Rumbling in the stomach and loud borborygmi often prompt people to assume "spleen-stomach deficiency cold" and reach for red dates, longan, and ginger tea in turn. Yet strangely, some people become more bloated the more they tonify, and their borborygmi grow even louder. How does traditional Chinese medicine view this contradiction? The key lies in the fact that borborygmi are not necessarily a sign of deficiency—they may also signal a disturbance in the movement of qi.
The Small Intestine Meridian and the Hand Shaoyang Sanjiao Meridian: The Meridian Code Behind Borborygmi
Rumbling in the stomach and loud borborygmi are clinically most often seen in imbalances of the Hand Taiyang Small Intestine Meridian and the Hand Shaoyang Sanjiao Meridian. The Small Intestine Meridian runs along the posterior border of the lateral aspect of the arm and corresponds to 1–3 p.m. (the Wei hour), when qi and blood flow into the small intestine, which is responsible for separating the clear from the turbid. If the small intestine's separating function is impaired, water and fluids mix with waste, producing sounds within the intestinal tract. The Sanjiao Meridian, by contrast, runs along the midline of the lateral aspect of the arm and corresponds to 9–11 p.m. (the Hai hour), governing the body's qi movement and water-fluid pathways. When Sanjiao qi transformation is impaired and water-dampness stagnates in the stomach and intestines, gurgling sounds likewise arise. These two meridian problems require entirely different approaches to regulation.
The key acupoint of the Small Intestine Meridian is Zhizheng (SI 7), located on the dorsal aspect of the forearm on the ulnar side, 5 cun above the dorsal wrist crease. Zhizheng belongs to the Hand Taiyang Small Intestine Meridian and is the luo-connecting point of this meridian, diverging to the Heart Meridian. The Lingshu · Jingmai records: "The divergence of the Hand Taiyang is called Zhizheng, 5 cun above the wrist, internally connecting to Shaoyin." This point serves as the hub communicating qi and blood between the Small Intestine Meridian and the Heart Meridian, and is theoretically linked to the small intestine's function of separating the clear from the turbid. For the Sanjiao Meridian, the commonly used point is located 2 cun above the dorsal wrist crease, between the two bones. This is Waiguan (SJ 5), which belongs to the Hand Shaoyang Sanjiao Meridian, is a luo-connecting point, and is one of the eight confluent points, communicating with the Yangwei Vessel. The Lingshu · Jingmai states: "The divergence of the Hand Shaoyang is called Waiguan, 2 cun from the wrist, externally winding around the arm, entering the chest, and joining the pericardium." Waiguan is where Sanjiao meridian qi passes through, corresponding to the Sanjiao's functions of presiding over qi transformation and facilitating water-fluid passage. These acupoints require a licensed TCM practitioner to determine the stimulation protocol based on individual constitution; they must never be self-administered at will. When using moxibustion or acupressure on such points, a professional physician will make a comprehensive assessment based on pulse and tongue presentation.
From the perspective of time-based health maintenance, the Wei hour (1–3 p.m.) is suitable for rest, avoiding strenuous activity that could interfere with small intestine digestion. Excessive fatigue or consumption of cold and raw foods during this time can aggravate borborygmi. The Hai hour (9–11 p.m.) should be devoted to relaxing body and mind to facilitate smooth Sanjiao qi movement. Clinically, in people who habitually stay up late or are under great stress, borborygmi problems are often related to Sanjiao meridian disharmony, and simple warming tonification may instead worsen qi stagnation.
Distinguishing Qi Stagnation from Water-Fluid Retention: Two Directions in Borborygmi Pattern Differentiation
Rumbling in the stomach and loud borborygmi clinically require first distinguishing whether qi stagnation or water-fluid retention predominates. In qi stagnation-type borborygmi, the sounds are high-pitched and intermittent, often accompanied by abdominal distension and belching, worsening with emotional fluctuations. These individuals typically have a thin white tongue coating and a string-like pulse. If rich, cloying substances such as red dates and longan are used at this point, they may instead obstruct qi movement, leading to "more bloating the more one tonifies."
