People with a disorder in which they are convinced they are ugly have a brain glitch when processing things they see, researchers say.

The findings, published in the journal Archives of General Psychiatry, shed light on body dysmorphic disorder (BDD), marked by a dramatically distorted self-image and obsessive thoughts about imagined or minor defects in their appearance.

University of California psychiatry professor Dr Jamie Feusner says an estimated 1 to 2 per cent of people around the world have BDD.

Some undergo repeated cosmetic surgery procedures in a futile attempts to fix the problems.

The cause of the disorder remains unknown, with experts suspecting that a variety of factors may contribute, from genetics to upbringing.

Now I feel bad for a whole group of people I'd never known about before.

To me, that sounds like the first stage of problem solving. They know something is wrong, don't like what they see but can't put their finger on the solution. Knowledge before choice, measure twice cut once. Those people just seem to be measuring over and over and over again or seem to measure once and cut thinking faith will guide their choice.

I don't see Self-Image as a disorder even if it includes not liking one's self. I've grown up thus far not liking myself and I don't consider it a disorder, I don't like the feeling I get when I see myself in the mirror but I don't sit there in front of the mirror for hours wondering how to make it better. I move on with my day and if someone doesn't like how I look, well sucks to be them.
