This is poetry! Please never stop doing this videos, I love them, they are really interesting.
Great video! I'm a biochemist specialicing in neuroscience, also I'm an anorexic in recovery. Recently i've been taking antidipressants that are blockers of serotonin recaptation increasing the neurotranmistter concentration in instra-synaptic sites. This pharmac is used for treating depression and general anxiety disorder, pathologies often associated with eating disorders, that I also suffer. I was wondering how this is compatible with the increased serotonin activity of anorexic brains, and why they prescribe this drugs to patients with eating disorders. Thank you very much! :)
You should probably update to say the eating disorder with the highest mortality rate isn't actually anorexia. It's a subset of bulimia known as diabulimia where people with type one diabetes purposefully manipulate their insulin intake to lose weight. If you can't absorb carbs, your body finds energy else where. Mostly in stored fats and muscle mass. This has the side effect that diabetics aren't taking their medication and dying.
Your Wayward Destiny I find it so odd that opiate or alcohol addiction doesn’t take top spot.
@@janeadelaidelennox7193 While substance abuse will eventually lead to death if you continue over a long period of time, usually it affects some organs more than others. Malnutrition affects every organ system in your body. A slow but constant decay from head to toe which is not easy to recognize or acknowledge. When you take away the core building blocks of your organs - essential vitamins, fats, ions, salts, protein, and carbohydrates, your body has no where to obtain energy other than itself. That is the start of muscle atrophy and organ failure. If your GI tract is damaged, absorption and secretion of water, sodium, and potassium is affected. A major upset in electrolytes can lead to sudden cardiac arrest (no electrical signals from the brain to beat). Every neuron is covered with a myelin sheath consisting of fat, so the size of your brain actually shrinks and MRI scans have found holes in the brain from severe eating disorders. Not only is it just eating away at your organs, but it is harder for the body to heal and recover these damages, as you’re not supplying it. Doctors now announce death after both the stop of functioning in the heart and brain, eating disorders are a fast track to both
Diabulimia is not officially medically recognised
@@catboy_official And? It's officially diagnosed as bulimia, then. Meaning anorexia is still not on the top given how deadly this specific kind of purging is. If you require the medical stamp of approval to recognize a fatality problem, all you've done is roll the other bulimia related deaths into a portion of the population that has an insanely high kill rate making bulimia more fatal appearing instead of letting the stats reflect a marked distinction. The majority of the recovered bulimic population survives, but is usually horribly wrapped by disability, which is its own set of horrors.
Wow! great video you actually talk about what eating disorders are really are
Trauma has a lot to do with eating disorders
Yes
Thanks!!
EDs are not really about food or numbers. It’s a stress control method. In Anorexia, yes there is a definite stress control. Also a lot of ppl with Eating Disorders at some point had over controlling parents, or too conservative parents who didn’t take their emotional needs into consideration, or didn’t know how cuz that’s the way they are. Not growing up getting to experience normal choice options, executive functions that involve what it feels like to chose things for yourself!!
Bulimia defin has dopamine dysfunction. For me, in my past bulimia had zero to do with wanting to change the shape of my body, as the bulimia made me get fatter and kidney damage. It was stress relief, and from having emotional needs neglected as a child.
Thank you for this comment. I've suffered from an eating disorder for more than half my life (20 years now) and your comment puts into words feelings I've felt all my life but could never express. It's not like I've never heard or read or been told similar things before but it's the words you've chosen. They brought tears to my eyes to be able to finally find the words for how I feel.
What's the solution to Binge eating then? It's true that restricting your calory intake you can alleviate your symptoms, but this doesn't work in the long term as it leads to further binges. For people with binge eating is also difficult eating in general: they struggle to restrict their food to the portion selected because ''addicted'' to food in general, even more if they live alone. Good video anyway, thanks!
keto can work
Find the root cause...what is triggering u to wanna eat so much and so unhealthily
Claudia- I have found that touch as in connecting to others physically - bodywork and massage -
Helps curb that seeming impossible need to fill the emptiness
Skin hunger is real
I firmly believe many people with BED actually have severe insulin resistance. They binge because much of their cells are starved for glucose. Testing and treating IR has helped many folks.
Food addiction is like every other addiction in general. U do it to comfort yourself, emotional regulation and dopamine hit. Soo...you gotta do internal work and gain awareness about your emotional mental state. Try to find other alternatives to get the dopamine, hormones etc
Did you see the short videos on 'The Doctors' UA-cam channel this week? They had a doctor who was interviewed on the minds of killers. They discuss the limbic system. I wonder if there are any similarities in terms of what you see with brain scans?
Ok, I work from ICD-10, not DSM-5, but I still can't find anything that supports that sufferers from ANY eating disorder may become "anti social", no evidence or even anecdotes. Did you mean "Asocial"? "Withdrawn"?
Only with a dual diagnoses patient have I seen or heard about this combination of "anti social" and "eating disordered".
Super
Ah man this is all great and all... but where is the practice value?
Bonjour quelqu'un pourrait-il me donner le nom de la personne qui explique le processus dans la video. Je dois réaliser un travail sur cette vidéo pour mon cours de biologie et le nom de l auteur est indispensable . Un grand merci
I don’t find food to be rewarding.
. Very good information. One question. Could music help on eating disorders treatment .l Im Dr Cybelle University Federal of Minas Gerais Brazil
Great video, iv just subscribed t our channel :) Are you a neuroscientist?
I dont have a doctorate, but spent several years at neuroscience centre in canada. I work in health science now. :)
Great :)
you spelled bulimia wrong lmao
So I did. Thx for letting me know
