Martinez’s mother, Staci Thurman, told TMZ on Monday that her daughter died of congestive heart failure.

Thurman told TMZ that Martinez had been sick for some time and was admitted to a hospital in Fort Worth on March 29 with fluid on her heart and lungs. She was put in a medically induced coma and placed on a ventilator but never woke up.

Martinez appeared on season 10 of “My 600-lb. Life” in 2022, when she was 25. The show detailed her struggles with food addiction.
