"No appetite; one bite and I’m full." "Unbearable bloating after meals, constant belching." "Food sits undigested; sticky loose stools." These are the signatures of Spleen-Stomach dysfunction in TCM — and they are far more common than most people realise. Western medicine attributes functional dyspepsia largely to poor gastric motility and gut dysbiosis. TCM’s framework is broader: the root lies in impaired Spleen-Stomach transformation and transportation, combined with disrupted Qi flow. Treating it requires not just symptomatic relief but restoring the Middle Jiao’s functional capacity. This guide covers five patterns, four causes, universal daily care, and clear red flags for when food therapy is not enough.

I. TCM Framework: Why Appetite Disappears

In TCM, poor appetite (na dai) and indigestion (pi man, ji zhi) are attributed to Spleen-Stomach functional failure. The Spleen transforms food into nutritive essence and transports it to all organs; the Stomach receives and descends. When either fails, two distinct problems emerge: Spleen-Stomach Qi deficiency (the engine has insufficient power) and Qi stagnation (the engine is blocked). Functional dyspepsia — accounting for 50–70% of all indigestion cases in Western medicine — is precisely where TCM adjustment has its greatest clinical advantage.

Symptom inventory — recognise the full picture:

• Stomach: postprandial distension; frequent belching; epigastric stuffiness or dull pain; acid reflux or nausea; symptoms ease temporarily after belching or flatus
• Diet-related: reduced appetite; aversion to oily or sweet foods; early satiety; worsening bloating after forced eating
• Stool: sticky unformed stools; alternatively, dry difficult stool; undigested food in stool (classic Spleen-Stomach insufficiency)
• Systemic: mental fatigue and heavy limbs; sallow complexion; weight loss; poor immunity; frequent colds

Symptoms recurring over more than 1 month indicate significant Spleen-Stomach impairment requiring systematic care.

II. Four Root Causes

1. Dietary irregularity — the primary culprit
Overeating, irregular meal timing, prolonged consumption of oily, raw, cold, spicy, or sweet-sticky foods overburdens and damages Spleen-Stomach function. Eating too much causes food stagnation; eating too little deprives the Spleen of its nutritive base. Takeaways, cold drinks, and erratic meal schedules disrupt the Spleen’s rhythmic transformation cycle. Gas-producing foods (legumes, sweet potato) in excess also worsen bloating.

2. Emotional dysregulation (Liver Qi invading Spleen-Stomach)
Long-term anxiety, anger, or chronic stress causes Liver Qi stagnation, which horizontally invades and disrupts Spleen-Stomach Qi flow. The classic observation: appetite disappears and bloating worsens with emotional upset; eating becomes easier when emotionally settled. Emotional causation is harder to treat than dietary causation and more prone to relapse.

3. Constitutional Spleen-Stomach weakness
Congenital weakness, chronic illness, overwork, or ageing depletes Spleen-Stomach Qi. The conveyor belt has insufficient drive regardless of what is put into it. These patients tolerate almost no cold or oily food; their symptoms are mild but chronic and extremely prone to relapse.

4. Sleep deprivation and overwork
"Lying down, Blood returns to the Liver" — sleep is the time when Spleen-Stomach Qi is regenerated. Chronic late nights and irregular schedules deplete Qi-Blood, slow gastric motility, and progressively impair Spleen-Stomach transformation. This is the most common single cause in office workers and shift workers.

III. Five Patterns and Targeted Treatment

Pattern 1: Spleen Deficiency with Qi Stagnation — most common; chronic fatigue with bloating
Signs: poor appetite; early satiety; postprandial bloating with frequent belching (relieved by flatus); fatigue; sallow complexion; loose or sticky stools; pale tongue with thin white coating; thin wiry pulse.
Strategy: strengthen Spleen, harmonise Stomach, move Qi and relieve bloating.
Formula: Xiang Sha Liu Jun Zi Tang modified — Dang Shen, Bai Zhu, Fu Ling strengthen Spleen Qi; Mu Xiang, Sha Ren move Qi and descend Stomach counterflow; Chen Pi, Ban Xia harmonise and dry Damp; Zhi Gan Cao harmonises. Patent: Xiang Sha Liu Jun Wan, Zhi Zhu Kuan Zhong Capsules.
Diet: Sha Ren congee — cook rice 100g to congee; add ground Sha Ren 5g in the final 10 min. Twice daily. Warms and harmonises Spleen, moves stagnant Qi. Also: yam-millet congee for sustained daily use.
Lifestyle: Regular meals; 70–80% fullness per meal; slow walk 15–20 min after eating; consistent sleep before 11pm.

