Why Does Iced Coffee Make You Poop?

Does Iced Coffee Make You Poop? Most people know that drinking iced coffee after a meal can cause gastrointestinal distress that may lead to diarrhea, stomach cramps, and vomiting. The majority of people don’t understand why their digestion changes when they drink cold brew.

There are many reasons you might end up with a stomach problem after drinking iced coffee – improper dosing, over-use of ice, and an incorrect mixture of sweeteners and milk. However, one common reason that most people have a tough time understanding is that the drink is too cold. In this article, we break down the causes of such nighttime digestive woes, so you can start getting better sleep at night.

Does Iced Coffee Harm Your Digestive System?

Before we discuss any solutions or tips, let’s take a moment to look at what happens in the body when you drink iced coffee. Cold beverages contain less water than normal drinks. This means they will have a lower concentration of dissolved compounds – like caffeine – and other volatile compounds. When you consume cold drinks, your body reacts by increasing gastric acid secretion and intragastric pressure (pressure inside your stomach). 

The increased pressure causes discomfort and stomach pain, especially if the beverage is very acidic or has been diluted with ice. Excessive ingestion of ice can also cause acute gastric irritation, reflux, and heartburn. Since your body doesn’t recognize caffeine as a significant factor in cold drinks, you may not experience any of these side effects when iced coffee is consumed.

Do hot and iced coffee have any noticeable differences?

There can be a little difference in taste, but the peak of caffeine intensity is about the same for both types of coffee. Total daily intake should be about the same for iced and hot coffee. As with all beverages containing caffeine, moderation is recommended to avoid side effects like insomnia or anxiety.

The Science Behind Poop

A lot of science goes into why we poop, and iced coffee is one of the many things that can influence it. In general, caffeine is a diuretic, which means it increases urine production. When you drink iced coffee, your body must work harder to eliminate the caffeine since it’s no longer processed through the stomach. This can lead to more urine being produced and, eventually, pooping. Another thing that can contribute to pooping after drinking iced coffee is dehydration. When dehydrated, our bodies don’t have enough fluids to function properly, including going to the bathroom. So, even though you’re sure it’s not because you had coffee, drink lots of water before your next iced coffee.

There are other things that can influence our poop ques. It could be the food we eat before drinking the coffee that causes it. Sometimes foods and drinks can cause temporary constipation since they don’t break down properly in our guts as other things do. In many cases, when we eat reasons that might make us poo, we pass them out afterward with no problem at all. If this is the case for you, plan to eat something that doesn’t give you any problems within 24 hours of your coffee!

Possible Causes of Your Problem

A few possible causes of your problem with iced coffee making you poop. One possibility is that the caffeine in iced coffee triggers your body’s natural response to the stimulation.

If you’re experiencing any problems with your bowel movements, it’s important to speak with a doctor about the cause and possible treatments.

How to Manage Your Symptoms

If you’re like most people, you enjoy a cold coffee on a hot day. But for some people, iced coffee can cause an urgent need to go to the bathroom. Here’s why:

Coffee is full of caffeine which can trigger your body to release more urine. If you drink iced coffee on an empty stomach, the caffeine will hit your system faster than if you had it with food in your stomach. This will cause your bladder to contract and produce more urine.


Iced coffee is amazing, but it can also be tricky to adjust. Some people love the intense caffeine rush that iced coffee provides, while others find that their stomach doesn’t seem to handle cold or warm drinks. If you experience bloating and gas after enjoying an ice-cold cup of joe, there may be a simple explanation – your gut isn’t used to digesting cold liquids. To avoid this problem and have the best possible experience with iced coffee, try drinking it gradually over time rather than all at once.
