Depression and gut health.  Did you know that there is far more serotonin in your gut than in your brain?  The May 2017 issue of Gastroenterology contains a study showing a possible link between gut health and mood.  In fact the study found a very strong link between digestive inflammation and depression.  In a double blind placebo study, subjects who took supplements for digestive health showed sizable mood improvements over the placebo control group.

It’s important to remember that your body needs serotonin not only for mood but for digestive health as well.  Additionally, many of you will remember the multitude of articles I’ve released showing the gut-brain connection.  In fact experts now refer to the gut as the second brain, since it actually contains more nerves than the spinal cord.  Furthermore, the gut also has outbound nerves.  This means it may have the ability to command other organs and tissues. Clearly there is a strong connection between gut health and brain function.

Our Approach

Your brain and digestive function are a direct result of your digestive health. And while I don’t diagnose or treat any disease (including depression), I can help support healthy digestion.  And of course this can support healthy mood. This, in turn, promotes healthy brain function. I provide this support with a specific plan. And this plan usually includes custom dietary changes and the correct enzyme supplements. Of course I only make recommendations after scientific testing based on sound medical principles.

Are you concerned about digestive health or mood? Do you spend hours or days at home waiting for your problems to subside? Are you missing out on work family or fun? If so, you can contact us one of several ways to set up a consultation. You can reach us on the web, stop by our office in Redmond, WA, or call us at 425-868-0120. Then I will personally sit down with you and talk about your suffering and how it affects your life. I will even do some preliminary testing as well as Bio Impedance Analysis (BIA). In fact did you know that both NASA and Cancer Treatment Centers of America rely on BIA? These tests help me determine if you are a good candidate for care. If you’re not, we’ll make every effort to provide the proper referral.
