Leaky gut can cause an unhealthy gut and insomnia.
Leaky gut, also called intestinal permeability, means the lining of your gut wall has been damaged.
To explain leaky gut, imagine that your gut wall looks like a zipper. The teeth of the zipper act as a barrier. They stay close together and don’t let anything through. If the zipper teeth get damaged and broken, then air and dirt can get in and the zipper doesn’t work properly.
➡️ It’s the same with your gut wall. When your gut wall is damaged and has gaps between the cells, undigested food particles, toxic waste products and bacteria leak through the gut wall and enter the bloodstream.
These toxins cause lots of inflammation, day and night. Whenever there’s inflammation, your body releases cortisol. When cortisol is released at night, it suppresses melatonin and wakes you up when you want to be asleep.
✨ The best way to find out for sure what’s going on in your gut is to do a GI (gastrointestinal) Map. This stool test shows what pathogens, opportunistic bacteria and beneficial bacteria live in your digestive system and tests for leaky gut as well.
But leaky gut is just one possible reason for trouble sleeping and digestive issues. There are so many more!
