Pineapple juice has been traditionally used as a home remedy to speed up the recovery process after surgery. The theory is that the enzymes in pineapple help to break down scar tissue, which can lead to quicker healing. There is some evidence to support this claim, but it is far from conclusive. A small study published in 2009 found that patients who drank pineapple juice daily for two weeks before and after surgery had less pain and swelling than those who did not drink the juice. However, the study was very small and more research is needed to confirm these results. Overall, drinking pineapple juice after surgery is unlikely to cause any harm and may help with recovery. If you are considering trying it, be sure to check with your doctor first to make sure it is safe for you.
