Diuretics are substances that make you pee more, they make your body lose water. Beverages containing alcohol and caffeine are sort of accidental diuretics - that is, they're not drunk with the purpose of losing water but it happens anyway. Then there are substance that are taken with the explicit purpose of losing water.
Caffeine is a mild diuretic and will lead to a mild increase in urine output for a short time. Caffeine will also raise blood pressure slightly for a short time. These changes are short lived and are not permanent.
