Antibiotics and Their Effects

(This monthly newsletter is brought to you by Science Based Nutrition)

Overuse of antibiotics can not only cause resistance but in the end can potentially do more harm than good. The rates of antibiotic prescription levels are disturbing. Center of Disease Control Researchers found that 833 antibiotic prescriptions were prescribed for every 1,000 people when conducting a new study analyzing a national prescription drug database for 2010.1

Consequently, bacteria have increasingly gained the power to shrug off antibiotics. Resistances to antibiotics are emerging as microorganisms are failing to respond to conventional treatment, resulting in prolonged illness, greater risk of death and higher costs. The Centers for Disease Control and Prevention is tracking at least 20 strains of resistant bacteria.1

One of the most common diagnoses given at a doctor’s office is the upper respiratory infection (URI). It accounts for up to 70% of all antibiotics dispensed.2 However, according to Dr. Carol Kauffman, “most URIs are not caused by the bacteria that antibiotics are designed to fight, they are caused by fungi. So, unless a secondary, bacterial infection presents itself most URIs do not require the use of antibiotics”.2

 While antibiotics are often prescribed to treat bacterial infections, they are not effective against viral infections. Viral infections that should not be treated with antibiotics include:

  • Colds
  • Flu
  • Most coughs and bronchitis
  • Sore throats (except for those resulting from strep throat)

How does frequent use of antibiotics affect the body in the long term? By killing off the healthy bacteria. Every time you swallow antibiotics, you kill the beneficial bacteria within your intestines. When you do so, you upset the balance of your intestinal terrain.

The gastrointestinal tract is the body’s first line of defense in terms of immunity. As intestinal bacteria die, yeast will thrive and grow into large colonies and take over. Yeast overgrowth has been one of the leading causes of leaky gut syndrome (a gastrointestinal disorder that develops in the gut wall) as well as food allergies, fibromyalgia, and irritable bowel syndrome just to name a few.

It’s not just humans that over consume antibiotics. Animals which provide us food (like cattle and pork) are treated with them as well. Tons of antibiotics are fed to American livestock on a daily basis to combat mastitis and other diseases, and increase their weight. Today 80 percent of the antibiotics used in the United States are fed to livestock!3

According to Food and Drug Administration records, antibiotic use on farms grew from about 18 million pounds in 1999 to nearly 30 million pounds in 2011.3 If a single animal in a herd or a flock is diagnosed with an illness, the entire herd receives the medication, usually mixed in with the animals’ feed or water because it would be too expensive to diagnose and treat only certain individuals.4 So imagine the amount of antibiotics in the dairy products that children and adults consume on a daily basis.

So as antibiotics affect bacteria in the intestine, does it impact how nutrients are broken down in the body from certain foods? Authors of a study published by the Journal of the American Medical Association hypothesize that antibiotic effects on the body’s immune response as well as response to inflammation, could be related to the development of cancer. They also correlated that the use of antibiotics combined with a weakened immune system and underlying medical conditions can increase certain cancers.6

What can you do? Natural ways are available for prevention and even treatment during a period where your immune system may need some support.

Probiotics are organisms that are thought to restore the balance of bacteria and they help your body produce vitamins, absorb minerals and aid in the elimination of toxins.  Lifestyle factors may also play a role with a vulnerable gut.

  • Reduce the processed foods and refined foods.
  • Reduce sugar.
  • Partake in stress reduction practices.
  • Chiropractic Adjustments.

By optimizing the deficiencies and toxicities in the body we can build a healthy foundation for maximum health. Let us help you get your body in optimal health today!
