Should You Drink Coffee on an Empty Stomach? The Surprising Answer

For many of us, the day doesn’t start without a steaming cup of coffee. But is it really a good idea to drink that first cup on an empty stomach? While the ritual is harmless for most, experts suggest there are a few potential pitfalls to consider—especially for those with sensitive stomachs or caffeine sensitivities.

Lauren Manaker, a health and nutrition expert, explained to Delish that for some people, coffee on an empty stomach might lead to digestive discomfort. The acidic nature of coffee can trigger heartburn or acid reflux, particularly if you’re prone to stomach issues. Amy Brownstein, a registered dietitian, recommends pairing coffee with food or adding milk or a non-dairy alternative to help buffer the stomach lining and reduce acidity.

But it’s not just about digestion. According to additional research from Health.com, drinking coffee without food can spike cortisol levels—the stress hormone that naturally peaks in the morning. This might amplify feelings of anxiety or jitters, especially for those already sensitive to caffeine. On an empty stomach, caffeine is absorbed more quickly, intensifying its effects.

Moreover, a study from Arrowhead Coffee highlights how coffee can temporarily raise blood sugar levels, leading to energy crashes and irritability later in the day. This is particularly concerning for people with insulin sensitivity or diabetes. Brownstein notes that adding milk or a snack to your coffee routine can help stabilize blood sugar and maintain energy throughout the morning.

If you’re noticing mid-morning fatigue, jitters, or digestive discomfort, it might be worth rethinking your coffee habits. Experts suggest starting the day with a glass of water, followed by coffee paired with a small meal or snack. “Listening to your body is key,” Manaker advises. “If you experience discomfort, adjusting your routine could make a big difference.”

The bottom line: coffee on an empty stomach isn’t inherently bad, but it might not be the best choice for everyone. Pay attention to how your body responds and adjust as needed.
