Whether you can eat seaweed after surgery needs to be judged according to the type of surgery taken by the patient and the recovery situation. Generally speaking, for patients with intestinal tumor surgery, when the gastrointestinal function is not fully recovered after surgery, it is generally not recommended to consume kelp to avoid aggravating the burden on the stomach and intestines, and kelp can be consumed moderately after the condition of the patient is fully recovered after surgery. For intracranial surgery patients after taking surgery, if the sanity is not yet completely clear, consuming seaweed may cause food to enter the airway, thus causing a series of uncomfortable reactions, and it is recommended that patients consume seaweed in moderation after their sanity is completely clear after surgery. Thyroid cancer patients are not recommended to eat more kelp after surgery, as kelp contains high iodine and other ingredients, which may lead to goiter, or recurrence of thyroid cancer. For other general surgery patients, after surgery, gastrointestinal function and swallowing function recovery, you can eat kelp in moderation.
