Why Your Stomach Gurgles, Feels Bloated, and Swells Up – Abdominal Bloating

Hello. This is Baengnokdam Korean Medicine Clinic.

Have you ever experienced something like this?

You feel your stomach gurgling, your insides feel full but you can't burp, you constantly feel indigestion, breathing feels difficult, and even when you're still, your belly seems to swell up more and more…

We hear these kinds of statements very often in the consultation room.

“All your tests are normal.”

When patients hear this, it's only natural for them to feel upset or frustrated.

Today, let's talk about the true principles behind this common yet difficult-to-explain symptom: 'abdominal distension' or 'bloating'.

It's not just a simple 'gas' problem

Let's clarify first.

The sensation of 'stomach gurgling' ultimately involves three simultaneous elements: ① rumbling sounds, ② swelling, and ③ discomfort. These three stem from different mechanisms.

Is it due to too much gas? No, in reality, bloating can occur even with less gas than normal.

This is because the digestive system is not merely a 'digestive tube,' but a complex regulatory system where the nervous system, hormonal system, and microbial system are intricately intertwined.

When we eat, three axes work simultaneously for digestion: the autonomic nervous system, gut hormones, and gut microbiota.

If even one of these rhythms is disrupted, bloating can occur. This can happen if you feel overly sensitive even without much gas, if bowel movements slow down causing contents to linger, or if microbes ferment excessively, leading to increased internal pressure.

Bloating operates on 4 pathological axes

The symptom of abdominal distension actually arises from the interplay of 4 axes.

First, the motor axis.

If the intestines fail to contract and push contents properly, food or gas can accumulate. This movement is particularly slowed down by stress or accumulated fatigue, which is known as functional bowel motility disorder.

Second, the sensory axis.

Individuals with highly sensitive intestines may feel 'constricted' or 'full' even from gas levels that others wouldn't notice. This is a state where the sensory nerves of the digestive organs themselves have become hypersensitive.

Third, the content axis, or internal composition.

Typically, when there are many FODMAP foods—i.e., fermentable carbohydrates—microbes produce gas, leading to bloating. Lactose, fructose, and artificial sweeteners are prime examples.

Fourth, the abdominal wall–somatic wall control axis.

When the body is tense or posture is hunched, the diaphragm is compressed, and abdominal space narrows. This prevents gas from dispersing properly, leading to severe pressure. Patients often describe this as feeling unable to breathe.

Because these four axes are intertwined, the causes and mechanisms behind the same 'gurgling' sensation can vary significantly.

Rebound Bloating: When treatment makes it worse

Many people use medications like acid suppressants, gas relievers, or gut motility enhancers because their symptoms are uncomfortable. Initially, they certainly feel better. But strangely, after a few days... the discomfort worsens, and their stomach feels harder.

This is precisely what we call medication-induced rebound, or rebound bloating. A prime example is PPIs, or proton pump inhibitors (a type of acid suppressant).

While suppressing stomach acid offers temporary relief, the body compensates by secreting more of a hormone called gastrin. Then, when the medication is stopped, stomach acid levels surge explosively, leading to exacerbated post-meal bloating, heartburn, and burping.

Another case is the long-term use of digestives or laxatives. The bowel's rhythm relies on its own autonomous movement; constantly stimulating it with medication can impair its self-regulatory function, eventually leading to a state where bloating cannot be overcome without drugs. In such cases, the approach should shift from suppression to restoring the natural rhythm.

Why is Korean Medicine effective?

Korean medicine does not view this symptom as a single substance like 'gas' or 'stomach acid'. Instead, it perceives bloating through flow and circulation-centric pathological concepts such as the circulation of Qi (氣), weakened spleen and stomach function, stagnation of liver Qi, and the formation of 'Damjeok' (phlegm accumulation).

For example, if you easily bloat after meals and burp frequently, it's considered 'Sikjeok' (food stagnation). If it worsens with stress and causes chest discomfort, it's 'Ganul-Giche' (liver qi stagnation). If bloating persists and doesn't subside even when pressed, it's 'Damjeok' (retained phlegm/phlegm accumulation). If your stomach always feels cold, you have poor digestion, and lack energy, it's 'Biheo' (spleen deficiency). In this way, precise pathological interpretation is possible based on the patient's constitution and patterns.

Crucially, treatment involves not just medication, but a holistic approach that addresses symptoms and bodily balance. This includes acupuncture, pharmacopuncture, and moxibustion to promote abdominal Qi and blood circulation, herbal decoctions to restore digestive power and autonomous movement, and, if necessary, adjustment of breathing, posture, and even daily rhythms.

Things you can do yourself

While Korean medicine treatment is beneficial, self-management methods that patients can practice are also very important.

• Chew slowly for at least 20 minutes
• Practice diaphragmatic breathing for 5 minutes after meals, placing a hand on your belly for inhales and exhales
• Try a low-FODMAP diet: limit onions, dairy products, and legumes
• Reduce late-afternoon caffeine and carbonated drinks
• Sit in a posture that opens up both your abdomen and chest
• When feeling chest tightness, switch from shallow breathing to deep diaphragmatic breathing

It's especially helpful to note down, even just one line a day, when your symptoms worsen (time of day), how they progress after meals, and their connection to stress. This significantly aids in determining the treatment direction.

Listen to what your belly is telling you

Abdominal distension isn't just a simple gas issue. It's a signal from your body telling you, 'something's blocked in the flow' or 'my rhythm is disrupted'.

What we truly need to look at is not test results, but what rhythm a person is living in right now. Bloating isn't an enemy to be suppressed; it's a compass guiding us towards recovery. Korean medicine is a system that can read these signals, re-tune them, and restore the flow.

When your stomach gurgles, don't just blame gas. It might be your entire body trying to communicate with you.
