Final answer:
The primary treatment for ChaCha's binging and purging behavior, suggesting bulimia nervosa, includes mental health counseling, medications, and nutritional counseling, with hospitalization in severe cases. Recovery rates are promising though long-term management is often needed.
Step-by-step explanation:
Given ChaCha's pattern of binging and purging and the likely diagnosis of bulimia nervosa, the most appropriate primary treatment would involve a combination of mental health counseling, possible use of medications for co-existing mental health disorders, and nutritional counseling. These interventions aim to help patients gain control over their eating behaviors, establish normal eating patterns, and address the psychological aspects of the disorder. In severe cases, hospitalization may be necessary to stabilize the individual's physical health.
Approximately 50 to 85 percent of people with eating disorders recover with proper treatment. However, recovery is a long-term process, and some individuals may struggle with maintaining normal eating behaviors throughout their lives.
