When we talk about anorexia and bulimia, the focus is often placed only on food, weight or body image. However, Eating Disorders (EDs) are complex and multi-causal mental health problems, which 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.
In anorexia nervosa, an intense restriction of intake, a deep fear of gaining weight and an alteration in the perception of one's own body are usually observed. In bulimia nervosa, by contrast, episodes of binge eating appear accompanied by compensatory behaviours such as vomiting, fasting or excessive exercise.
However, focusing only on these visible behaviours means staying on the surface of the problem. In many cases, eating symptoms work as a way of regulating emotional distress, regaining a sense of control or sustaining an especially fragile self-esteem.
There is currently broad consensus that EDs do not have a single cause. Their development and maintenance are explained by the interaction of multiple factors. Among them are psychological factors such as high perfectionism, extreme self-demand, low self-esteem and difficulties regulating emotions such as anxiety, guilt or anger.
To this are added interpersonal and family factors, such as difficulties in relationships, fear of rejection, the constant need for approval, or the use of food as a way of coping with relational tensions. Social and cultural factors also play a significant role, especially aesthetic pressure and messages that link personal worth to physical appearance, as well as certain biological or genetic vulnerabilities that can increase risk in specific contexts.
None of these factors, on its own, explains the appearance of an ED; it is the combination of several that usually gives rise to the disorder.
From current models, such as the transdiagnostic perspective, it is understood that the different EDs share the same psychopathological core: the overvaluation of weight, body shape and control, together with processes such as perfectionism, low self-esteem and emotional intolerance. This integrative view helps to understand why the same person can 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 are carried out early. The most effective approach is usually multidisciplinary and includes psychotherapy, medical follow-up and nutritional support.
Beyond the specific approach, the fundamental thing is to have a therapeutic space that allows addressing emotional suffering, relational patterns and the factors that maintain the disorder: a clinical view that places the singularity and subjectivity of each patient at the centre, in an integral and personalised way.
In short, 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 allows us to accompany in a more empathetic, humane and effective way. If you suspect that you or someone close to you may be going through an ED, seeking professional help is a fundamental first step.
