Energy Expenditure in Anorexia Nervosa Patients

Tetyana 7 Comments

How many calories do patients with anorexia nervosa need to eat to gain a kilo (2.2 lbs)? It seems like a simple question and one that we should have figured out a long time ago, given the importance (err, necessity) of refeeding and weight restoration in recovery from anorexia nervosa.

Unfortunately, research in this area has often led to contradictory results (see Salisbury et al., 1995 and de Zwaan et al., 2002 for reviews). Fortunately, a paper by Stephan Zipfel and colleagues (2013, freely available here) sheds light on one potential cause of the discrepancies.

But first, some definitions:

TDEE stands for total daily energy expenditure. TDEE has three components: resting energy expenditure (REE), dietary-induced thermogenesis (DIT), and activity-induced thermogenesis (AIT). The gold standard for measuring TDEE is through something called the doubly labelled water technique. REE is usually measured through indirect calorimetry. (These techniques were used in this … Continue reading →

Eating Disorders and Irritable Bowel Syndrome

Tetyana 22 Comments

Eating disorder patients commonly complain of gastrointestinal (GI) symptoms including bloating, abdominal pain, and constipation. This is, of course, not surprising. After all, disordered eating behaviours such as self-induced vomiting, laxative abuse, and restriction are bound to have negative effects on the digestive system.

But just how common are GI complaints and functional gastrointestinal disorders (FGIDs) like irritable bowel syndrome among ED patients? And is there more to the relationship than simply ED behaviours causing GI disturbances? Luckily, a growing number of research studies are beginning to shed some light on these questions.

In a study published in 2010, Catherine Boyd and colleagues examined the prevalence of FGIDs among ED patients admitted to a hospital Eating Disorders Unit. They found that out of the respondents (73 in total), 97% had at least one FGID (as evaluated using the Rome II questionnaire). More specifically, on admission, 73% of the … Continue reading →

Enraged by Sounds: Misophonia in Eating Disorder Patients (Clinicians, Listen Up)

Tetyana 19 Comments

Few people would claim to like the sound of chewing, lip smacking, or pen clicking. But while disliking these noises is commonplace, experiencing anxiety, panic and/or rage in response to them–a condition called misophonia (hatred of sound)–is not.

Well, truth be told, we don’t actually know how common it is: Searching “misophonia” in PubMed returns just 14 results. Seven were published in 2013/2014, and only three were published prior to 2010. (Searching “selective sensory sensitivity syndrome,” another name for “misophonia” wasn’t particularly fruitful either.)

Interestingly, the most recent paper on misophonia investigated the phenomenon in eating disorder patients. Timely, I thought, given that a few months ago someone had asked me about this very thing on Tumblr. At the time, I came up with nothing. Now I had something. So I posted it on the SEDs Tumblr. The response was almost immediate (click here to … Continue reading →
