The “Double Life” of Bulimia Nervosa: Patients’ Perspectives

Tetyana 57 Comments

My psychiatrist once compared my life to Dexter. He said I was living a double life. It was the summer before my final year in undergrad and I was working in a neuroscience lab. Yet things were so bad that at one point I was very close to quitting and doing Day Program treatment. (I didn’t, and things ended up getting better, thankfully.)

This post is going to be more personal than most. One, I can relate well to the topic. Two, I feel that I can give voice to it under my real name. (As opposed to just discuss it abstractly, or anonymously. There’s nothing wrong with being anonymous, but I feel that, for many reasons I am in a position where I don’t feel I have to be anonymous anymore.)

I think this is important because there are a lot of myths that surround eating disorders and … Continue reading →

Will The Real Vegetarian Please Stand Up? – Part 1

Tetyana 12 Comments

When my younger sister first told me she wanted to become a vegetarian, I was worried. My biggest fear was that she would, like I did, develop an eating disorder. In high-school, I didn’t eat meat for roughly 14 months, and though I can’t be sure now of what my reasons were at the time, in retrospect, I do think in large part it was just a convenient way to avoid yet another food group. It was a legitimate reason to restrict my intake.

But is there any evidence that this behaviour (becoming vegetarian as a convenient way to restrict intake) is common among individuals with eating disorders? What is the relationship between dietary restraint, eating disorder symptoms, and vegetarianism? Is vegetarianism a risk factor for developing an eating disorder or do eating disorders lead many to adopt a vegetarian diet as a socially acceptable excuse to avoid eating specific … Continue reading →

Are All Anorexia Nervosa Patients Just Afraid of Being Fat? – Part 2

Tetyana 7 Comments

If you’ve been reading this blog for a while (or literature on this topic) you know the answer is no. I’ve blogged about this before, but I think it is a topic that needs a lot more coverage because the myths that all anorexia nervosa patients are just afraid of being fat, that they lose weight just to be thin, and that thin models are to blame for AN are still very common.

As you’ll see, I am not claiming that this isn’t true for some patients. Instead, what I am claiming is that it is not true for all patients.

And a big personal goal of mine with this blog is to broad the conversation about eating disorders. Let’s get away from stereotypes and painting all anorexia nervosa or bulimia nervosa patients in the same light. Let’s instead have meaningful discussions about research on eating disorders, about … Continue reading →

3 Personality Subtypes in Eating Disorder Patients: Which One Fits You?

Tetyana 10 Comments

Scientists love classifying and categorizing things they study. But it can be a double-edged sword. Classification can lead to new insights about etiology or new treatment methods. But classification can also hamper our understanding. For example, researchers like to classify and study anorexia nervosa and bulimia nervosa as if they are two wholly separate disorders, but clinicians know that most patients fluctuate between diagnoses, and as a result often fall into the eating disorder not otherwise specified (EDNOS) category.

Nonetheless, if we keep in mind that the way in which we classify things can be very artificial and may not necessarily reflect some fundamental truths about the subject matter, we can focus on extracting the insights gained from the classifications.

In the case of eating disorders, classifying patients into subtypes may be useful for developing successful treatment approaches suited for particular patient subgroups.

Previous research on this topic has identified … Continue reading →

Self-Denial, Secrecy and Deliberate Lying in Eating Disorders

Tetyana

I don’t know how many times I’ve said, “I’ve already eaten, thanks,” “No thanks, I’m going be eating later,” or “I’d love to, but I’ve got a stomach ache,” when I actually hadn’t eaten, wasn’t going to eat later, and didn’t have a stomach ache. Why did I do that? Did I realize I had, or was developing, an eating disorder? How long did it take for that realization to click? And once it did, did I stop lying to avoid eating with others or did I do it more?

A lot of questions spring up when you start thinking about secrecy, denial, and lying as it related to eating disorders. And answering these questions by having to remember what you thought when you first began to show signs of your eating disorder is hard. It is hard for many reasons, but one reason is that the we feel about … Continue reading →

Should Anorexia Nervosa Patients Get the Flu Shot?

