It is not recommended to take some excessive supplements after bowel cancer surgery. It is generally recommended to take enteral nutrition powder orally, including Nengquanxin, Anxin, Nengquanfu, Beplix, etc., because most of the patients with tumors will be accompanied by malnutrition or nutritional disorders to a greater or lesser extent. Because the consumption of tumor is relatively large, a large part of the body’s nutrition or energy is digested and absorbed by the tumor. After surgery, it is suggested that patients can take enteral nutrition powder in the early stage to restore the peristalsis of gastrointestinal tract and increase the nutrition. After 3-5 days of surgery, when the gas and defecation return to normal, they can also take other enteral nutrition powder, such as Nengquanxin, Beplix, Nengquanli, etc. It is also possible.
