Whether patients can eat sea cucumber after thyroid surgery is generally based on the nature of the patient’s thyroid lesion, whether the patient is allergic to sea cucumber, and the recovery of the patient’s gastrointestinal function after surgery. First, if the patient’s thyroid lesion is benign, and the patient’s gastrointestinal function recovers well after surgery, there is no obvious nausea, vomiting, abdominal pain or abdominal distension, and the patient has no allergic reaction to sea cucumber in daily consumption. In this case, the patient can eat sea cucumber after surgery to supplement protein and promote faster wound healing. Second, if the patient’s thyroid gland is malignant, and the patient is prone to allergic reaction to sea cucumber, the patient has more obvious nausea and vomiting symptoms after surgery due to the reaction of anesthesia. At this time, it is not recommended to eat sea cucumber because it is rich in iodine, which may cause the recurrence of tumor and serious complications after eating.
