Rumination disorder is a condition in which a person will unintentionally/unconsciously bringing up food from the stomach into the mouth (regurgitation) and rechewing the food and either swallowing the rechewed food or spitting it out, usually during or soon after eating. Unlike puking, regurgitating doesn't feel forced, regurgitating almost seems to happen naturally, without effort, like a normal reflex of your bodies' organs.

Rumination seems to be a spectrum, as in everyone experiences it differently and on different levels. Some people have their physical health completely deteriorate to the point of hospitalization, while others may not even notice that they have Rumination Syndrome to begin with.

Some people associate Rumination Syndrome with eating disorders (specifically Bulimia) due to the fact that they are similar in nature, but doctors have not found a direct link between Rumination Syndrome and any eating disorders.

If you think you may have Rumination Syndrome, please look at a more detailed and professional website with more detailed facts and see a doctor as soon as possible. Rumination Syndrome can be a very serious health concern and have a lot of negative effects on your life.
Person 1: "How come you never eat a lot?"
Person 2: "It's because of my Rumination Syndrome, it causes me to regurgitate most of the food I eat, so it's uncomfortable for me to eat a lot."

Co-ruminating has nothing to do with cows…but it can be bad for girls.

Is a way for adolescents (especially girls) to create new source of depression and anxiety fixating on their problems and excessively talking with another person about problems through Sms text, e-mails, chats, social networks, creating a "vicious cycle" that feeds on itself snowballing rapidly to depression.

"Dude, I could have earned way more brownie points with Paige had I just tried to be more flirty. Now she probably thinks I'm a wank or thinks I’m not interested in her. Wait. Shit, SHIT! I gotta snap out of this PIIR."
"You're not a wank. And what's PIIR?"
