Antibiotics-KidneyStones

It's not just one class of oral antibiotics, but five that have been identified as risk factors for this painful condition. And that's on top of research showing how antibiotics may make you more prone to this gut-related disease and malignancy and even Parkinson's Disease. This is due to their harsh effects on your microbiome.

The association is most pronounced among younger children, and remains statistically significant for up to five years after exposure, except for broad-spectrum penicillin.

Between 1997 and 2012, the annual incidence of kidney stone disease rose by 16 percent. The highest increase was seen in 15- to 19-year-olds, among whom the incidence rate increased 26 percent per five years.

Previous studies have found an association between oral antibiotics and inflammatory bowel disease (IBD) and colorectal cancer, likely due to disruption of the gut microbiome.

Fluoroquinolones, frequently prescribed for upper respiratory infections and urinary tract infections (UTIs), have been linked to an increased risk for aortic dissection (tears in the aorta), which can be fatal.

According to research published in the Journal of the American Society of Nephrology (JASN) in 2018, oral antibiotics are a risk factor for kidney stones. Health records for 13 million children and adults in the UK were reviewed, showing that exposure to five classes of oral antibiotics was associated with kidney stones within three to 12 months post-use. The adjusted odds ratio of kidney stones was:

1.27 for broad-spectrum penicillin.

1.67 for fluoroquinolones.

1.70 for nitrofurantoin/methenamine.

1.88 for cephalosporins.

2.33 for sulfas.

The association was most pronounced among younger children and remained statistically significant for up to five years after exposure. The authors concluded that, “Oral antibiotics associated with increased odds of nephrolithiasis [kidney stones], with the greatest odds for recent exposure and exposure at younger age. These results have implications for disease pathogenesis and the rising incidence of nephrolithiasis, particularly among children.”

Kidney Stones in Children Are on the Rise

If this link is true, then we’d expect to see rising rates of kidney stones in young patients, and that’s precisely what we’re seeing. As reported by NBC News on July 8, 2023, data show kidney stones are “now occurring in younger people, particularly among teenage girls,” and “diets high in ultraprocessed foods” and “increased use of antibiotics early in life” are thought to be among the key contributors to this trend.

Between 1997 and 2012, kidney stones during childhood doubled.

According to research4 published in the Clinical Journal of the American Society of Nephrology in 2016, between 1997 and 2012, the mean annual incidence of kidney stone disease across age groups increased by 1 percent annually, from 206 to 239 per 100,000 persons.

The highest increase was seen in 15- to 19-year-olds, among whom the incidence rate increased 26 percent per five years. Within this age group, the incidence was 52 percent higher among girls. In men, kidney stones became more common after age 25. According to the authors:5

“These changes in incidence resulted in doubling of the risk of nephrolithiasis during childhood and a 45% increase in the lifetime risk of nephrolithiasis for women over the study period.”

Oral Antibiotics Associated With Inflammatory Bowel Disease

As noted by the JASN authors,6 previous studies have found an association between oral antibiotics and inflammatory bowel disease (IBD), which is thought to be due to a disruption of the gut microbiome.

In May 2022, research7 linking oral antibiotics and IBD was presented at the Digestive Disease Week conference in San Diego, California. Here, the researchers analyzed the health records of more than 2.3 million older adults, aged 60 to 90, who were part of the Danish National Patient Register and the Danish National Prescription Register.

On average, the use of antibiotics was associated with a 64 percent increased risk of developing IBD, and the risk increased with additional doses.8 Compared with those who had taken no antibiotics in the previous five years

One prescription for antibiotics was associated with a 27 percent increased risk of IBD.

Two prescriptions increased risk by 55 percent.

Three prescriptions increased risk by 67 percent.

Four prescriptions increased risk by 96 percent.

Five or more prescriptions increased risk by 236 percent.

Adults who had been prescribed antibiotics one to two years prior to IBD diagnosis had the highest risk. And, while all classes of antibiotics were associated with increased IBD risk, fluoroquinolones, which include brand names Cipro and Levaquin, had the strongest association.10

Interestingly, a very recent study that was just published found that niacinamide may be very useful in the treatment and prevention of IBD11 by converting to NAD+ as a cofactor to produce more ATP in the mitochondria. I have written two reviews that discussed the many other benefits of niacinamide to increase NAD+.

