Learn how anorexia nervosa causes malnutrition and disrupts the body's usual functions.

Key points

  • Anorexia nervosa can result in a slow or irregular heart rate, as well as very low blood pressure.
  • Over time, lack of vitamins and minerals can cause bones to become weaker, resulting in osteoporosis or fractures, and can cause hair to fall out.
  • Lack of nutrients for proper brain function can result in difficulties with concentration and mood swings.
  • When the body is starved of nutrition, it may not produce normal levels of hormones, which can have long-lasting effects on growth, puberty and menstrual cycles.
