Sea cucumber can be eaten after prostate cancer surgery, but only if the patient has no seafood allergy. As long as the patient is able to eat sea cucumber, he/she can eat sea cucumber normally after the surgery without any effect. Sea cucumber is rich in many kinds of nutrients, which can improve local immunity, body resistance and supplement certain nutrition after surgery. Therefore, after prostate surgery, it can be consumed appropriately and will not cause any side effects such as local wound infection or tumor recurrence. However, if the patient has allergy or hyperuricemia, he should not eat sea cucumber, otherwise, after using sea cucumber for a long time and in large quantities, the level of uric acid in the body may increase or there may be local allergy, which may be manifested as itching or local redness and swelling. Besides sea cucumber, other types of nutrients can also be consumed appropriately, such as small amount of protein, sugar, carbohydrates and fats, etc., all of which are helpful for recovery after surgery. However, it is important not to take too much of these nutrients and to go to the hospital regularly for blood, biochemistry and electrolyte tests to assess the post-surgery recovery.
