1: Anorexia Nervosa Cause:

The etiology of AN is complex and is a multifactorial disease involving many aspects such as social culture, psychology, and biology. In the past, AN was often considered to be a disease closely related to Western European and North American culture; but in recent years, with the development of globalization, the rapid development of the advertising industry, changes in eating habits, the emergence of a large number of fitness industries and the transformation of women’s social roles, There is growing evidence that many non-Western societies also have AN reports. In Western countries, there is a “slender” cultural pressure. A large amount of media information and marketing strategies create an atmosphere of dieting and success. Girls in their early socialization process think that slim women are more attractive than fat women. More successful. 

AN patients may have certain personality traits before illness, such as low self-esteem, perfectionism, stereotyped stubbornness, conservative inflexibility, sensitivity, rigorousness, introversion, timid retreat, hyperactivity, self-respect, self-centeredness, disharmony, childish, illusory, unable to insist on their own opinions, hesitating, etc., the requirements for success or achievement are very high. Clinical data confirmed that interpersonal relationships were tense, learning and life suffered setbacks, excessive stress, a maladaptive adaptation of the new environment, family disharmony, family members with accidents, serious illness or death, and their own accidents caused mental stress inhibition factors related to AN. Some children usually have poor eating habits such as partial eclipse, picky eaters, and good snacks. Parents pay too much attention to their children’s diet, repeatedly licking and forcing food. Instead, they reduce the excitability of the child’s feeding center and develop into AN. 

Genetic factors play a role in the pathogenesis of AN, which is confirmed by family studies and twin studies. However, the genetic pattern and genetic loci of AN have not been established. The neurobiology of AN has been further studied. The neurotransmitters involved are serotonin (5-HT), norepinephrine (NE), dopamine (DA), etc. There are also many neuroendocrine abnormalities in AN. Many hormones or neuropeptides are associated with appetite and satiety, and there are many complex interactions between different hormones or neuropeptides; for most neuroendocrine disorders, they are state-related, often after clinical recovery. It also returned to normal. In brain imaging, a number of CT studies have shown that patients with AN have enlarged CSF gaps during long-term starvation (brain sulcus and ventricle enlargement), and one study found that weight gain is restored; functional imaging studies found that patients had frontal and parietal lobe Cortical metabolism and perfusion are reduced, and local 5-HT dysfunction is presumed. 

2: Clinical Manifestations of Anorexia Nervosa

Patients refuse to seek medical treatment and treatment. They are often taken to the hospital by family members who find that they are thin, have little food, abdominal discomfort, long-term constipation, amenorrhea, and other problems.

1: Physical illness:

In patients with schizophrenia, delusions about food rarely involve calorie content, and patients often have a belief that food is poisoned; patients rarely have a preconceived notion of obesity, and there is no overactive activity common in AN patients.

2: Nutritional

The purpose is to restore normal body weight. Nutritional therapy, especially dietary intake, should start from a small amount, with a planned and step-by-step increase with the adaptation and recovery of physiological functions. In the initial stage, digestible and non-irritating foods are given, and depending on the condition, fluid, semi-liquid or soft food can also be used. Ensuring the intake of sufficient energy, protein, vitamins, and inorganic salts, the body’s function is restored, the body weight is gradually increased, and its normal body weight is restored. 

3: Drug treatment

Different requirements for drugs at different stages of AN disease, the acute treatment period mainly emphasizes rapid and effective weight gain, while the role of maintenance treatment is to prevent disease recurrence. Current medical treatments mainly rely on relieving compulsion (such as fluoxetine), improving depression (various antidepressants), alleviating certain physical symptoms such as delayed gastric emptying (cisapride and metoclopramide) and treatment The concept of overweight and near-imaginary beliefs (using antipsychotics) of their own body weight and body shape achieve the purpose of eating and gaining weight. In recent years, selective 5-HT reuptake inhibitors (SSRI), such as fluoxetine, have been found to prevent recurrence of AN.
