In Body Dysmorphic Disorder, what is indicated by "muscle dysphoria"?

Muscle dysphoria in the context of Body Dysmorphic Disorder specifically refers to an individual's belief that their body is too small or lacks sufficient muscle mass. This manifestation highlights the concern over one's perceived muscle size and overall physical strength, which can lead to significant distress and preoccupation with these thoughts. Individuals with this form of dysphoria may engage in excessive exercise or take supplements in an attempt to improve their physique, reflecting their distorted perception of body image.

This condition falls under the broader category of Body Dysmorphic Disorder, where individuals focus intensely on perceived flaws in their appearance, but in the case of muscle dysphoria, it specifically centers on muscularity and body size rather than other aspects of physical appearance. The other options address different aspects of body perception, but they do not capture the specific preoccupation with muscle size and development that characterizes muscle dysphoria.
