‘My 600-Lb. Life’ star Dolly Martinez’s cause of death revealed

“My 600-Lb. Life” star Dolly Martinez died of congestive heart failure.

Martinez had been sick for a while with medical issues, Dolly’s mom, Staci Thurman, told TMZ Monday, adding that she went to the hospital on March 29 with “fluid on her heart and lungs.”

“She was put into a medically induced coma and placed on a ventilator the next day, but never recovered,” she explained.

Thurman noted that her daughter was surrounded by friends and family when she died, including her sister, Lindsey Cooper.

Cooper was the one to announce the news of her passing at age 30 via Facebook on Saturday.

“Dolly had the brightest personality she could light up any room with her laughter, her kindness, and her loving spirit,” Cooper wrote. “She had a way of making everyone feel special, and her warmth will stay with us forever.”
