Thank you for the query.
I have gone through your query and understood your concerns. I am extremely sorry for the loss. You need to be aware of complications after hernia
surgery which includes excessive bleeding after surgery but it is very rare. But when found need an immediate attention and even blood transfusion
is also done. I think this happened due to the age factor and some bleeding disorder
problems. Due to heavy bleeding patient may go to hypovolemic shock
and death. So this is the thing happened and we cant change some situations as no one are responsible for this. Hope this answers your query. Thank you.
