Yes, even a coffee junkie must have limits. The Food and Drug Administration recommends that a healthy person have a maximum of 3 to 5 cups of coffee daily. So, excess coffee can affect your digestive system, and you may feel nauseous and shaky when you down cup number eleven.

High caffeine sensitivity

Some people are susceptible to caffeine. This means that their bodies metabolize coffee slowly. This sometimes makes you feel sick when you consume coffee. So, if you get sick while consuming coffee, it may be in your genes.

Drinking coffee on an empty stomach

Sometimes you drink coffee on an empty stomach, which is not recommended. Coffee is acidic, and it irritates your stomach lining if you are a sensitive person. Therefore, the caffeine and acidity in your coffee will result in coffee-induced nausea.

Excessive creamers and sweeteners in your coffee

Additionally, you could be adding excessive creamers and sweeteners to your coffee. Sweeteners, for example, cause a fast rise in your blood sugar followed by an immediate sugar crash. Therefore, your body feels fatigued, and you can get nauseous.

If you realize that you suddenly have an aversion to coffee, you could also be lactose intolerant. Maybe you’ve been taking your coffee with milk, but suddenly, you can no longer do so. You could have developed lactose intolerance which typically develops as you grow older.


Caffeine is a diuretic, which means that it removes water in your body, risking you from getting dehydrated. For this reason, coffee lovers are always advised to drink water often, even as they enjoy their coffee. It is interesting how coffee drinkers will not miss grabbing a cup daily, yet forget the importance of drinking water. So, if you start feeling nauseous, ask yourself when was the last time you had a glass of water.

Surprise! You could be expectant. At least this was the case for my friend last year. The body works in mysterious ways, and at times, it can non-consciously avert your drinking to prevent your body from ingesting something harmful to the baby. Remember that health experts do not recommend coffee intake during pregnancy, stating it is harmful.

Reaction with medication

You may be on medication, and your nausea could result from the coffee’s reaction to your drugs. It is not recommended to combine caffeine which stimulates your body, with other steroids and stimulants.

What should you do if you feel nauseous after drinking coffee?

There are various practices you can try to combat nausea when consuming coffee.

  • Drink as much water as possible because it is necessary for our bodies. This will ensure you stay hydrated even as you enjoy your beverage.
