Antibiotics and Probiotics – how to replenish your good bacteria in the gut.

On one hand, antibiotics are very powerful, help kill bacteria and often save lives. On the other hand, they have significant impact on the good bacteria that live in our guts. If you are prescribed a course of antibiotics, what types of things can you do to help replenish your good bacteria? We discuss this in more detail in this blog.

Let’s first discuss antibiotics:

What are Antibiotics and what do they do to your gut bacteria?

An antibiotic is any substance that inhibits the growth of or destroys microorganisms. It’s not always possible to avoid antibiotics, sometimes they required. When they are destroying the bad bacteria unfortunately, they also wipe out the beneficial bacteria

High dose antibiotics and the duration of the course have a greater impact on the good bacteria in the gut. High doses over a prolonged period of time can cause extensive damage that may take years to recover. Likewise, in children their gut flora is established in the first few years and antibiotics can upset their gut flora with detrimental effects. Poor gut health makes them more susceptible to diseases like asthma, eczema and poor immunity. To read more about children;s gut health and probiotics, Read here.

When replenishing good bacteria, it takes time and 3 areas of focus:
