1INTRODUCTION TO APPLIED RESEARCH
As per the Diagnostic and Statistical Manual of Mental Disorders (DSM), the two major
type of eating disorders are Anorexia nervosa and the Bulimia nervosa. These eating disorders
are now termed as the eating disorders which after development of DSM 5 system, is termed as
the Feeling and eating disorders (Mustelin et al., 2016). Anorexia disorder is the condition in
which affected people are unable to maintain their body weight and improper balance between
their height weight and body mass is observed which leads to distorted body shape. People
affected with this disorder complaints about abdominal pain or constipation to avoid eating and
psychologically avoids eating in public, during mealtime that causes weight loss (Hamatani et
al., 2016). On the other hand, Bulimia nervosa is characterized by severe eating disorder in
which the tendency of binge eating increases and to compensate this, self-induced vomiting is
also observed. Individuals affected with this disorder deliberately uses laxatives, and are unaware
of their excessive weight gains (Lavender et al., 2016).
Several socio-cultural factor can induce the eating disorder in people. Factors such as
cultural custom, life style, environmental condition and socio-economic condition can lead to
eating disorder. Pressure of such socio-cultural factors could lead to excessive stress due to
which the person may develop the eating disorder (Lavender et al., 2016). Further, the stress
associated to thee condition could affect the genesis and management related factors in
individuals affected with eating disorders thereby increasing complication associated with this
(Mustelin et al., 2016). Several traditions, defines thinner and taller body as an ideal body shape
and hence, teenagers, are affected with the custom and due to starving, they become affected
with eating disorders (Hamatani et al., 2016).

2INTRODUCTION TO APPLIED RESEARCH
Binge eating disorder is associated with dieting and resulting weight loss that increases
the tendency of binge eating among people affected with this disorder. Hence, presence of
anorexia nervosa could occur due to the presence of Binge eating disorder (Dakanalis et al.,
2017). On the other hand, people are affected with bulimia nervosa due to a variety of stressors
that could induce them to consume more food under stress and then make them prone to self-
induced vomiting. Therefore, these factors help to differentiate between binge eating disorder
and bulimia nervosa (Lavender et al., 2016).
