Anorexia Nervosa

Anorexia Nervosa (AN) is a serious, life-threatening psychiatric disorder characterized by restricted caloric intake leading to significant low body weight, an intense fear of gaining weight, and distorted body image. It involves complex psychological and physiological disturbances requiring multidisciplinary care.

Etiology is multifactorial, involving a combination of genetic predispositions (heritability ~50%), psychological traits (perfectionism, rigidity), and sociocultural pressures emphasizing thinness. Neurobiological pathways, including dysregulated serotonin and dopamine signaling, contribute to the maintenance of the disorder.

Starvation leads to multi-system adaptive "hibernation." Cellularly, metabolic rate drops via thyroid axis suppression (low T3 syndrome). Hypovolemia, electrolyte depletion, and bradycardia arise from chronic energy deficiency. Hormonal shifts include amenorrhea (hypothalamic-pituitary-gonadal axis suppression) and cortisol elevation.

Global prevalence is roughly 0.3% to 1% in females. Onset typically occurs in adolescence or early adulthood. While historically female-predominant, increasing cases are reported in males and diverse age groups.

Genetic history of eating disorders, low self-esteem, participation in aesthetic or weight-based sports (ballet, gymnastics), childhood trauma, and comorbid anxiety or OCD.

A. Early Symptoms: Calorie counting, ritualistic eating, social withdrawal, increased exercise.
B. Common Symptoms: Amenorrhea, cold intolerance, dizziness, constipation, dry skin.
C. Advanced Symptoms: Lanugo, bradycardia, hypotension, muscle wasting, osteoporosis.
D. Emergency Symptoms: Syncope, cardiac arrhythmias, severe electrolyte imbalance, suicidality.

Vital signs often reveal bradycardia, hypotension, and hypothermia. Inspection shows lanugo, brittle hair, acrocyanosis, and wasting. Cardiac auscultation may reveal murmurs due to valve thinning.

A. Clinical Assessment: DSM-5 criteria evaluation.
B. Laboratory Testing: CBC, metabolic panel, ECG.
C. Imaging Studies: DEXA scan for bone density.
D. Functional Tests: Cardiac telemetry.
E. Biopsy Findings: N/A.
F. Genetic Testing: Not routinely used.
G. Differential Diagnosis: Hyperthyroidism, IBD, malignancy, depression.

Test Name: Complete Metabolic Panel
Type: Blood Test
Purpose: Assess electrolytes and renal function
Expected Findings: Hypokalemia, hypochloremia, elevated BUN
Interpretation: Indicates starvation/purging severity

DEXA Scan: Used to measure bone mineral density to assess for osteopenia/osteoporosis secondary to long-term estrogen deficiency and malnutrition.

Distinguished from Bulimia Nervosa by the criterion of low body weight; from major depression by the central preoccupation with weight; from IBD by the psychological intent regarding food.

Osteoporosis, heart failure, renal failure, permanent growth stunting, and cognitive impairment.

A. Lifestyle Modifications: Structured meal plans, supervised eating.
B. Preventive Measures: Media literacy, early screening.
C. Medical Treatment: Nutritional rehabilitation is the first-line treatment.
D. Surgical Treatment: N/A.
E. Interventional Procedures: Nasogastric feeding if medically necessary.
F. Rehabilitation: Family-based therapy (FBT), CBT-E.
G. Emergency Management: Hospitalization for medical stabilization (refeeding syndrome prevention).

Variable; roughly 50% recover, 30% improve, and 20% develop a chronic course. Mortality rate is one of the highest among psychiatric illnesses.

Screening at pediatric check-ups; promoting body positivity; early detection of warning signs.
