Mom hopes to appear on My 600lb Life after surgery to get more help
An Iowa mother who weighs 765lb is trying to get on a reality TV show because she believes it is the only way to save her life.
Charity Pierce finds moving around so difficult that she is almost house bound, but doctors near her Cedar Rapids home say she must slim down to 500lb before they can give her a gastric band.
The 38-year-old has been shortlisted to appear on TLC's My 600lb Life and a hospital in Houston is willing to operate, but only if she can get to Texas for an appointment by the end of April.

Because Ms Pierce, who is the fattest woman in the world, has developed a medical condition called lymphedema, which has caused a huge swelling on her left leg, she no longer fits easily into a regular car.
To make the 1,000 mile trip to Texas the single mother would need to hire a private ambulance, and she is currently trying to raise $5,000 to pay for it.
'A doctor in Texas willing to do patients over 600lb [is] my only hope,' she wrote on her Go Fund Me page, which is still a few thousand dollars below her target.
'The one thing that's going to save my life is gastric bypass. But I'm a single mother on disability with no one to count on besides myself,' she added.
She hopes to be able to lose enough weight to be able to watch her daughter grow up, and also so she can have a dream wedding to her 22-year-old boyfriend, Tony Sauer.
'I'm determined not to have to get married at home. I want to be able to walk up the aisle,' Ms Pierce told Best magazine.
'I plan to wear a wedding dress, cowboy boots and a cowgirl hat ... I want to dance all night.'
Ms Pierce says she has always been on the larger size, but her weight problem became worse after developing lymphedema, which blocks the lymphatic system and causes swelling.
'The lymphedema feels like another whole person. It feels like cinder blocks hanging off you all the time,' Ms Pierce told ABC9.
The swelling that protrudes out the side of her leg makes exercise and walking difficult and has made her almost entirely house bound as she struggles to fit inside cars.
She first turned to TV show doctors for help in 2012, when she released a video on YouTube pleading for someone to get her case to Dr Phil.
She explained that she developed lymphedema in 2001 after falling down a flight of stairs, and then had to fight off Necrotizing Facitis, the flesh eating bacteria, in her abdomen.
'They had to cut out 40lb of dead muscle and tissue. My left side looks as though a shark took a big bite out of it,' Ms Pierce said.
The single mom said she is determined to lose weight so she can live to see her daughter, Charly, graduate and get married.

'I'm not going to make it if I don't have a gastric bypass,' she said.
Charly added: 'She's doing really well about trying to keep her mobility, but I feel like if she doesn't get help soon that's not going to be an option. She's just not going to last much longer.'
Ms Pierce is trying to lose weight and is on a limited 1,200-calorie a day diet and does physical therapy twice a day.
She hopes that if the consultant in Texas agrees to fit a gastric band she will be able to appear on My 600lb Life and receive further help in getting back in shape.
'It's a very long road, but I'm going to get there,' Ms Pierce said.
