Binge-eating disorder

While the level of associated psychopathology in BED is generally less than that seen in bulimia nervosa or anorexia nervosa, depression and anxiety are often present. According to some, making the diagnosis can 

Patients with BED tend to have a greater degree of dissatisfaction with their body image than those with uncomplicated obesity and have lower self-esteem. They show less dietary restraint than patients with bulimia nervosa, and their eating behaviour has been described as more chaotic (Grilo 2002). 

Serum leptin concentrations in BED obese patients were found to be higher than in non-binge-eating obese patients (Adami et al. 2002). This indicates that binge eating behaviour is not triggered by a low plasma leptin level. 

Binge eating is strongly associated with being obese (see next section) and the factors which promote obesity (see Chapter 8) can also be seen to be linked to binge eating. 

While heritability is an important factor in the aetiology of BED, it is less pronounced than for obesity and there seems to be only modest overlap in the genetic risk factors that increase liability to each condition (Bu-lik et al. 2003). According to a large-scale Norwegian twin study, bingeeating appears to be equally heritable in males and females (Reichbom-Kjennerud et al. 2003).

Near the end of the last paragraph, the passage indicates that binge-eating disorder patients experience high blood pressure. 

See the second sentence of the sixth paragraph. If as many as one-third of the binge-eating disorder population are men, it stands to reason that up to two-thirds are younger women, given that we have learned that about 90% of all eating disorder sufferers are adolescent and young adult women. 

When is medication indicated in the treatment of psychiatric illness There is no short answer to this question. At one end of the continuum, patients with schizophrenia and other psychotic disorders, bipolar disorder, and severe major depressive disorder should always be considered candidates for pharmacotherapy, and neglecting to use medication, or at least discuss the use of medication with these patients, fails to adhere to the current standard of mental health care. Less severe depressive disorders, many anxiety disorders, and binge eating disorders can respond to psychotherapy and/or pharmacotherapy, and different therapies can target distinct symptom complexes in these situations. Finally, at the opposite end of the spectrum, adjustment disorders, specific phobias, or grief reactions should generally be treated with psychotherapy alone. 

Poor Timing of Neurotransmission. The activity of some brain circuits, like the secretion of certain hormones, varies at certain times of the day. Called circadian rhythms, the timing of these rhythms may be disrupted in some illnesses. Examples include sleep disorders such as insomnia and narcolepsy, as well as other conditions such as nighttime binge-eating disorder. 

The current SSRIs in the United States inclnde fluoxetine, fluvoxamine, sertraline (Zoloft), paroxetine (Paxil), citalopram (Celexa), and escitalopram (Lexapro). All effectively treat major depression. In addition, one or more of the SSRIs has been shown effective in the treatment of dysthymic disorder, the depressive phase of bipolar disorder, premenstrual dysphoric disorder, panic disorder, social phobia, obsessive-compnlsive disorder, bnlimia nervosa, and binge-eating disorder.

Although these disorders are more common in adolescent girls or young women, 5% to 15% of anorexia nervosa and bulimia nervosa and approximately 40% of binge-eating disorders occur in boys and men (498). 

In a Wesleyan University study of binge eating disorder (BED) published in 2000, researchers found that African-American women with the disorder reported laxative and diuretic abuse more frequently than white women. However, BED was considered a significant health problem in both racial groups.
