Children who use antibiotics have a higher incidence of a repeat infection within six weeks then children who don’t use antibiotics. In part this is due to bacteria becoming drug resistant. Another reason is that antibiotics directly injure the immune system.
Antibiotics eradicate beneficial bacteria in our intestines. These bacteria are responsible for proper absorption of nutrients. Substantially reduction of these will lead to malnutrition. This will weaken the body and its immune system. Digestion of metabolic toxins, bacteria, and viruses is greatly reduced.
Because antibiotics promote an alkaline environment they promote growth of pathogenic yeast and fungi. These fungi are directly destructive to the lining of the small intestines and can cause Leaky Gut Syndrome. Here, absorption and protection of the intestinal lining is compromised to the extend where the lining literally becomes perforated. This can cause a wide variety of symptom including chronic fatigue, fibromyalgia, headache, eczema, and others.
Antibiotics also compromise the production of white blood cells. Normally, white blood cells multiply in an infection. This is a normal response of the body to achieve healing. Therefore inflammation and mucus secretion is a natural part of healing. When antibiotics inhibit WBC production, the bodies healing ability is compromised. This period of lowered immunity often allows a re-infection. This is why antibiotics help to reduce sore throat, fever, and phlegm even in a viral infection. But those are only the symptoms and not the cause.
