Antibiotics Given to Babies Increase the Chance of Obesity Later

Researchers from the New York University School of Medicine’s Department of Pediatrics have determined that children given antibiotics prior to five months of age have a significantly higher risk of becoming obese later in life.

The researchers studied from a group of 11,532 children born in Avon, UK between 1991 and 1992. They focused on three groups: Those children given antibiotics before six months of age; those given antibiotics between six and 14 months of age, and those given antibiotics between 15 and 23 months of age.

They followed the children for seven years, and reviewed their weight an different periods. They found that children given antibiotics prior to six months of age were 22% more likely to be overweight at 38 months of age.

Furthermore, those babies given antibiotics between the ages of 15 and 23 months of age had a significantly greater risk of being overweight at age seven. The researchers noted that this later relationship was not as consistent as the relationship between antibiotics under six months and weight gain.

The researchers expressed the effect this finding potentially has on public health, and the need for further research to study these effects in more detail: “Given the prevalence of antibiotic exposures in infants, and in light of the growing concerns about childhood obesity, further studies are needed to isolate effects and define life-course implications for body mass and cardiovascular risks.”

While this may be a surprising finding to some, other research has indicated this, as infants born of smoking parents or with greater infections have also been linked with weight gain. Infections related to smoking or otherwise are often treated by pediatricians with antibiotics.

How do antibiotics influence weight gain?

This association between obesity and antibiotics relates directly to the how our gut microbiota affect our digestion. Other research has confirmed that probiotics from the Lactobacillus family affect weight gain.

Lactobacillus gasseri has specifically has been linked to weight loss among both animals and humans considered obese, and Lactobacillus plantarum has been linked to weight loss in animal research.

The key lies in the processing our gut’s probiotics perform on our food. They help digest and restructure food molecules, enabling our food’s nutrients to be better utilized by the body. They will also help neutralize oxidative molecules in our foods – which are associated with inflammation and cardiovascular disease. An example of this is very low-density lipoprotein (VLDL).

This microbial gut processing directly affects our weight, as increased inflammation within the body is associated with weight gain.

I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn ones health around. As I drove home that night, I realized I needed to get this knowledge out to more people. So I began writing about health with a mission to reach those who desperately need this information. The strategies in my books and articles are backed by scientific evidence along with wisdom handed down through traditional medicines for thousands of years.” Case connects with the elements by surfing, hiking and being a beach bum.
