This study aims to investigate how rapid eye movement (REM) sleep deprivation (SD) or recovery sleep affects rat weight and the serum levels of Nesfatin-1, Orexin-A, and Leptin; additionally, seeks to determine the impact of melatonin administration on these parameters. Male, Sprague Dawley rats were randomized into two groups (n=9). REMSD was induced using the modified multiple platform method (MMPM). Melatonin was used as a treatment (20 mg/kg). Study Group I was created to investigate the effectiveness of the treatment during REMSD. Study Group II was established to analyze the possible therapeutic role of melatonin and recovery sleep after REMSD-induced damage. The rats" weights were recorded during the experiments. Blood samples were collected from all rats via decapitation after experiments. The levels of serum Nesfatin-1, Orexin-A, and Leptin were analyzed using the ELISA method. REMSD affected weight of the rats and altered the levels of serum Nesfatin-1 and Leptin. Melatonin administration influenced weight gain and affected Nesfatin-1 and Leptin levels. REMSD or melatonin did not affect Orexin-A levels. REMSD and melatonin play significant roles in the body"s energy balance. This study will contribute to elucidating the role of SD in metabolic processes and will play a role in assessing the impact of melatonin, a commonly used treatment in human and veterinary medicine.
