Li R, Li F. Unexplained Headache Due to Excessive Coffee Drinking: A Case Report. Case Study and Case Report 2024; 14(3): 27 - 29. ABSTRACT Caffeine, a central nervous system stimulant found in coffee, is widely consumed around the world. While moderate caffeine intake is generally considered safe, excessive consumption can lead to a variety of symptoms, including headaches. This case report presents a 45-year-old male with a history of frequent, unexplained headaches that were later attributed to excessive coffee consumption. The patient had been drinking more than six cups of coffee per day for several months, leading to significant caffeine-related symptoms, including headaches, insomnia, and irritability. Upon reducing caffeine intake, the patient experienced complete resolution of symptoms. This case highlights the need for healthcare providers to consider caffeine toxicity as a potential cause of unexplained headaches, especially in individuals with high coffee consumption.