Tetyana 2 Comments

Is getting the flu shot a good idea if you have anorexia nervosa? Is it safe?

To be honest, I’ve never asked myself that question before. Last year, when I was underweight, I got a flu shot mainly because the laboratory where I am doing my graduate degree is in a hospital–the same hospital that was at the centre of the SARS epidemic in Toronto–and I didn’t want to put patients at risk. Sure, I spent most of my time staring at worms through a microscope (true story) but in the rare event I ventured outside for a coffee, I didn’t want to cough on newborn.

So I was kind of excited to find out the answer when someone asked me this question earlier today on tumblr. As expected, I didn’t find much information, but I did find one relevant paper published online in 2011 by Arne Zastrow and … Continue reading →

Does the Media Cause Eating Disorders? Disordered Eating in Iranian Women: From Tehran to Los Angeles

Tetyana

What is the impact of Western culture on eating disorders? Do images of thin cause eating disorders? I mean, it seems like such a nice and simple hypothesis. It makes intuitive sense: glamorize thin and make thin cool and BAM, everyone wants to be thin. It would be so much easier. Cause? Found. Solution? Easy: ban thin models. Unfortunately (or fortunately for me, since it gives me a lot to blog about) the answer is not that simple.

Just in the last couple of hours, some people who’ve ended up on the SEDs blog have searched:

  • does the media cause eating disorders
  • thin models on tv cause eating disorders to young girls
  • do models influence anorexia
  • ultra thin models causing eating disorders
  • magazine article eating disorders caused by the media
  • and the rare: media doesn’t cause eating disorders

I’m sure most of these search terms lead people to the … Continue reading →

A Study Without a Control Group? Evidence for Enhanced Cognitive Behavioural Therapy for Adults with Anorexia Nervosa

Tetyana 7 Comments

Here’s a quick tip: when a study that purports to find evidence of treatment effectiveness–preliminary or not–doesn’t have a control group (a group that doesn’t undergo treatment but is otherwise similar to the group that does), you should raise your eyebrows. Or shake your head. Or roll your eyes. Whichever you prefer.

Why do we need a control group? If the treatment works, we will see improvement in the patients, so isn’t that evidence enough? Well, no.

[T]he whole idea of an experiment is to identify two identical groups of people and then to manipulate something. One group gets an experimental treatment, and one does not. If the group that gets the treatment (e.g., a drug, exposure to a violent video game) behaves differently than the control group that did not get the treatment, we can attribute the difference to the treatment – but only if we can rest assured

History of Anorexia or Bulimia Nervosa? Are You Putting Your Unborn Child At Risk?

Tetyana 4 Comments

What is the effect of having had an eating disorder on pregnancy? And more specifically, are women who’ve had eating disorders more likely to experience perinatal and delivery complications?

Like with a lot of things, the information out there is mixed. (This is why one study is never enough and replication is crucial.) Early studies seemed to have suggested that women with EDs face an increased risk complications during the last stage of pregnancy and during delivery. On the other hand, subsequent studies done with larger clinical samples didn’t find any major differences between women with and without (a history) of eating disorders.

The authors summarize the current state of knowledge:

In short, the available evidence suggests that both active and past maternal [anorexia nervosa] may be associated with a decreased birth weight and that maternal ED might be associated with pregnancy and postnatal complications. Methodological limitations of previous

Eating Disorders Among Lesbian and Bisexual Women

Tetyana 9 Comments

The hardest part of science blogging is picking an article to blog about. In times when I’m indecisive–when I spend hours sifting through the literature, inevitably creating several draft posts before deciding each article isn’t interesting enough–I turn to the list of topics that have been suggested by readers. The last suggestion I received was “eating disorders in the lesbian community.” It is a great suggestion, but I thought my search wouldn’t turn up much. But, to my surprise, it did turn up some studies.

But please, don’t expect too much: it is not a well-studied area, and most of the data comes from self-reported questionnaires, which are not particularly reliable:

  • First, there’s selection bias: the 50% or so of people who return the surveys could be different in significant ways from the 50% that don’t. For example, in a survey about mental health, perhaps individuals that have
