Like tea and other beverages, coffee is a natural diuretic. But the extent of the impact also depends on personal tolerance, weight and age. In addition, caffeine content and coffee consumption also affect the diuretic effect.

Second, coffee contains caffeine, which will be completely absorbed by the stomach and small intestine after ingestion. Caffeine is then broken down in the liver to produce three primary metabolites: paraxanthine (84%), theobromine (12%), and theobromine (4%). Among them, theobromine belongs to the category of "phosphodiesterase inhibitors". Phosphodiesterase inhibitors have the effect of dilating blood vessels and increasing urine volume by increasing the cAMP content in vascular smooth muscle cells.
