Is it bad to drink coffee on an empty stomach?

Concerns & risks

You were trying to wake up with a coffee before breakfast, but sometimes your stomach feels sour after.

Some people get heartburn or jitters.

Causes & evidence

Effects vary person to person.

What to do

1. Notice symptoms like heartburn or jitters.
2. Try eating something small first.
3. Hydrate with water too.
4. Limit caffeine late in the day for sleep.

Common mistakes: Common mistakes: ignoring repeated heartburn or stomach pain. Some people feel fine; others notice discomfort. Try having something to eat with it. Watch how much caffeine you have overall. Persistent stomach issues are worth discussing with a provider. Pay attention to what you add, too. Lots of sugar or large sizes can make you jittery or crash later. If coffee makes you shaky, anxious or keeps you up at night, try a smaller cup or switch to half-caf. Drinking water alongside coffee is a simple habit that keeps you hydrated. Listen to your own body; everyone reacts a little differently, and there's no single right answer.

Speed Man tip: Coffee late in the day can hurt sleep. See sleep basics.

Wrap-up: Effects vary. Try food first. Watch caffeine timing.
