Kanye West 911 Call Before Hospitalization

Kanye West's behavior was so erratic when his doctor dialed 911 ... the dispatcher was worried he might hurt himself or others around him.

TMZ obtained the 911 call and once dispatch got the rundown on his condition the operator said, "Don't let him get any weapons or anything like that."

Kanye's personal physician, Dr. Michael Farzam, placed the call on November 21 ... while Kanye was at his trainer's home in L.A.

This call makes it clear ... all involved knew Kanye was in dire straits.
