Paradoxical consequence of human chorionic gonadotropin misuse

Recombinant human chorionic gonadotropin (hCG) is commonly misused as a weight reducing or performance enhancing agent but is associated with increased risk of thromboembolic events. A 29-year-old female with a history of obesity was admitted to our center with a diagnosis of ischemic stroke. Etiologic workup revealed a large patent foramen ovale and history of recent use of hCG as part of a weight loss regimen. This report highlights the potential complications of hCG therapy, particularly when used for unapproved indications and without medical supervision.