Water-fluid retention-type borborygmi is different: the sounds are low and continuous, like water sloshing in a bag, often accompanied by epigastric stuffiness, a bland taste in the mouth without thirst, and loose stools. The tongue coating is mostly white and slippery or white and greasy, with a soft, slow pulse. If such individuals blindly use warming tonification, water-fluid retention may increase, and borborygmi may worsen. Traditional Chinese medicine holds that "water flowing through the intestines with a splashing sound" is precisely the typical manifestation of internal water-fluid retention.
The two types frequently overlap in clinical practice. Some individuals have both qi stagnation and water-fluid retention, presenting with borborygmi that vary in pitch and coexisting abdominal distension and stuffiness. In such cases, the treatment approach must address both moving qi and transforming fluids, without neglecting either. A licensed TCM practitioner, through comprehensive analysis of the four diagnostic methods, can more precisely determine which aspect predominates and thereby formulate a personalized plan.
Diet and Daily Routine: Everyday Considerations for Managing Borborygmi
Rumbling in the stomach and loud borborygmi are more commonly seen in people with long-term irregular eating habits or a preference for cold and raw foods. These individuals often also experience cold intolerance in the epigastrium and a preference for warm drinks. However, it should be noted that not all borborygmi are related to cold. Clinically, if some individuals simultaneously present with dry mouth, bitter taste, and a yellow greasy tongue coating, this may belong to internal accumulation of damp-heat, in which case simple warming tonification is inappropriate, and the focus should instead be on clearing heat and transforming dampness.
From the perspective of seasonal nodes, borborygmi is more prone to flare up during the long summer season (the sixth lunar month). At this time, dampness is at its heaviest, and the spleen-stomach's transportation and transformation functions are easily encumbered. Appropriately adjusting dietary structure—reducing greasy and sweet-cloying foods and choosing light, easily digestible ingredients—can help alleviate borborygmi to some degree. For example, moderate consumption of spleen-fortifying, dampness-draining ingredients such as coix seed and white hyacinth bean may be helpful, but these should be used under a physician's guidance, as these ingredients are cool in nature and not suitable for everyone.
Regarding daily routine, eating too late at night or eating too much can affect the Sanjiao Meridian's qi transformation function, leading to worsened nighttime borborygmi. It is recommended to schedule dinner at least 3 hours before bedtime and to eat only to about 70% fullness. Drinking warm water on an empty stomach in the morning helps some people, but those with excessive gastric acid or gastroesophageal reflux should not blindly follow this practice.

Frequently Asked Questions
Q: What is the difference between borborygmi and diarrhea? Why do I sometimes need to rush to the toilet right after borborygmi?
Borborygmi are sounds produced by the movement of gas and fluid within the intestines and constitute a symptom; diarrhea refers to increased frequency of bowel movements with loose stools and constitutes a sign. The two often occur together but have different mechanisms. The immediate urge to defecate after borborygmi suggests hyperactive intestinal peristalsis or downward pouring of water-dampness, which may be related to spleen deficiency with exuberant dampness or liver qi attacking the spleen.
Q: Why is it that for the same stomach rumbling, some people respond to qi-regulating herbs while others respond to dampness-transforming herbs?
This depends on constitution and disease mechanism. When qi stagnation predominates, moving qi reduces borborygmi; when water-fluid retention predominates, transforming dampness eliminates borborygmi. If qi stagnation is accompanied by dampness obstruction, then both moving qi and transforming dampness must be used together. Traditional Chinese medicine emphasizes "treating the same disease with different methods," precisely because of such individual differences. Generic protocols without pattern differentiation often yield limited results.
Q: Are borborygmi related to emotional stress? Why do they worsen when I am nervous?
Traditional Chinese medicine holds that the liver governs free coursing and regulates the movement of qi. Long-term anxiety, tension, or depression can lead to liver qi stagnation, which then attacks the spleen, disrupting spleen-stomach qi movement and aggravating borborygmi. Clinically, such individuals often present with chest and hypochondriac distension and frequent sighing. Treatment should address both soothing the liver and fortifying the spleen, rather than focusing solely on the intestines themselves.
