The frequencies of various forms of eating-related behaviour (such as vomiting and laxative abuse) are reported for a series of non-anorectic bulimia patients seen for evaluation in an eating disorders clinic. The results of serum electrolyte, glucose and other screening tests in these patients are presented. Electrolyte abnormalities were found in 82 of the 168 patients (48.8%) who were diagnosed as having either bulimia or atypical eating disorder. The most common abnormality was metabolic alkalosis (27.4%); hypochloremia (23.8%) and hypokalemia (13.7%) were also commonly seen. No significant blood sugar abnormalities were encountered. An elevated serum amylase level was found to be associated with frequent binge-eating and vomiting behaviour. The pathophysiology of electrolyte abnormalities in this patient group is briefly reviewed.

Bulimarexia, an eating disorder that is characterized by binge eating followed by self-induced vomiting or abuse of cathartic or diuretic drugs, has been defined as both a sequela of anorexia nervosa and a distinct eating disorder. In this review the presentation, prevalence, and complications of the various eating disorders--anorexia nervosa, pica, rumination disorder of infancy, and bulimia/bulimarexia--are discussed. Detailed attention is given to the potential medical hazards of bulimarexia. These hazards may be categorized according to the organ system affected or the individual behavioral components of bulimarexia. Because bulimarexia is commonly practiced in secrecy, its presentation may be in the form of one of its medical complications. Therefore, physicians must know the behavioral components of bulimarexia and its potential medical hazards. Optimal care of these patients requires collaborative efforts from a physician and behavioral therapist.

This study reports the results of a biochemical investigation of 80 eating disorder patients and results of an endocrinological investigation of 20 subjects. Of the 80 subjects studied, 22 suffered from anorexia nervosa and 51 were diagnosed as having bulimia. These patient's results were compared to those of 30 control subjects. The eating disorder patients had significantly higher levels of total CO2 calcium, alanine aminotransferase and cholesterol, and significantly lower levels of potassium, chloride and phosphate in the plasma. Hypokalaemia was strongly associated with self-induced vomiting and laxative abuse. Hypercholesterolaemia occurred most commonly in anorexia nervosa patients. Preliminary endocrinological results suggest decreased gonadotrophin levels are associated with binge eating and self-induced vomiting and laxative abuse, as well as with low weight. We feel eating disorder patients should be interviewed and examined by a physician with an interest in this area. Appropriate investigations should be ordered. The physician should also undertake counseling about the short- and long-term sequelae of disordered eating.

Bulimia is an eating disorder characterized by the ingestion of large amounts of food, usually followed by self-induced vomiting or laxative abuse. Although sometimes a symptom of obesity or anorexia nervosa, bulimia is often associated with borderline weight and nutritional status and thus may be difficult to detect. Since secrecy and shame accompany this syndrome, patients are reluctant to seek treatment. We present ten diagnostic clues for identifying bulimic patients: (1) preoccupation with weight, (2) gastrointestinal complaints, (3) dental and oropharyngeal changes, (4) salivary gland enlargement, (5) edema and bloating, (6) amenorrhea, (7) dermatologic complaints, (8) substance abuse, (9) laboratory changes, and (10) serious consequences. A case study illustrates the major features of the disorder and its treatment.

