Understanding the Link Between Yogurt and Diarrhea
When diarrhea strikes, the balance of bacteria in your gut is often disrupted. This imbalance can be caused by infections, antibiotics, or other gastrointestinal issues. Probiotics, the "good" bacteria found in certain foods like yogurt, can play a significant role in helping to restore this microbial balance.
The Probiotic Advantage
Yogurt that contains "live and active cultures" is a source of beneficial probiotics that can help fight against the harmful bacteria causing diarrhea. Research has shown several potential benefits:
- Shortens Duration: A review of clinical trials found that probiotics can shorten the duration of infectious diarrhea.
- Prevents Antibiotic-Associated Diarrhea: Taking probiotics alongside antibiotics can help reduce the risk of diarrhea, as antibiotics often kill off both good and bad bacteria in the gut.
- Soothes Chronic Conditions: For those with conditions like irritable bowel syndrome (IBS) or ulcerative colitis (UC), probiotics may help manage diarrhea symptoms.
The Importance of Choosing the Right Yogurt
Not all yogurts are created equal, and the type you choose is critical when dealing with an upset stomach. The wrong kind can introduce too much sugar or lactose, potentially making your symptoms worse.
Best practices for choosing yogurt during diarrhea:
- Look for 'Live and Active Cultures': The label should explicitly state this to ensure you are getting beneficial probiotics.
- Choose Plain and Unsweetened: Excess sugar can exacerbate diarrhea symptoms. Avoid fruit-flavored or sweetened yogurts.
- Consider Lactose-Free or Non-Dairy Options: For individuals with lactose intolerance, consuming dairy yogurt can worsen diarrhea. Opt for dairy-free probiotic yogurts made from coconut, almond, or soy milk instead.
- Check CFU Count: For maximum effectiveness, some experts recommend a yogurt containing at least 10 billion colony-forming units (CFUs) per serving.
Potential Risks and Side Effects
While probiotic yogurt is generally beneficial, there are scenarios where it could be detrimental. The main risk factor is lactose intolerance, a common condition where individuals have difficulty digesting lactose, the sugar in milk. In these cases, consuming dairy yogurt can lead to gas, bloating, cramping, and increased diarrhea.
Another consideration is that not all yogurt strains are equally effective for treating diarrhea. Some store-bought yogurts may not contain the specific strains or enough CFUs to provide a therapeutic effect.
Comparison of Yogurt Types for Diarrhea
| Yogurt Type | Pros for Diarrhea | Cons for Diarrhea | Ideal For | Notes |
|---|---|---|---|---|
| Plain, Probiotic Dairy | Restores gut flora, may shorten illness duration | Contains lactose, which can worsen symptoms in some | Individuals with healthy lactose tolerance | Look for varieties with at least 10 billion CFUs. |
| Plain, Lactose-Free | Removes lactose risk, contains beneficial probiotics | Can be higher in sugar, depending on the brand | Those with lactose sensitivity or intolerance | Read labels carefully to check for added sugars. |
| Plain, Non-Dairy (e.g., coconut, almond) | Completely lactose-free, contains added probiotics | May lack the same probiotic profile as dairy versions | People with confirmed lactose intolerance or dairy allergy | Check for live cultures and adequate CFU count. |
| Sweetened/Flavored Yogurt | Tastes better, which can be tempting | High sugar content can worsen diarrhea | Avoid completely during a bout of diarrhea | Sugars can pull water into the intestines, increasing symptoms. |
Alternative and Complementary Dietary Strategies
In addition to potentially consuming the right kind of yogurt, managing diarrhea effectively involves a broader dietary approach. Sticking to bland, easily digestible foods can help soothe your digestive system and firm up loose stools.
BRAT Diet Plus:
- Bananas: Provide potassium and pectin to help firm stool.
- Rice: White rice is a low-fiber, binding food that's easy to digest.
- Applesauce: A cooked, low-fiber fruit option.
- Toast: Simple, white bread is recommended over high-fiber whole grains.
- Other Bland Foods: Consider plain crackers, boiled potatoes, or cooked, peeled vegetables.
What to Avoid:
- Fatty and Fried Foods: Can be difficult to digest and aggravate symptoms.
- High-Fiber Foods: While healthy normally, too much fiber can worsen diarrhea.
- Sugary Drinks and Sweets: High-fructose corn syrup and artificial sweeteners can have a laxative effect.
- Caffeine and Alcohol: Both can have a dehydrating and stimulating effect on the gut.

Conclusion
Is it safe to eat yogurt during diarrhea? The answer is nuanced, depending heavily on the type of yogurt and your individual digestive health. For many, consuming plain, low-sugar yogurt with live and active probiotics can be a helpful strategy to restore gut balance and shorten the duration of symptoms. However, if you are lactose intolerant, dairy-based yogurt can make matters worse, and a lactose-free or non-dairy probiotic alternative is a much safer choice. As always, listen to your body, and if symptoms persist or worsen, consult a healthcare provider.
Frequently Asked Questions
What type of yogurt is best to eat during diarrhea?
Plain, low-sugar yogurt with live and active cultures is best. Look for specific probiotic strains like Lactobacillus rhamnosus or Saccharomyces boulardii which are known to be effective against diarrhea.
How does yogurt help with diarrhea?
Probiotics in yogurt help replenish the beneficial bacteria in your gut, which can be depleted during a bout of diarrhea. Restoring this balance can aid in better digestion and may help reduce the severity and duration of symptoms.
Can yogurt make diarrhea worse?
Yes, if you have lactose intolerance, the lactose in dairy yogurt can worsen diarrhea, bloating, and gas. Also, yogurts high in sugar can pull more water into your intestines, aggravating symptoms.
What are some good non-dairy yogurt options for diarrhea?
If you are lactose intolerant, choose non-dairy probiotic yogurts made from almond milk, coconut milk, or soy, ensuring they contain live and active cultures and are low in sugar.
How soon can I expect to feel better after eating probiotic yogurt?
While individual results vary, some studies suggest that probiotics may help shorten the duration of diarrhea within 24 to 48 hours. Consistency is key.
Are all yogurts probiotic?
No, not all yogurts are probiotic. Some yogurts undergo a heat-treating process after fermentation that kills the beneficial bacteria. Look for the phrase "live and active cultures" on the label to ensure it contains probiotics.
What should I do if my diarrhea doesn't improve with yogurt?
If your diarrhea persists for more than a few days, is severe, or is accompanied by other symptoms like fever or blood in your stool, it is important to contact a healthcare provider. Yogurt is a supplement, not a cure for all causes of diarrhea.
