Introduction: Traumatic brain injury is a significant global health concern. It often results from high-velocity accidents and leads to diffuse axonal injury, causing consciousness disorders and potentially permanent cognitive and behavioural changes. Individuals with traumatic brain injury often exhibit weight gain, potentially leading to obesity. This weight increase is influenced by cognitive dysfunction, reduced physical activity and metabolic changes.
Case report: A 23-year-old woman suffered a traumatic brain injury after a traffic accident, with an initial Glasgow Coma Scale score of 5/15. Positive neurological improvement was observed during her stay in the intensive care unit and the neurosurgical department. Subsequently, she was transferred to the rehabilitation department, where she faced significant challenges, including mood fluctuations, cognitive impairments and substantial weight gain. Her body mass index (BMI) increased from 23 kg/m2 pre-accident to a maximum of 36 kg/m2, despite interventions like medications and lifestyle changes. Blood tests revealed insulin-resistance and metformin initiated a successful weight reduction.
Conclusion: Managing weight gain following traumatic brain injury requires effective interventions that acknowledge its complexity and multifaceted nature, including lifestyle modifications, behavioural therapy and potentially pharmacotherapy or bariatric surgery. Further research is essential to better understand underlying mechanisms and evaluate intervention effectiveness in this specific patient population.
