Anorexia Nervosa and Bulimia Nervosa
Definition
Anorexia Nervosa is a psychological disease in the form of deliberate starvation due to body image disturbances, excessive fear and irrational about weight gain. (Kimberly, 2011)
Anorexia Nervosa is a food disorder characterized by voluntary hunger and stress from doing exercises that involve psychological, sociological, physiological. (Arif Muttaqin, 2010)
According to the National Eating Disorders Association (NEDA, 2012), anorexia nervosa is a serious and potentially life-threatening disease in which eating disorders are characterized by hunger and excessive weight loss.
Etiology
The exact cause of anorexia nervosa is not known with certainty, but there are several factors as follows;
- Biological Factors
- Hunger or starvation will cause changes in neuropeptide activity and contribute to neuroendocrine disorders in anorexia nervosa patients.
- There is a research on the function of the hypothalamic-pituitary-adrenal (HPA) axis in patients with anorexia nervosa in principle found hypercortisolism in which HPA plays a role in releasing the hormone corticotropin which affects patients to anorexia. (Licino, 1996)
- The central pathway of serotonin eating regulates eating patterns and also participates in regulation of behavior and mood. Disorders of regulatory regulation and mood. Impaired regulation of serotonin regulation has implications for general depressive conditions that clearly will cause eating disorders. In the study of impaired serotonin regulation there is an increased risk of anorexia nervosa. (Jimerson, 1990)
- Determination of ghrelin, glucose-dependent insulinotropic polypeptide (GIP) provides an increased response to anorexia. A decrease in GIP occurs in objects, although a small intake of calories prevents rapid insulin response in patients with anorexia. (Stock, 2005)
- In conditions of depressed thyroid function, this abnormality can only be corrected by elimination. Hunger also causes amenorrhea that shows hormone levels (Luitenizing Hormone FSH, Gonadotropin, Realisine Hormone). Even so, some patients with anorexia nervosa suffer from amenorrhea before significant weight loss.
- Sociocultural factors, anorexia nervosa patients have a family history of depression, alcohol dependence or eating disorders.
- Psychological factors, fear of being fat, pressure to excel, social behavior that equates leanness with beauty.
Pathophysiology
In chronic conditions it provides a decrease in essential fatty acid
content (Holman, 1995) which provides manifestations of decreased
prostagladin synthesis as a constituent and protective mucous membrane
which causes the patient to have a high risk of mucous membrane injury.
Lack of fat intake and activities that are always carried out with the
aim of losing weight so that patients tend to be weak and provide
manifestations of disruption of daily activities, as well as the risk of
secondary infection from decreased immunity.
The condition of chronic anorexia nervosa also has an impact on
increasing the risk of osteoporosis as a result of shrinkage of bone
mass or bone mineral density decreases thus providing a risk of
pathological fracture. (Ringgoti, 1995)
Decreased calorie intake reduces fat reserves to be synthesized and
protein in the body, endocrine disruption involving the
hypothalamic-pituitary-gonadal axis occurs, resulting in estrogen
deficiency which causes amenorrea. Whereas in men fluctuating
testosterone levels that cause decreased erectile function and sperm
count. (Kimberly, 2011)
In addition, a lack of calorie intake will have an impact on decreasing
gastrointestinal motility, causing slowing of gastric emptying and
constipation. (Wals, 2008)
The most serious risk of anorexia is the deterioration of intolerable
physical conditions which increases the risk of death in some anorexia
nervosa individuals.
Clinical Manifestations
According to the National Eating Disorders Association (NEDA, 2012), anorexia nervosa has four main symptoms as follows;
- Resistance maintains weight at or above the minimum body weight that is normal for age and height.
- Fear of being fat, even though body weight is below normal.
- Dissatisfaction with certain aspects of physical appearance or serious self-rejection of low body weight.
- Loss of menstrual periods in girls and post-puberty women.
