"My 600-lb Life" star Sean Milliken has died at 29.

"TLC is saddened to share that Sean Milliken has passed away," the network said in a statement Tuesday. "TLC expresses its deepest sympathies to Sean’s friends and family at this difficult time."

His father, Matt Milliken, announced the news on Facebook, according to TMZ. He wrote that his son died in a hospital following complications from an infection: "Sunday he was having problems with his breathing, they were able to resuscitate him and a short time later his heart stopped."

Milliken first appeared on TLC's "My 600-lb Life" in 2016, when he weighted over 900 pounds. He admitted to turning to food at a young age to cope with his tumultuous relationship with his father.

"It was scary. So I would eat. And suddenly I felt a lot better," Milliken said during the episode after accusing his father of verbal abuse. "In that moment, nothing else mattered."

During the show, a bedridden Milliken moved to Houston with his mother, Renee, to undergo weight-loss surgery, which helped him successfully lose over 400 pounds.

TLC camera crews caught up with Milliken last summer during an episode of "My 600-lb. Life: Where are They Now?" He was reeling over the unexpected death of his mother.

"A couple of months ago my mom went to the hospital because she wasn’t feeling well, and she just kept getting worse," Milliken said during the episode. "They said she had renal failure, and she didn’t make it. She passed away a couple weeks ago and I’m devastated, and I don’t know what to do now because my mom was everything to me."

Despite losing his mother, TLC said Milliken was "still continuing in his quest to live a healthier and happier life."

Milliken's death marks the third individual from "My 600-lb. Life" to die in the last six months. James "L.B." Bonner, 30, died from a self-inflicted gunshot wound in August and Lisa Fleming died later that month at age 50.
