Anatomy & Body Systems
Anorexia affects virtually every organ system:
Cardiovascular System: Heart muscle becomes weakened, heart rate slows dangerously (bradycardia), blood pressure drops, and heart rhythm abnormalities can develop. Risk of heart failure is significant in severe cases.
Endocrine System: The hypothalamus-pituitary-gonadal axis shuts down, leading to loss of menstrual periods (amenorrhea), infertility, and decreased sex hormones. Thyroid function becomes abnormal, and cortisol levels increase.
Gastrointestinal System: Stomach emptying slows, constipation becomes severe, and intestinal obstruction can occur. Liver function may be impaired.
Bone Health: Osteoporosis develops due to lack of estrogen and calcium, leading to fragile bones and increased fracture risk.
Neurological System: Brain volume decreases, cognitive function can be impaired, and peripheral nerve damage may occur.
Types & Classifications
Types of Anorexia
Restricting Type: Weight loss is achieved through dieting, fasting, or excessive exercise. No binge-eating or purging behaviors.
Binge-Eating/Purging Type: The individual engages in recurrent episodes of binge eating or purging behavior (self-induced vomiting, misuse of laxatives, diuretics, or other medications) after restricting.
Based on BMI:
- Mild: BMI ≥ 17 kg/m²
- Moderate: BMI 16-16.99 kg/m²
- Severe: BMI 15-15.99 kg/m²
- Extreme: BMI < 15 kg/m²
Causes & Root Factors
Genetic Factors: Having a family member with anorexia increases risk. Studies suggest 40-60% of risk is genetic. Specific genes related to hunger and satiety regulation, mood, and impulse control may be involved.
Psychological Factors: Perfectionism, anxiety, and obsessive-compulsive traits are common. Low self-esteem and distorted body image play central roles.
Biological Factors: Dysregulation of neurotransmitters involved in appetite and mood (serotonin, dopamine, norepinephrine) contributes to the disorder.
Cultural Pressures: Emphasis on thinness in media and culture contributes to body dissatisfaction.
Developmental Factors: Puberty brings body changes that can trigger dissatisfaction.
Interpersonal Factors: Teasing about weight, family conflict, and difficult peer relationships can contribute.
