4.6: Body Image, Eating Disorders, and Low Body Weight

Body Image, Eating Disorders, and Low Body Weight

Body image, eating disorders, and low body weight are interconnected aspects of physical and mental health that profoundly impact individuals' well-being. Body image involves how people perceive, feel, and behave toward their bodies, influencing their self-esteem and mental health. Disruptions in body image can lead to severe conditions like eating disorders, which are characterized by abnormal eating behaviors and distorted views of weight and shape. These disorders can result in significant physical, psychological, and social consequences. Additionally, while much attention is given to the health challenges of overweight and obesity, low body weight also carries serious risks, such as nutritional deficiencies, weakened immunity, and increased mortality. Understanding these topics is essential for promoting healthy body perceptions, preventing disordered eating, and supporting individuals in achieving balanced and sustainable health.

Body Image

Body image refers to how you see, feel, and act toward your body. Body image is a multidimensional concept that includes^[11]:

• Cognitive: thoughts and beliefs about the body
• Perceptual: How you perceive your body's size and shape.
• Affective: feelings about the body
• Behavioral: the actions that people perform to check on, tend to, alter, or conceal their body

Factors affecting body image and body image disorders include: BMI, family, social pressures, media, social media, self-esteem, chronic illness, depression, and sexual abuse.

A person with a positive body image perceives their body accurately and accepts its various aspects as they truly are. Body positivity, also known as body satisfaction, involves feeling comfortable and confident in one’s body, embracing its natural shape and size, and understanding that physical appearance has little bearing on one’s character or value.

A person with a negative body image or a distorted perception of their body may experience feelings of shame, anxiety, and self-consciousness. People who experience high levels of body dissatisfaction feel their bodies are flawed in comparison to others, and they are more likely to suffer from feelings of depression, isolation, low self-esteem, and eating disorders.

Eating Disorders

While there is no single cause of eating disorders, research indicates that body dissatisfaction is the best-known contributor to the development of eating disorders and body dysmorphic disorder. Body dysmorphic disorder (BDD) is a distressing preoccupation or a markedly excessive concern with one or more perceived or slight defects in physical appearance, associated with significant distress and functional impairment.

Eating disorders are serious and often fatal illnesses that are associated with severe disturbances in people’s eating behaviors and related thoughts and emotions. They are associated with a wide range of adverse psychological, physical, and social consequences. A person with an eating disorder may start eating smaller or larger amounts of food, but at some point, their urge to eat less or more spirals out of control. Severe distress or concern about body weight or shape, or extreme efforts to manage weight or food intake, also may characterize an eating disorder.

Eating disorders are real, treatable medical illnesses. They frequently coexist with other illnesses such as depression, substance abuse, or anxiety disorders. Other symptoms can become life-threatening if a person does not receive treatment, which is reflected by anorexia being associated with the highest mortality rate of any psychiatric disorder.

Anorexia Nervosa

Many individuals with anorexia nervosa perceive themselves as overweight, even when they are significantly underweight. This disorder often manifests as an obsession with eating, food, and weight control. Those affected may frequently weigh themselves, meticulously portion their food, and consume only small quantities of specific items. In some cases, they may also engage in behaviors such as binge eating followed by extreme dieting, excessive exercise, self-induced vomiting, or the misuse of laxatives, diuretics, or enemas.

Symptoms of anorexia nervosa include:

• Extremely low body weight
• Severe food restriction
• Relentless pursuit of thinness and unwillingness to maintain a normal or healthy weight
• Intense fear of gaining weight
• Distorted body image and self-esteem that is heavily influenced by perceptions of body weight and shape, or a denial of the seriousness of low body weight
• Lack of menstruation among girls and women.
• Some who have anorexia nervosa recover with treatment after only one episode. Others get well but have relapses. Still others have a more chronic, or long-lasting, form of anorexia nervosa, in which their health declines as they battle the illness.

Other symptoms and medical complications may develop over time, including:

• Thinning of the bones (osteopenia or osteoporosis)
• Brittle hair and nails
• Dry and yellowish skin
• Growth of fine hair all over the body (lanugo)
• Mild anemia, muscle wasting, and weakness
• Severe constipation
• Low blood pressure, or slowed breathing and pulse
• Damage to the structure and function of the heart
• Brain damage
• Multi-organ 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

Individuals with bulimia nervosa experience recurring episodes of consuming unusually large quantities of food, often accompanied by a sense of losing control during these episodes. To compensate for the overeating, they may engage in behaviors such as self-induced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these actions.

