How’s your stress? I often feel like we’re all stressed and that’s the norm. But just because there’s an expectation that we’re feeling stressed doesn’t make it okay. As today’s guest explains, all this stress can have a severe negative impact on your health.

About Rachel Doyle, RD

Rachel Doyle is a Registered Dietitian who helps people overcome digestive issues with the healing power of food and functional nutrition. She works with clients individually and in group programs in her virtual private practice, RAD Nutrition.

With a Master’s degree in Nutrition and additional training in integrative and functional nutrition, Rachel uses gut health principles, the mind-body connection, and functional lab testing to help clients find their root cause and regain control of their health.

Understanding the Common Causes of Gut Problems

In this episode, Rachel delves into some common sources of various gut issues. One that she frequently sees is low levels of stomach acid. When we don’t have enough of it, we’ll have trouble breaking down and digesting food. This leads to a whole host of potential problems, from bloating and reflux to bacterial infections and overgrowth.

Rachel also sees a lot of people with bacterial imbalances, various gut infections, and mineral deficiencies. Many times these problems exist in tandem and can lead to a slew of issues. She explains what to look for if you suspect there’s a problem and steps to take to address it.


The Connection Between Your Gut and Your Stress Levels

In addition to these physical root causes of gut problems, is stress. Stress can come from many sources. Overwork, poor sleep habits, high-intensity exercise, past trauma, environmental toxins, and diet can all cause harmful levels of stress. 

Even though we can’t control all these factors, there are steps that anyone can take to reduce stress in their life. Rachel explains how to start talking to yourself in order to accept that you don’t need to live in a constant state of stress. 

Mindset is often at the center of this healing process. Before you can do anything else, you need to believe that recovery is possible. Sometimes the root of stress lies in the gut itself. By treating gut health and mental health together, Rachel has seen how actual and lasting healing occurs.
