What are the side effects of drinking too much espresso?

In this text we are going to provide the answer to the question: “What are the side effects of drinking too much espresso?”. In addition, we are going to talk about the effects of drinking a lot of espresso and consequently ingesting too much caffeine.

What are the side effects of drinking too much espresso?

Drinking too much espresso can cause symptoms such as upset stomach, tremors and even insomnia. The maximum recommended dose of caffeine per day is 400 mg, equivalent to 3 espressos per day.

In addition, we need to be careful with the ingestion of other products that contain caffeine, since this substance is also present in energy drinks, in some training supplements, black tea, medicines, green, maté and black teas and even in cola-type soft drinks.

Like some drugs, caffeine can also cause an overdose. Cases of death from excess caffeine in the body have been reported.

Some studies indicate that the maximum concentration of caffeine in the body is 50 mg per ml of blood, and it can kill a person.

What happens if you consume too much caffeine?

Too much espresso can cause some problems such as cardiovascular problems, headache, nausea, dizziness, chest pain, cardiac arrhythmia, tiredness and sleep.

Regular consumption of two to three cups of coffee a day contributes to cardiovascular health. In addition, it amplifies alertness, which can be useful in studies, improves mood. However, too much coffee can also interfere with your sleep.

The effects of coffee depend on how each body metabolizes caffeine. Individuals considered to be fast metabolizers can eliminate caffeine more quickly and still receive the benefits from coffee, such as the antioxidant effect.

People who have ulcers, gastritis and hypertension should reduce and limit the amount of coffee ingested. In addition, hypertensive people and pregnant women are part of the group that need to be extra careful when consuming coffee, since the tolerable limits are very low.

Other problems can be caused by too much coffee, such as:

  • Nervousness
  • Anxiety
  • Tiredness
  • Nausea and diarrhea
  • Headaches
  • Increased blood pressure
  • Tremors in the hands
  • Increased heart rate
  • Elevation of cholesterol levels.

If an espresso is no longer enough to keep you “awake”, chances are you have developed a tolerance to caffeine. This occurs when the drink seems to “stop working” for those looking to avoid sleep and stay awake.

If you are increasing the amount of coffee ingested a lot, the suggestion is to decrease this amount gradually to let the body get used to the levels of caffeine ingested. 

Be careful when trying to eliminate caffeine at once, for those who already feel dependent, it is important to know that reducing or eliminating caffeine consumption can result in withdrawal symptoms such as fatigue, mood swings, headache, tremor, lack of focus and nervousness.

Did you know that caffeine is not just in coffee?

If you don’t like coffee and still would like to have the beneficial effects of caffeine, you can consume other products that also have caffeine in their composition.


A cup of tea can contain 20 to 90 milligrams of caffeine.

  • Green tea: One cup of green tea contains 25 to 40 mg.
  • Black tea: One cup of black tea contains 15 to 60 mg.

Caffeine in capsules and medications

There are many medications that use caffeine in its components to take advantage of its effects on the body.

Also, if you prefer pure caffeine, you can buy caffeine in capsule form and consume it 1-2 times a day. This lets you know exactly how much caffeine you’re getting.

In addition, too much caffeine can bring various health problems, such as dizziness, stomach problems and diarrhea. The ideal is to consume foods that have caffeine moderately.
