Characteristics of Women with Midlife-Onset Eating Disorders

Tetyana 4 Comments

Since the late 1990’s, Remuda Ranch Program for Eating Disorders has experienced a 400% increase in patients 40 years of age and older, according to the authors of this paper. However, we don’t really know what the similarities and differences are between women who develop eating disorders in adolescence and those who develop their eating disorders in midlife (40-65 years of age).

It has been theorized that EDs in midlife may be triggered by midlife transitions, such as loss of parents, siblings, or children; divorce; traumatic illness; and empty nest syndrome (Harris & Cumella, 2006; Maine & Kelly, 2005; Shellenbarger, 2004). […] Two quantitative studies found a high correlation between the fear of aging and disordered eating in older populations (Gupta, 1995; Lewis & Cachelin, 2001).

In this paper, Edward Cumella and Zina Kally present a summary of 50 women who first developed eating disorders at the age of 40 … Continue reading →

Can Puberty Affect the Development of Eating Disorders?

Tetyana 3 Comments

Eating disorders typically begin in adolescence. One common explanation for this is that during adolescence females are increasingly exposed to the media, thin models, and dieting. While this is probably true to some extent, it doesn’t explain why the rates of eating disorders are quite low despite the high levels of exposure to thin models in the media. Out of 100 girls, only a handful develop eating disorders, yet all of them are exposed to the same magazines and TV shows.

This means there must be some other factors that differ between this group of girls. One hypothesis is that hormonal changes during puberty may modulate the genetic risk factors for eating disorders. These changes may “turn on” genes that predispose individuals to eating disorders. Previous research has shown that genetic factors modulate disordered eating (eating disorders have a high heritability), but how? What are the mechanisms of this modulation?… Continue reading →

Weight Restored, Eating Well, But No Menses in Sight? Huh?

Tetyana 5 Comments

It is to be expected that the Diagnostic and Statistical Manual of Mental Disorders, at least when it comes to anorexia nervosa, relies heavily on measures that are hard to quantify and measure objectively. The big exception is amenorrhea: the absence of menses (commonly known as “periods”) for three consecutive months. As I’ve mentioned before, this criterion will be removed from the next edition of the DSM, thankfully. But for now, it is still there.

Perhaps because it is easy to measure objectively, the resumption of menses is often taken to be a marker of “health” and “recovery.”  It is a common goal in treatment for patients to reach a “menstruating weight.”

[Conversely, not losing one’s menstrual cycle is often perceived by the patient that they are not “sick enough.” Their eating disorder is not legitimate because clearly they are eating enough for their menstrual cycle to continue, and thus … 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 →

Think You Are Not “Sick Enough” Because You Didn’t Lose Your Period? Read This.

Tetyana 1 Comment

Anonymous asked, “I’ve never lost my period. Weight restored I am naturally thin, but even at a BMI of 15 or so I always got my period (although it wasn’t always regularly). This makes me feel like I’m not actually sick because I hear about everyone losing their period.”

eatruncats replied: “To the anon who asked about losing periods: For all the times she worries about not being sick enough because she never lost her period, there are people who lost their periods at BMIs of 18, 19, and 20 who worry about not being sick enough because they never got to a BMI of 15. If you have an eating disorder, you are “sick enough.” Period.“

As it stands now, amenorrhea–or the loss of three consecutive menstrual cycles–is a diagnostic criterion for anorexia nervosa. Individuals who have not lost their periods are diagnosed with eating disorder not … Continue reading →

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

How Common Are Eating Disorders? Incidence, Prevalence and Mortality Rates

Tetyana 1 Comment

Six month of blogging and I have yet to do a proper post on the prevalence of eating disorders. I think it is about time. I see all sorts of numbers thrown around, often depending on the purpose of the article and the author’s bias. Is it 1 in 1000, 1 in 100, 1 in 20 or maybe even 1 in 2? Who is right?

Well, it is a tricky question to answer.

The number depends on how the particular study was conducted. Here are some factors that may influence the final rates: the population being studied, the sample size, the definition of eating disorder, the methods used by researchers to identify and screen for individuals with eating disorders, the number of years over which data is collected, and so on. In other words, a lot! That’s why in order to get a better sense of the true numbers, I … Continue reading →

Diabulimia: Disordered Eating in Type 1 Diabetic Patients

Tetyana 15 Comments

Type 1 diabetes mellitus (DMT1) is a lifelong chronic disorder that occurs when the body is unable to produce enough insulin – a hormone that is required for carbohydrate metabolism. Patients must learn to manage their disorder by monitoring their blood sugar levels on a regular basis, carefully selecting the foods they eat and how much exercise they do. Before insulin was extracted and purified (at University of Toronto!), type 1 diabetes, which usually occurs in children and adolescents, would very quickly lead to death – the body, unable to take in the very thing it needs to survive.

Unfortunately,  patients with type 1 diabetes are at increased risk of developing eating disorders or disordered eating behaviours. Diabulimia refers to an eating disorder in patients with DMT1 who reduce or skip insulin doses to reduce their weight.

The exact prevalence rates vary study by study, depending on the population sample, … Continue reading →

Medical Complications in Patients with Eating Disorders: An ER Perspective

Tetyana 7 Comments

A healthy-looking young woman comes into the emergency room complaining of lightheadedness, dizziness, tiredness, dehydration and constipation. She tells you she doesn’t know what’s wrong, but what she is not telling you is that she has an eating disorder. How do you find out? More importantly, how do you avoid complications that may arise from using conventional treatments for patients without eating disorders?

I often come across questions posted on websites and forums asking if others have experienced a particular symptom, what could be causing it and whether going to the hospital is necessary. I am not a physician, not training to be a physician and not doing research in anything directly relevant to medicine or health. Moreover, I always use caution when answering questions online – the best advice is to go see a doctor (but of course, that’s not always possible, unfortunately).

My goal with this post … Continue reading →

What You Should Know About Anorexia Nervosa and Bone Health

Tetyana 7 Comments

Recovery from an eating disorder is really hard. Unfortunately, the negative effects of that occur as a result of the eating disorder often persist long after recovery. It is hard to undo the mental and psychological aspects of anorexia or bulimia nervosa, but it may be just as hard, if not impossible, to undo the damage done to body.

What are some of the long-term health effects of eating disorders? What do patients with eating disorders – recovered or not – have to live with, for years, often decades, after recovery?

A really common consequence of anorexia nervosa is osteoporosis: thinning of bone tissue and loss of bone density. Unlike delayed gastric emptying – another consequence of EDs – which can make every meal a nightmare (particularly for someone recovering from an eating disorder): acid reflux, stomach pain and abdominal bloating are just some of the symptoms, bone density … Continue reading →
