How your Gut Health Affects Anxiety, Depression and Other Mental Disorders

According to the Anxiety and Depression Association of America, about half of people suffering from IBD have anxiety and/ or depression – IBD is the condition of having a sensitive colon, which is easily upset by certain foods and stress.

Our guts contain both Good and Bad bacteria that populate the microbiome. These bacteria live in harmonious unison with the beneficial bacteria preventing the overgrowth of harmful bacteria which can harm our health.

The gut contains trillions of bacteria that aid with digestion and keeping the immune system in check. Our gut bacterium plays a vital role in our overall health. The GI tract is said to be the second brain of the body because it contains tons of nerves, which send signals back and forth to the brain.

However, our gut doesn’t just play a role in our physical health. Brain gut connection anxiety. This is where the gut-brain axis comes into play.

Brain Gut Connection Anxiety

This term refers to the bidirectional communication system between our gut microbiomes and the brain. Simply put; our gut talks to our brain via hormones that are stored in gut cells, immune molecules, and the nerve signals.

Additionally, the brain can also send signals to the gut via our body’s control system, the autonomic nervous system.

This communication channels between these two organs are closely linked in the body. Brain gut connection anxiety, that means the gut’s health has a direct connection to anxiety, depression, and many other mental disorders.

How Gut Health Affects Mental Health

Our gut health is critically involved in regulating our body’s inflammation. Some studies conducted suggested that individuals with mental health disorders such as Parkinson’s disease and autism have unhealthy gut microbes.

The gut bacterium produces two neurotransmitters known as dopamine and serotonin. Gut brain connection depression. These two neurotransmitters play a huge role in mood regulation.

Most people who suffer from anxiety or depression regularly experience gut issues. Irritable bowel syndrome (IBS) is strongly linked to depression and anxiety.

A study conducted in 2007 showed that the gut microbiome is essential to how microRNAs function. MicroRNAs are tiny molecules that affect how we express genes; especially how to control the expression of anxiety genes and other anxious behaviors in the brain.

Another way gut health affects anxiety, depression, and other mental disorders has to do with BDNF. BDNF is a protein that helps with nerve growth in the brain. Low levels of BDNF in the brain play a significant role in psychological disorders such as anxiety and depression.

A study conducted showed that the brain experiences a dip in the protein BDNF levels when the bacterial gut levels are disturbed. When gut health goes back o normal, the BDNF also goes back to normal.

In addition, your bowel movements affect anxiety, depression, and other mental disorders. The gut microbiota that ends up in our feces plays a considerable role in IBD symptoms. However, more research is needed to fully understand the correlation between fecal bacteria transplant and its effect on anxiety.

Altering your gut microbiome can have a significant impact on your mood, as well as various mental health disorders.
