Antibiotics Can Change You Forever

So if you have a weak immune system, the first thing you have to fix is your gut. There was a medical study that found that if you take an antibiotic drug for four days, they went and retested the gut microbiome six months later, and there were many species and strains of probiotics in your gut that still hadn't returned. So sometimes when you take antibiotics, you permanently kill certain types of bacteria and yeast that you need to be healthy, and many of them never return. The other stat we know is 70 to 80% of your immune system is found in your gut microbiome.
