5. Irritability
The extreme consumption of coffee can lead to irritability, neurologists say. And this is linked to the issue we discussed earlier, which is anxiety disorder. A lot of people who suffer from this condition become agitated if they consume less caffeine than the average individual.
However, if you notice a change in your behavior (you may feel angrier or more tensed than usual) and know it’s because you increased your daily caffeine intake, it’s time to cut back or replace it with tea.
6. Gastrointestinal issues
For a good majority of people, the first thing they do in the morning is drink a cup of coffee on an empty stomach because this helps them get their bowels moving. Caffeine’s laxative effects increase activity and aid in colon cleansing. And the good news is that even the decaf has the same effects!
While drinking a moderate amount of coffee per day can help your body regulate, drinking too much coffee can cause diarrhea and stomach ulcers. In addition to these side effects, a small percentage of people experience gastroesophageal reflux disease, also known as GERD, which is mostly caused by too much caffeine or acidic foods like lemons, oranges, and grapefruits.
