An obese mum whose size caused her to have six miscarriages shed half her body weight to have more kids - and is now expecting her second child.

Hailey Frazer, 25, dropped a staggering 10st 2lbs after enduring a heartbreaking cycle of miscarriages - which doctors blamed on her size 26 frame.

The stay-at-home mum and part-time florist weighed 21st 5lbs at her heaviest.

She underwent gastric sleeve surgery after doctors told her it would be "near impossible" for her to lose weight due to thyroid issues and polycystic ovary syndrome (PCOS).

The glam goth shed an incredible eight dress sizes to achieve her enviable 11st 3lbs, size eight figure - and is now even a part-time model for alternative fashion magazines.

And after the heartache of six pregnancy losses, Hailey and her high-school sweetheart husband Frank Frazer, 28, are expecting their second child this December after welcoming son Stryker, three, in 2015.

Hailey, who was bullied at school due to her size, said: "I've been obese for most of my life. The weight really started piling on when I was nine years old, just before puberty. My mum was really concerned.

Hailey, from San Antonio, Texas, would restrict herself to 800 calories a day and lose some weight, but then binge eat and "pile it back on".

She recalled: "It was a dangerous and unsustainable cycle. I felt disgusting.

"My husband and I got married in 2013, but I hated how I looked at my wedding. What was supposed to be the best day of my life was ruined because of my weight.

"I felt anxious the whole day and kept shying away from the cameras.

"Frank and I tried to get pregnant because we both couldn't wait to be parents, but we went through six miscarriages before having our son.

"The doctors said that my weight and PCOS was a huge issue, and was making it hard for me to conceive, and to retain the pregnancies.

Hailey went to her doctor, who discovered that she had major thyroid issues that would make it "nearly impossible" to lose the weight naturally.

Her only option was gastric sleeve surgery - and she says it was the "best decision I've ever made".

Following the procedure, Hailey's weight began melting off with the help a strict ketogenic low-carb, high-fat diet and healthy exercise - with the mum reaching her goal weight of 11st 3lbs in January this year.

And just two months later, Hailey - who now works out at the gym for an hour and a half, three to six times a week, discovered she was pregnant.

She said: "With all my health issues, I never would have been able to slim down to where I am today. Frank and I have always wanted a big family, and that was the biggest motivation for me to lose weight.
