What is anorexia nervosa, and how does it manifest itself?
Anorexia nervosa is a severe eating disorder characterized by intentional and persistent food restriction leading to significantly low body weight, an intense fear of gaining weight (even when actually underweight), and a distorted perception of one’s own body. It is one of the psychiatric disorders with the highest mortality rate. Recovery is possible—the earlier treatment begins, the better the outcomes. The French Federation for Anorexia and Bulimia (FFAB) is available at 09 69 325 900 to listen and provide guidance.
- Two main forms (DSM-5): pure restrictive form (severe food restriction ± excessive exercise, without binge-eating or purging episodes) — form with binge-eating and/or purging (restriction + episodes of binge-eating and/or vomiting, laxatives) — this second form may coexist with or progress to bulimia nervosa
- Normal-weight anorexia: it is possible to suffer from anorexia while maintaining a weight within the normal range—body image distortion and restrictive behaviors are present without visible weight loss—less commonly diagnosed, but just as serious—anorexia is first and foremost a psychological disorder
- Behavioral and physical signs: severe food restriction (obsessive calorie counting, avoidance of “forbidden” foods) — compulsive exercise — hiding thinness under loose-fitting clothing — eating rituals (cutting food into small pieces, eating very slowly) — intolerance to cold — chronic fatigue — amenorrhea (cessation of menstruation) — lanugo (fine body hair, a reaction to malnutrition)
- Risk factors: perfectionism and low self-esteem — preexisting anxiety and depressive disorders — trauma (physical, sexual, emotional) — social pressures and expectations to be thin — family history of eating disorders or mood disorders — sports or artistic pursuits that value thinness (dance, gymnastics, synchronized swimming)
- Prevalence and mortality: affects 0.5–1% of women and 0.1–0.3% of men — often begins in adolescence (ages 13–18) — Mortality rate of 5–10% (the highest among psychiatric disorders) due to medical complications and suicide risk — Early detection is crucial
Medical consequences of chronic malnutrition
- Bones and osteoporosis: malnutrition combined with amenorrhea (drop in estrogen levels) leads to rapid and irreversible bone loss — risk of pathological fractures — adolescence is the critical period for building bone mass — calcium and vitamin D3 deficiencies exacerbate this risk — bone densitometry (DXA) screening recommended after 6 months of amenorrhea
- Cardiac complications: bradycardia (heart rate < 60 bpm), hypotension, QT prolongation (risk of life-threatening arrhythmias) — the heart is a muscle that also deteriorates in cases of malnutrition — leading cause of mortality in anorexia — routine ECG monitoring during follow-up
- Electrolyte imbalances: hypokalemia (low potassium) — hypophosphatemia (risk of refeeding syndrome upon resumption of eating) — hyponatremia — hypomagnesemia — these imbalances can be life-threatening and require regular laboratory monitoring
- Severe nutritional deficiencies: zinc deficiency (altered sense of taste and appetite, hair loss, immunosuppression) — iron deficiency (anemia, severe fatigue) — magnesium deficiency (cramps, increased anxiety, sleep disturbances) — Levels of vitamins B, D, C, and zinc must be assessed and corrected as part of medical follow-up
- Other complications: gastrointestinal disorders (severe constipation, gastroparesis) — infertility related to amenorrhea — partial reversible cerebral atrophy due to malnutrition — immunosuppression with frequent infections — endocrine complications (functional hypothyroidism) — stunted growth in adolescent girls
Multidisciplinary treatment and management
- Treatment goals: restore a healthy weight (BMI ≥ 17.5, generally) — correct medical complications — treat underlying psychological disorders — reestablish a healthy relationship with food and one’s body — prevent relapses — weight restoration alone is not sufficient without psychological intervention
- Psychotherapy: CBT (cognitive-behavioral therapy) — Maudsley-based family therapy (effective for adolescent girls, strongly involves the family in refeeding) — CBT-E (enhanced CBT, transdiagnostic for all eating disorders) — Acceptance and Commitment Therapy (ACT) — treatment duration is often long (1–5 years)
- Medical refeeding: always gradual to avoid refeeding syndrome (sudden hypophosphatemia upon resumption of eating → severe cardiac complications) — hospitalization if BMI < 13, cardiac complications, or total refusal to eat — refeeding via nasogastric tube if necessary — diet enriched with calories and micronutrients
- Specialized ED team: psychiatrist/psychologist + pediatrician or internist + dietitian specializing in EDs + primary care physician — specialized facilities: hospital ED units, specialized clinics, day hospitals — essential coordination among all healthcare providers — avoid caregivers who are not trained in eating disorders
- Support for loved ones: the family is often on the front lines and may feel overwhelmed — family support programs are available (support groups, family therapy) — avoid comments about weight, food, or portion sizes — do not monitor meals in a hostile manner — encourage without pressuring — FFAB resources: 09 69 325 900 and anorexie-boulimie.fr
Recovery, Prevention, and Resources in France
- Recovery is possible and well-documented: 50–70% of people make a full recovery with appropriate treatment—recovery is a long process (often 5–7 years) with possible relapses — relapses are part of the process and do not mean failure — early intervention is the best prognostic factor
- Prevention: promoting positive body image and body diversity starting in childhood — challenging the pressure to be thin in the media and on social media — early screening by school nurses, pediatricians, and primary care physicians — training for healthcare and education professionals
- Available resources: FFAB — 09 69 325 900 (Mon–Fri 9 a.m.–9 p.m., Sat 9 a.m.–6 p.m.) — anorexie-boulimie.fr — 3114 (national suicide prevention hotline, 24 hours a day) — Fil Santé Jeunes: 3224 — eating disorder treatment centers: directory available on the FFAB website
- Role of nutritional supplements: As part of medical care, correcting deficiencies (calcium, vitamin D3, zinc, iron, magnesium) through fortified foods and targeted supplements is part of the refeeding protocol — explore our product lines for nutritional deficiencies and bone remineralization — always under medical supervision in this context
- Seek help now: if you think you may be suffering from anorexia or if you’re concerned about your eating habits and your relationship with your body, talk to your primary care physician right away—you deserve help—recovery is possible, and it starts with this first step
