8 Side Effects of Caffeine Overdose on Overall Health


Consuming too much caffeine can interfere with your sleep cycle, making it hard to fall asleep and stay asleep.

Increased Heart Rate

High doses of caffeine can cause your heart rate to spike, leading to palpitations and a racing heartbeat.

Anxiety and Jitters

Excessive caffeine can lead to increased anxiety levels, nervousness, and jitteriness.

Digestive Issues

 Overconsumption of caffeine can cause stomach upset, acid reflux, and even diarrhea.

High Blood Pressure

 Caffeine can cause a temporary spike in blood pressure, which can be dangerous for those with hypertension.

Dependency and Withdrawal

Regular high intake of caffeine can lead to dependence, and sudden cessation can result in withdrawal symptoms like headaches and irritability.


Paradoxically, consuming too much caffeine can lead to increased fatigue once its effects wear off.

Bone Health

Excessive caffeine can interfere with calcium absorption, potentially leading to weaker bones and an increased risk of fractures.
