After colon cancer patients resume anal discharge after surgery, they can eat a liquid diet and transition to normal diet in about two weeks. If there is no special complication, most of the patients will start to resume anal venting three days after colon cancer surgery, then they can eat a small amount of liquid diet, such as water, rice soup, etc., and after that, they can slowly increase the amount. About one week later, if patients have no discomfort, they can eat slightly thicker food, such as fish soup, meat soup, thin rice, etc. Generally, patients can eat normally two weeks after surgery. They need to eat easily digestible food to prevent damage to the intestines of patients and do not eat stimulating food. Patients are advised not to eat spicy and highly oily and pickled food, but need to eat lightly and have a regular diet. In addition, patients should try not to have a full stomach even if they eat normally in the postoperative diet, and it is appropriate to eat less and more meals.