Fluoroquinolones Linked to Fatal Heart Condition

Fluoroquinolones, which are frequently prescribed for upper respiratory infections and urinary tract infections (UTIs), have also been shown to harm your heart. In December 2018, the U.S. Food and Drug Administration (FDA) issued a safety announcement12 about fluoroquinolones after four studies linked the antibiotic to an increased risk of tears in the aorta (aortic dissection), which can be fatal.13

The aorta is the main artery in your body supplying oxygenated blood to your circulatory system. The artery comes from the left side of your heart and runs down the front of your backbone. The review by the FDA found fluoroquinolone antibiotics increase the risk of rupture following an aortic aneurysm (i.e., enlargement of the aorta to more than 1.5 times its normal size).

The finding led the FDA to caution against the use of fluoroquinolone antibiotics in those at risk unless there are no other treatment options available. Specifically, the antibiotic should not be used by:

Those at risk of aortic aneurysm.

Those suffering from peripheral atherosclerotic vascular disease or high blood pressure.

The elderly.

Those with Ehlers-Danlos syndrome or Marfan syndrome (genetic disorders).

Antibiotics Linked to Colorectal Cancer

Researchers have also linked the use of antibiotics to an increased risk of colorectal cancer. As reported by Live Science in 2014.

“Researchers looked at the medical records of more than 22,000 colorectal cancer patients in the United Kingdom, and followed them for an average of six years. The researchers compared the amount of antibiotics the patients had taken at least six months before being diagnosed with cancer, to the amount of antibiotics taken by a group of about 86,000 healthy people.

After controlling for known risk factors for colorectal cancer—including obesity, diabetes, smoking and alcohol consumption—the results showed people who had taken antibiotics, including penicillins, quinolones and metronidazole, were 8% to 11% more likely to develop colorectal cancer, through the effects of the drug on colon bacteria ruining the Microbiome of the gut.

A 2016 study also concluded that the use of antibiotics was associated with an increased risk of colorectal cancer, especially when used frequently, and research published in 2017 found that women who had used antibiotics for two months or more were at an increased risk of developing colon polyps, which can be a precursor to colorectal cancer.

Those who used the drugs for a total of at least two months in their 20s and 30s had a 36 percent increased risk of polyps compared to those who did not, and women who used them for at least two months in their 40s and 50s had a 69 percent increased risk.

Antibiotics Fuel Chronic Disease by Decimating Your Microbiome

In the article written, "The New Endagered Species: The Human Gut Microbiome” reviewed the documentary “The Invisible Extinction,” which highlights the work of microbiologists Dr. Martin Blaser and Gloria Dominguez-Bello, who are investigating the links between chronic diseases and the loss of bacterial diversity in the human gut.

Overuse of antibiotics is a major driver of this loss. Elective C-sections and processed foods also contribute to the destruction of our microbiome. According to research published in the Cleveland Clinic Journal of Medicine in 2018, Americans have already lost half of their microbial diversity, which is why the risks of antibiotics must be carefully weighed against the benefits prior to use.

Protect and Support Your Microbiome

Seeing how the destruction of your microbiome with antibiotics can contribute to kidney stones, this is another area to pay close attention to. Consider the following to protect your microbiome as much as possible:

Eat plenty of fermented foods: Healthy choices include lassi, fermented grass-fed kefir, natto (fermented soy) and fermented vegetables.

Take a probiotic supplement: If you don't eat fermented foods on a regular basis, a probiotic supplement can be useful.

Boost your soluble and insoluble fiber intake, focusing on vegetables and seeds, including sprouted seeds.

Get your hands dirty in the garden: Exposure to bacteria and viruses in soil can help strengthen your immune system and provide long-lasting immunity against disease.

Open your windows: Research shows opening a window and increasing natural airflow can improve the diversity and health of the microbes in your home, which in turn benefit you.18

Wash your dishes by hand instead of in the dishwasher: Research has shown washing your dishes by hand leaves more bacteria on the dishes than dishwashers do. Eating off these less-than-sterile dishes may decrease your risk of allergies by stimulating your immune system.19 Additionally, many dishwasher detergents have dangerous chemicals so if you do use detergent be careful to select a nontoxic one.

Avoid

Antibiotics, unless absolutely necessary. If you do use them, make sure to reseed your gut with fermented foods and/or a high-quality probiotic supplement.

Foods that are high in oxalates.

Conventionally-raised meats and other animal products that are non-organic.

Chlorinated and/or fluoridated water: This includes during bathing or showering.

Processed foods: Excessive sugars, along with otherwise "dead" nutrients, feed pathogenic bacteria. Food emulsifiers such as polysorbate 80, lecithin, carrageenan, polyglycerols, and xanthan gum may have an adverse effect on your gut flora.

Agricultural chemicals: Glyphosate is a widely used herbicide that and could potentially kill many of your beneficial gut microbes if you eat foods contaminated with it.
