OYGH Series: TCM for IBS

OYGH Series: TCM for IBS

Irritable bowel syndrome (IBS) refers to a disruptive colon motility where large intestines are affected, characterized by abdominal bloating, cramps, or pain, and often accompanied with either an increased or reduced frequency in bowel movement and Traditional Chinese Medicine (TCM) has shown to be effective in managing IBS discomforts naturally. 

In Singapore, it is surprising to know 1 in 10 suffers from IBS[1], a common functional gastrointestinal disorder affecting especially the younger crowds as we see a rising trend in individuals aged between 20-30. As IBS cannot be definitively diagnosed through standard tests, it is advisable to consider a blood test and stool test to rule out infection and inflammatory bowel disease (IBD), the latter refers to the inflammation or destruction of bowel wall that bring about the narrowing of intestines. Though many individuals may present with mild degree of IBS symptoms, those who have suffered from chronic IBS over a prolonged period experience impaired quality of life as it causes grave disturbance to their daily routine at work or at rest.

Currently, there is no cure for IBS as most conventional medicine is used to manage and relieve the clinical symptoms of IBS.

Common IBS clinical presentation: 

  • Abdominal discomfort: Abdominal bloating, cramps, or pain – not relieved by flatulence or after bowel movement. 
  • Changes in appearance and frequency of your bowel movement  
    Diarrhea – soft, loose, or watery stools, at least 3-5 times a day 
    Constipation – hard and dry stools, fewer than 3 bowel movement per week 
  • A sensation of incomplete bowel clearance 
  • Rectal bleeding 
  • Iron deficiency anemia 
  • Weight loss 
  • Feeling depressed and/or anxious in chronic IBS patients 

Brain-gut connection 

One of the most studied pathophysiology involves the understanding between gut-brain axis (GBA) connection. The brain and gut share a unique intertwined relationship that will impact our physical and emotional well-being through the continuous bidirectional signaling and feedback between the central and enteric nervous system, the limbic system with peripheral intestinal functions[2]. Intensive research has been constantly conducted and studied to understand the complex relationship between brain and the gut as this ensures proper maintenance of our gastrointestinal homeostasis.  

When we are stressed, our brain send out signals to the gut via activation of hypothalamus pituitary adrenal (HPA) system to release cortisol from the adrenal gland and prevent effective digestion from taking place as the body initiates the sympathetic system and prepares itself for a fight and defense mode. Henceforth, you may have noticed someone with IBS whom you know is anxious or sensitive, habitually experiences butterfly moments, running to the washroom right before an important interview, presentation, or examination. The intimate relationship between the brain and gut is consequential to our overall gut health system. 

Gut microbe changes 

There are recent advances to reveal the interaction between intestinal microbiota and GBA through bidirectional channels signaling from the gut-microbiota to brain and from brain to gut-microbiota via neuroendocrine-immune pathway. Alterations of intestinal microbiota such as the presence of small bowel bacterial overgrowth (SIBO) are observed in IBS patients who often experience IBS after intestinal infection or an antibiotics treatment[3]

Traditional Chinese Medicine (TCM) on IBS 

From a TCM perspective treating IBS, the interaction between the Shen (mind) and the digestive organs which include the spleen, stomach, intestines, reflects the relationship between brain-gut axis. The Spleen and Stomach are responsible for breaking down and transforming food sources to nutrients for energy uptake and nourishment in the whole body. The small and large intestines control the assimilation of essential nutrients and excretion of waste out of the body. 

Spleen deficiency is prevalent syndrome for most IBS patients which include abdomen bloating, pain and/or cramps, loose bowel or constipated and usually feel sluggish or fatigue. Interestingly, spleen is linked to the worry emotion and thoughts in the mind. When one is disturbed mentally or emotionally, e.g., feeling stress, worried, and unsettled, this inevitably results in the discord between Shen and Spleen. The intriguing relationship between Shen and digestive organs is highly demonstrated by studies and observed clinically in IBS patients who present with depression and/or anxiety behavior. Therefore, while attending to improve the Qi and function of the digestive organs, we must take into consideration how to regulate the Shen. 

Acupuncture and TCM herbs on IBS 

Research has shown that acupuncture in IBS patients stimulates the somatic nervous system and the vagus nerve thereby altering visceral sensation and motility in the intestines [4]. This encourages the parasympathetic system to take place, calms and soothes the spastic intestines while allowing the body to digest, rest and recover. 

Besides abdomen bloating, pain associated with alteration in stool frequency and appearances, there are syndrome differentiations to consider in our IBS TCM treatment for acupuncture and Chinese herbal medicine prescription. The most common syndrome differentiations of IBS in a review [5] include stagnation in Liver energy, Spleen deficiency, Spleen-Stomach weakness, Spleen-Kidney Yang deficiency. For example, an IBS patient with Spleen Qi deficiency usually exhibits fatigue, low metabolism, a lack of motivation and constantly overthinking, worrying, and feeling anxious, swollen fat tongue with teeth markings on the side for tongue diagnosis.
