Abstract
BackgroundObesity and eating disorders can present together, and pose diagnostic and therapeutic challenges to the clinician. Generally, lifestyle interventions alone for the treatment of obesity have modest long-term effectiveness. Phentermine–topiramate extended release is a relatively new medication approved for weight reduction. Sleep-related eating disorder is a rare condition that is often underdiagnosed. Both conditions are chronic and require long-term management. There is no definitive treatment for sleep-related eating disorder, and therapeutic options are based on case reports.Case presentationA 35-year-old Caucasian male with a body mass index of 41.7 kg/m2 presented for obesity treatment. History revealed nocturnal episodes of hyperphagia associated with amnesia of overeating and other features of sleep-related eating disorder. Treatment was initiated with phentermine–topiramate extended release. Five months later he lost 5% of his body weight and demonstrated resolution of sleep-related eating disorder behaviors. He reported no adverse side effects. Upon self-discontinuation of the medication, his eating disorder recurred.ConclusionsClinicians intending to help patients reduce body weight should screen for nocturnal eating and other eating disorders. Sleep-related eating disorder can be associated with significant morbidity and excess weight. Patients report adverse effects on quality of life as a result. Phentermine–topiramate extended release may be a good therapeutic option for patients presenting with comorbid obesity and sleep-related eating disorder. More research is needed to explore the efficacy and safety in this patient population.
Highlights
Obesity is a complex disease with multiple contributing factors and great etiological heterogeneity among individuals
We present a case of a patient with obesity and Sleep-related eating disorder (SRED) treated with phentermine–topiramate extended release (PHEN-TPM Phentermine–topiramate extended release (ER)), resulting in the dual benefit of weight loss and resolution of pathologic hyperphagia at night
Here we present a case of a patient with obesity and SRED that responded promptly to standard dose PHENTPM ER
Summary
Obesity is one of the most common chronic diseases encountered in clinical practice. SRED is uncommon and is rarely diagnosed or considered when assessing patients with excess weight. Presence of eating disorders should be screened for when evaluating a patient for weight reduction strategies. When diagnosed as comorbid conditions, healthcare professionals should consider the use of PHEN-TPM ER as dual therapy
