A medical condition caused by excessive caffeine consumption, characterized by symptoms like anxiety, tremors, insomnia, and heart palpitations; caffeine intoxication or overdose.
From caffeine plus the medical suffix -ism (indicating a disease, condition, or system). The term emerged in medical literature as caffeine use became widespread and doctors recognized its potential for harmful overconsumption.
Caffeinism is a real medical diagnosis—too much coffee or energy drinks can actually land you in the ER with symptoms that look like a panic attack. It's the literal opposite of what people wanted caffeine for in the first place!
