Please gave me a respponse to this classmate Jonathan Ruiz Sep 26 11:19pm Reply from Jonathan Ruiz The three common food disorders are Anorexia Nervosa, Bulimia Nervosa, and Binge-Eating Disorder. They are different because as conveyed from the textbook, Anorexia Nervosa, also known as the starving disease, is described as a type of extreme food restriction and does not at all want to gain weight leading to being underweight with many health problems. Bulimia Nervosa involves binging which can be followed by vomiting or lots of exercise. For Binge-Eating Disorder, it was described by a lot of binging without purging behaviors which made them overweight or obese. Some of the common similarities through these disorders include disordered eating, body dissatisfaction, and mental issues. They also happen at the same time with anxiety, depression, and obsessive-compulsive disorder, which shows a strong psychological connection is involved. There are many causes of this that include involvement of genetics, social issues, and brain dysfunction. There is much involvement of genetics as concluded from the textbook, Anorexia Nervosa is shown to be 56% heritable, Bulimia Nervosa 83% heritable. On physiological issues, there is changed anatomy and physiology of the brain especially in the areas responsible for reward, control, and body awareness. Neurotransmitter dysregulation happens with dopamine dysregulation. Serotonin, dopamine, and cannabinoidsplay a big part in the eating disorders problems. It’s used as a normal way to live with a normal diet as something rewarding but can be detrimental with an extreme diet. The textbook mentions that serotonin regulates mood and hunger normally. Serotonin activity is changed in anorexia and bulimia since both disorders are described by anxiety and harm avoidance. Low levels of serotonin are found in people with binge-eating disorder though binge eating sometimes elevates serotonin to raise mood. Dopamine is involved in eating with either a reward or motivation, as illustrated by reduced activity in anorexia and increased activity in bulimia and binge eating disorder. Dysregulation of cannabinoids may contribute to food pleasure of eating in anorexia or enhanced food craving seen in the disorders. This shows the importance of neurotransmitters to change eating behaviors hooked from anxiety and avoidance of eating and dopamine being a really important reward and impulsive in eating.
