Takeaway
The incidence and prevalence of idiopathic intracranial hypertension (IIH) is increasing and is associated with obesity. This has important implications for healthcare professionals and policy makers given IIH-associated comorbidities, complications and healthcare utilisations.
Why this matters
IIH is strongly associated with obesity, and obesity is an increasing global burden. It would seem plausible to assume the incidence of IIH and its associated healthcare utilisation is increasing.
Large population studies regarding epidemiology, healthcare use and outcomes of people with IIH in Wales are limited.
