Sean Milliken, who was known for starring in reality series My 600lb Life, has passed away at the age of 29, his father has confirmed.
Sean's father Matt reportedly revealed the sad news in a Facebook post, announcing that his son had passed away at a Texas hospital on Sunday after suffering 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," Matt explained, adding that his son was a 'good man' with a 'good heart'.
Network TLC has also paid tribute to Sean, tweeting a clip from My 600lb Life with a caption that read: "Rest in peace, Sean."
Many others also said he would now be reunited with his mother, who died in 2017 from kidney-related issues.
One person tweeted: "Rest In Peace Sean. You and Mom are together again. Prayers for his family."
Another wrote: "God bless you Sean . May you Rest In Peace with your Mom."
A third added: "Rest In Peace Sean, your with your mother now."
Sean had opened up about the reality of being overweight in an episode of My 600lb Life, which was filmed at his home in California.
He told viewers: "Every day I wake up I have to face the reality of what my life has become. I am so big now; I can hardly move. All I can do on my own is skooch to the end of my bed, go to the bathroom and see if my mom is awake."
His late mother, Renee, also appeared on the show, explaining how her son had to be 'taken care of from head to toe'.
"Sean has gotten so big," she said. "I can't handle cleaning him on my own anymore, and it is really important that he stays clean because he gets open sores really easily."

She added: "When you are very, very fat, your body goes this way but the fat goes another way, and so what happens is you start getting tears in your skin from that."
Referring to himself as a 'prisoner', Sean also expressed fears that he wouldn't live past 30 if he failed to lose weight, saying: "All I want is out, and I never really thought my life would end up like this."
Following Sean's appearance on the show back in 2016, he lost over 400lbs but when viewers caught up with him this past summer they learned that despite the loss of his mother, he was still trying to live a healthier life.
Rest in peace.
