Can I eat onions after surgery?

Whether onions can be consumed after surgery depends on the type of surgery, the stage of recovery, and individual physical conditions. Onions may be consumed in moderation if gastrointestinal function has recovered well and the surgery was non-irritating; however, they are not recommended for individuals in the recovery phase after gastrointestinal surgery or those with sensitive stomachs. Detailed analysis is as follows:

If the surgery was on the body surface, such as lipoma removal or cesarean section, and gastrointestinal motility has resumed with排气 and defecation post-surgery, onions may be consumed in small quantities after being thoroughly cooked until soft. Onions are rich in vitamin C, dietary fiber, and sulfides, which can provide nutrients, promote wound healing, and help prevent constipation caused by bed rest after surgery. Cooked onions are less irritating, and moderate consumption will not hinder recovery.

If the surgery involved the gastrointestinal tract, mouth, or other parts of the digestive system, the gastrointestinal function may be fragile in the early postoperative phase. The pungent and irritating components of onions can irritate the surgical wound, causing pain, bleeding, or inflammatory reactions, thus delaying the healing process. Additionally, patients with inherently weak gastrointestinal function or existing indigestion may experience worsened bloating or abdominal pain due to the coarse fiber content of onions. In such cases, onion consumption must be strictly avoided.

Post-surgery onion consumption should follow medical advice and be gradually introduced according to the progress of recovery. During cooking, the pungent and irritating portions must be removed, and soft cooking methods such as steaming, boiling, or stewing should be used. Fried or barbecued preparations should be avoided.
