Abnormal liver function is characterized by lack of appetite, general weakness and dizziness, and swelling and pain at the location of the liver. Liver dysfunction is usually caused by drinking too much alcohol or the body’s own immune response. 1. Lack of appetite: loss of appetite, indigestion, not wanting to eat greasy things, and eating less than usual. 2. Generalized weakness and dizziness: Since the liver is the detoxification organ of the human body, when the liver function is not normal, the functioning and detoxification ability of the liver will be slowed down, which affects the detoxification function and prevents harmful substances from being excreted from the body, and people will experience generalized weakness. 3. The location of the liver will be distended and painful: the right upper abdomen will be distended or vaguely painful. The pain increases after strenuous exercise. In patients with abnormal liver function, clinical manifestations may also include abdominal pain, abdominal distension, nausea, vomiting, jaundice, itching of the skin, lightening of the color of stools, deepening of the color of urine, malnutrition, and wasting of body size. If serious discomfort occurs, it is recommended to go to the hospital for diagnosis and treatment, comply with the doctor’s prescription of medication, do not self-medication.
