How long does it take for coffee to leave the body?

There's no single answer to how long coffee stays in your body. It depends on several factors:

* Individual Metabolism: How quickly your body processes caffeine varies.

* Amount Consumed: More coffee = more caffeine, which takes longer to break down.

* Other Factors: Age, weight, health conditions, and even medications can affect how caffeine is metabolized.

General estimates:

* Half-life: Caffeine's half-life is about 5 hours, meaning your body eliminates half the caffeine every 5 hours.

* Complete Elimination: It typically takes 6-12 hours for your body to eliminate 90% of caffeine.

* Trace Amounts: Caffeine traces may still be detectable in your urine for up to 24 hours after consumption.

Important Note: Even though traces may remain, you'll likely feel the effects of caffeine within a few hours, with most of the effects wearing off within 8-10 hours for most people.

If you're concerned about caffeine's impact on your body, talk to your doctor.
