Summary

Every time you pop an antibiotic, you think you're winning the battle, but what if you're quietly losing the war? Sure, antibiotics can be lifesaving. But in our modern times, antibiotics are often prescribed for everything… even when they make no difference at all.

Most people never stop to ask: Do I really need this antibiotic? Or better yet: What studies show this will actually help my condition?

And ultimately, we never stop to ask what happens after the infection clears. The truth is, that the prescription your doctor handed you may have saved you from one problem while creating a much bigger one you won't see coming for months — or even years.

In this episode, I'm pulling back the curtain on what antibiotics are really doing to your gut, why the damage goes far deeper than you've been told, and what you can actually do about it if you've ever taken one, or a hundred.

On this episode, you’ll learn:

Why you should think twice before filling that next antibiotic prescription (00:06)
What Stanford researchers say about getting your gut bacteria back after a course of antibiotics (03:47)
What your gut bacteria have to do with your immune system (03:55)
Why conditions like eczema, psoriasis, and mystery rashes may actually be your gut waving a red flag (05:15)
Exactly what to ask your doctor before you accept a broad-spectrum antibiotic prescription (08:00)
The top tips for rebuilding your gut after antibiotics (it isn't as simple as taking a probiotic!) (12:10)
All about the shocking amount of antibiotics found in meat (14:53)
The real reason your pet may be suffering from itchy skin (17:53)

1:18.6	Antibiotics, when they were introduced in the late 1940s, early 1950s, were considered,
1:25.6	you know, a godsend, and let's not beat around the bush. They saved lives
