it's major surgery and everyone reacts differently.
The main issue as I had wife at home is to help. Night bag , positioning , emptying . Keep everything spotless.
Don't over fret about showers and bathing too much. Incisions may be stapled, stitched. Mine were all glued and healed fine. Keep dry.
The key is slowly and steady. NO heavy lifting. Don't over do it.
He will probably be emotionally, physically and mentally drained.
Just keep an eye 're. being off food or not himself. not getting up and about at all ie red flag signs that something isn't going to plan. Keep fluid intake high and regular. ie output should be light white wine and clear quite soon.
regular bowel function could take a week or 2. Depends on his reaction to meds etc.
Is he employed ?
In a nutshell. listen and observe.
I know it took me a couple of weeks to walk at a good pace. getting in out of a low seated car was uncomfortable.
everyone is different. I had major fluid leakage one night from an incision. I was told this does happen ! I knew or was told nothing about it.
Hope this helps.
