of appetite, anorexia and even nausea, vomiting, etc., and often feel weak, easy to fatigue, always want to sleep and rest. If the liver function is seriously damaged, the liver will become pathologically enlarged, followed by fibrosis, cirrhosis and other lesions. At this stage the patient will suffer from vague pain in the right upper abdomen and abdominal distension which will affect sleep. Liver function further decreases in the late stage of liver badness, and ascites, splenomegaly, jaundice, and gastrointestinal bleeding may occur. If you have not been sleeping well recently, it may be caused by nervousness and anxiety, excessive stress, or disturbances in the rhythm of the biological clock or autonomic nervous function. If self-adjustment fails to restore normal sleep, it is recommended to go to the hospital.
