Randomized trial identifies distinct metabolomic profiles in idiopathic intracranial hypertension, suggesting novel insights into obesity-related mechanisms.
Obesity is a well-established risk factor for idiopathic intracranial hypertension (IIH), yet the metabolic mechanisms linking obesity to IIH remain poorly understood. Previous metabolomic studies in obesity have identified characteristic alterations in lipid and amino acid pathways, but it is unclear whether individuals with IIH exhibit distinct metabolic profiles beyond those attributable to obesity alone. The objective of this study was to identify metabolomic differences between patients with newly diagnosed IIH and age-, sex-, race/ethnicity-, and body mass index (BMI)-matched controls.
