Patients with advanced liver cancer often experience constipation due to intestinal flora imbalance, reduced bowel motility, and potential ascites accumulation.To address constipation, it is recommended to increase the intake of fresh vegetables and fruits to supplement vitamins and plant fiber. A higher consumption of plant fiber can increase stool volume and maintain regular bowel movements.Additionally, lactulose can be taken as a laxative, as it improves the intestinal pH environment and is particularly effective for advanced liver cancer.Medications that regulate intestinal flora can also be used to adjust the intestinal microecology for better treatment outcomes.
