Why Sugary and Carbonated Drinks Worsen Diarrhea
When dealing with diarrhea, the primary goal is to rehydrate and soothe the digestive system, not aggravate it. Unfortunately, soft drinks like Pepsi do the opposite due to their key ingredients: high sugar content, carbonation, and caffeine.
The high sugar load in Pepsi is particularly problematic. Sugars, especially fructose found in high-fructose corn syrup, can overwhelm the digestive system during a time of illness. When there is an excess of sugar, it pulls additional water into the intestines, which makes watery stools even more frequent and loose. This is counterproductive to recovery and can exacerbate dehydration, a significant risk associated with diarrhea.
Furthermore, the carbonation in Pepsi introduces gas into your gastrointestinal tract. This can cause uncomfortable bloating, gas, and stomach cramps, all of which are unwanted side effects when your stomach is already upset. Some individuals with pre-existing conditions like Irritable Bowel Syndrome (IBS) may find these effects even more pronounced.
For many people, Pepsi and other colas contain caffeine, which acts as a stimulant and diuretic. As a stimulant, caffeine can increase intestinal motility, meaning it makes your bowels move faster. This speeds up the digestive process and can worsen diarrhea symptoms. Its diuretic effect also causes your body to urinate more, which further contributes to fluid loss and increases the risk of dehydration.
The Myth of Flat Soda
Some people recall a folk remedy of drinking flat soda to treat an upset stomach. While it's true that allowing the carbonation to dissipate removes one irritant, the high sugar and potential caffeine content remain. The New York Times reported on a study in which researchers found that sodas, even when flat, contain very low amounts of key electrolytes and far more sugar than recommended for rehydration. The conclusion was clear: flat soda is not a reliable or recommended treatment for diarrhea or upset stomach.
What to Drink Instead of Pepsi
When combating diarrhea, replacing lost fluids and electrolytes is paramount to preventing dehydration, which can become severe if left unchecked. Instead of reaching for a Pepsi, consider these safer and more effective alternatives:
- Oral Rehydration Solutions (ORS): These specialized drinks, such as Pedialyte, have the correct balance of water, sugar, and salts needed to replace lost electrolytes. They are specifically formulated to help the body absorb fluids more efficiently than plain water or sugary beverages.
- Clear Broth: Chicken, beef, or vegetable broth is a great option. It provides sodium and other minerals that are lost during diarrhea, helping to restore electrolyte balance.
- Plain Water: While it doesn't replace electrolytes, water is essential for staying hydrated. Alternating between plain water and electrolyte-rich drinks is a good strategy.
- Ginger Tea: Herbal, caffeine-free ginger tea can be soothing for an upset stomach and provides hydration. You can even make your own by boiling ginger root.
- Diluted, Low-Pulp Juice: For some, a half-water, half-juice mixture can be a tolerable option, but only if it's low-pulp and non-citrus. Apple and grape juice are often recommended, but they should be used with caution due to their sugar content.
Beverage Comparison for Diarrhea
| Feature | Pepsi | Oral Rehydration Solution (ORS) | Plain Water | Clear Broth |
|---|---|---|---|---|
| Sugar Content | High | Low, balanced | None | None |
| Electrolytes | Very low | High (sodium, potassium) | Very low | High (sodium) |
| Carbonation | Present | None | None | None |
| Caffeine | Often present | None | None | None |
| Effect on Diarrhea | Worsens symptoms | Replenishes fluids, aids recovery | Replenishes fluids, dilutes electrolytes | Replenishes fluids and sodium |
| Digestive Impact | Irritating, bloating | Soothing | Neutral | Soothing |
Foods and Habits to Aid Recovery
In addition to what you drink, your diet and habits play a huge role in recovering from diarrhea. Medical professionals often recommend a bland, low-fiber diet, often referred to as the BRAT diet (Bananas, Rice, Applesauce, and Toast), for the first 24-48 hours. Other easy-to-digest foods include boiled potatoes, crackers, and plain chicken.
Conversely, just as you should avoid Pepsi, you should also steer clear of certain foods that can irritate your digestive system further. These include fried or fatty foods, spicy dishes, dairy products (which can be hard to digest during illness), and foods high in insoluble fiber. Rest is also important, as it gives your body the energy it needs to fight the infection or irritation causing the diarrhea. Practicing good hygiene, especially frequent hand-washing, can prevent the spread of infectious diarrhea.
Conclusion: Prioritize Proper Rehydration
Drinking Pepsi is not a recommended or safe practice when you have diarrhea. The high levels of sugar, carbonation, and caffeine found in the soda actively work against your body's recovery, worsening dehydration, increasing intestinal distress, and prolonging your symptoms. Instead of relying on ineffective home remedies like flat soda, prioritize scientifically-backed rehydration methods. Oral rehydration solutions, clear broths, and plain water are your best allies for replacing lost fluids and electrolytes and helping your body heal. By making informed choices about what you consume, you can speed up your recovery and feel better faster. If symptoms are severe or persist for more than a few days, it's always best to consult a healthcare provider for proper guidance.
Additional Considerations and Warning Signs
While home care is often sufficient for a short-term bout of diarrhea, it is critical to know when to seek medical attention. You should contact a doctor if you experience signs of severe dehydration, such as reduced urination, extreme thirst, or lethargy. Other warning signs include a high fever, severe abdominal pain, or blood or mucus in the stool. Infants and young children are at a higher risk of dehydration and should be monitored carefully by a pediatrician. In such cases, intravenous (IV) fluids may be necessary. For chronic diarrhea caused by conditions like IBS or inflammatory bowel disease, tailored medical treatments are required.
