Although antibiotics are essential to treat bacterial infections, they also eliminate beneficial bacteria from the intestine. This can result in digestive side effects such as nausea and diarrhea.

This difficulty is highlighted by Dr. Trisha Pasricha in the publication of her column in The Washington Post, where she clarifies that the recovery of the microbiota is possible, but it may be more complicated than many believe.

So much so that he takes on the task of debunking myths such as those about probiotics, reported by the media outlet La Tercera after observing the article.

Probiotic Supplements: A Potential Myth

Pasricha warns that there is no conclusive evidence that probiotic supplements are effective in recovering the microbiota. A recent meta-analysis indicates that its use during antibiotic administration has minimal effect. Some studies even suggest that these supplements may delay the recovery of the original gut microbiome.

A study in Nature Medicine, carried out in Sweden, revealed that certain antibiotics, such as clindamycin and some fluoroquinolones, can cause permanent changes in the microbiome, prolonging the alteration of the intestinal flora for years.

Recommendations to strengthen the microbiota

The specialist advises avoiding supplements and focusing efforts on more effective eating habits. It highlights the importance of a high-fiber diet and the inclusion of fermented foods, such as Greek yogurt and kimchi, to promote microbial diversity and reduce inflammatory markers in the blood.

A Stanford clinical trial shows that people who ate more fermented foods had a more diverse microbiota and less inflammation, supporting Dr. Pasricha's recommendations.

Responsible use of antibiotics

The gastroenterologist emphasizes that, despite the possible adverse effects on the intestinal flora, antibiotics are critical in medical treatment.

It underlines the importance of using them only when absolutely necessary and of always completing the prescribed treatment to prevent bacterial resistance.

Natural alternatives to recover the microbiota

The most effective natural alternatives to recover the microbiota after antibiotics are based on consuming natural probiotics (foods with live bacteria) and prebiotics (fiber that feeds good bacteria).

Fermented foods (natural probiotics):

Prebiotic foods (fiber to feed bacteria):

Other important habits:

These foods provide live microorganisms that help repopulate the intestine, although their effect may be limited compared to clinical probiotics in severe cases. The combination of probiotics prebiotics (symbiotics) enhances the effects of both.
