Your scars will be covered with simple hypoallergenic tape and you will be in an abdominal binder to wear day and night for the first 2 weeks. You can shower from day 1.
For the first few days, as the anaesthesia wears off, you may feel in pain and may need to take over the counter pain relief regularly and at night. Generally patients report that the skin feels tight and they are unable to stand fully straight for the first week. During this time you must take it easy, staying home and only pottering around, so you may need to arrange help with childcare, housework or other duties. Swelling generally is the worst in the first week.
By the end of the first week you can start to venture further afield but listen to your body and do not over do it.
