Thomas had traveled to Jupiter, Florida, from Tennessee to have liposuction and remove previous breast implants at Bafitis Plastic Surgery. The Medical Examiner’s report said she was cleared for the procedures by a physician at home.
A representative for Bafitis Plastic Surgery did not immediately respond to PEOPLE’s request for comment, nor did a spokesperson for Williams.
The report said she was released from the facility around 7 p.m. on March 21 and was taken to a recovery facility where she was “sitting up in bed, speaking normally” the next day when she “suddenly” became unresponsive.
The report said that Thomas died in the emergency room at the local hospital.
The autopsy report revealed she also suffered from ailments including mild brain swelling, mild coronary artery disease and fatty metamorphosis of the liver, which is common in people with a history of alcoholism.
