Abdominal distension in hepatocellular carcinoma may be caused by ascites, or it may be caused by slow peristalsis of the gastrointestinal tract, which leads to gas accumulation in the intestinal tract. If the bloating is caused by ascites, oral diuretics such as furosemide and spironolactone can reduce the tissue edema and the ascites in the abdominal cavity, which can effectively relieve the bloating. At the same time, hepatocellular carcinoma may be combined with hypoproteinemia, so if necessary, intravenous albumin should be used to improve the patient’s hypoproteinemia, which can also effectively relieve abdominal distension. If liver cancer is late, it may lead to slow down of gastrointestinal peristalsis and patients may have abdominal distension, especially if there is intestinal obstruction due to tumor metastasis in the abdominal cavity, abdominal distension will be more obvious.
