You know the drill. If your cough has continued for several weeks, your doctor may prescribe a 10-day course of antibiotics. Your lungs will clear up after a few days. Then your stomach revolts. You suddenly develop gut symptoms that make you wish you never had a cough. What else can you do to stop going to the bathroom, other than stop taking the medication and risk relapse?
This is an unfortunate trade-off for an effective drug. Antibiotics are effective in killing infections, but they cannot always distinguish between good and bad bacteria. As they travel through the body, they eliminate beneficial gut bacteria. This can make your digestive tract vulnerable. Then the harmful bacteria take over. For most people, intestinal discomfort is only temporary. Antibiotic-related diarrhea occurs in about 20% of patients.
Stopping antibiotics seems like a logical solution. However, if you stop early, the original infection often returns. This is not a viable treatment. Recent research suggests a better approach. Taking a probiotic along with your prescription can greatly reduce the risk of this gastrointestinal side effect.
Why probiotics can help protect your gut
Why probiotics are so effective is still not fully understood. According to the theory, they maintain balance in the gastrointestinal tract. When antibiotics wipe out the natural microbiome, a vacuum is created. Bad bacteria waiting in the wings rush to fill the empty space. Competition occurs when probiotics are introduced at the same time.
Friendly bacteria compete for space and nutrients. This crowds out the harmful strains before they can take hold. This is a numbers game. Although this drug affects other parts of the body, it actually increases the natural defenses of the gut.
Choosing the right supplements
Dietary sources of probiotics such as yogurt, sauerkraut, and tempeh are healthy. However, they are not effective enough to fight antibiotic-associated diarrhea by themselves. The concentrations are simply too low.
If you want to prevent AAD, you need effective supplements. Look for products that contain at least 5-10 billion colony forming units (CFU). The strains must be viable. While science hasn’t proven exactly which strains fight which harmful bacteria, certain brands have shown promise in studies.
- Saccharomyces boulardii (commonly sold as Florastor)
- Lactobacillus rhamnosus GG (commonly sold as Culturelle)
These specific strains may be effective in keeping the gut stable during treatment.
Continuing the Routine After Treatment
Your gut needs time to recover from the upheaval. Do not stop taking probiotics the day your last antibiotic pill is gone. Continue to use the supplement for several weeks after that.
In some cases, diarrhea may appear only 2-3 weeks after finishing the medication. Your gut is still healing and the microbiome is still rebuilding itself. Quitting smoking too soon exposes your digestive tract to its most vulnerable state.
The science is still evolving when it comes to the long-term effects of gut flora disturbances. But for now, the strategy seems clear. Support your body with the right bacteria during treatment. Monitor the symptoms after. Let your gut heal on its own terms. The cough will go away eventually. The question is, can your stomach handle the war.
