Question

When you take antibiotics to treat bacterial infections, you often develop diarrhea and secondary infections as a consequence (or side-effect) of the antibiotic therapy. Why, do you think, that happens?

Answer 1

This is because they disrupt the normal microflora present in our digestive system and other parts of the body.

Antibiotics are molecules that are used against life. They are used to treat pathogenic infection in living organisms like we use antibiotics to treat Salmonella typhi which causes typhoid in human beings.

Whenever we take such antibiotic, they kill the pathogenic microorganisms but they also affect the normal microbiota of our body.

In most of the cases, they affect the digestive system therefore our stomach gets upset and we feel nauseatic as well. But in case the microflora of a skin is disrupted then we get rashes and inflammation on the skin and itchiness as well.

Antibiotic molecules do not kill the microbes present in normal microbiota like the kill pathogenic microbes, but they disturb the normal concentration of these microorganisms in our body which leads to side effects.
