Strictly Come Dancing star Amy Dowden was body shamed by a professional dancer, but says that dancing has been her "saviour".
The 32-year-old who has Crohn's disease, recalled the moment she was told she had a "fat bottom" and a "thick middle" by a fellow dancer.
Amy, who takes steroids to help her manage her condition, says that she also gets abused online for the way she looks.
In an interview with the BBC, she explained that the steriods she takes can lead to weight gain.
"I can remember doing a dance competition when I was about 19 or 20, I'd been on a really high dose of steroids and it bloated me a lot - and my face changed, I called it the guinea pig face. My costume was really tight.
"It took me a lot to get on the dance floor. I remember walking onto the floor and this professional dancer shouted out "she's got a fat bottom" and a "thick middle" - well, that's the polite way of saying it. That comment has stayed with me for the rest of my life and when I go on steroids, it's the first thing I hear," she said.
"She didn't know what I'd been through and instead of dancing I just wanted to run off and cry."
Amy, who has had Crohn's since she was 11, said how she gets trolled online, with one person accusing her of having "thunder thighs", which she said "hurts".
Crohn's disease is a lifelong condition which affects the digestive system.
Symptoms include stomach aches and cramps, diarrhoea, blood in stools, weight loss and fatigue.
Most people with the disease take medicine to reduce the inflammation of the digestive system, or like Amy use steroid tablets.
In some cases surgery is needed to remove a small part of the digestive tract.
To help encourage people to stop body-shaming, Amy has launched her own podcast Amy Dowden: Body Shaming and Me.
She explained how tough it can be living with an "invisible illness" and how every day can be a battle.

The dancer compared hurtful comments to putting a nail through a piece of wood.
She said that even when the nail has been removed from the wood, the dent will be left there, adding that every time someone says something unkind to someone it leaves a mark.
Amy will be on the Strictly Come Dancing Christmas Special, which airs on BBC One at 5.10pm on Christmas Day.
