(Scroll down for video) A young boy is suffering from a rare disease that leaves him starving all day, no matter how much he eats.
Sadly, there is no cure for this terrible disease and there is no way to help him feel full.
The unfortunate eight-year-old boy was diagnosed with a disease called Prader Willi syndrome.
Chase Grey was diagnosed with this disease when he was only a few weeks old.
"For a couple of days I was in denial, thinking 'no way, it's my beautiful son. Nothing can be wrong with him,'" his mother, Robin Grey, said.
Chase is always hungry and the food in the house must be locked away. He will eat non-stop because he never feels full.
“The refrigerator is tied, the pantry has a lock and there can never be food out on the table or counter. The older he gets the more desperate for food he is and he eats anything he can get his hands on, including cat food," his mother said.
The disease leaves the person starving as if he had not eaten in two days. Prader-Willi syndrome affects one in 15,000 people. Dr. Sharon Travers is one of Grey’s doctors at Children's Hospital. She said that most children with Prader Willi are growth hormone deficient.
"Many children start growth hormones soon after diagnosis. Grey began taking hormones when he was only a few months old. Because of that he is a now normal height," Travers said.
Kids with this terrible disease have behavioral problems, such as extreme mood swings, learning disabilities and other issues. Sadly, most adults with Prader Willi syndrome are obese, and as they grow, the need for food grows.
"If left unchecked, they just eat and eat and eat. People with this syndrome have a hard time living on their own. If they were to live on their own, they are likely to overeat and have an early death from complications of obesity," Travers said.
"There is nothing worse than a mother to see her son in pain," Robin Grey said. Prader Willi is not only difficult physically and emotionally, it also carries a huge financial burden. It costs the Grey family more than $30,000 a year to support the growth hormone therapy, physical therapy and doctors.
Sadly, so far, there is no medication or surgical intervention that can help people with Prader Willi syndrome.
