Symptoms of Anorexia nervosa

The symptoms of anorexia nervosa include loss of weight and changes in other physical features, together with a change in personality and behaviour.

Changes to physical features may include:

  • Slow progressive weight loss, often starting with a normal weight reducing diet. In children and teenagers, there will be inadequate weight gain in relation to growth.
  • Swollen stomach, constipation or diarrhoea and stomach (abdominal) pains.
  • Fainting, dizzy spells, poor circulation and feeling cold.
  • Downy hair growth on the body, dry, rough and discoloured skin.
  • Ceasing of menstrual periods in women, loss of libido in men, delay of puberty or stunted growth.
  • Loss of bone mass and the onset of osteoporosis (brittle bone).
  • Insomnia and fatigue.
  • Low blood pressure and changes to pulse rate and rhythm.
  • Blood changes, including anaemia, low white cell count, plasma and platelet abnormalities.
  • Salt imbalance, liver and kidney damage.

Personality and behavioural changes may include:

  • Increasing seriousness, introversion and mood swings.
  • Denial of the existence of a problem.
  • Intense fear of gaining weight, with a distorted perception of body shape. Even a normal, healthy body weight may arouse feelings of tension and panic. May spend excessive amount of time in front of a mirror and may see themselves as very fat despite visual evidence to the contrary.
  • Over exercising and restless behaviour.
  • Guilt, loss of confidence and self esteem, less assertive and more dependant.
  • Narrowing of interests, attention becoming focused on diet.
  • Secret vomiting and/or taking laxatives.
  • Use of appetite suppressants and/or diuretics.
  • Rituals attached to eating and hiding food.
  • Wearing baggy clothes.
