Drinking a lot of coffee can cause pain in the stomach. The acidity may also increase the chance of heartburn.
In rare cases, caffeine can cause a serious reaction called rebound headache. This is a severe headache that returns after you’ve stopped taking caffeine.
Caffeine may also cause a headache in some people after they’ve already been drinking it.
It’s important to follow the caffeine guidelines below.
Which type of coffee is best?
In general, caffeinated coffee has more caffeine and less of the other ingredients, like sugar, than decaffeinated coffee.
Decaffeinated coffee has fewer calories than regular coffee, but they’re still considered high-calorie drinks.
There’s also some evidence that drinking decaf coffee may help you lose weight. It may be that caffeine blocks your body’s fat-burning ability.
Decaffeinated coffee won’t help you lose weight or keep your weight down if you have a disease like diabetes.
Caffeine is also a diuretic, meaning it can cause you to urinate more. This can lead to dehydration.
If you have a condition that means you may be more likely to have dehydration, such as kidney or liver disease, ask your doctor before increasing your caffeine intake.
