According to a 2011 study in Nature, antibiotics disrupt the metabolic hormones leptin and ghrelin. That effect lasts for at least one year and results in significant weight gain. In another 2012 study, researchers found that British children exposed to antibiotics early in life are more likely to become overweight later in life.
Antibiotics promote thyroid disease, menstrual disorders, and estrogen dominance. Even a few courses of antibiotics can increase the risk of breast cancer by 150 percent.
Antibiotics are a life-saving miracle, but they’re also not great for our hormonal system. Why? Because they disrupt our healthy gut bacteria.
From a hormonal perspective, gut bacteria are supposed to:
- Activate thyroid hormone T4 into its active form T3, and prevent autoimmune thyroid disease.
- Reduce inflammation, which improves the sensitivity of leptin and insulin receptors.
- Enhance absorption of magnesium, which is essential for progesterone production.
- Produce vitamin B12 which is essential for the production of the neurotransmitter dopamine, and the methylation of estrogen.
- Escort estrogen metabolites from the body.
- Support the neurotransmitter GABA and reduce anxiety.
Save the antibiotics for the saving of lives
Antibiotics are a miracle. They save lives, and that is what they are for: Treatment of life-threatening infections. They’re not for feeling a bit better when you have a chest cold. In addition to their bacteria-killing properties, many antibiotics have a slight anti-inflammatory effect, which is why people often feel better when they take them. But there are plenty of other ways to feel better including zinc, fluids and rest.
Taking antibiotics when they’re not needed damages the health of our nervous system, immune system and hormonal balance. Furthermore, it promotes antibiotic-resistance.
Choose antibiotic-free meat
Factory-farmed meat can contain a large amount of antibiotic residue (from the antibiotics given to the animals). Choose animal products that are “antibiotic-free”.
