Introduction. What is Bulimia Nervosa?

Bulimia is a psychiatric condition where individuals engage in binge eating and compensatory purging

The term “Bulimia” is derived from the Greek words “ox hunger,” while “nervosa” was added to signify its nervous nature. Bulimia nervosa is a psychiatric condition where individuals engage in binge eating and employ compensatory techniques to prevent weight gain, which may result in detrimental consequences. It is crucial to swiftly identify and diagnose this psychiatric disorder, provide sufficient treatment and observe progress and any medical issues likely to occur.

Criteria and Symptoms of Bulimia

Bulimia mainly occurs in late adolescence and early adulthood. Most affected individuals are female, although more boys and men likely suffer from the disorder. The number of undiagnosed cases is high among men, as they seek help less frequently.

Binge eating

Typical for this condition is binge-eating episodes usually followed by self-induced vomiting. During such episodes, individuals eat far more than most people would in a similar situation. They feel unable to stop eating and lose control over what and how much they consume. They hastily consume large amounts of food without seeming to stop.

Those affected by bulimia distinguish between “forbidden” foods, which are mostly very high in calories, and “permitted” foods with fewer calories and fat. Binge eating involves devouring foods that are readily available, quick to eat, high in calories, and actually “forbidden.” Binge-eating episodes usually happen in secret, followed by self-induced vomiting.

Purging

During the binge eating episodes of bulimia nervosa, the food is poorly chewed, and little attention is paid to taste. Above all, it is essential to be able to choke out what has been ingested later. Eating continues until an uncomfortable feeling of fullness arises, food runs out, or external disturbances occur. The excessive hastily eaten food leads finally to vomiting or use of laxatives.

Mesures Taken by Patients for Weight Reduction

To prevent weight gain, people with bulimia resort to inappropriate measures. They often induce vomiting, eat irregularly, or fast. Many also exercise excessively or use medications like appetite suppressants, laxatives, or diuretics.

Strict dieting rules, which many patients impose on themselves, often lead to a vicious cycle. Fasting leads to intense hunger, which triggers more binge eating. This reinforces the need to take countermeasures to avoid weight gain.

Body image

Body image has a strong impact on self-esteem in people with bulimia. They are often dissatisfied with their body weight and shape. Their target weight is often far below what is healthy.

Cyclical symptoms

Many individuals with bulimia experience a cycle of symptoms. They may go for months without symptoms but then go through phases of extreme disordered eating.

Family Dynamics and Bulimia

Families often exhibit control, conflict avoidance, and enmeshment, limiting boundaries. Indirect blame, devaluation, and mixed messages dominate family interactions. Conflict avoidance prevents bulimic individuals from learning effective resolution strategies. Rigid family ideals on thinness and health emphasise appearance over individuality. Ignoring personal needs fosters disconnection from hunger and satiety signals. Food is used for distraction, reward, relaxation, or maintaining family traditions. Bulimia perpetuates a cycle of restriction, bingeing, and compensatory behaviors. Dieting and fasting cause deficiencies, leading to binge-eating and subsequent discomfort. This discomfort is relieved by further fasting and vomiting, restarting the cycle.

Treatment for bulimia

As with other eating disorders, the will and motivation of the patient are prerequisites for successful treatment of bulimia nervosa. The treatment is primarily outpatient. Psychotherapists and clinical counsellors plan their treatment based on different forms of psychotherapy. The effective treatment methods are family therapy, CBT (cognitive-behavioural therapy), person-centred counselling and psychoanalytic therapy.

Involving the family

The treatment takes place in individual and group therapies, if possible, with the involvement of the legal guardians and the family system. In the case of adolescent eating disorders, it is particularly important to involve the patient’s parents in the treatment. Family counselling and family therapy have proven to be particularly effective. In addition to psychotherapy, self-help groups can be helpful as an auxiliary feature to the main treatment.

Hospitalization

If the symptoms are very pronounced or there are severe personality disorders, self-harm behaviour, or risk of suicide, hospitalisation and inpatient treatment may be necessary. In the case of metabolic or other physical disorders such as Crohn’s disease or diabetes, medical treatment is essential.

