A specific type of BDD is muscle dysmorphic disorder (MDD). People with MDD do not feel their bodies are muscular enough. This condition is most often seen in sports settings, such as athletic clubs and gyms.
Note that a person who enjoys bodybuilding does not necessarily have MDD. However, they may have MDD if they use anabolic steroids or growth hormones to speed up and support muscle growth.
Research shows that steroid abuse is common. Around three million people regularly use anabolic steroids for bodybuilding.
