How do antibiotics affect the intestinal flora?

The job of antibiotics is to kill bacteria. Basically, every antibiotic specializes in attacking one or more specific bacteria. However, an antibiotic never works so precisely that it attacks a single bacterial strain and leaves everyone else alone. Accordingly, antibiotic therapy always reduces the number of beneficial bacteria.

The effect is even more severe with so-called broad-spectrum antibiotics: A doctor prescribes broad-spectrum antibiotics if the exact pathogen is unknown or has already developed resistance. Since these drugs have a very broad effect, many "good" bacteria usually die in the process.

Missing intestinal bacteria - so what?

It may be hard to imagine, but if your intestine lacks some important bacteria, then nothing will run smoothly.

Numerous complaints can be the result of an imbalance in the intestinal flora after antibiotic therapy.
Some examples are:

  • diarrhea
  • constipation
  • bloating
  • vitamin deficiency


  • a weakened immune system
  • inflammations in the intestine
  • food intolerances
  • psychological disorders
You see, a disturbed intestinal flora can cause discomfort all over the body.

Build up of intestinal flora after taking antibiotics

If you need to take antibiotics, it is always a good idea to give your intestinal flora a helping hand. After taking antibiotics for a short time, your intestinal flora usually regenerates itself. However, if it hasn't been completely balanced before or if the antibiotic has drastically reduced several useful bacterial strains, the intestinal flora can have a difficult time.

Especially with the right diet you can help your intestinal flora during and after antibiotic therapy. Take as little sugar, alcohol and easily digestible carbohydrates as possible. Eat plenty of fibre, vegetables, fruit and yoghurt or kefir. This way, your good bacteria receive a lot of food.

With probiotic food supplements you can additionally support your intestines during and after taking antibiotics. In addition, this prevents you from causing more damage in the first place. Because probiotic bacterial cultures contain several bacterial strains at the same time, which are sometimes difficult to supply with food.
