There are several things that can cause diarrhea, including caffeine, sugar and certain artificial sweeteners. Identifying the culprit can help you find relief.

Most people develop diarrhea after consuming too much sugar or fructose. Fructose is a common ingredient in fruit and can also be found in sodas.


Caffeine is a chemical compound that can stimulate the central nervous system, giving you a boost of energy. It also causes your heart to beat faster and can cause jitteriness, so it’s best to keep your caffeine intake to moderate levels.

It can also increase blood pressure, body temperature and blood flow to the skin & extremities. It can also affect stomach acid secretion and production of urine. Some side effects of caffeine include dizziness, troubled breathing, muscle tremors, nausea, diarrhea, increased urine, a fruit-like breath odor, changes in appetite, insomnia and cold sweats.

One cup of coffee usually contains about 200 milligrams of caffeine, which is equivalent to the amount in a 12-ounce can of cola soda. Drinking more than this can cause a number of problems including headaches, anxiety, trouble sleeping and irritability.

Another concern is that it can speed up the process of peristalsis, which is muscle contractions in your intestines that allow food to pass through your digestive tract. This can lead to diarrhea, according to a small study published in 2018.

Other people experience diarrhoea after drinking coffee due to the addition of dairy products or other sugars. This is especially common with lactose intolerance, which makes it difficult for the body to digest dairy products.

If you’re consuming a lot of coffee and it’s causing you to have loose stools, try drinking a decaffeinated version. The decaffeinated version does not contain as much caffeine as the regular version, so it’s less likely to cause you to have diarrhea.

The high acidity of coffee can also cause gastrointestinal problems, so it’s important to drink water with your coffee. You can also add a bit of milk to your coffee to help avoid diarrhoea and other gastrointestinal issues.

In order to avoid diarrhea after consuming caffeine, make sure you have a balanced diet that includes plenty of vegetables and fruits. It’s also a good idea to drink lots of water during the day to help your digestive system function properly.


Fructose is a type of sugar that comes from many foods, including fruit and vegetables. It is also found in sugar-free beverages and processed foods that contain artificial sweeteners.

When the body can’t break down fructose properly, it passes through the gastrointestinal tract as undigested waste molecules that get fermented by bacteria in the colon. This causes bloating, gas, abdominal pain and stomach cramping. In some cases, it is a trigger for Irritable Bowel Syndrome (IBS) symptoms.

Hereditary fructose intolerance occurs when there is a genetic mutation that makes the aldolase B enzyme in the liver work improperly. This enzyme is used to convert stored sugar into usable energy. If you have hereditary fructose intolerance, eating high-fructose foods can lead to serious health problems such as liver disease and kidney stones.

If you are diagnosed with hereditary fructose intolerance, a diet low in processed sugars and high in whole grains will help to prevent your condition from worsening. Avoid sugary drinks like soda, juices and fruit juices. Instead, eat plenty of fresh fruits and vegetables. Steaming cooked veggies helps to keep them from losing much of their vitamins and nutrients.

Symptoms of hereditary fructose intolerance can vary from person to person, but most people with the condition experience bloating, diarrhea and abdominal discomfort. This is similar to the symptoms of lactose intolerance or irritable bowel syndrome, but in addition to that, people with hereditary fructose intolerance will also have trouble absorbing other nutrients.

Some people with fructose intolerance can also have trouble absorbing sorbitol, a type of sweetener found in pome fruits. Sorbitol and fructose share the same transport proteins, so when they’re consumed together, sorbitol blocks the transportation of the fructose from your small intestine to your colon. Sorbitol then gets stuck in your colon and enters your bloodstream.

It’s important to remember that fructose and sorbitol both have an osmotic effect, which means that they are drawn into the colon with lots of water. Bacteria in the colon quickly ferment these left over fructose molecules, which produce noxious gases such as hydrogen and methane.

Sugar alcohols

Sugar alcohols, which include sorbitol and mannitol, are commonly found in lower-sugar candies and protein bars. They are lower in calories and carbohydrates than sugar, which means they help you maintain a healthier weight.

The main concern with consuming too much of these sweeteners is that they can cause diarrhea. This happens because your digestive system can’t fully absorb them. It can also occur if you eat a large amount of them at once.

Xylitol and erythritol are two types of sugar alcohols that can cause loose stools or diarrhea in some people. This is especially true when you consume them in large amounts or for a long period of time. The American Diabetes Association recommends that you don’t eat a lot of these sugar-free products, especially if you have a condition that can make you sensitive to certain substances.

Sorbitol, the most common type of sugar alcohol, is less likely to cause diarrhea than other kinds of sugar alcohols, because it’s not as easily digested by your body. However, it’s still important to keep track of your diet to avoid consuming too much of it.

Other types of sugar alcohols can cause bloating and gas. These symptoms are more pronounced in some people who have a digestive disorder, such as irritable bowel syndrome or celiac disease.

If you have any GI symptoms after eating foods with sugar alcohols, you should stop the consumption immediately and see a doctor. This can help reduce the severity of your symptoms and improve your quality of life.

Another problem with sugar alcohols is that they can promote the growth of bacteria in your intestines, which can lead to diarrhea and other problems. This may happen because the sugar alcohols act as a food source for these bacteria.

It’s also possible for sugar alcohols to cause you to gain weight, which is a problem for people who are trying to lose weight or who have diabetes. This is because these sweeteners contain carbs, which can impact your blood glucose levels. It’s best to consult a registered dietitian to learn more about how sugar alcohols fit into your overall meal plan and how to limit their consumption.

Artificial sweeteners

If you are trying to lose weight or have diabetes, artificial sweeteners can make it easier for you to eat foods that are low in sugar. But they can also cause problems if you consume too much of them, especially the artificial sweeteners that are found in diet sodas and other drinks.

Some artificial sweeteners can cause diarrhea in people who have trouble absorbing fructose or sorbitol, two common types of artificial sweeteners. Fructose is a type of sugar that occurs naturally in fruits, but your body can only digest a certain amount at one time. So consuming too much of these sugars can cause bloating, gas and diarrhea.

Other kinds of sweeteners, like sucralose and stevia, don’t seem to cause diarrhea. They’re safe for most people, but if you have a condition that causes you to get irritable bowel syndrome or another digestive disorder, you should avoid them completely.

Researchers at Ben-Gurion University of the Negev (BGU) have discovered that certain artificial sweeteners can change the makeup of the bacteria in your gut microbiota, which regulates your body’s digestive process and overall health. These bacteria help you absorb nutrients from the foods you eat, and they also communicate with each other to keep your gut healthy.

However, the artificial sweeteners used in diet sodas and other foods have changed the way these bacteria work. The sweeteners, such as saccharin and aspartame, are thought to suppress the good bacteria in your intestines, allowing harmful bacteria to take over.

As a result, the bad bacteria can grow out of control and lead to a variety of digestive problems, including diarrhea. These symptoms can also cause an increase in water and nitrogen gas in your colon, which can lead to constipation.

If you’re looking for a way to reduce your consumption of artificial sweeteners, you should consider adding more natural sweeteners such as honey or maple syrup into your daily diet. These are less likely to cause gastrointestinal problems, and they are also lower in calories than artificial sweeteners.
