Answer

Answer

Many drinks contain caffeine. Caffeine is a natural diuretic, and it has a direct excitatory effect on bladder smooth muscle. Thus, caffeine-containing products produce excessive urine and exacerbate symptoms of urinary frequency and urgency. Caffeine-containing products include coffee, tea, hot chocolate, and sodas. Even chocolate milk and many over-the-counter medications contain caffeine.

Of caffeine-containing products, coffee contains the most caffeine. Drip coffee contains the most caffeine, followed by percolated coffee and then instant coffee. Even decaffeinated coffee contains a small amount of caffeine. Decaffeinated coffee contains an amount of caffeine similar to the amount in chocolate milk. Persons who consume a large amount of caffeine should slowly decrease the amount of caffeine consumed to avoid significant withdrawal responses such as headache and depression.
