But do you know what happens when you consume caffeine on an empty stomach?

In this short guide, we’re going to look at four of the most common responses that occur when you drink coffee.

Enhanced Alertness

When you consume caffeine on an empty stomach, your body will absorb it more quickly. Although you’re probably used to feeling sharp and alert after drinking caffeine, you can experience these feelings more rapidly if you haven’t first had your morning breakfast.


Caffeine can cause your digestive tract to contract, and it can also increase the production of stomach acid. This can make you feel queasy if there isn’t any food in your stomach.

After caffeine intake, the acid could also rise up into your esophagus, leading to heartburn. This can be painful and could even cause severe damage if it frequently occurs over an extended period.

Your physician may be able to provide heartburn medication, but you can also try eating a meal before you have a cup of coffee.

Feelings of Unease

Caffeine stimulates your central nervous system, and it can make you feel uneasy if it’s consumed in large amounts. If you haven’t had food, your body’s swift absorption of caffeine can lead to this feeling occurring quickly, leaving you unsettled.

While this won’t happen to everyone, it can be unpleasant if it occurs. The good news is that there are several great ways you can reduce your coffee jitters. You can then enjoy a cup of coffee while feeling calm and composed.

Desire to Urinate

When you drink too much caffeine on an empty stomach, you could need to urinate more often. This can happen because coffee is a diuretic that encourages your body to flush out water. But, it can also be because there is a high water content in coffee, meaning your body will need to urinate anyway.

If you’re going to drink coffee before you eat breakfast, make sure you go to the bathroom before commuting to work.

Drinking Caffeine on an Empty Stomach Isn’t Always a Good Idea

While you can drink caffeine on an empty stomach, it could be better to eat breakfast first. Although you may be more alert, you might also feel jittery and experience heartburn. It’s also possible you’ll have to go to the bathroom more often.

By including caffeine as part of a balanced diet, you can enjoy the benefits without these potential side effects.
