An eating disorder is a type of mental disorder that is defined by abnormal eating habits that adversely affect the individual’s physical or mental health, and often disrupt their social relationships, career, and overall quality of life.
According to a research summary compiled by the National Initiative for Eating Disorders in 2017, between 2% and 3% of Canadians — or between 725,800 and 1,088,700 Canadians — meet the diagnostic criteria for an eating disorder. Such disturbances in eating patterns may take place at any point in life; however, they frequently develop throughout adolescence and early adulthood. While we do not know what causes eating disorders to develop in some people and not in others, it is thought that advertising and media’s hyper-focus on unrealistic body images may feed eating disorders.
There are several forms of eating disorders, but the most common ones are binge-eating (binge-eating disorder, or BED), bulimia nervosa, and anorexia nervosa. These conditions can develop equally among men and women.
Also known as compulsive eating, BED is characterized by excessive food intake. It can coexist with other disorders or on its own. People who suffer from BED are usually overweight, putting them at a higher risk of diabetes, heart disease, and high blood pressure.
While this can greatly vary, individuals with BED can consume 10,000 to 20,000 calories in a single binge. By contrast, the average person eats between 1,500 and 3,000 calories per day. In some cases, a binge can last for hours and can extend to a whole day.
Symptoms of binge-eating disorder can include:
Individuals with BED may feel powerless to suppress this impulse. Some people with BED also have issues with anxiety, sadness, stress, and anger. Although it frequently develops in the late teenage years or early twenties, BED can develop at any age.
Anorexia nervosa is characterized by an incorrect body image and an accompanying fear of gaining weight. Generally, individuals with anorexia limit their calorie intake and the foods they eat. These periods of self-denial restrict the vital nutrients it needs to thrive. This then prompts the body to slow down its biological processes and conserve energy, which can damage one’s health.
Anyone, regardless of age and gender, can develop anorexia. This disorder affects between 0.5 percent of Canadian women, or approximately 150,000 people. There are no physical manifestations of early-stage anorexia; both underweight and larger-bodied persons can have anorexia.
The British Columbia Division of the Canadian Mental Health Association states that the following populations are at a higher risk of developing anorexia nervosa:
Symptoms
As was mentioned, anorexia has no specific identifying characteristics. However, people with anorexia often exhibit the following traits:
In addition to the above physical symptoms, people with anorexia nervosa frequently exhibit adverse mental or social behaviours, like lethargy, depression, withdrawing from social groups or functions. They may habitually eat alone, cut their food into excessively small pieces, or hide food throughout their living spaces. And despite the commonly-held belief that people with anorexia are frail, they may excessively or even obsessively exercise to “burn off calories.” People with anorexia frequently have body-checking (constantly judging body parts) or body-avoidance (avoiding looking at their bodies) behaviours.
Bulimia nervosa is characterized by binge-eating large amounts of food, followed by compulsive purging to avoid weight gain. Like people with anorexia, a person with bulimia has a distorted perception of their body image and persistent anxiety about gaining weight or being fat. They feel a lack of control over their behaviour, and often a sense of shame. People with bulimia may use diuretics or laxatives, self-induced vomiting, or exercise to “purge” their calories.
A Canadian Parliamentary committee found that nearly one percent of the population, or 300,000 Canadians, struggle with bulimia. Like individuals with anorexia nervosa, those with bulimia can be thin, average or largely-built; and also like anorexia, bulimia frequently manifests in adolescence or early adulthood, although people of any age can become affected. Warning signs of bulimia include:
Bulimia can also begin between late adolescence and young adulthood, and commonly affects women. As with other eating disorders, bulimia is also associated with other psychological problems like anxiety, depression, and stress. People with family members diagnosed with the illness can also develop bulimia.
The good news is that eating disorders, like other mental health problems, can be treated. With regular check-ups and proper treatment, many people with these disorders can walk the path of recovery.
