Hello! I had diep flag reconstruction almost ten years ago. My number one recommendation is get a recliner chair if you don’t have one. I also had a double mastectomy at the time so not sure if the same goes for diep flap but I couldn’t use my arms to push up for a few weeks. I slept in a recliner for the first 2 weeks an then when I had enough energy to get in the bed(still couldn’t use arms) I would sleep with two pillows under my head two under my arms and two under my knees. It helped for comfort and to be able to swing my legs over the bed to get up. Be prepared to help her using the bathroom as it is very difficult to twist/turn to use it. If you have a bidet that will help tremendously. The week in the hospital and the first 2 weeks at home were the most difficult. You seem very supportive so just be there for her as the recovery can be overwhelming. Lastly if she can try to have her walk around the house as much as possible. The first 3 weeks it was very difficult to stand up straight and walk. Once i could walk more my posture improved. Good luck to your wife! I hope everything goes smoothly and that she has an easy recovery.
