There is a command included in the vimrc_example.vim file distributed with Vim, called :DiffOrig.

This command will open a scratch buffer containing the current on-disk file contents, and diff it with your current unsaved buffer. Then you can see all the changes you've made.

Alternatively, there are also plugins that just let you know what lines have changed, for example, http://www.vim.org/scripts/script.php?script_id=3052 for changes since you started editing, or http://www.vim.org/scripts/script.php?script_id=4487 for changes since the last commit in your version control system.
