I need to identify the mental disorder that matches this example:
Ian feels his bicep muscles are not big enough, and his six pack is not defined enough. It makes him feel especially distressed. Because of this he has started spending all this time at the gym and has withdrawn from his friends.
Based on the example you provided, the mental disorder that matches these symptoms could be muscle dysmorphia or body dysmorphic disorder (BDD). This is a condition characterized by an excessive concern with perceived flaws or defects in one's physical appearance, which leads to significant distress and interference in daily life.
To reach a definitive diagnosis, it is important to consult with a mental health professional such as a psychologist or psychiatrist. They would conduct a comprehensive assessment to evaluate the individual's thoughts, feelings, behaviors, and the impact on their overall well-being.
If you suspect that you or someone you know is experiencing these symptoms, it is recommended to seek professional help. A mental health professional will be able to provide an accurate diagnosis and recommend appropriate treatment options such as therapy, medication, or a combination of both.
