What can excessive consumption of caffeine lead to?

Excessive consumption of caffeine is known to lead to a range of physiological and psychological effects. When consumed in large amounts, caffeine can stimulate the nervous system significantly, resulting in symptoms such as excess sweating, anxiety, and gastrointestinal upset.

Anxiety often arises because caffeine increases adrenaline production, which can exacerbate symptoms of nervousness or panic. Additionally, it can lead to gastrointestinal discomfort as it stimulates gastric acid secretion, which may cause an upset stomach or worsen acid reflux. Excess sweating is another potential effect, due to heightened metabolic activity and increased heart rate that caffeine may induce.

In contrast, while increased appetite and weight gain can sometimes be observed in individuals with altered metabolism due to caffeine, it is not a direct consequence of caffeine itself but rather a secondary effect. Improved focus and mental clarity, as well as heightened energy levels without side effects, are often perceived benefits of moderate caffeine consumption, but they do not take into account the potential adverse effects that come with excessive intake. Understanding these impacts helps highlight the importance of moderation in caffeine consumption to avoid negative health consequences.
