<h4>Purpose of review</h4>The purpose of this review is two-fold: (1) to discuss a case report of idiopathic intracranial hypertension (IIH) after abrupt cessation of a glucagon-like peptide-1 (GLP-1) receptor agonist with resultant rapid weight gain and (2) to review the literature regarding the potential role of GLP-1 receptor agonists in the treatment of IIH as well as potential pitfalls.<h4>Recent findings</h4>GLP-1 receptor agonists have become widely used to treat obesity. Here, GCG is linked to obesity disorder.
