The morning after the feast, the dinner that dragged on, the meal eaten too fast and too late: the belly is hard, the breath sour, belches rise foul, and the tongue carries a thick coating. Chinese medicine has a precise name for this picture: 食积 Shí Jī, food retention. Neither deficiency nor external invasion: an overload of the table that was not transformed, and stays. It is one of the most frequent syndromes in practice, and one of the simplest to understand, provided it is not confused with Spleen deficiency.
Shi Ji: retention, neither deficiency nor invasion, an overload of the table
Shí Jī belongs to the category of Excess patterns: something is present in surplus, and that something is untransformed food. The mechanics are direct: the quantity or nature of the meal exceeds the transforming capacity of Stomach and Spleen, the food bolus stagnates in the middle burner, and everything that should descend stops or rises instead.
“When food accumulates and is not transformed, the centre is blocked: fullness, sour belching, absence of hunger.”
The distinction from other digestive pictures is clear-cut:
- Not a Spleen deficiency: deficiency gives chronic digestive fatigue, loose stools, a pale complexion; Shí Jī gives a hard belly painful on pressure, loaded breath, an acute picture after a real excess
- Not an external invasion: no chills, no aching limbs, no infectious context; the problem comes from the table, not from outside
- Not pure Qi stagnation: emotional stagnation gives bloating that fluctuates with mood; Shí Jī gives a fixed fullness tied to the last meal, with material signs (coating, breath, belching)
The signs that distinguish it from Spleen deficiency
The most frequent confusion, since both touch the Spleen-Stomach. The clinical test rests on three questions:
- Pain: Spleen deficiency gives dull discomfort that improves with pressure; Shí Jī gives a painful fullness that worsens on palpation
- Breath and belching: Spleen deficiency has neutral or faintly sour breath; Shí Jī has sour, heavy, sometimes putrid breath, and belches carrying the taste of the meal
- Tongue coating: Spleen deficiency has a thin, white, clean coating; Shí Jī has a thick, yellowish or greasy coating, testimony of untransformed matter
The modern causes: fast, rich, late meals
Shí Jī is the syndrome of contemporary lifestyle par excellence. Three dominant causes, often combined:
- Speed: eating in ten minutes, standing or in front of a screen, prevents chewing and the first work of transformation; the bolus arrives raw and whole in the Stomach
- Richness: fatty, sweet, fried meals, or simply too large, exceed the transforming capacity even of a healthy Spleen
- Timing: eating late (after 9 p.m.) or just before bed places the meal on the descent of digestive Yang, as the body prepares nocturnal Yin; the Stomach’s fire is no longer there to transform
The aggravating combinations are classic: a meal both rich and late, fast and standing, excess and emotion (the “stress meal” adding stagnation to overload). The picture then doubles: Shí Jī + Qi stagnation, material fullness plus emotional blockage.
Dissolve and restart: the mobilising foods
The strategy for Shí Jī is dissipation: helping the centre dissolve the mass and restart the descent. The mobilising foods have been known for centuries:
| Food | Action |
|---|---|
| Hawthorn (山楂 Shān Zhā) | Dissolves stagnant fats and meat; the first mobiliser of Shí Jī |
| Radish seed (莱菔子 Lái Fú Zǐ) | Descends Stomach Qi, dissolves starch retention |
| Sprouted barley (麦芽 Mài Yá) | Dissolves stagnant starches and dairy |
| Fresh ginger | Restarts digestive fire and descent |
| Lemon, vinegar | Gentle sourness that dissolves and freshens stagnation |
| Mint, coriander | Open the surface and lighten the centre |
The practice is simple: a light hawthorn or sprouted-barley broth after too rich a meal, a clear soup the next day, and above all the rule of the pause: let the Stomach empty before filling it again. Eating “on top of” a retention is the surest way to prolong it.
When retention turns into Heat or Dampness
Shí Jī is not a stable state: stagnant matter ferments, and fermentation produces Heat and Dampness. This is the natural evolution of the untreated syndrome:
- Shi Ji → Heat: the coating turns yellow, the tongue reddens, thirst appears, stools become dry or burning; the picture shifts from “overload” to “Stomach Heat”
- Shi Ji → Dampness: the coating thickens and turns greasy, the body grows heavy, stools become sticky; the picture slides towards Spleen Dampness
- Shi Ji → Damp-Heat: the most frequent combination: yellow-greasy coating, loaded breath, sticky foul stools
Frequently asked questions
What is the difference between food retention and indigestion?
Western indigestion is a symptom; Shí Jī is a syndrome: it describes the stagnant matter, its transformation into Damp-Heat, and its specific signs (thick coating, sour breath, fullness painful on pressure). The Chinese concept is more precise: it names the matter, not merely the discomfort.
Is fasting the right remedy?
Relative fasting yes, total fasting not necessarily. Tradition recommends “letting the centre breathe”: clear soup, broth, a small light meal, rather than a dry fast that weakens an already strained Spleen. The aim is to let the Stomach finish its work, not to punish it.
Why are children so prone to it?
The child’s Spleen is “constitutionally insufficient” (脾常不足): its transforming capacity is naturally limited. A rich meal, an over-generous snack, a late dinner is enough to create Shí Jī. That is why Chinese traditions insist so much on regularity, cooking and simplicity in children’s meals.
When should you consult a practitioner?
If the picture recurs (more than once a month), if it comes with fever, persistent vomiting or acute pain, or if it concerns an infant. Occasional Shí Jī is a table matter; chronic Shí Jī reveals a Spleen that can no longer transform, and deserves real treatment.
Overload dissolves; deficiency nourishes
Food retention is the syndrome of too much, and its antidote is simplicity: let the centre work, dissolve rather than add, restart the descent rather than force. For more complex digestive pictures, the protocol on digestive disorders in Chinese dietetics covers the combinations; for the reverse mechanism (Qi rising when it should descend), the article on rebellious Qi details the counterflow.