Anorexia nervosa patients can be treated well on an outpatient basis. However, if the patient shows any of the following signs, the patient must be hospitalized;
- Rapid weight loss is equivalent to 15% or more of normal body mass.
- Persistent bradycardia (50 times / minute or less)
- Systolic hypotension is less than or equal to 90 mmHg
- Hypothermia (core body temperature less than or equal to 36.1ºC)
- Medical complications found, suicidal thoughts
- Persistent sabotage or obstacles to outpatient therapy due to rejection of the condition and the need for therapy
Definition
Bulimia nervosa is a behavioral disorder characterized by fond of eating
followed by guilt, contempt and self-deprecation where vomiting is
induced alone, use of laxatives or diuretics, or restricting diet or
fasting to overcome the effects of overeating. (Kimberly, 2011)
Bulimia nervosa is a recurring episode of binge eating and then with
compensatory treatment (vomiting, fasting, serving, or a combination
thereof). Overeating is accompanied by the subjective feeling of losing
control when eating. Vomiting that is intentional or exaggerated, and
abuse of laxatives, diuretics, amphetamines and thyroxine can also
occur. (Chavez and Insel, 2007).
According to the National Eating Disorders Association (NEDA), bulimia
nervosa is an eating disorder characterized by excessive eating cycles
and compensatory behaviors such as self-induced (vomiting) are designed
to cancel or compensate for the effects of large meals outside normal
eating portions.
Etiology
The cause of bulimia nervosa can not be known with certainty, but there are factors as follows;
- Biological factors, mental disorders are also caused by chemical processes in the brain, namely the presence of neurotransmitter abnormalities in the brain, primarily the neurotransmitter serotonin is a trigger for bulimia nervosa.
- Psychological factors, appearance problems, lack of confidence in the weight they have, family conflicts.
- Cultural factors, excessive emphasis on physical appearance due to cultural influences.
Pathophysiology
Decreasing calorie intake will reduce fat and protein stores in the body. Estrogen deficiency occurs in women due to lack of pleated substrates for synthesis, causing amenorrea. Whereas in men, there is also a decrease in erectile function and sperm count as a result of fluctuating testosterone levels. (Kimberly, 2011)
Caused by repeated vomiting, a person suffering from bulimia nervosa will experience an electrolyte imbalance and nutrients are not fulfilled properly (malnutrition). Vomiting also causes erosion of tooth enamel, especially the surface of the tongue, the back of the tongue (because it is often affected by finger friction to induce vomiting).
Unlike anorexia nervosa, bumilia nervosa does not interfere with bone
mineral density, this can occur depending on age, body weight (the
thinner the more at risk). Most patients with bulimia nervosa experience
depression which results in suicide attempts.
Clinical Manifestations
According to the National Eating Disorders Association (NEDA, 2012) bulimia nervosa has three main symptoms as follows;
- Regular intake of large amounts of food is accompanied by a sense of loss of control when eating.
- Usually use inappropriate self-induced compensation behaviors such as vomiting, laxative or diuretic abuse, fasting, or exercise.
- Extreme attention to body weight and body shape.
Assessment
The identity examined includes name, age, gender, place of residence as a description of environmental and family conditions, and other information about the patient's identity.
- Psychological and lifestyle assessments are usually found in adolescents and consider themselves unattractive, unhealthy and undesirable.
- Psychosocococcal assessment and environmental conditions in the family.
The main complaint, the desire to be thin because they feel overweight.
- Previous medical history, often obtained by the use of appetite suppressant drugs, diuretics, laxatives (laxatives) or alchohol.
- Family health history, assesses whether or not a family has experienced bulimia or anorexia nervosa.
- Physical examination.Physical examination is carried out to assess any changes or disturbances to the vital function of anthropometry: Body weight and anthropometric examination is carried out to assess nutritional status. Widespread endocrine disruption involves the hypotalamus pituytary-gonadal axis, with manifestations in women as amenorrhoea and in men ie loss of interest and seyual potential.
