It's being speculated that Donda West (age 58) may have died from cosmetic surgery complications. She died on Saturday after some kind of surgery (possibly liposuction) at a hospital in Los Angeles.

She raised her famous son, Kayne West, on her own and just a few months ago she had published her book Raising Kanye: Life Lessons from the Mother of a Hip-Hop Superstar

Update: Donda West was in surgery for a tummy tuck and breast reduction. Her surgeon, Dr. Jan Adams told TMZ that her death was not related to the surgery itself but that she might have died from a heart attack, pulmonary embolism, or massive vomiting.
