Multiple sources have confirmed to Entertainment Tonight that Richards, 47, is seeking treatment.
On last season's finale, Richards battled it out with her sister Kyle, who called her an alcoholic.
In October, new costar Brandi Glanville accused Kim of being "wasted out of her f---ing mind" during a game-night episode. Kim strongly denied it during a shouting match that became one of the show's biggest fights so far this season.
The reality star (whose niece is Paris Hilton) revealed in a November episode that she's been taking anti-anxiety and antidepressant medications, along with an anti-seizure medication which can be used to treat alcoholism.
