The most common reason for this are layer filters. Layer Filter, though useful, can multiply very quickly. This also causes the Layer Manager to open up slowly.
So to fix this problem you need to delete all the Layer Filters you don't need. This can take awhile if you have a few thousand filters. AutoLISP to the rescue. Our own Robert Bell wrote a routine just for this problem. See the attached file.

File size is gigantic with nothing in drawing.
Drawing file size is big for no reason
file size does not decrease when objects are purged from dwg

Excessively large DWG files
