People take antibiotics to clear bacterial infections. However, taking antibiotics for a long time is linked to a higher risk of death.
According to the Scientists, the use of antibiotics is linked to changes in microorganisms that reside in our digestive tract.
The first thing microbes like fungi and bacteria must battle in order to thrive is not the humans to which they can be so deadly, but each other.
And left to their own devices, scientists say, the varying strains of these microbes tend toward balance. In any given hospital or human, plot of soil or livestock yard, strains of bacteria and fungi exist that are helpful, harmful or have no discernible impact at all.
However, when humans have identified microbes as dangerous like the bacteria that cause pneumonia in people, anthrax in livestock or leaf blight in crops, or the fungi that infect people and animals with ringworm or plants with leaf rust we’ve used chemicals and medicines to stymie those microbes.
We’ve worked wonders to reduce the cost and difficulty of crop and livestock production, and to increase the health and lifespan of humans.
But by depressing the population of microbial organisms humans are fighting, we also have eliminated competition for other microbes that are now on the rise, and we have pushed organisms toward mutations that make them resistant to our medicines
People should always talk with a doctor if antibiotics cause bothersome symptoms.
