Although gas, bloating and belching can happen for a whole variety of reasons, it has also been reported as a symptom of anxiety. You may also feel a heaviness or uncomfortable fullness in your stomach.
Why Can Anxiety Cause Bloating?
As with a lot of physical symptoms of anxiety, the triggers lie within our caveman brain. This is the survival-driven part of our brain that our newer, rational cortex grew on top of. Its primary concern is keeping us alive, so when our brain perceives a threat, it releases the stress chemicals cortisol and adrenaline and activates the stress response called the fight, flight or freeze response.
The stress response causes your body to suppress digestion and digestive enzymes, which can lead to issues with digestion, resulting in bloating and excess gas and belching.
If you experience stress and anxiety frequently, you can develop chronic stress, also known as hyperstimulation, which is when your stress response is on high alert for a prolonged period of time, long after the perceived threat has passed. Hyperstimulation can cause prolonged digestive system disruptions, which can lead to chronic bloating and other related symptoms.
How Can I Stop This Symptom?
As this symptom stems from our fight, flight or freeze response, the main thing that we can do to combat it is to focus on our breathing, adopting anxiety-reducing breathing techniques, such as controlled diaphragmatic breathing or box breathing. This should calm our central nervous system, distract our mind from the perceived threat, and deactivate our fight, flight or freeze response allowing our rational brain to kick back in and regain a semblance of control and feel the anxiety lift.
Though this will help short-term, in order to prevent the symptoms of anxiety and stress occurring in the first place, you need to manage or build strategies to tackle your anxiety and stress. There are several options available including CBT (Cognitive Behavioural Therapy), mindfulness, medication and group therapy. If you’re unsure, please contact your GP for more information.
Bloating and related symptoms can also be caused by other factors, so talk to your doctor to find the root cause and therefore the best course of action.