Treatment of bulimia may also include psychiatric medication. When co-morbid psychiatric disorders, such as anxiety or depression, are present, a psychiatrist may recommend a combination of pharmacological interventions (treatment with medication) in addition to psychotherapy.

CRITERIA AND SYMPTOMS OF BULIMIA
Bulimia typically appears in late adolescence or early adulthood. The majority of those affected are women. However, it is believed that more boys and men suffer from the disorder than statistics indicate. Their cases often go unreported, as men are less likely than women to seek medical help for psychological issues.

  • The primary symptom of bulimia is recurring episodes of binge eating. During these episodes, individuals consume significantly more food in a short time than most people would in a similar situation. They often feel they can’t stop eating or control what or how much they eat.
  • Fear of weight gain leads to inappropriate compensatory behaviors. People with bulimia often induce vomiting, eat irregularly, or starve themselves. Many engage in excessive exercise or misuse medications such as appetite suppressants, laxatives, or diuretics.
  • A cycle of strict dieting and binge eating develops. Many impose rigid dietary rules they can’t maintain long-term. Fasting often triggers intense hunger, leading to new binge episodes, which, in turn, heighten the urge to compensate to avoid weight gain.
  • Self-esteem is heavily tied to body image. People with bulimia are often dissatisfied with their body weight and shape. They frequently desire a weight below what is considered healthy.
  • Bulimia often follows a fluctuating course. Symptoms may disappear for months, followed by phases of pronounced disordered eating behaviors.

Causes and Triggers of Bulimia

Causes and Triggers for Bulimia

Several factors contribute to the development of bulimia, influencing each other. A distinction is made between causes and triggers, although these are not always easily separable. Bulimia arises from a combination of factors that may interact and influence each other. These can be categorized into causes and triggers, though the distinction isn’t always clear.

Causes and Triggers

Bulimia arises from a combination of factors that may interact and influence each other. These can be categorised into causes and triggers, though the distinction isn’t always clear.

Causes

are influences that determine an individual’s susceptibility to the disorder. They can increase the risk of developing bulimia. These include:

• Biological and physical factors, like genetic predisposition or frequent dieting.
• Traumatic experiences, such as violence, abuse, or neglect in childhood.
• Certain personality traits, such as low self-esteem, perfectionism, or excessive concern about appearance, body shape, and weight.
• Family risk factors, like disordered eating habits or a focus on thinness and appearance within the family.
• Societal influences, including the prevalent thin beauty ideal.

Triggers

are specific events or circumstances that can trigger bulimia. These include:

• High stress is caused by events such as separation, the loss of a loved one, a move, or bullying.
• The onset of puberty with its physical changes and growing challenges.
• Physical factors that make dieting more difficult, such as type 1 diabetes or pre-existing obesity.

Negative Health Implications Caused by Bulimia

Bulimia causes psychological and physical harm with mostly severe long-term consequences. Excessive vomiting leads to stomach inflammation (gastritis) and, in extreme cases, even to stomach perforation. Other long-term effects of vomiting are dental damage, oesophagitis (oesophageal inflammation), and inflammation of salivary glands.

Patients suffering from bulimia are typically not underweight; nevertheless, they can suffer of malnutrition. The latter is caused by an imbalanced or deficient diet combined with purging and leads to loss of vitamins (vitamins B12 and D), microelements, electrolytes, and hormonal changes. In consequence, bulimic patients develop heart and kidney problems, hair loss, skin illnesses, and osteoporosis. 

Buimia. Diagnosis and Treatment. Summary

Bulimia nervosa features a cycle of food cravings and compensatory behaviours, such as self-induced vomiting or the use of diuretics or laxatives, sometimes repeated several times a day. People with bulimia nervosa are usually average weight. Although their weight might be within the normal range, they are dissatisfied with their body shape. As a result, they sometimes give up eating altogether: they go hungry or eat irregularly. They often go on diets or skip meals. Affected people get caught in a vicious circle of not eating, food cravings, binge eating, and self-induced vomiting.

The condition is strongly associated with feelings of guilt and shame. This is why this eating disorder is often kept secret and remains hidden for years.
