Bloating and HPA Axis Dysregulation: Stress's Impact on Your Gut

Did you know that chronic stress can impact not just your mind but also your gut health? Your body's stress response, controlled by the HPA axis, can influence digestive processes and contribute to bloating. In this article, we’ll explore the signs & symptoms of a dysregulated stress response, as well as some tips on how you can address it to reduce your bloating.

Understanding the HPA Axis and Gut Health

The Hypothalamic-Pituitary-Adrenal (HPA) axis is a vital system that regulates our body's response to stress. When we encounter stressors, the hypothalamus in our brain signals the release of hormones that cascade down to the adrenal glands, which leads to the release of cortisol, one of our key stress hormones. While cortisol serves an essential role in managing inflammation and immune responses, too much cortisol can lead to a whole range of issues including poor gut health, thyroid and hormone imbalances, skin breakouts and poor sleep.

The Gut-Brain Connection: How Stress Impacts Digestion

Your gut is often referred to as your "second brain" for a good reason. It houses millions of neurons and communicates closely with the central nervous system, including the brain.

When stress disrupts the HPA axis, it can lead to several negative effects on our gut health:

• Increased Intestinal Permeability: Chronic stress can compromise the integrity of the intestinal lining, which allows harmful substances like toxins and undigested food particles to leak into the bloodstream, which triggers inflammation and can contribute to bloating.
  

• Altered Microbiota: Stress can alter the composition and diversity of the gut microbiome, the community of microorganisms that reside in our digestive tract. Stress-induced dysbiosis can cause digestive issues and contribute to symptoms like bloating, gas, and irregular bowel movements.

Holistic Approaches to Chronic Stress for Young Adults

If you’re struggling with bloating and are concerned that stress could be a contributing factor, don’t panic as there are lots of tools we can utilise to support you with this:

1. Stress management techniques – Breath-work, time management & organisation, healthy sleep habits, social connection, creative outlets/hobbies and limiting screen time are all incredible ways to regular our HPA axis. Here at Wellness Within, we work with our clients to formulate a stress management plan that suits their unique lifestyle and personal preferences, so that it’s maintainable and achievable!

2. Dietary changes – When our body is dealing with a high stress load, we want to reduce our intake of foods and drinks which increase our cortisol levels – this includes things like coffee, energy drinks and processed foods which are high in refined sugars.

3. Herbal medicine – There are several different herbs which have been shown to have adaptogenic (decreases sensitivity to stressors) and anxiolytic (reduces feelings of anxiety) effects. Some examples of herbs specifically indicated here include: Withania, Passionflower and Siberian ginseng.

4. Nutraceuticals – Certain nutrients, such as L-theanine, Magnesium and Omega 3 can be taken in supplement form to provide a therapeutic effect of regulating our bodies stress response.

5. Pre & probiotics – Certain strains of bacteria, such as Bifidobacterium longum, have been shown to reduce stress-induced gastrointestinal symptoms. Other strains within the Lactobacillus species have been shown to increase levels of GABA, our calming neurotransmitter. By increasing levels of these bacteria strains via consuming pre and probiotics, we can improve our bodies capacity to handle stress and reduce negative gut side effects.

6. Regular exercise – Exercise releases endorphins which are our feel-good neurotransmitter, which helps to mitigate the harmful effects of excess cortisol. Balance is key here though – too much intensive exercise can increase cortisol further, as well as increase air intake, leading to increased bloating. It's therefore important to opt for low-moderate intensity exercises such as swimming, weight training and yoga, and avoid the HIIT classes and intensive training.

7. Seeking further support – It’s okay to ask for help; sometimes we need to speak to a psychologist or counsellor to get a better understanding of how we can better regulate our stress response, especially if we are dealing with a mental health condition or significantly stressful life situations.
