3. Frequent headaches and dizziness
Caffeine sometimes relieves migraines, but excessive use or sudden cessation can provoke headaches and dizziness. Long-term high intake narrows the blood vessels in the brain, which causes tension headaches. Conversely, a sharp decrease in dependence leads to withdrawal symptoms: throbbing pains, dizziness, irritability. Gradual adjustment prevents these problems.
4. Fast, irregular, or pounding heartbeat
Caffeine stimulates the heart and can increase heart rate and blood pressure. In sensitive people or those with cardiovascular disease, excessive coffee can cause palpitations, arrhythmia, or chest discomfort. If you experience these symptoms after coffee, it is a serious sign to cut back on caffeine and consult a doctor if the symptoms persist.
5. Dyspepsia and acid reflux
Coffee is acidic and can irritate the stomach lining, causing heartburn, reflux, and pain. Drinking coffee on an empty stomach increases stomach acid production. If you often experience stomach discomfort after drinking coffee, reducing the amount you drink or drinking it with food may help. Persistent gastrointestinal symptoms require medical evaluation.
6. Addiction and strong desire
If you need coffee to function normally – you can’t start your day or have a hard time concentrating without it – this is a sign of addiction. Your body has adapted and requires caffeine to function normally, which reduces your natural energy and leads to tolerance: you need more and more caffeine to get the same effect. Recognizing addiction is a key step towards restoring natural balance.
7. Fatigue despite coffee intake
Paradoxically, too much coffee can lead to chronic fatigue. Caffeine temporarily increases adrenaline, but excessive use depletes the adrenal glands and the body’s reserves. The result is a feeling of constant fatigue and brain fog, regardless of the amount of coffee. This signals that the body needs rest and less caffeine.
