What was the official cause of Frida Kahlo’s death?

The official cause of Frida Kahlo’s death was a pulmonary embolism.

Kahlo died on July 13, 1954, at Casa Azul in Coyoacán. Her death certificate listed pulmonary embolism, meaning a blood clot blocked an artery in the lungs. She was 47 years old.

Kahlo had lived with severe chronic pain and serious health problems for much of her life. A childhood bout of polio, the injuries from her 1925 bus accident, and numerous surgeries all affected her mobility and physical condition.

Some later writers have questioned whether an overdose may also have contributed, but pulmonary embolism remains the official recorded cause. Because the evidence is incomplete, accounts should distinguish the documented cause from later speculation.
