Will probiotics be expelled due to diarrhea?

I have recently been consuming a certain brand of dietary fiber (certified by the health department to increase gut probiotics) for about half a month.
However, yesterday I suddenly experienced abdominal pain and mild diarrhea.
I am worried that I might disrupt the gut microbiota that I have worked hard to cultivate.
Does diarrhea expel probiotics from the body?

Arnold: Hello.
The bacteria in your gut are alive, so they will naturally die off over time.
Therefore, you shouldn't worry too much about their loss.
Of course, diarrhea is a more serious form of loss, but they will regenerate.
Diarrhea is something that cannot be controlled, so it's best to stay positive.
You can continue to supplement with probiotics or prebiotics afterward.
They will also adjust their reproduction on their own.
The prebiotics you mentioned (dietary fiber) create a better environment for bacteria to grow, but they are not actual probiotics (beneficial bacteria).
Therefore, improving the gut microbiota and supplementing with probiotics (good bacteria) is one method, while supplementing with prebiotics (fiber) is another.
You can consider both options.
Wishing you good health and happiness.

More Info

Diarrhea can indeed have an impact on the gut microbiota, including beneficial probiotics. When you experience diarrhea, especially if it is acute, your body is expelling not only harmful pathogens but also beneficial bacteria that contribute to a healthy gut environment. This can lead to a temporary reduction in the population of probiotics in your intestines.

Probiotics are live microorganisms that, when consumed in adequate amounts, confer health benefits to the host, particularly in maintaining gut health. They help in digestion, enhance immune function, and can even influence mood and mental health. However, during episodes of diarrhea, the rapid transit of contents through the gastrointestinal tract can prevent these beneficial bacteria from adhering to the intestinal lining and proliferating, thus reducing their effectiveness.

The extent to which diarrhea flushes out probiotics can depend on several factors:
1. Duration and Severity of Diarrhea: Short-lived, mild diarrhea may not significantly impact the overall population of probiotics, while prolonged or severe diarrhea can lead to a more substantial loss.

2. Type of Probiotics: Different strains of probiotics have varying resilience to gastrointestinal conditions. Some strains are more robust and can survive harsh conditions better than others.

3. Dietary Fiber Intake: Since you mentioned consuming a fiber supplement, it’s important to note that dietary fiber can act as a prebiotic, providing nourishment for probiotics. If your fiber intake is consistent, it may help support the regrowth of beneficial bacteria after a diarrhea episode.

4. Hydration and Electrolyte Balance: Diarrhea can lead to dehydration and an imbalance of electrolytes, which can further affect gut health. It’s essential to stay hydrated and replenish electrolytes during and after episodes of diarrhea.

5. Post-Diarrhea Recovery: After experiencing diarrhea, it can be beneficial to continue consuming probiotics, either through supplements or fermented foods like yogurt, kefir, sauerkraut, or kimchi. This can help restore the gut microbiota balance.

In summary, while diarrhea can flush out some beneficial probiotics, the impact may vary based on the factors mentioned above. To support your gut health after an episode of diarrhea, consider reintroducing probiotics and maintaining a diet rich in fiber. If diarrhea persists or is accompanied by severe symptoms, it is advisable to consult a healthcare professional for further evaluation and management.
