Illnesses that are associated with severe disturbances in people's eating behaviours and related emotions.

Anorexia nervosa

People with anorexia nervosa may see themselves as overweight, even when they are dangerously underweight. People with anorexia nervosa typically weigh themselves repeatedly, severely restrict the amount of food they eat, often exercise excessively, and/or may force themselves to vomit or use laxatives to lose weight.

Symptoms include:

Extremely restricted eating
Extreme thinness (emaciation)
A relentless pursuit of thinness and unwillingness to maintain a normal or healthy weight
Intense fear of gaining weight
Distorted body image, a self-esteem that is heavily influenced by perception of body weight and shape, or a denial of the seriousness of low body weight

Physical symptoms

Thinning of the bones (osteopenia or osteoporosis)
Mild anemia and muscle wasting and weakness
Brittle hair and nails
Dry and yellowish skin
Growth of fine hair all over the body (lanugo)
Severe constipation
Low blood pressure slowed breathing and pulse
Damage to the structure and function of the heart
Brain damage
Multiorgan failure
Drop in internal body temperature, causing a person to feel cold all the time
Lethargy, sluggishness, or feeling tired all the time
Infertility

Bulimia nervosa

People with bulimia nervosa have recurrent and frequent episodes of eating unusually large amounts of food and feeling a lack of control over these episodes. This binge-eating is followed by behaviour that compensates for the overeating such as forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviours.

Symptoms include:

Chronically inflamed and sore throat
Swollen salivary glands in the neck and jaw area
Worn tooth enamel and increasingly sensitive and decaying teeth as a result of exposure to stomach acid
Acid reflux disorder and other gastrointestinal problems
Intestinal distress and irritation from laxative abuse
Severe dehydration from purging of fluids
Electrolyte imbalance (too low or too high levels of sodium, calcium, potassium, and other minerals) which can lead to stroke or heart attack
