Just Finished Antibiotics? Here’s What Happens to Your Gut

Antibiotics are sometimes necessary and in many cases, life-saving.
But what most people aren’t told is that the recovery doesn’t always end when the course does.

If you’ve recently finished antibiotics and noticed bloating, changes in bowel habits, skin flare-ups, fatigue or even shifts in mood, you’re not imagining it. These changes are common and they’re often linked to what antibiotics do to your gut microbiome.

Let’s talk about why.

Antibiotics don’t just target harmful bacteria

Antibiotics work by killing bacteria that cause infection.
The challenge is that they don’t discriminate.

Alongside harmful bacteria, antibiotics can also reduce beneficial gut bacteria, the microbes involved in digestion, immune regulation, nutrient absorption and communication with the nervous system.

This is why people often feel “off” after a course, even when the original infection has cleared.

Why symptoms can linger after antibiotics

Your gut microbiome is complex and highly individual.
When it’s disrupted, recovery can take time.

After antibiotics, the gut may temporarily have:

• Reduced microbial diversity

• Lower levels of beneficial bacteria

• An imbalance between protective and opportunistic microbes

For some people, this shows up as bloating or irregular bowel movements.
For others, it might be skin changes, food sensitivities, fatigue or mood shifts.

Supporting your gut after antibiotics

Post-antibiotic gut recovery isn’t about taking everything at once.
It’s about creating the right conditions for your microbiome to stabilise and rebuild.

For many people, this includes:

• A whole-food diet rich in fibre to support digestion and bowel regularity

• Polyphenol-rich plant foods (such as berries, extra virgin olive oil, green tea, dark chocolate and colourful vegetables) to help beneficial gut bacteria regrow and diversify

• Gentle lifestyle support, including adequate sleep, stress management and regular movement

• Targeted, strain-specific probiotics when appropriate to support microbiome balance

Why food alone isn’t always enough (at first)

Whole foods and fibre are foundational for gut health, but after antibiotics, diet alone may not always be enough to restore the bacteria that were reduced.

This is where targeted probiotic support can be helpful, especially when it’s strain-specific and evidence-based.

Not all probiotics are the same

One of the most common misconceptions is that all probiotics do the same thing.

In reality, probiotic benefits are strain-specific. Different strains support different functions, including digestive comfort, immune health, skin health and stress response.

What matters most is:

• The specific strains used

• Whether they’ve been studied in humans

• The dose and formulation

More isn’t always better. The right strains matter far more than the number on the label.

A gentle reminder

Antibiotics are an important part of modern medicine. But recovery doesn’t always stop with the last tablet.

Understanding what happens to your gut after antibiotics and supporting it properly can have a huge difference to your overall health over time.
