Why are antibiotics at risk for being ineffective?

The Bacteria in your body are fought everyday by your antibodies most of the infectious bacteria is already strong enough to fight your own immune system, this is where antibiotics(fighting bacteria) come from. When introduced to a new antibiotic you bady adjusts it to your antibodies and fights hard against the bacteria soon it kills it off. After recieving the same antibiotic over and over the bacteria finds a weakness and starts to fight back. eventually it learns to adapt the antibiotic to itself and fight it off completely. There for it becomes usless to use this antibiotic anymore as it is just making the bacteria stronger.

The antibiotics can be classified into three different groups they surely kill the bacterias well if u ask for the antibiotics for to be ineffective that depends person to person individually u see every person has a differnt body and not exactly the same there are many beauty products even they don't effect every one and to some they even cause irritation
by the way the beauty products were just an example

Antibiotics only kill off the weakest of any bacteria, and there will always be some that will survive. The stronger bacteria that survive will reproduce and resistance to that particular antibiotic will become inherant in future strains. This is infact how bacteria mutates, or a better term, "evolves" and adapts to it's environment. Only the strong survive.
It's just like with people: not all of us died during the great flu pandemic of 1918, or the bubonic plauge, and there are some people who are resistant to the HIV virus. There will always be survivers who will live on and pass there resistance to future generations.
This is why we need to learn how to not abuse/overprescribe antibiotics, and to keep developing new ones.

Mutation is a form of evolution. In anti-biotic resistent bacteria, most of the first generation bacteria is destroyed by the medication. The surviving bacteria reproduce. The second generation bacteria is now better able to resist the medication. This cycle will repeat until all the bacteria is resistent.

In any colony of bacteria there will be those few that are resistant to the antibiotic. The more you take them, the stronger the resistant colony will get. Sometimes you just have to let the immune system do the work.

Yes. Bacteria adapt to their surroundings, which explains why medicine is always evolving.
