The field of eating disorder research is continually evolving, and treatments are being developed and refined based on these discoveries. Given the complex nature of eating disorders, it is not surprising that the factors that contribute to these diseases are multifaceted.
There is not one single cause responsible for the formation and development of an eating disorder, but rather, an accumulation of several possible compounding factors that each play a role in the development and continuation of these diseases. These factors can be biological, sociological, emotional, environmental, etc.
One factor frequently investigated by researchers is the biological component of eating disorders. Many have pondered and theorized what mechanisms occur in the human body, specifically the brain, that can make an individual susceptible to developing anorexia, bulimia or binge eating disorder. Studies are currently underway that are examining potential contributing factors of an eating disorder, such as genetics, hormones, and neurobiology.
Neurobiology and brain research, as it pertains to eating disorders in particular, is becoming an increasingly promising area of eating disorder study. Researchers are uncovering new evidence that demonstrates how brain pathways function differently in individuals with eating disorders. Other research studies in this field have shown how both appetite and energy expenditure are regulated by a highly complex network of nerve cells called neuropeptides.
These discoveries and research efforts in neurobiology are important to women and men suffering from eating disorders because health care professionals are gaining a better understanding as to what can be done to effectively treat these conditions. These findings also validate that eating disorders are real diseases that require treatment.
Because of the stigma and misperceptions surrounding eating disorders, many people may not receive the help and support they need. Understanding the possible biological connections with eating disorders brings these disorders into greater light: Eating disorders are not simply a fabrication of one’s imagination or a desire to be thin – they are serious, life-threatening illnesses.
Several individuals are making great strides in neurobiology research as they continue to conduct studies that investigate eating disorders in a valuable perspective. Some of these research investigators at the forefront of this field include Dr. Daniel Krawczyk, associate professor at the Center for BrainHealth at the University of Texas, Dr. Carrie McAdams, assistant psychiatry professor at UT Southwestern Medical Center, and Dr. Walter Kaye, Director of University of California San Diego Eating Disorder Program.
Dr. Krawczyk and Dr. McAdams recently published a study in the journal, Social Cognitive and Affective Neuroscience, which showed that women with anorexia nervosa have different brain activity than those women without the eating disorder .
They are currently working on comparing how brain pathways function in currently ill and fully recovered individuals that have had anorexia nervosa, in the hopes of studying whether changes in these brain regions can be connected with recovery.
Dr. Kaye, who has authored more than 300 articles and publications, has made considerable progress in understanding the brain circuits that may contribute to symptoms such as altered body image and disturbed appetite regulation. His findings, which were published in the American Journal of Psychiatry, are leading to a new understanding of why individuals suffer with eating disorders, as well as important clues necessary for developing more effectual treatments .
Understanding the causes, effects, and treatments of eating disorders are indeed complex; however, progressions in research are shedding light on these once misunderstood diseases, answering intricate questions, and bringing hope to eating disorder sufferers with promising outcomes.

About the author:
Jacquelyn Ekern, MS, LPC founded Eating Disorder Hope in 2005, driven by a profound desire to help those struggling with anorexia, bulimia and binge-eating disorder. This passion resulted from her battle with, and recovery from, an eating disorder. As president, Jacquelyn manages Ekern Enterprises, Inc. and the Eating Disorder Hope website. In addition, she is a fully licensed therapist with a closed private counseling practice specializing in the treatment of eating disorders.
Jacquelyn has a Bachelor of Science in Human Services degree from The University of Phoenix and a Masters degree in Counseling/Psychology, from Capella University. She has extensive experience in the eating disorder field including advanced education in psychology, participation, and contributions to additional eating disorder groups, symposiums, and professional associations. She is a member of the National Eating Disorder Association (NEDA), Academy of Eating Disorders (AED), the Eating Disorders Coalition (EDC) and the International Association of Eating Disorder Professionals (iaedp).
Jacquelyn enjoys art, working out, walking her golden retriever “Whisky”, reading, painting and time with family.
Although Eating Disorder Hope was founded by Jacquelyn Ekern, this organization would not be possible without support from our generous sponsors.
The opinions and views of our guest contributors are shared to provide a broad perspective of eating disorders. These are not necessarily the views of Eating Disorder Hope, but an effort to offer a discussion of various issues by different concerned individuals.
We at Eating Disorder Hope understand that eating disorders result from a combination of environmental and genetic factors. If you or a loved one are suffering from an eating disorder, please know that there is hope for you, and seek immediate professional help.
