Anorexia nervosa意思

"Anorexia nervosa" is a term used to describe a serious eating disorder that is characterized by an irrational fear of gaining weight, a distorted body image, and an extreme restriction of food intake. The word "anorexia" comes from the Greek words "an-" meaning without, and "orexia" meaning appetite, while "nervosa" suggests that it is a nervous condition. People with anorexia nervosa often have a distorted perception of their body weight and shape, leading them to engage in dangerous behaviors such as excessive dieting, purging, and excessive exercise, which can result in serious health consequences.
