Can Antibiotics Start Autoimmunity & Lead To Thyroid Disease?

Excessive use of Antibiotics depletes the healthy bacteria in the gut. Some people use it very frequently even for normal cold flu. If we don't have enough good bacteria in the gut, nutrient absorption will be compromised. For many cases, this results in overgrowth of fungus or overgrowth of bad bacteria in the small intestine. Overall it directly compromises the gut lining and can lead to autoimmunity.
