Clinical loss of appetite is associated with anxiety disorders, to thoroughly improve the clinical symptoms of patients, active anxiolytic treatment is necessary, and 5-hydroxytryptamine 1A receptor partial agonists such as buspirone and tandospirone can be selected to control the patient’s symptoms, and antidepressants with anxiolytic effects such as sertraline, paroxetine, citalopram, escitalopram, venlafaxine, and duloxetine can also be selected to improve the patient’s clinical symptoms. Regardless of which drug is chosen, it takes about 1-3 weeks to start taking effect, and side effects such as dizziness, headache, diarrhea, constipation, and poor appetite may also occur in the early stage of drug use. However, the side effects are not usually long-lasting and will slowly disappear in about 10 days. In addition to the above-mentioned medication, psychological treatment for patients with anxiety disorders also has a very important role to play. Health education can be used to let patients clarify the nature of the disease, know that the loss of appetite is emotionally related, refrain from blind worry, fear and dread, believe that there are no actual lesions in the body organs, and interrupt the vicious cycle that has been formed. Cognitive-behavioral therapy can also be used to improve patients’ misperceptions, so that they can correctly understand the possibility of negative events and avoid overly dramatic or catastrophic imaginations about the outcome of things. Of course, behavioral treatments such as relaxation training, breathing training, and distraction techniques are also helpful for the control of patients’ clinical symptoms.
