Have you ever experienced this troubling pattern: you run to the toilet several times a day, yet each bowel movement is disappointingly small, and you always feel like you haven't fully emptied your bowels? In traditional Chinese medicine (TCM), this is considered a type of "abnormal defecation," though many people mistake it for diarrhea or constipation. So, what exactly does frequent bowel movements with small volume each time reflect about your body? And how should we understand it from a TCM perspective?
Why Does Frequent Bowel Movements with Small Volume Occur?
According to the basic theories of TCM, the formation and excretion of stool are closely related to the functions of the spleen, stomach, large intestine, and small intestine. The spleen governs transportation and transformation, responsible for converting food into refined nutrients; the stomach governs receiving and holding, performing initial digestion of food; the large intestine governs conduction of waste, responsible for excreting feces. When these organ functions become disordered, the phenomenon of frequent bowel movements with small volume each time may occur. For example, spleen deficiency leads to weakened transportation and transformation, causing water-dampness to accumulate internally and affecting stool formation; while impaired qi movement may disrupt intestinal peristalsis, resulting in increased frequency but insufficient output.
From the perspective of meridians and collaterals, Zusanli (ST36) is an important acupoint for regulating spleen and stomach function. Zusanli, also known as Xialing or Sanli, is located on the anterolateral aspect of the lower leg, 3 cun below Dubi (ST35), one finger-breadth from the anterior crest of the tibia. It belongs to the Foot Yangming Stomach Meridian and serves as the He-Sea point of the Stomach Meridian and the Lower He-Sea point of the Stomach. The Lingshu records: "When pathogenic factors are in the spleen and stomach, the disease manifests as muscle pain... all are regulated by Zusanli." This acupoint is closely related to the spleen's function of transportation and transformation and the stomach's function of receiving and holding, and is an experiential acupoint frequently mentioned in TCM when understanding digestive system functions.
Is This Problem "Diarrhea" or "Constipation"?
Many people are confused: does frequent bowel movements with small volume each time count as diarrhea? In TCM pattern differentiation, diarrhea usually refers to loose, unformed stools with significantly increased frequency and larger volume; while constipation refers to difficult defecation with dry, hardened stools. Your situation may fall somewhere in between, which TCM often describes as a manifestation of "tenesmus" — the sensation of needing to defecate but with difficult evacuation. Licensed TCM practitioners frequently encounter this type of patient in clinical practice, who often present with accompanying symptoms such as abdominal distension, fatigue, or poor appetite. So, what might be the possible underlying causes?
Tianshu (ST25) is closely associated with intestinal defecation function. Tianshu, also known as Changxi or Gumen, is located on the abdomen, level with the center of the umbilicus, 2 cun lateral to the anterior median line. It belongs to the Foot Yangming Stomach Meridian and serves as the Front-Mu point of the Large Intestine. Front-Mu points are where the qi of the zang-fu organs converges on the chest and abdomen. As the Front-Mu point of the Large Intestine, Tianshu has a specific association with the conduction function of the large intestine in TCM theory. The Zhenjiu Jiayijing states that it primarily treats "abdominal distension and bowel sounds," making it a commonly used acupoint for understanding abnormal defecation.
Which TCM Patterns Might Be Responsible?
Frequent bowel movements with small volume each time commonly corresponds to the following TCM patterns: First, spleen deficiency with exuberant dampness — the spleen is too weak to transform and transport water-dampness, which pours down into the intestines, causing unformed stools that are difficult to expel; Second, liver qi stagnation — emotional distress affects the movement of qi, disrupting intestinal peristalsis, resulting in increased frequency of bowel movements but small volume; Third, kidney yang insufficiency — the kidney governs both urination and defecation, and when kidney yang is deficient, its warming function weakens, leaving the intestines unable to conduct properly. These patterns do not exist in isolation and may overlap with one another, requiring a licensed TCM practitioner to differentiate through the four diagnostic methods of inspection, auscultation and olfaction, inquiry, and palpation.
Guanyuan (CV4) is related to kidney yang and the functions of urination and defecation. Guanyuan, also known as Dantian, is located on the lower abdomen, on the anterior median line, 3 cun below the umbilicus. It belongs to the Ren Meridian and serves as the Front-Mu point of the Small Intestine. TCM holds that the kidney governs both urination and defecation, and Guanyuan is where original qi is stored, closely related to the warming function of kidney yang. The Nanjing mentions "the moving qi between the kidneys below the umbilicus," and this acupoint is regarded in TCM theory as an important health-preserving point of the human body.
How Can Daily Diet Be Adjusted?
If you frequently experience frequent bowel movements with small volume each time, you may wish to start with dietary adjustments for daily care. TCM emphasizes that "food and medicine share the same origin," and recommends consuming more foods that strengthen the spleen, boost qi, and resolve dampness, such as Chinese yam, coix seed, poria, and white hyacinth bean, which can be cooked into porridge or soup. At the same time, avoid raw, cold, greasy, and pungent stimulating foods, as these increase the burden on the spleen and stomach. However, note that dietary adjustment is only an auxiliary measure and cannot replace professional pattern differentiation. Licensed TCM practitioners advise that if symptoms persist, it is better to seek detailed consultation at a proper medical institution.
Is TCM Conditioning Necessary? How to Choose?
Many friends ask: for frequent bowel movements with small volume each time, can moxibustion, tuina, or Chinese herbal medicine be used for conditioning? The answer is yes, but only after a licensed TCM practitioner has performed pattern differentiation. For example, those with spleen deficiency and exuberant dampness may be suitable for moxibustion. However, these methods must be individualized and should never be self-imitated. Remember, the core of TCM conditioning is "treatment based on pattern differentiation," not "one formula for a thousand people."
Summary: How to Properly View This Problem?
Frequent bowel movements with small volume each time may seem like a minor issue, but it may reflect imbalances in the functions of the spleen, stomach, liver, kidney, and other zang-fu organs. It is neither typical diarrhea nor typical constipation and needs to be understood from a holistic perspective. The purpose of TCM science popularization is to help everyone recognize the body's signals, but it absolutely does not encourage self-diagnosis or self-conditioning and self-care. If you have similar concerns, bring your questions to a proper medical institution and consult a licensed TCM practitioner, who can help you analyze your constitution and provide pattern-based conditioning. After all, health is not achieved overnight but requires a patient process of care. Are you ready to listen to your body's voice?
