Idiopathic Intracranial Hypertension is primarily observed in obese female and weight management promotes disease control by yet unsettled mechanisms. Effective, fast and lasting weight loss is crucial, however, hard to achieve. Current weight management strategy in IIH in Denmark is counselling by a dietician. This study investigates whether an initial Very Low Calorie Diet (max 800 kcal/day) for 8 weeks following the diagnosis combined with GLP1-RA treatment throughout 10 months is tolerated and more efficient in achieving substantial weight loss and reduction of intracranial pressure. Furthermore, a number of secondary outcomes are measured including headache burden, quality of life, structure and function of the optic nerve, non-invasive surrogate markers of intracranial pressure, body fat mass, bone health, fatty liver disease and a range of cerebrospinal-, blood- and urine markers of i.a. the hormonal, inflammatory, metabolic, and headache biomarker profile.
The intervention may candidate as a future first-line treatment regime.
