Treatment of co-occurring food avoidance and alcohol use disorder in an adult: Possible avoidant restrictive food intake disorder?

Objective: This case report details the presentation and treatment of a 42-year-old male self-presenting for treatment who reported having been a restrictive eater since childhood; since adolescence he had failed to meet appropriate nutritional intake with one meal at night followed by around 10–20 standard alcoholic drinks. Method: Ten sessions of cognitive behavioral therapy were offered emphasizing the need to adhere to regular eating patterns in conjunction with significant reduction of binge drinking. Results: At the end of treatment, and 1-month follow-up, improvements in nutritional intake and alcohol intake were observed, accompanied by improvements in depression, anxiety, and stress. Discussion: However, excessive alcohol intake had reoccurred at 3-month follow-up, accompanied by increases in negative affect and impairment due to eating, indicating that longer-term therapy may be required for this group of people.
