Increased abdominal circumference caused by liver disease may be due to gastrointestinal flatulence, ascites, intestinal obstruction and so on. 1. Gastrointestinal flatulence: due to liver function damage, patients with liver disease have weaker digestive function, which can not digest the food in the stomach in time, leading to gastrointestinal flatulence and causing the increase of abdominal circumference. 2. Ascites: patients with liver disease due to chronic liver function damage, resulting in decreased albumin synthesis, plasma osmolality decreases, intracellular fluid outflow to form ascites, so the abdominal circumference increases, usually accompanied by nausea, vomiting, feeling of fullness, swelling of the lower limbs, and even dyspnea and other symptoms. Ascites may also be caused by malignant tumors, which are more difficult to subside. 3. Intestinal obstruction: patients with liver disease have gastrointestinal failure in the advanced stage, and the intestinal blood flow is obstructed by intestinal obstruction, which leads to the increase of abdominal circumference, accompanied by the cessation of defecation, cessation of defecation, nausea, vomiting and other symptoms. Liver disease caused by the increase in abdominal circumference, it is recommended that the earliest possible interview, follow the doctor’s instructions for treatment, so as to avoid delaying the condition.
