Many people enjoy drinking Pepsi, but some experience diarrhea after consuming it. While regular Pepsi contains fructose, which can cause diarrhea in large amounts, Diet Pepsi does not contain any ingredients known to cause diarrhea. However, artificial sweeteners in Diet Pepsi and other diet sodas may trigger diarrhea in some individuals. These sweeteners have laxative effects and can pull water into the colon, aiding stool movement. Caffeine in Pepsi may also stimulate the intestines, leading to diarrhea. Assessing your diet and eliminating potential triggers is essential to manage diarrhea effectively.
| Characteristics | Values |
|---|---|
| Artificial Sweeteners | Artificial sweeteners have a laxative effect and are not meant to be absorbed by the body. They pull water into the colon and help to mobilize the stool. |
| Caffeine | Caffeine may stimulate the intestines and increase motility. |
| Carbonation | Carbonation can cause belching, flatulence and indigestion. |
| Intake | Drinking more than 2 cans of Diet Pepsi can cause diarrhea within 30 minutes. |

What You'll Learn
Artificial sweeteners in Diet Pepsi
Artificial sweeteners are often used in diet drinks, such as Diet Pepsi, as a sugar alternative. They are usually far sweeter than sugar, so only tiny amounts are needed to create the same sweet taste. The artificial sweetener used in Diet Pepsi has changed over the years, with the original formulation using saccharin, which was replaced with aspartame in 1983. In 2012, the sweetener was changed to sucralose, but this was unpopular, so Pepsi reverted to aspartame in 2016.
Aspartame is a controversial ingredient that has been linked to a variety of negative health effects. It is much sweeter than sugar, and it has almost no calories. It is sold under brand names such as NutraSweet and Equal. It has been deemed safe for human consumption by regulatory agencies in their respective countries, including the U.S. However, some studies have linked aspartame to an increased risk of metabolic syndrome, which can cause weight fluctuations, heart disease, and stroke. It has also been deemed a 'possible carcinogen' by the WHO cancer agency, due to it causing tumours in animal trials and potentially increasing the risk of cancer in humans.
Other health risks associated with artificial sweeteners include their well-known laxative effects, which can cause digestive distress and chronic diarrhoea, especially when consumed in large amounts. They can also interfere with your sense of taste, as well as cause headaches, cravings, and mood swings.
It is important to note that the health effects of artificial sweeteners are complex and not fully understood. While they may be a better alternative to sugar for some people, excessive consumption may lead to negative consequences. If you are experiencing chronic diarrhoea, it is recommended that you consult a doctor or a dietitian to identify the cause and determine a suitable treatment plan.

Caffeine in Diet Pepsi
Caffeine is a naturally occurring substance found in coffee beans, tea leaves, kola nuts, cocoa beans, and many other plants. It can also be man-made and added to certain beverages to enhance their flavour. Caffeine is commonly found in coffee, tea, chocolate, and sodas, and it can also be present in foods flavoured with coffee or chocolate. It is known to speed up the digestive system and can be the cause of diarrhoea for some people.
Diet Pepsi contains caffeine, with a 12-ounce serving containing approximately 35 to 36.7 milligrams of caffeine. This is slightly lower than the caffeine content in regular Pepsi, which typically has around 37 to 38 milligrams of caffeine in the same serving size. The amount of caffeine in Diet Pepsi is still significant and can have an impact on individuals who are sensitive to caffeine or consume it in large quantities.
The effects of caffeine on the body can vary from person to person. While some people may tolerate it well, others may experience negative side effects such as diarrhoea, headaches, cravings, and mood swings. Caffeine speeds up the digestive system, which can lead to loose stools or diarrhoea, especially when consumed in excess. Additionally, caffeine can have a diuretic effect, causing increased urination and potentially leading to dehydration if fluid intake is not adequate.
The artificial sweeteners found in Diet Pepsi and other diet sodas have also been linked to diarrhoea. These sweeteners, such as aspartame and Ace-K, can have a laxative effect and cause digestive issues, especially when consumed in large amounts. The combination of caffeine and artificial sweeteners in diet sodas may be particularly problematic for some individuals.
If you suspect that Diet Pepsi is causing your diarrhoea, it is recommended to try an experiment by switching to non-caffeinated beverages or choosing a different type of soda. You can also try reducing your overall intake of Diet Pepsi or similar caffeinated and artificially sweetened beverages. It is important to listen to your body and make adjustments as needed to maintain a healthy digestive system.

Diarrhea caused by underlying conditions
Diarrhea is usually a short-term issue that goes away on its own within a few days. However, chronic diarrhea, which lasts for several weeks or keeps coming back, may be caused by underlying conditions such as:
Inflammatory Bowel Disease (IBD)
IBD is an underlying condition that can cause diarrhea. It is an inflammation of the digestive tract, which could be Crohn's disease or ulcerative colitis. Treatment for IBD may include medications, dietary changes, and sometimes surgery.
Irritable Bowel Syndrome (IBS)
IBS is a common functional bowel disorder that can cause diarrhea. It is a chronic condition characterized by abdominal pain, discomfort, and altered bowel habits. Treatment for IBS typically involves dietary changes, stress management, and sometimes medication.
Intestinal Diseases
Underlying intestinal diseases, such as Crohn's disease or celiac disease, can also lead to chronic diarrhea. Celiac disease, for example, is an autoimmune disorder where the ingestion of gluten leads to damage in the small intestine.
Parasitic Infections
Parasites can cause chronic diarrhea, especially when traveling to developing countries or consuming raw or undercooked foods. Antibiotics or antiparasitic medications can be used to treat parasitic infections.
Food Intolerances
Food intolerances, such as lactose intolerance or gluten sensitivity, can also cause diarrhea. Identifying and eliminating the trigger foods from your diet can help alleviate diarrhea caused by food intolerances.
If you are experiencing chronic diarrhea, it is important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.

