How long does it take to recover from large polyp removal?

You shouldn't drive for 24 hours following a polypectomy. Recovery is generally quick. Minor side effects such as gassiness, bloating, and cramps usually resolve within 24 hours. With a more involved procedure, a full recovery can take up to two weeks.
