Hello dear, thanks for your question. I suggest you to check with your surgeon to be sure, but exercise for bariatric surgery patients can generally begin within three to six weeks following surgery.
But you should begin walking for 20 to 30 minutes per day as soon as you get home. Start with a slow pace and gradually increase the speed at which you walk as your endurance improves.
By the time you reach six weeks post-op, you should be able to complete three 10 minute walks per day while walking at a relatively quick pace. After week six, it may be time to begin a more intensive exercise routine including strengthening, flexibility and more aggressive endurance execrases.Good luck.
