After doctors told Kayes Uddin that he would probably only have two years to live, he decided to do something about it. Since 2011, he went from 420 lbs. to 182 lbs.

The father of three had issues sleeping, and his breathing would stop around 80 times per night, forcing him to wear a sleeping mask to prevent his throat from closing up.

“I couldn’t walk without getting out of breath. Playing with the children left me exhausted and I knew I had to do something but didn’t know where to start,” he told the Daily Mail.

Uddin decided to undergo gastric bypass surgery. "Being diagnosed with sleep apnea was my lowest point. To be told my breathing was stopping at night because I was so fat was terrifying,” he said.

Sleep apnea is a chronic disorder where breathing repeatedly stops and starts during a person’s sleep. The pause in breath can last from a few seconds to a few minutes — sometimes occurring 30 times or more an hour.

According to the Mayo Clinic, obstructive sleep apnea can affect almost anyone, but it is most common in middle-aged and older adults and people who are overweight. It often goes undiagnosed and can cause a number of long-term health problems, including excessive sleepiness.

Now, because of the surgery, Uddin’s apnea is no longer present, and he is able to sleep without using a mask. He plans to keep off the weight by making healthy changes in his life, including walking to work every day and running three miles almost every evening.

“The whole family has benefited. We have all adopted a totally healthy new approach to our eating and fitness. I can easily keep up with the children now and they love having the fit dad they deserve,” said Uddin.
