The morbidly obese people featured on "My 600-lb Life" (Wed., 9 p.m. EST on TLC) faced many challenges on their long journeys toward a healthier lifestyle.
Not least was the danger posed to their lives by the various surgical procedures that they had to undergo.
Henry embarked on his journey at the age of 47, weighing 750 lbs and determined to lose weight so he could attend his high school reunion.
After losing a huge amount of weight Henry had a lot of excess skin that needed to be removed. However, when he went in for his second removal surgery, things went wrong.
Henry's heart stopped and the doctors had to resuscitate him.
Talking about the experience later, Henry described what it felt like to die. "I saw a white light. It was just like having an out of body experience," he said.
"There was the light to take me to Heaven [but] I wasn't ready for it," he added, "because there's so much here on earth I haven't did yet."
Henry grabbed onto his second chance at life with both hands and went on to lose an astonishing 475 lbs on his seven-year journey toward a normal life. Now, at the age of 53, Henry had found true love and was preparing for his wedding.
