The brain and gut connection

Have you ever been so depressed or anxious, that you lost your appetite Zandara download? What is the reason for this? Surely, your body doesn’t need less food than usual when you feel depressed – so why does your mood influence your appetite?

Your brain and your gut are actually very closely linked – many experts have stated that your gut is actually your second brain! What does this mean, you ask? Well, it’s been suggested that an unhealthy digestive system may actually contribute to depression and anxiety. Let’s take a look at how this could be possible.

The ‘gut feeling’

Your body contains over 100 trillion (yes, trillion!) bacteria – before you freak out, these are ‘good’ bacteria that help your body function properly.

According to a Harvard Medical School publication, “The gastrointestinal tract is sensitive to emotion. Anger, anxiety, sadness, elation — all of these feelings (and others) can trigger symptoms in the gut.” [And] A troubled intestine can send signals to the brain, just as a troubled brain can send signals to the gut. Therefore, a person’s stomach or intestinal distress can be the cause or the product of anxiety, stress, or depression.

So, what does all this mean?

Your gut and your brain are essentially one system, meaning that they have an impact on each other.

Here’s another example: have you felt like you’re going to be sick or get abdominal cramps right before you have to make a speech or give a presentation? This feeling of emotion is not “all in your head” – the stress you’re feeling is actually causing physical symptoms.

The Harvard article also says that stress can trigger the following physical and emotional symptoms.
