Aaron Carter came clean on Twitter about why he’s so skinny, citing a medical condition called hiatal hernia.

The 29-year old singer wrote, “By the way ya’ll wanna know why I’m so skinny? It’s because @19 I was diagnosed with hiatal hernia, I didn’t choose that. be kind to me..”

The affliction, he says, is a stress condition affecting his appetite: “Basically I have an eating disorder.”

“I’m sorry, sometimes I really wish I did look better, or I eat more like y’all say, this life doesn’t come w much stability,” he continued.

If you don’t believe me ask my brother he was there when I was 19 diagnosed. It’s a stress eating disorder, I’m sorry I didn’t choose this.

No I don’t do drugs, yes I feel pain, I haven’t stopped working since I was 7 years old 22 years later and I still won’t give up.
