Important: Eating disorders are serious mental health conditions that require professional treatment. This information is educational and not a substitute for medical diagnosis. If you're concerned, please consult a healthcare provider.
Anorexia Nervosa
Anorexia nervosa is characterized by extreme restriction of food intake, intense fear of weight gain, and distorted body image.
Key Symptoms:
- Severe food restriction and low calorie intake
- Significantly low body weight (but not always visible)
- Intense fear of gaining weight or becoming fat
- Distorted body image or denial of low weight seriousness
- Excessive exercise or compensatory behaviors
- Preoccupation with food, weight, and body shape
Physical Health Consequences:
- Malnutrition and vitamin deficiencies
- Heart problems and irregular heartbeat
- Bone loss (osteoporosis)
- Loss of menstrual period
- Fatigue and weakness
- Hair loss and dry skin
- Low blood pressure
- Organ damage (if severe)
Treatment Approaches:
Medical monitoring, nutritional rehabilitation, psychotherapy (CBT, FBT), and addressing underlying psychological factors.
Bulimia Nervosa
Bulimia nervosa involves cycles of binge eating followed by compensatory behaviors like purging, fasting, or excessive exercise.
Key Symptoms:
- Recurrent episodes of binge eating (eating large amounts in short time)
- Feeling lack of control during binges
- Compensatory behaviors (vomiting, laxatives, fasting, excessive exercise)
- Self-evaluation overly influenced by body shape and weight
- Often occurs at normal or above-normal weight
Physical Health Consequences:
- Electrolyte imbalances (can be life-threatening)
- Tooth decay and gum disease
- Esophageal damage
- Digestive problems
- Swollen salivary glands
- Dehydration
- Heart problems
- Chronic sore throat
Treatment Approaches:
CBT (Cognitive Behavioral Therapy), nutritional counseling, medication (sometimes), and addressing binge-purge cycles.
Binge Eating Disorder (BED)
Binge eating disorder is the most common eating disorder, characterized by recurrent binge eating episodes without regular compensatory behaviors.
Key Symptoms:
- Recurring episodes of eating large amounts of food
- Eating much more rapidly than normal
- Eating until uncomfortably full
- Eating when not physically hungry
- Feeling disgusted, depressed, or guilty after overeating
- Eating alone due to embarrassment
- No regular purging or compensatory behaviors
Associated Health Issues:
- Weight gain and obesity (though not always)
- Type 2 diabetes risk
- High blood pressure and cholesterol
- Heart disease risk
- Joint and muscle pain
- Psychological distress and shame
Treatment Approaches:
CBT, dialectical behavior therapy (DBT), interpersonal psychotherapy, and sometimes medication.
Avoidant/Restrictive Food Intake Disorder (ARFID)
ARFID involves avoiding or restricting food intake, but not due to concerns about weight or body image.
Key Symptoms:
- Avoidance based on sensory characteristics (taste, texture, smell)
- Lack of interest in eating or food
- Concern about aversive consequences of eating (choking, vomiting)
- Significant weight loss or failure to gain weight
- Nutritional deficiencies
- Dependence on nutritional supplements
- Interference with social functioning
Treatment Approaches:
Exposure therapy, family-based treatment, addressing sensory issues, nutritional rehabilitation, and anxiety management.
Other Specified Feeding or Eating Disorder (OSFED)
OSFED includes eating disorders that cause significant distress but don't meet full criteria for other diagnoses. Equally serious and requires treatment.
Examples Include:
- Atypical Anorexia: All criteria for anorexia except weight is in normal or above-normal range
- Purging Disorder: Purging without binge eating
- Night Eating Syndrome: Recurrent episodes of night eating
- Bulimia (Low Frequency): Binge/purge cycles less frequent than typical bulimia
Treatment Approaches:
Individualized based on specific symptoms, often similar to treatment for related eating disorders.
