caffeine toxicity

Caffeine toxicity occurs when someone consumes too much caffeine, leading to harmful effects on the body. Excess caffeine can cause symptoms like rapid heartbeat, increased blood pressure, dizziness, insomnia, stomach upset, and nervousness. In severe cases, it may cause arrhythmias or seizures. The amount needed to reach toxicity varies depending on individual sensitivity, but generally, consuming over 400 milligrams (about four cups of coffee) regularly can increase risks. It’s important to monitor intake and recognize symptoms early to prevent serious health issues. If overdose symptoms appear, seek medical attention promptly.
