Letting Go: The Large Intestine, Emotional Release, and Metabolic Health

Sometimes the weather keeps us stuck inside. A blessing in disguise! It's time for a declutter...letting go!

In East Asian medicine, the large intestine is responsible not just for physical elimination (which is why we discus digestion and bowel movements) but, also for emotional release. As the paired organ of the lungs in the Metal element, the large intestine plays a crucial role in the ability to let go—both in terms of physical waste and unresolved emotions. This is deeply tied to the concept of the Po, or corporeal soul, which is associated with the lungs and governs our connection to the physical body and the present moment.

When emotions such as grief, regret, or attachment are not processed, they can become stuck, leading to imbalances in the large intestine. This can manifest as digestive issues like constipation, bloating, or irregular bowel movements. Western medicine also recognises the gut-brain connection, where emotional stress directly affects bowel function, gut microbiome health, and overall metabolism. Chronic stress can lead to irritable bowel syndrome (IBS), inflammation, and a weakened immune system.

Supporting the Large Intestine for Emotional & Physical Well-Being

1. Diet & Hydration for Smooth Digestion – Eating fibre-rich foods such as root vegetables, whole grains, and fermented foods supports regular elimination and gut microbiome balance. Hydration is also key, as both TCM and Western medicine recognise that dryness in the colon can lead to sluggish digestion and toxin buildup.

2. Acupuncture & Breath-work for Emotional Release – Acupuncture targeting the large intestine meridian can help regulate digestion and encourage the release of stored emotions. Deep breathing exercises, which support lung function, also indirectly aid the large intestine by promoting relaxation and reducing tension in the abdominal area.

3. Movement & Letting Go Practices – Engaging in gentle movement, such as Tai-chi, walking, Qi-gong or yoga, can encourage both bowel regularity and emotional processing. From a Western perspective, exercise stimulates peristalsis (the movement of the intestines), while mindful movement practices can help reduce stress hormones that negatively impact digestion.

4. Decluttering & Emotional Cleansing – In East Asian medicine, the large intestine’s function of letting go extends beyond digestion. Decluttering physical spaces, journaling, or engaging in therapeutic conversations can help release emotional stagnation. Neuroscience also supports this idea—studies show that engaging in mindful reflection and externalising emotions can help regulate stress responses and improve overall mental health.

By addressing both physical and emotional aspects of elimination, we create space for renewal. Supporting the large intestine with mindful lifestyle choices allows us to move forward with clarity, resilience, and balance.
