Key Similarities
| Symptom | How it is similar |
|---|---|
| Distress About Your Body Shape or Weigh | Both challenges can involve intense, persistent distress about body shape or weight, which can make them look very similar from the outside. |
| Constant preoccupation with appearance | Both can involve spending a lot of mental energy focused on appearance, making it hard to shift attention away from body-related concerns. |
| Being very self-critical | Both commonly involve harsh self-judgment, especially around perceived flaws, control, or not feeling good enough. |
| Perfectionism | Both can involve rigid standards and a strong sense that the body or appearance must meet an exacting ideal. |
| Compulsive or repetitive behaviours | Both may involve repeated behaviours aimed at reducing distress, such as checking, comparing, seeking reassurance, or trying to feel more in control. |
