Pregorexia – Dangerous Pregnancy-Related Eating Disorder

Pregorexia represents a lesser-known yet clinically significant eating disorder that emerges exclusively during pregnancy. The term is a portmanteau of "prego," derived from the Italian word for pregnancy, and "-rexia," a suffix associated with anorexia nervosa, reflecting its psychological underpinnings. First coined in 2008, the concept was introduced to describe pathological eating behaviors in pregnant women, though it has not yet been formally recognized in medical taxonomies, remaining primarily within the realm of popular psychology. This disorder is characterized by an obsessive preoccupation with body weight control and an active resistance to the physiologically necessary weight gain during gestation. Initial cases were identified in Western countries, including the United Kingdom and the United States, where a troubling pattern emerged: pregnant women deliberately restricted caloric intake and engaged in extreme weight-loss practices despite the elevated nutritional demands of pregnancy, thereby jeopardizing both maternal and fetal well-being.

While the etiology of pregorexia remains an active area of scientific inquiry, there is a consensus that its development is multifactorial, encompassing sociocultural, familial, psychological, and biological-physiological dimensions. Given its similarities to anorexia nervosa, several variables have been identified that significantly elevate the risk of this eating disorder emerging during pregnancy. Potential predisposing factors include: negative body image perception, fear of weight gain, body mass fluctuations, chronic stress exposure, depressive episodes, hormonal alterations associated with pregnancy that influence appetite regulation, lack of emotional support from one’s social environment, unsatisfactory intimate relationships, familial history of pregorexia, perfectionistic and obsessive-compulsive tendencies, susceptibility to anxiety states, diminished self-esteem, attempts to exert control over life circumstances through dietary restriction, comorbidity with other psychiatric disorders, traumatic life experiences, childhood experiences of rejection or neglect, and exposure to violence. Empirical research indicates that individuals diagnosed with psychogenic eating disorders frequently exhibit distinctive personality and behavioral patterns that cannot be attributed solely to restrictive eating habits. Patients can be categorized into three primary profiles: the borderline type (characterized by unstable self-worth, impulsivity, and perfectionistic strivings), the neurotic type (dominated by anxious traits and dependency tendencies), and the psychotic type (co-occurring with other mental health disorders). Notably, it is not only traumatic experiences such as rejection or domestic violence that heighten vulnerability to pregorexia—comparable risk levels are observed in women raised in overprotective family environments, where excessive parental control over a child’s nutrition may reinforce maladaptive eating patterns that persist into adulthood.

Extreme dietary restrictions during pregnancy exert a profoundly detrimental impact on the physiological functioning of an expectant mother’s body. Severely limiting the caloric intake of consumed meals not only results in generalized physical exhaustion but also leads to profound deficiencies in essential micro- and macronutrients, including critical vitamins and minerals indispensable for optimal health. Such practices frequently give rise to adverse effects, such as chronic fatigue, vertigo, and impaired cognitive focus. Some pregnant women further compound these risks by using laxatives or diuretic medications, which disrupt electrolytic balance and may precipitate serious complications, including dehydration or hypokalemia. Insufficient body weight during the prenatal period also elevates the likelihood of developing iron-deficiency anemia, which can adversely affect mental well-being and increase susceptibility to postpartum depressive episodes (as evidenced by research conducted by Wójciak R.W., Mojs E., and Michalska M.M. in 2013). Poorly balanced nutrition may additionally contribute to the onset of arterial hypertension and heighten vulnerability to osteoporosis in later life, a consequence of prolonged deficiencies in calcium and vitamin D.

Inadequate nutritional intake during pregnancy exerts a profoundly detrimental effect on fetal development, posing substantial risks to the child’s healthy growth trajectory. Severe caloric restriction in an expectant mother’s diet precipitates irreversible developmental impairments, encompassing both physical and cognitive domains. The use of laxatives or diuretics by pregnant women in an attempt to control weight leads to chronic deficiencies in critical micro- and macronutrients, thereby compromising the fetus’s vital functions. Empirical research conclusively demonstrates that mothers with an abnormally low body mass index (BMI) during gestation exhibit a markedly higher incidence of perinatal complications, including neonatal mortality (Kapka-Skrzypczak et al., 2011). Furthermore, restrictive dietary practices induce iron deficiency, which in turn results in permanent damage to brain structures responsible for cognitive functions in the child (Wójciak et al., 2013). Of particular concern is the impaired development of the placenta, its premature detachment, or preterm rupture of membranes—conditions that may culminate in miscarriage. Offspring born to mothers afflicted with pregorexia display an elevated susceptibility to congenital malformations, underdevelopment of internal organs, and systemic physiological dysfunctions (Ehmke vel Emczyńska, Bebelska, Czerwonogrodzka-Senczyna, 2012). Low birth weight, a common sequela of maternal malnutrition, predisposes individuals to metabolic disorders such as type 2 diabetes, as well as cardiovascular diseases later in life (Kapka-Skrzypczak et al., 2011). Additionally, maternal eating disorders significantly amplify the likelihood of psychiatric disorders manifesting in offspring during adulthood (Micali et al., 2014).

The treatment of pregorexia, much like other eating disorders, represents an exceptionally intricate and protracted therapeutic process that necessitates the involvement of a specialized interdisciplinary team. Optimal management should integrate the collaborative efforts of obstetricians, midwives, clinical psychologists, psychiatrists, internists, registered dietitians, and psychodietitians to formulate a tailored treatment regimen. A cornerstone of the therapeutic approach is comprehensive nutritional education, which enables expectant mothers to comprehend how excessive dietary restrictions adversely affect both their physiological well-being and fetal development, thereby heightening awareness of the associated hazards. Equally critical is psychotherapeutic support, aimed at uncovering the underlying psychological drivers of compulsive weight control behaviors and equipping patients with adaptive coping mechanisms. Hospitalization becomes imperative when weight loss exceeds 25% of pre-pregnancy baseline and/or when hypokalemia (<2.5 mmol/L) is accompanied by electrocardiographic abnormalities. Immediate medical intervention is mandated for patients exhibiting peritoneal signs or cardiac enzyme derangements. Preventive strategies should encompass routine monitoring of gestational weight gain, meticulous review of pharmacological agents, and dietary supplements to mitigate the risk of disorder onset and its deleterious consequences for maternal and fetal health.

Pregnancy represents a period during which women exhibit heightened vigilance regarding their health—not solely for personal well-being but primarily due to their responsibility for the developing fetus. Consequently, their dietary habits become meticulously balanced, emphasizing unprocessed, nutrient-dense foods abundant in vitamins, trace minerals, and essential nutrients. Regular physical activity also assumes greater importance as a cornerstone of a health-conscious lifestyle. However, even the most beneficial behaviors, when pursued to excess or without proper oversight, can yield outcomes directly contrary to their intended purpose. Some expectant mothers harbor concerns about excessive weight gain, potentially leading to overly restrictive dietary practices. Meanwhile, weight gain during pregnancy constitutes a physiological necessity, critical for optimal fetal development as well as for preparing the maternal body for childbirth and subsequent breastfeeding. The demand for key nutrients—such as folic acid, iron, and calcium—increases substantially, meaning that any severe caloric restriction or exclusion of entire food groups may pose serious risks to both maternal health and fetal growth, potentially resulting in irreversible consequences for both parties.
