Mostly, caffeine tends to affect the central nervous system of the brain by producing a molecular structure that mimics the work of adenosine and bind to adenosine receptors in the brain cells to cause stimulation (Pohler, 2010).

These caffeine molecules tend to replace adenosine and thus interrupts them to cause increased neuron firing in the brain that makes coffee drinkers feel more relaxed and awake. Also, caffeine affects digestive and excretory systems and may cause heartburn or stomach upset, and since much of this substance is not stored in the body, liver processing caffeine can result to increased urination and lead to stomach problems such as ulcers or acid reflux (Pohler, 2010).

Caffeine if taken in large amounts by pregnant women travels in the bloodstream to the placenta and causes an increase in metabolism and causing slowed fetal growth (Nawrot et al.