Diarrhea caused by other foods
Diarrhea can be caused by a number of factors, including diet, underlying conditions, or medication. When it comes to diet, foods that are sugary, fatty, spicy, or fried can cause loose stools or worsen diarrhea. Dairy foods and foods containing gluten can also cause loose stools, especially in those with intolerances.
Sugar stimulates the gut to release water and electrolytes, which loosen bowel movements. Fructose, a natural sugar found in fruit, is one of the biggest offenders, as the body can only digest a certain amount of fructose at one time. Consuming more fructose than the body can handle may cause diarrhea. This is often found in fruits such as peaches, pears, cherries, and apples, or added to foods and drinks such as applesauce, soda, and juice beverages. Artificial sweeteners, such as sorbitol, mannitol, and xylitol, can also have a laxative effect and cause diarrhea, especially when consumed in large amounts.
Fatty foods can cause digestive difficulties, and if not absorbed normally, they can trigger diarrhea. Spicy foods can also cause diarrhea and burning in the rectum, especially if consumed in large amounts. This is due to a chemical called capsaicin, which gives chili peppers their heat and can irritate the lining of the stomach and intestines.
Caffeine is another common cause of diarrhea as it speeds up the digestive system. It is found in coffee, tea, chocolate, and many sodas, as well as foods flavored with coffee or chocolate.
Some people may experience diarrhea due to dairy products if they have lactose intolerance. Lactose intolerance means the body does not have the enzymes to break down certain sugars in dairy, leading to diarrhea. Gluten, a protein found in wheat, barley, rye, beer, and even salad dressings, can also cause diarrhea in people with gluten intolerance or celiac disease.
It is important to note that the causes and cures for chronic diarrhea can be complex, and if changing your diet does not resolve the issue, it is recommended to consult a doctor.

Health risks of drinking diet soda
Diarrhea can be caused by a number of factors, including diet. Foods that are sugary, fatty, spicy, or fried can cause loose stools. Dairy foods and foods containing gluten can also have this effect. Caffeine, which speeds up the digestive system, is found in coffee, tea, chocolate, and many sodas, including Diet Pepsi. Artificial sweeteners, which are present in diet sodas, are known to have laxative effects.
The health effects associated with consuming diet soda are more serious than many people realize. Firstly, artificial sweeteners in diet sodas may cause diarrhea, but only if you drink a lot of soda. The International Foundation for Gastrointestinal Disorders reports that chronic diarrhea is usually due to something in the diet that is consumed in large amounts, especially sugar and chemicals.
Secondly, diet soda can interfere with your sense of taste. A study conducted by researchers at San Diego University found that the brain's reward system in diet soda drinkers was incapable of differentiating between sugar and artificial sweeteners.
Thirdly, diet soda can lead to weight gain. A 2015 study in the Journal of the American Geriatrics Society found that older diet soda drinkers actually gained triple the abdominal fat compared to their peers who didn't consume the drink. Another study found that habitual, long-term diet soda consumption was linked to increased body fat, including visceral fat, and an increased risk of developing obesity.
Fourthly, diet soda can cause metabolic syndrome. A 2016 study published by the Canadian Science Journal revealed that aspartame, the artificial sweetener used in many diet sodas, decreases the activity of certain enzymes in your gut, which can lead to metabolic syndrome, a cluster of conditions that can cause weight fluctuations, heart disease, stroke, and even death. Diet soda increases your risk of metabolic syndrome by more than 30%.
Finally, diet soda can cause cardiovascular complications. A 2021 study found that regularly consuming artificial alternative sweeteners, which are present in diet soda, is associated with a risk of developing cardiovascular complications, including glucose intolerance and type 2 diabetes.
Other health risks of drinking diet soda include an increased risk of a heart attack, high blood pressure, and bone loss.

Frequently asked questions
Artificial sweeteners in Diet Pepsi can have a laxative effect. They pull water into the colon and help to mobilise stool, which can cause diarrhea. Caffeine in the drink may also stimulate the intestines and increase motility, leading to similar results.
The International Foundation for Gastrointestinal Disorders states that more than two or three cups of coffee or tea daily can cause diarrhea. Since Pepsi contains about one-third the caffeine of coffee, you would need to drink about 6 to 9 cups of Pepsi (48 oz to 72 oz) for it to have a laxative effect.
If you suspect that Diet Pepsi is causing your diarrhea, you can try eliminating it from your diet and seeing if the symptoms improve. You can also try non-caffeinated diet soda for a week and see if that makes a difference. If you still experience diarrhea, then it is likely the artificial sweeteners in Diet Pepsi that are causing the issue.
It is important to stay hydrated by drinking plenty of water. Probiotics may also help to reduce IBS symptoms and prevent diarrhea. If your diarrhea lasts for more than 2 days, contains blood, or is accompanied by severe stomach pain, you should contact a doctor immediately.
