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.
