What organs get affected by caffeine?

Caffeine primarily affects the brain, where it acts as a stimulant, increasing alertness and reducing fatigue. It also impacts the heart by increasing heart rate and blood pressure temporarily. Additionally, caffeine can influence the digestive system, promoting increased gastric acid production, which may lead to digestive discomfort in some individuals. Other organs, like the kidneys, may experience increased blood flow and diuretic effects due to caffeine consumption.
