Bloating is one of those complaints that can be surprisingly difficult to describe.

For some people, it feels like a little extra fullness after eating. For others, the abdomen becomes visibly distended and uncomfortable, with pressure, wind or a feeling that food is simply sitting there. It may be worse after particular foods, towards the end of the day, or during times of stress.

In Chinese medicine, there isn’t one single explanation for bloating.

The important question is not simply “How do I stop bloating?”, but “Why is this happening?”

Different patterns can produce very similar digestive symptoms, and this is one reason Chinese medicine takes an individual approach to digestive complaints.

Bloating and the Spleen

In Chinese medicine, the Spleen has an important role in transforming and transporting the food and fluids we consume.

When Spleen Qi is functioning well, digestion and the movement of food and fluids are relatively smooth. When the Spleen is weak, this process can become less efficient.

A person with Spleen Qi deficiency might experience bloating after eating, tiredness, loose stools, a feeling of heaviness, reduced appetite or a tendency to feel particularly sluggish after meals.

The bloating may not necessarily be dramatic. It can simply feel as though the abdomen is slow to settle after eating.

This is one reason why Chinese medicine doesn’t necessarily recommend the same treatment for everyone with bloating.

When Stress Affects Digestion

Another common pattern involves the relationship between the Liver and the digestive system.

In Chinese medicine, the Liver is associated with the smooth movement of Qi. When Qi becomes constrained, digestion can be affected.

This is particularly interesting when bloating seems to change according to a person’s emotional state.

Some people notice that their digestion becomes worse when they are stressed, frustrated, anxious or under pressure. They may experience abdominal distension, trapped wind, belching or a sensation of fullness which comes and goes.

The bloating may also move around rather than remaining in exactly the same place.

This can be associated with what Chinese medicine calls Liver Qi stagnation.

It is one of the reasons that an acupuncturist may ask questions about stress and emotional wellbeing when someone comes for treatment for a digestive complaint. This isn’t because the symptoms are imagined or “all in the mind”. Rather, Chinese medicine has traditionally recognised an intimate relationship between emotional tension and the movement of Qi through the digestive system.

Why Some People Feel Bloated After Eating

The timing of bloating can be useful information.

If bloating occurs almost immediately after eating, an acupuncturist might consider a different pattern from someone who feels increasingly distended several hours later.

Likewise, it matters whether the bloating improves after passing wind or having a bowel movement, whether it is worse after particular foods, and whether warmth makes it better or worse.

Other symptoms can also provide clues.

For example:

• Is your appetite strong or weak?
• Are your stools loose, hard or variable?
• Do you feel tired after eating?
• Do you tend to feel cold?
• Does stress make your digestion worse?
• Does the bloating improve after passing wind?
• Is your abdomen tender or uncomfortable to touch?
• Do you feel better after eating or worse?
• Is the bloating worse at a particular time of day?

These details may seem unrelated, but in Chinese medicine they help build a picture of the underlying pattern.

Bloating Isn’t Always Caused by What You Just Ate

It is tempting to look for a single food responsible for bloating.

Sometimes there is indeed an obvious dietary trigger. But persistent bloating can be more complicated than simply identifying a “bad” food.

Two people can eat exactly the same meal and experience completely different digestive symptoms.

Chinese medicine therefore looks not only at what someone eats, but also at how well their digestive system is able to process it.

This is an important distinction.

Rather than asking only which foods should be eliminated, treatment may focus on improving the underlying digestive function.

The Importance of Qi Movement

Another way of thinking about bloating in Chinese medicine is through the movement of Qi.

The digestive system needs movement. Food needs to be transformed and transported; fluids need to be distributed; waste needs to be eliminated.

When this movement becomes constrained, a person can experience a sensation of fullness, distension or pressure.

This is why acupuncture treatment for bloating may sometimes involve points that don’t appear to have anything to do with the abdomen.

Treatment is based on the pattern rather than simply the location of the symptom.

Tong Xin Yao Fang and Digestive Complaints

Some of the principles used in Chinese medicine for digestive complaints are quite subtle.

Tong Xie Yao Fang, for example, is a formula that can be understood in relation to the movement of Qi and the relationship between the Liver and the digestive system. It is one of the formulas discussed in more detail in [my article on Tong Xin Yao Fang].

This is also why understanding Dui Yao — the traditional pairing of herbs to produce particular therapeutic effects — can be useful when looking at Chinese herbal medicine.

However, a formula should not be chosen simply because someone has bloating.

Bloating is a symptom, rather than a diagnosis in itself. The same symptom can arise from quite different underlying patterns.

What Can You Do About Bloating?

There are some simple things worth paying attention to before trying to make dramatic changes to your diet.

Try noticing:

When does the bloating occur?
Immediately after eating? A few hours later? Towards the end of the day?

What makes it better?
Passing wind? Having a bowel movement? Eating? Resting? Gentle movement? Warmth?

What makes it worse?
Stress? Large meals? Particular foods? Eating quickly?

What other symptoms occur alongside it?
Changes in appetite, bowel movements, energy levels, sleep or mood may all be relevant.

Keeping a short record can sometimes reveal a pattern that is difficult to notice from memory alone.

And if bloating is persistent, severe, new or accompanied by other concerning symptoms, it is important to discuss it with your GP or another appropriate healthcare professional. Chinese medicine can be used alongside conventional medical care, but persistent digestive symptoms should not simply be assumed to be a Chinese medicine pattern.

Looking at the Whole Person

One of the things I find interesting about treating digestive complaints with Chinese medicine is that the symptom itself is only the beginning of the conversation.

Two patients can both say, “I feel bloated,” while having completely different presentations.

One may be tired, cold and prone to loose stools. Another may be tense and stressed, with bloating that comes and goes throughout the day. Someone else may have a very different pattern again.

Chinese medicine attempts to understand these differences rather than treating the word “bloating” as though it were a single condition.

For an acupuncturist, the aim is therefore not simply to make the abdomen feel less distended. It is to understand why the digestive system is behaving in this particular way, and to treat the underlying pattern as part of the person as a whole.

If bloating is something you experience regularly, an acupuncture consultation can provide an opportunity to look at the digestive symptoms alongside your general health, energy, sleep, emotional state and other symptoms — rather than considering the bloating in isolation.
