You can drink carp soup after thyroid cancer surgery. But you can only drink it after the recovery of gastrointestinal function. First of all, crucian carp soup is a high protein food. Before the gastrointestinal function is inhibited due to the anesthetic effect of surgery, drinking carp fish soup before recovery will lead to vomiting and other adverse symptoms. Secondly, in the early postoperative period after thyroid surgery, there is more exudation from the neck area, and therefore more drainage tubes are placed. If you drink too much soup or food with high fat content at this time, it will lead to an increase in the drainage flow, which will affect the healing of the wound, and will not be conducive to the early removal of the drainage tubes. However, if you drink fish and shrimp food such as crucian carp soup after the wound recovery period, you can better replenish the nutrients needed by the body. Therefore, during the recovery period after thyroid surgery, you can eat more high-protein foods and fresh fruits and vegetables, while avoiding spicy and stimulating foods, keeping the wound clean and dry, moderate exercise, avoiding violent coughing, which is conducive to recovery.
