Lack of energy in patients with hepatic ascites may be related to decreased digestive ability, electrolyte disorders, hepatic encephalopathy, and so on. 1. Decreased digestive ability: Decreased digestive ability of patients with hepatic ascites may lead to insufficient energy intake, which in turn may lead to fatigue. 2. Electrolyte disorders: when diuretic treatment is carried out for hepatic ascites, we should be alert to the possibility of electrolyte disorders, which may cause fatigue if hyponatremia or hypokalemia occurs. 3. Hepatic encephalopathy: If complicated by hepatic encephalopathy, it can lead to metabolic disorders in the human body, and it is easy to have loss of appetite, weakness, etc., which will cause malnutrition. If the body is unable to absorb nutrients, weight loss and emaciation may occur. If the symptoms persist, it is recommended to consult a doctor to determine the cause of the disease and to treat the disease under the guidance of the doctor.
