Consequences of Excessive Antibiotic
Use
Antibiotics do
not just go after the pathogenic or “bad” bacteria. They also
indiscriminately destroy the beneficial bacteria necessary and
vital to good health. Among the more important beneficial bacteria
are lactobacillus acidophilus and bifidobacterium bifidus. They
help protect the body against infection. Depleting these organisms
can disrupt the balance of the body, suppress immunity, and lead to
increased susceptibility to infections by fungi, bacteria, viruses
and parasites. Additionally, when antibiotics are used excessively,
depleting the beneficial bacteria, there may be an overgrowth of
yeast in the body. A yeast infection can suppress immunity, which
may lead to recurrent infections.
What's more,
antibiotics adversely affect many nutrients, particularly the ones
needed by the immune system to fight infection, such as vitamins A
and C. One of the most common side effects of antibiotics is
diarrhea. This causes a loss of nutrients, especially magnesium and
zinc. Some children are on antibiotics for months or even years.
Nutritional loss over such a long period of time is debilitating
for the body and sets up an environment for more infections.
