Energy drinks are a great choice for busy people who want that boost. However, too much of it could lead to unintended effects, just like anything else.

This blog will help you answer “Why do energy drinks give me diarrhea?” and highlight some of the dangers of drinking too much.

Why Do Energy Drinks Give Me Diarrhea?

The primary ingredients in energy drinks are caffeine and sugar. Both of these ingredients can give you the runs if taken at high levels.

While caffeine will give you the energy you need to get through the day, it is also responsible for stimulating bowel movements as well as softening stools.

For more detail, caffeine in energy drinks has stimulating effects that may lead to gastrointestinal complications such as diarrhea or loose stools. Dehydration is another risk when drinking too much.

Moreover, artificial sweeteners really don’t agree with certain people’s tummies. For those with a hypersensitive stomach, these additives can send them running to the bathroom, which is not a pleasant experience for anyone involved.

It may be unpleasant to some at first, but it’s a normal reaction when your body consumes too many caffeinated beverages. Once you stop drinking, this annoying symptom will end.

What Are Other Effects On My Stomach When Consuming Too Much Energy Drinks?

Stomach Upset

These beverages may contain simple carbohydrates with a higher content than others and thus can upset your stomach.

The effect of a caffeinated beverage could give you a boost of power to your muscles – but not because they are energized; it’s just that they were given a lot of stimulants.

Serious Gastritis

Caffeinated beverages are not all created when it comes to the risk of developing gastritis.

Many people drink them and aren’t at risk of the condition. Still, if you develop gastritis, you’ll suffer from some common symptoms such as stomach inflammation and burning, ulcerations, or bleeding in the stomach area or small intestine. The likely culprit is energy drinks’ high doses of caffeine – studies show that excess caffeine increases the production of stomach acid.

Caffeine’s Side Effects

Unfortunately, diarrhea is not the only symptom you can suffer from when drinking too many caffeinated beverages. In most cases, negative side effects associated with caffeine consumption are usually mild and may include irritability, difficulty sleeping, tremors, etc.

However, consuming large amounts of caffeinated beverages could stress your heart. It’s really tricky to know exactly how much is too much because individual health can play a factor, as well as one’s daily caffeine tolerance level.

Other Symptoms

Caffeine is an ingredient that plays a major role in these beverages, but there is also sugar and all sorts of other stuff in them, which are not listed on product labels.

For example, carnitine and guarana may be harmless in small doses on their own but no longer healthy when mixed with the high levels of caffeine found in those beverages.

They can disrupt the way one’s stomach digests food, along with also causing some physical complications, such as stomach cramps and vomiting or nausea.
