Hello dear
Warm welcome to Healthcaremagic.com
I have evaluated your query in details .
* There are many types of
hernia possible in a male as inguinal ,
epigastric , lumbar , umbilical , incisional hernia if past surgery ,
hiatus hernia so the cause depends upon the type in particular .
* If I assume that you are asking for most common one which is
inguinal hernia then :
Causes - increased pressure in abdominal wall as excess straining ,
severe
constipation , urinary retentions , others .
- excess weight lifting
- chronic
cough Side effects of surgery which may or may not include following :
-
Anesthesia complications
- Surgery related - infection - recurrence - others .
Healing time after surgery is 10 days for wound , 3 months for internal
mesh and healing .
Wishing him fine recovery .
Welcome for any further guidance .
