The treatment of anorexia nervosa requires an integrated approach involving medical, nutritional, and psychological support, aiming to restore normal body weight, improve psychological symptoms, and prevent long-term complications. Treatment plans are typically tailored to the severity of the condition, ranging from outpatient follow-up to inpatient care. The treatment team usually includes psychiatrists, dietitians, and psychotherapists, working collaboratively to coordinate various interventions.
The treatment process emphasizes the concept of "holistic medicine," focusing not only on restoring physiological indicators but also on addressing patients' distorted perceptions of weight and appearance. In the early stages, nutritional rehabilitation may be prioritized, followed by gradual psychological intervention. The effectiveness of treatment often takes months or even years, with active participation from patients and their families being crucial.
Current strategies focus on three core components: nutritional recovery, psychotherapy, and medical monitoring. Patients with acute malnutrition may require hospitalization to ensure safe caloric intake. Outpatient treatment involves regular follow-up to adjust dietary plans and incorporate psychotherapy to modify pathological thinking patterns.
Hospitalization is suitable for patients with unstable vital signs (such as arrhythmias, severe underweight) or high suicide risk. The medical team will set daily caloric goals and may use nasogastric or feeding tubes in extreme cases. Outpatient treatment involves weekly monitoring of weight and dietary diaries to help patients gradually establish normal eating habits.
During the nutritional recovery phase, the team will set daily caloric increase targets of 500-1000 kcal based on the patient’s weight, age, and physiological needs. This process should avoid excessive rapid escalation to reduce the risk of metabolic crises. Dietitians will design diverse meal plans and teach patients to read nutrition labels and adopt healthy cooking methods.
Medications in the treatment of anorexia nervosa are mainly used to manage comorbid conditions rather than directly treating core symptoms. Antidepressants such as SSRIs may be used to improve associated depression or anxiety, but only after weight restoration to prevent abnormal drug metabolism.
Selective serotonin reuptake inhibitors (SSRIs) are common choices but require combination with psychotherapy for optimal effect. Studies show that using SSRIs in patients who have regained normal weight can reduce relapse rates. However, these medications may be ineffective during acute malnutrition, as neurotransmitter metabolism abnormalities require physiological stabilization before improvement occurs.
Psychotherapy remains the main treatment modality, with cognitive-behavioral therapy (CBT) and family therapy being the most evidence-supported methods. Therapists help patients identify distorted body image perceptions and challenge pathological thoughts through behavioral experiments. Family therapy, especially for adolescents, aims to strengthen family support systems.
Enhanced CBT (CBT-E) is specifically designed for anorexia nervosa, addressing issues related to body image, restrictive eating behaviors, and emotional regulation through five therapy modules. Therapists assist patients in establishing the concept of "normal eating ranges" and use behavioral experiments to expose them to short-term hunger scenarios to reduce fears of "binge eating."
For patients under 18, family therapy focuses on creating a supportive family environment. Initially, family members assist in monitoring eating, gradually transferring autonomy back to the patient. Studies show this approach can reduce relapse rates in adolescent patients by over 30%. Family members need to learn to recognize signs of pathological behaviors and avoid applying pressure during treatment.
The success of treatment depends on ongoing lifestyle adjustments. Patients should establish regular meal schedules and avoid excessive exercise or behaviors that trigger binge episodes. Dietitians design "neutral" meal plans to reduce anxiety related to specific foods.
Excessive exercise is a common compensatory behavior. Therapists set daily exercise limits (e.g., no more than 60 minutes of moderate-intensity activity per day). Wearable devices are used to track activity levels, and patients are educated to distinguish "healthy exercise" from "compensatory behaviors."
Emerging research explores neuroplasticity and cognitive repair techniques. Functional MRI (fMRI) shows abnormal activity in the prefrontal cortex, which may serve as a treatment target. Non-invasive brain stimulation methods like transcranial magnetic stimulation (TMS) are in clinical trials, showing potential cognitive benefits for some patients.
Personalized medicine trends include developing genetic testing to identify biomarkers associated with better responses to specific treatments. AI-assisted behavioral therapy programs can analyze dietary diaries in real-time to provide customized feedback, potentially becoming an essential supplement to future treatments.
Research indicates that certain nutrients like Omega-3 fatty acids may improve brain development and emotional regulation. Clinical trials are testing combined therapies involving high-protein diets and cognitive training to restore both physiological and psychological functions. Gut microbiota modulation is also a new research direction, with probiotic supplementation and specific dietary patterns potentially improving metabolic abnormalities.
Seek professional help immediately if signs such as weight below 85% of standard, refusal to eat normally for over six weeks, self-harm behaviors, or persistent body image disturbances occur. If physiological complications like arrhythmias, bone density loss, or electrolyte imbalances develop, hospitalization is necessary.
For adolescents, if weight does not reach 85% of normal within three months of treatment or if purging behaviors persist after binge episodes, reevaluation of the treatment plan is required. The team will adjust treatment intensity based on scores from the Hamilton Depression Rating Scale (HAM-D) and weight trend charts.
If the patient exhibits behaviors such as calculating calories for more than three hours daily, hiding food, or using metabolic stimulants (e.g., excessive caffeine), immediate intervention is needed. These behaviors can lead to organ failure or rapid deterioration of mental health. Family members should communicate regularly with the treatment team to monitor progress.
Family-centered treatment (such as the Maudsley approach) is suitable for early-stage and younger patients, especially when family relationships are not severely conflicted. Therapists assess family members’ willingness to participate and communication patterns. If the patient resists treatment or family support is lacking, adjustments may be necessary.
What is the role of a dietitian during recovery from anorexia nervosa?The dietitian develops personalized meal plans to help patients gradually restore normal eating habits and monitors weight and nutritional indicators. They also educate patients to recognize incorrect dietary beliefs and collaborate with psychotherapists to ensure that psychological needs are addressed alongside nutritional goals.
How is the "weight recovery target" set?Weight targets are usually based on the patient’s specific BMI and medical history, aiming for at least 95% of the "minimum healthy weight" to prevent complications. The goals are determined by the medical team based on cardiac function, bone density, and other physiological indicators, not solely on "normal ranges."
What non-pharmacological methods can help reduce anxiety or resistance during treatment?Cognitive-behavioral therapy (CBT-E) helps challenge unhealthy thought patterns, mindfulness training can alleviate compulsive anxiety, and art therapy or group support provides non-verbal outlets. The medical team also adjusts the pace of treatment to prevent overwhelming the patient.
What misconceptions about this disease should be corrected?Common misconceptions include "recovery is solely a matter of willpower" or "only controlling food intake is necessary." Effective treatment requires an integrated approach involving psychological, nutritional, and medical care. Public education should also address the risks faced by male and Asian patients to reduce stigma and increase awareness.
