Excessive coffee consumption may lead to the following negative effects:
1. Caffeine stimulates the central nervous system. Drinking too much coffee may cause adverse reactions such as palpitations, insomnia, and anxiety, affecting sleep quality and mental health.
2. Caffeine in coffee increases gastric acid secretion and irritates the gastric mucosa, intensifying gastrointestinal discomfort and potentially increasing the risk of gastritis and gastric ulcers.
3. Coffee's diuretic effect may lead to dehydration and affect electrolyte balance. Long-term excessive consumption may also increase the risk of osteoporosis.
4. For individuals who already suffer from peptic ulcers or gastritis, excessive coffee consumption may trigger severe gastrointestinal reactions, such as acid reflux, heartburn, stomach bloating, and stomach pain.
5. Caffeine can also increase heart rate. Excessive intake may lead to arrhythmia symptoms such as tachycardia and palpitations. Individuals with organic heart disease may experience severe arrhythmias.
Pregnant women and children should be particularly cautious about caffeine intake to avoid potential adverse effects on fetal development or children's growth.
