MF DOOM, whose real name was Daniel Dumile, died on October 31, 2020, from angioedema, which was a rare and severe allergic reaction to a blood pressure medication he had recently been prescribed. He had been suffering from health conditions including high blood pressure and kidney disease. MF DOOM was hospitalized in Leeds, England, where his condition worsened due to the reaction that caused swelling in his mouth and throat, leading to respiratory collapse. The death was complicated by reports of alleged medical negligence at the hospital, including delayed medication and lack of regular monitoring. His passing was publicly announced by his wife two months later, on December 31, 2020.