The prevalence of the syndromes bulimia and bulimia nervosa is not known. Although existing epidemiological studies have produced somewhat conflicting findings, it appears likely that these syndromes constitute a significant source of psychiatric morbidity. It is interesting to note that prior to 1980 there appear to have been few patients who fulfil diagnostic criteria for these syndromes, whereas since then the number of such patients seems to have greatly increased. Whilst it is possible that the recent publicity may have engendered new cases by suggesting that self-induced vomiting is an effective means of weight control, there are two other likely explanations for the increase. First, the publicity may have helped people with these conditions divulge their eating problems to doctors. Second, doctors may have been alerted to the fact that people with a normal body weight may nevertheless have an eating disorder which requires a specialist's help. If these explanations are correct, the upsurge in referrals may be a short-lived phenomenon during which existing cases of varying duration will come to attention. Thereafter, it would be predicted that the referral rate will decline to a level which more accurately reflects the incidence of the two conditions (22). The emergence of these syndromes is not simply of theoretical interest. They pose a challenging therapeutic problem which has necessitated the development of specific psychological approaches to their treatment. However, before any treatment for bulimia can be advocated, its use should be supported by data from controlled outcome studies in which changes in each facet of the condition are assessed including patients' eating habits, moods, and most importantly, their attitudes to their weight and shape. As has been discussed, behavioural improvement is likely to be short-lived unless it is accompanied by significant attitude change.

Six hundred and twenty women who were currently practising self-induced vomiting to control their weight were identified with the help of a women's magazine. Nineteen women (3.1%) fulfilled diagnostic criteria for anorexia nervosa. Of the remainder, 499 (83.0%) fulfilled diagnostic criteria for bulimia nervosa, a recently described eating disorder. Of these, 56.1% practised self-induced vomiting at least once daily; the mean duration of vomiting was 4.5 years. Most women were of normal body weight. On standardised measures, 68.1% of women showed pronounced psychiatric morbidity and 89% had profoundly disturbed attitudes to food and eating. 56.4% thought they definitely needed medical help, though only 30.1% had ever discussed any aspect of their eating difficulties with a doctor. This study highlights the secrecy that surrounds bulimia nervosa and suggests that it is an important undetected source of psychiatric morbidity.

Anorexia nervosa and related eating disorders are rare in non-western cultures. In India the information regarding these disorders is very limited. The authors describe five cases of young women who chiefly presented with refusal to eat, persistent vomiting, marked weight loss, amenorrhea and other somatic symptoms. They did not show overactivity or disturbances in body image seen characteristically in anorexia nervosa. Though finally diagnosed and treated as cases of eating disorder, they presented considerable difficulty in diagnosis. The paper discusses the reasons for the seeming rarity of anorexia nervosa in India and sociocultural reasons for its atypical presentation.

Bulimia nervosa is a psychological compulsive eating disorder that appears to be affecting a growing number of young women. It is characterized by repeated episodes of binge-eating followed by vomiting or some other purging behavior. Bulimia is accompanied by a number of physiological disturbances, some of which occur in the oral cavity. The present article reviews the major characteristics of bulimia nervosa, and describes the most significant oral manifestations of this disorder along with their reported incidences and etiologies.

Low ego strength is theoretically thought of as causing difficulties in interpersonal relations and leading to the development of psychiatric symptomatology. Patients with bulimia nervosa were previously shown to have low ego strength and were studied to investigate whether gains in ego strength occur over time and are associated with improvement in symptoms. The average patient had an ego strength at a borderline level at index and at a neurotic level 6 years later. Less positive change in ego strength was associated with a low initial Eating Disorder Inventory (EDI) Symptom score a long Time in Treatment, and having been referred for specialist care. Positive changers significantly more often stopped vomiting/abusing laxatives and showed several non-significant tendencies to improve in other symptomatic aspects as well. Several methodological caveats are discussed, but these findings may contribute to the identification of mechanisms whereby long-term improvement occurs in bulimia nervosa.

Anorexia and bulimia nervosa (the eating disorders) are potentially life threatening and are becoming more prevalent. This paper reviews the effects of these disorders on dental erosion and reports a study to assess the effects of the eating disorders on the erosion of teeth relating the severity of erosion to factors such as the frequency of self-induced vomiting (SIV). One hundred and twenty-two eating disorder patients and an equal number of age, sex, and social class matched controls were studied. The study population was divided into subgroups according to the eating disorder. All the subgroups had significantly more abnormal toothwear than the controls (P < 0.005), with the differences being most marked in the SIV groups. Further analysis did not find any consistent relationships to the frequency or duration of SIV.
