When we talk about anorexia and bulimia, the focus is often solely on food, weight, or body image. However, eating disorders (EDs) are complex mental health problems with multiple causes that cannot be explained by a single cause or reduced to a matter of willpower. This point is key: no one develops an ED just because they want to lose weight.
Anorexia nervosa is usually characterised by severe restriction of food intake, a deep fear of gaining weight and a distorted perception of one's own body. Bulimia nervosa, on the other hand, involves episodes of binge eating accompanied by compensatory behaviours such as vomiting, fasting or excessive exercise.
However, focusing solely on these visible behaviours is to remain on the surface of the problem. In many cases, eating symptoms function as a way to regulate emotional distress, regain a sense of control, or sustain particularly fragile self-esteem.
There is currently broad consensus that eating disorders do not have a single cause. Their development and maintenance can be explained by the interaction of multiple factors. These include psychological factors such as high perfectionism, extreme self-demand, low self-esteem, and difficulties in regulating emotions such as anxiety, guilt, or anger.
Added to this are interpersonal and family factors, such as relationship difficulties, fear of rejection, constant need for approval, or using food as a way to cope with relational tensions. Social and cultural factors also have a significant influence, especially aesthetic pressure and messages that associate personal value with physical appearance, as well as certain biological or genetic vulnerabilities that can increase risk in certain contexts.
None of these factors alone explains the onset of an eating disorder; it is usually a combination of several factors that leads to the disorder.
Current models, such as the transdiagnostic perspective, understand that different EDs share the same psychopathological core: overvaluation of weight, body shape and control, along with processes such as perfectionism, low self-esteem and emotional intolerance. This integrative view helps to understand why the same person may move from one diagnosis to another over time and why the most effective treatments do not focus solely on the diagnostic label, but on the mechanisms that maintain the problem.
Although EDs can have a significant impact on physical and emotional health, recovery is possible, especially when diagnosis and intervention occur early. The most effective approach is usually multidisciplinary and includes psychotherapy, medical monitoring, and nutritional support.
Beyond the specific approach, the fundamental thing is to have a therapeutic space that allows emotional suffering, relational patterns and the factors that maintain the disorder to be addressed, a clinical approach that focuses on the uniqueness and subjectivity of each patient, in a comprehensive and personalised way.
In summary, talking about anorexia and bulimia means going beyond the plate and the mirror. It means understanding that behind eating behaviour there is suffering, attempts at emotional regulation and unresolved needs. Looking at these disorders from a multi-causal perspective not only reduces stigma, but also allows for more empathetic, humane, and effective support. If you suspect that you or someone close to you may be experiencing an eating disorder, seeking professional help is a fundamental first step.
