This module explains the most common eating disorders, focusing on how they affect thoughts, behaviour, and physical health.
🧠 What are Eating Disorders?
Eating Disorders are serious mental health conditions involving:
- An unhealthy relationship with food
- Intense focus on weight or body shape
- Harmful eating behaviours
They can affect both mental and physical health and may become life-threatening if untreated.
⚠️ Core Understanding
Most eating disorders involve:
- Restricting food (eating too little)
- Binge eating (eating large amounts)
- Compensatory behaviours (e.g. vomiting, over-exercising)
These behaviours can prevent the body from getting the nutrition it needs.
