Eating disorders in the DSM-5
Anorexia nervosa
Bulimia nervosa
Binge-
eating disorder
Preoccupation with weight and body image resulting in low food absorption → low BMI (BMI 18.5)
Restrictive: patient severely limits food intake
Binge eating/purging: food intake followed by compensation (vomit, laxative/diuretic, and/or exercise)
Coexist with perfectionism; depression
Associated medical issues: starvation, osteoporosis → fractures, amenorrhea, anemia, electrolyte disturbances (refeeding syndrome, hypophosphatemia), hypothyroidism (euthyroid sick syndrome) with low T3/T4 but low/nl TSH, IUGR/prematurity in pregnancy,
Treat with psychotherapy, low dose olanzapine (SSRIs ineffective unlike bulimia)
Anorexia nervosa
Bulimia nervosa

eating disorder
Anorexia nervosa
Binge eating followed by compensatory behavior:
Purge: vomit, laxative, diuretic
Teeth and enamel erosion, esophageal tears, parotitis, thickened knuckles
Non-purge: exercise or diet
Patients are normal weight or overweight (BMI 18.5)
Treat with psychotherapy and SSRIs (fluoxetine); bupropion is contraindicated
Anorexia nervosa
Bulimia nervosa
Binge-
eating disorder
Bulimia nervosa
The erosion on the lower teeth was caused by bulimia. For comparison, the upper teeth were restored with porcelain veneers.
Binge eating WITHOUT compensatory behavior
Therefore does not fit qualifications of bulimia
At least three of the following:
Eating quickly
Eating alone out of embarrassment
Eating until uncomfortably full
Binge eating when not hungry
Feelings of guilt/depression/disgust after eating
Patients are often overweight / obese and suffer from metabolic syndrome, cardiovascular disease, and diabetes
Treatment: psychotherapy, strict diet/exercise, stimulants and orlistat (pancreatic lipase inhibitor) may help

This was great but BMI is meaningless if a person is athletic/muscular, I don’t know why it continues to be used, especially in these scenarios that include people who exercise a lot.

[letizzietta]

It's very well done, but as I actually have an eating disorder (binge eating) I would like to underline that it's actually not good/useful to have a strict diet, as it could lead to be too much hungry and to binge again. Of course, if you are used to eat a lot (even during meals) a normal diet would lead you to be hungry, more than the usual, but it shouldn't be excessicevely strict unless you are severely obese and need to lose lots of kg quickly for health reasons. I have a diet of almost 1500kcal daily (and it's a pretty normal kcal intake for a healthy woman) and I still am losing weight. Apart from it the video is well done.

Is there a specific reason why body fat percentage is not used instead of bmi?

[waldmann]

I'm gaining weight and losing it again so my bmi is changing between above and under 18.5 all the time. I restrict and binge so bulimia and anorexia would fit both with makes it even harder to be diagnosed and see a the problem

Some things people can’t handle (not being rude):
Not all anorexics are thin.
There is no anorexia body type.
People with anorexia can purge / throw up their food.
People with eating disorders can show symptoms of multiple eating disorders without it being EDNOS.
Anorexics and bulimics do eat. (Surprise surprise)
Not every anorexic is underweight.
Not every binge eater is overweight.
Anorexics can binge.
Bulimics can be underweight too.
Bulimia, BED, pica, EDNOS and other eating disorders can be just as hard to treat as anorexia.
Anorexia isn’t the only eating disorder.

- This comment isn’t directed to anyone.

Your videos are clear and the visual representation is also phenomenal. Keep at it!

[kilees]

olanzapine actually caused my eating disorder, it made me gain a LOT of weight, which made me hate my body and then i took extreme measures to lose the weight

[cynthiajohnston]

I am curious about your recommendation to "obviously" recommend a strict diet and exercise for someone with BED. I specialize in the treatment of EDs and I would almost never recommend a strict diet.

Great and consistent summarization skills in these videos 📹 👏

I've had periods where I did binge eating and compensated with fasting. My weight stays within a 10 pound range. In my experience, binge eating comes from subconscious 'food anxiety', so basically the perception that food may be scarce later, therefore I need to binge. I cured my binge eating by always satisfying my hunger cues, and surrounding myself with plenty of food, including possible trigger foods. I've trained my subconscious to relieve itself of food anxiety and my binging episodes have dropped to 1 or 2 per month, as opposed to 2-4 times per week when I was at my worst. I still occasionally indulge in overeating, but there is no guilt or need for compensatory behavior.

Binge eating is about a vicious cycle of binging and guilt and compensation. The cure is to give your body what it needs and take away the anxiety of food scarcity, and that means including trigger foods in your life. Once your subconscious learns that there is no shortage of food, and that triggers foods are 100% okay to eat, binging behavior goes away effortlessly.

Amazing amazing amazing.
U jst made life easier.

[ddlovogue]

So my question would be, the only difference between the binge/purge subtype of anorexia, and bulimia, is the BMI?

[souleaterevans]

What about people who flip between binge eating like one day a week and then going barely any thing the other dayd

[maidaya.a]

I'm a binge eater :( :( :( :(
I'm the first and last 2 reasons but I'm not overweight. You don't have to be overweight to binge eat ppl need to get that right!!
I've been fasting for 2 days now to control my eating.

Also can someone tell me the difference between fasting and anorexia

[khajanawaz]

Wow ! What a wonderful video, really you made medicine easy! 🙏
But just 50 views 😐

[ronishadoty]

This is great and gave me a better understanding I enjoyed the chart

[JC-ezmj]

Does Restrictive Anorexia include binge eating as well?

[mansakumar]

Furthermore, one can also have bulimia and be underweight

[izzydandrea]

can you have binge eating disorder and be a normal weight

[whocares-sqzh]

What does starving yourself after eating a large meal mean?
