Antibiotics and Your Gut: What You Need to Know
By Harlee Palmer, PA
When you’re feeling sick, it’s common to wonder: “Do I need antibiotics?” While these powerful medications can be life-saving when used appropriately, they can also impact more than just the infection—they can disrupt the delicate balance of your gut microbiome.
When Are Antibiotics Necessary?
Antibiotics are designed to fight bacterial infections, not viruses. That means they’re effective for conditions like strep throat, urinary tract infections, or bacterial pneumonia, but not for common colds or the flu. Overusing antibiotics when they’re not truly needed can lead to antibiotic resistance and unnecessary side effects.
That’s why it’s important to consult with your provider to determine whether antibiotics are the right course of treatment.
Your Gut Microbiome: A Delicate Ecosystem
Your gut is home to trillions of beneficial bacteria that support everything from digestion to immune function and mood. Unfortunately, antibiotics can’t differentiate between “bad” and “good” bacteria, they wipe out both. This disruption can lead to:
- Bloating
- Diarrhea
- Decreased immunity
- Long-term changes in gut health
How to Protect Your Gut During Antibiotic Use
To help your gut recover and maintain balance during a course of antibiotics, consider incorporating these gut-friendly options:
Probiotics
Probiotic supplements can help replenish beneficial bacteria. Look for strains like Lactobacillus and Bifidobacterium, and take them a few hours apart from your antibiotic to avoid interference.
Fermented Foods
Include naturally probiotic-rich foods in your diet, such as:
- Yogurt (with live active cultures)
- Kefir
- Sauerkraut
- Kimchi
- Miso
- Kombucha
These foods can help restore microbial diversity and reduce the risk of gastrointestinal side effects.
Antibiotics are essential in modern medicine, but they should be used thoughtfully. Supporting your microbiome with probiotics and fermented foods can help your body stay balanced and resilient during and after treatment.
