Causes of Eating Disorders
The causes of eating disorders are complex and usually involve a combination of psychological, biological, and environmental factors. While each person’s experience is unique, certain patterns often emerge. Understanding the causes of eating disorders is vital for prevention, early intervention, and effective treatment.
One of the most significant psychological contributors is low self-esteem. Many individuals who develop eating disorders struggle with feelings of inadequacy, perfectionism, or a strong need for control. They may believe that controlling their food intake or body shape is the only way to feel valued or accepted.
Trauma is another major factor. People who have experienced emotional, physical, or sexual abuse are at greater risk. In such cases, disordered eating may become a coping mechanism—a way to manage painful emotions or reclaim control over the body.
Biological factors also play a role. Research shows that eating disorders may run in families, suggesting a genetic component. Chemical imbalances in the brain, particularly involving serotonin and dopamine, are thought to affect mood, appetite, and impulse control—all of which influence eating behaviours.
Cultural and environmental pressures contribute significantly. In today’s world, where thinness is often equated with beauty and success, people—especially young women—may feel pressured to conform to unrealistic body ideals. Constant exposure to filtered images, diet culture, and social comparison fuels body dissatisfaction and unhealthy behaviours.
Peer pressure and bullying, especially about weight or appearance, can also trigger disordered eating. Adolescents are particularly vulnerable, as their self-image is still forming. In boys, eating disorders may be linked to muscle dysmorphia—an obsession with gaining muscle mass rather than becoming thinner.
In South Africa, cultural dynamics vary, but modern beauty standards have become increasingly influential across different communities. Many South Africans report struggling with body image due to social media, weight stigma, or conflicting cultural messages around body size.

Family environment matters too. Households where weight is frequently discussed, dieting is common, or emotional expression is discouraged may unknowingly contribute to disordered eating patterns. Parents with eating disorders may also model unhealthy behaviours that children then adopt.
Academic or career stress can be another trigger, particularly in high-achieving individuals. Food may become one of the few areas they feel they can control. Over time, rigid behaviours around food can escalate into a full-blown disorder.
Understanding the causes of eating disorders helps break the myth that they’re simply about food. They are, at their core, emotional conditions requiring empathy, psychological support, and a holistic approach to healing.