Unlike those with anorexia nervosa, individuals with bulimia nervosa typically maintain a body weight within the normal or slightly overweight range. However, they share a similar fear of gaining weight, a strong desire to lose weight, and significant dissatisfaction with their body size and shape. Bulimic behaviors are often conducted in secrecy due to feelings of shame or disgust. The cycle of binge eating and purging can occur anywhere from a few times per week to multiple times per day.

Other 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 that can lead to a heart attack or stroke.

Binge-Eating Disorder

Individuals with binge-eating disorder struggle with a loss of control over their eating habits. Unlike bulimia nervosa, episodes of binge eating are not followed by compensatory behaviors such as purging, excessive exercise, or fasting. Consequently, people with binge-eating disorder often become overweight or obese, which increases their risk of developing conditions like cardiovascular disease and high blood pressure. These episodes are frequently accompanied by feelings of guilt, shame, and distress, which can perpetuate the cycle of binge eating.

Special Highlight: Factors Contributing to Eating Disorders and How to Help

Eating disorders are complex conditions influenced by a range of psychological, socio-cultural, and familial factors. Research has identified dissatisfaction with body image as one of the primary psychological risk factors, significantly affecting adolescents, especially girls. Media pressures, including exposure to idealized body types on social media, television, and advertisements, play a major role in shaping unhealthy perceptions of body image. Higher body mass index (BMI), low self-esteem, perfectionism, impulsivity, and depression are also linked to increased risk of developing eating disorders.

Socio-cultural influences, such as internalizing thin ideals, experiencing weight-related bullying, and cultural pressures to conform to certain aesthetic standards, exacerbate the problem. Additionally, family dynamics, including poor communication and authoritarian parenting styles, can contribute to unhealthy eating behaviors and obsessive focus on weight.

Despite these challenges, there are steps you can take if you or someone you know may be struggling with an eating disorder:

1. Listen with Empathy: Approach the individual with care and without judgment. Encourage open dialogue about their feelings and experiences.
2. Encourage Professional Help: Eating disorders require specialized treatment. Encourage the person to seek help from healthcare professionals, such as a therapist or dietitian experienced in eating disorders.
3. Avoid Triggering Language: Refrain from commenting on weight, body shape, or eating habits. Focus instead on health and well-being.
4. Promote Positive Body Image: Reinforce the value of diverse body types and highlight non-appearance-related achievements.
5. Be a Supportive Role Model: Demonstrate balanced eating habits and a healthy relationship with food and exercise.

By understanding the factors contributing to eating disorders and taking proactive, compassionate actions, we can foster healthier attitudes toward body image and nutrition, promoting overall mental and physical well-being.

Low Body Weight (underweight)

While much attention is given to the health risks of excess body fat, it is important to recognize that insufficient fat reserves can also lead to serious health issues. Fat is an essential component of a healthy body, and being underweight poses its own risks. Approximately 1.6% of U.S. adults aged 20 and over are underweight, often due to poor nutrition or underlying health conditions. Healthy body fat percentages range from 10–22% for men (with a minimum of 3–5% for essential fat) and 20–32% for women (with a minimum of 8–12% for essential fat). A BMI below 18.5 is classified as underweight.

Underweight persons may experience:

• Osteoporosis
• Skin, hair, and teeth problems
• Immune System disorders (get sick more)
• Low energy (excessive fatigue)
• Reproductive disorders: Irregular menstrual cycle and premature births
• Respiratory disorders
• Slow or impaired growth due to lack of nutrients
• Mental health issues such as Depression
• Increased mortality from external causes like accidents, injuries, and suicide^[12]

Body image, eating disorders, and low body weight are interrelated factors that significantly impact physical and mental health. Positive body image involves embracing one’s natural shape and size, while negative body image can lead to emotional distress and disordered eating behaviors. Eating disorders such as anorexia nervosa, bulimia nervosa, and binge-eating disorder are serious conditions characterized by distorted perceptions of weight and shape and harmful eating behaviors. These disorders can lead to severe physical complications, including cardiovascular issues, organ damage, and even death. Additionally, while much focus is placed on the risks of excess weight, being underweight poses significant health risks such as nutritional deficiencies, weakened immunity, and osteoporosis. Promoting a balanced approach to body image and addressing disordered eating behaviors are essential for fostering overall health and well-being.
