Heavy D performs onstage during an event in Las Vegas on June 15.
Jamaican-born and Mount Vernon-raised rapper Heavy D died of natural causes, the Los Angeles coroner's office said Tuesday.
The self-proclaimed "overweight lover" of hip-hop, who became one of rap's top hit makers with a combination of humor and positivity, collapsed outside his Beverly Hills home on Nov. 8.
The 44-year-old rapper, whose real name was Dwight Errington, died later at a hospital.
Coroner's office spokesman Craig Harvey said Tuesday that weight and a transcontinental jet flight were contributing factors.
The cause of death was pulmonary embolism and deep leg vein thrombosis. He also had arteriosclerotic cardiovascular disease.
Heavy D became one of the genre's most integral stars in the late 1980s and early 1990s. His hit "The Overweight Lover's in the House" played up his hefty frame.
