What should I eat after surgery?

Published NHS guidance suggests a balanced diet rich in protein, fibre, and fluids to support healing. Protein helps wound repair, fibre prevents constipation from painkillers, and hydration supports recovery.

What foods should I avoid after surgery?

Published guidance suggests avoiding alcohol while on pain medication, limiting processed foods, and being cautious with dairy if experiencing nausea from anaesthetic.

How much water should I drink after surgery?

Published guidance recommends at least 6-8 glasses of water per day after surgery. Adequate hydration supports wound healing and helps prevent constipation.
