My 72 year old father had open surgery to repair an anerism on his
Aorta 8 days ago. Initially he seemed to do well, but now seems to have
gone back a little - he is displaying the following symptoms:-

1. Constipation - he had to have enema to clear his bowels - 7 days
after surgery
2. Lack of Appetite
3.Nauesa and Sickness
4. Exhaustion.

We were warned that he would feel ill for a while after this surgery -
but can anyone advise:-

are the above symptoms typical or to be expected ?

Do any of them indicate surgery has not been succesful ?
