In my software, if user edits some content of a document and clicks close icon without saving the changes he made (i.e. without clicking the save icon first), the text of message that I display to the user is as follows:

> 
> Leaving this page will discard unsaved changes.
> 
> 
> 

Should I use ‘the unsaved changes’ instead of simple ‘unsaved changes’? Does this sentence look correct?
