In 1950, Kahlo spent most of the year in Hospital ABC in Mexico City, where she underwent a new bone graft surgery on her spine.
It caused a difficult infection and necessitated several follow-up surgeries.
After being discharged, she was mostly confined to La Casa Azul, using a wheelchair and crutches to be ambulatory.
During these final years of her life, Kahlo dedicated her time to political causes to the extent that her health allowed.
She had rejoined the Mexican Communist Party in 1948 and campaigned for peace, for example, by collecting signatures for the Stockholm Appeal.


Kahlo's right leg was amputated at the knee due to gangrene in August 1953.
She became severely depressed and anxious, and her dependency on painkillers escalated.
When Rivera began yet another affair, she attempted suicide by overdose.
She wrote in her diary in February 1954, "They amputated my leg six months ago, they have given me centuries of torture and at moments I almost lost my reason.
I keep on wanting to kill myself.
Diego is what keeps me from it, through my vain idea that he would miss me. ...
But never in my life have I suffered more.
I will wait a while..." 
In her last days, Kahlo was mostly bedridden with bronchopneumonia, though she made a public appearance on 2 July 1954, participating with Rivera in a demonstration against the CIA invasion of Guatemala.
She seemed to anticipate her death, as she spoke about it to visitors and drew skeletons and angels in her diary.
The last drawing was a black angel, which biographer Hayden Herrera interprets as the Angel of Death.
It was accompanied by the last words she wrote, "I joyfully await the exit – and I hope never to return – Frida" ("Espero Alegre la Salida – y Espero no Volver jamás").

The demonstration worsened her illness, and on the night of 12 July 1954, Kahlo had a high fever and was in extreme pain.
At approximately 6 a.m. on 13 July 1954, her nurse found her dead in her bed.
Kahlo was 47 years old.
The official cause of death was pulmonary embolism, although no autopsy was performed.
Herrera has argued that Kahlo, in fact, committed suicide.
The nurse, who counted Kahlo's painkillers to monitor her drug use, stated that Kahlo had taken an overdose the night she died.
She had been prescribed a maximum dose of seven pills but had taken eleven.
She had also given Rivera a wedding anniversary present that evening, over a month in advance.

On the evening of 13 July, Kahlo's body was taken to the Palacio de Bellas Artes, where it lay in a state under a Communist flag.
The following day, it was carried to the Panteón Civil de Dolores, where friends and family attended an informal funeral ceremony.
Hundreds of admirers stood outside.
In accordance with her wishes, Kahlo was cremated.
Rivera, who stated that her death was "the most tragic day of my life", died three years later, in 1957.
Kahlo's ashes are displayed in a pre-Columbian urn at La Casa Azul, which opened as a museum in 1958.