Pattern 2: Liver-Stomach Disharmony — emotion-triggered; flanks and stomach affected together
Signs: poor appetite; epigastric distension radiating to both flanks; symptoms reliably triggered or worsened by emotional upset; frequent sighing; bitter dry mouth; irritability; constipated; pale-red tongue with thin white coating; wiry pulse.
Strategy: soothe Liver Qi, harmonise Stomach, descend counterflow.
Formula: Chai Hu Shu Gan San modified — Chai Hu, Zhi Ke, Xiang Fu soothe Liver and move Qi; Chuan Xiong, Bai Shao activate Blood and relieve pain; Chen Pi, Zhi Gan Cao harmonise Stomach. Add Fo Shou, Chen Pi for pronounced bloating. Patent: Qi Zhi Wei Tong Granules, Wei Su Granules.
Diet: chen pi-rose-fo shou tea (3–5g each, steeped); fo shou congee (Fo Shou 20g decocted, cook 100g rice in the liquid, add rock sugar). Emotional regulation is the primary treatment for this pattern — 15–20 min daily genuine relaxation (music, Tai Chi, walking).

Pattern 3: Food Stagnation — overeating-triggered; sour-rotten belching
Signs: poor appetite; epigastric stuffiness and distension with tenderness on pressure; frequent belching with sour-rotten odour; nausea; vomiting of undigested food (relieved after vomiting); sticky sour-smelling stool; history of overeating; red tongue tip with thick greasy coating; slippery pulse.
Strategy: disperse food stagnation, harmonise Middle, open appetite.
Formula: Bao He Wan modified — Shen Qu, Shan Zha, Lai Fu Zi disperse stagnation; Fu Ling, Ban Xia, Chen Pi harmonise and dry; Lian Qiao clears stagnation-Heat. For children: Xiao Er Jian Pi Hua Ji oral liquid.
Diet: white radish soup (disperses stagnation, descends Qi); small amounts of Shan Zha water (6g simmered 10 min). Temporary shift to liquid or semi-liquid diet (congee, soft noodles); reduce meal size strictly.
Lifestyle: clockwise abdominal massage to move stagnated food; gentle walking after meals.

Pattern 4: Spleen-Stomach Cold Deficiency — cold aversion; loose stools worsen with cold food
Signs: poor appetite; dull epigastric pain relieved by warmth and pressure; clear watery vomiting; cold limbs; fatigue; pallor; loose stools or early-morning diarrhoea; pale tongue with white coating; thin weak pulse.
Strategy: warm Middle, scatter Cold, strengthen Spleen, harmonise Stomach.
Formula: Huang Qi Jian Zhong Tang or Li Zhong Tang modified — Huang Qi, Dang Shen, Bai Zhu strengthen Spleen Qi; Gan Jiang, Gui Zhi warm Middle and scatter Cold; Bai Shao, Zhi Gan Cao relieve cramping. Patents: Fu Zi Li Zhong Wan, Bu Zhong Yi Qi oral liquid.
Diet: lamb congee (lamb 250g simmered, add rice 100g, cook to congee; twice daily — warms Middle and stops pain); ginger-brown sugar water. Abdominal warmth maintenance is essential; avoid all cold-raw food without exception.

Pattern 5: Spleen-Stomach Damp-Heat — sticky bitter mouth; thick greasy tongue coating
Signs: poor appetite; epigastric stuffiness and distension; bitter sticky mouth; dry mouth without desire to drink; nausea; acid reflux; scanty dark urine; sticky stool with persistent tenesmus; red tongue with thick yellow greasy coating; slippery rapid pulse.
Strategy: clear Heat, dissolve Damp, harmonise Stomach and move Qi.
Formula: Lian Po Yin modified — Huang Lian, Hou Po clear Heat and dry Damp; Shi Chang Pu, Ban Xia harmonise Stomach and dissolve Damp; Zhi Zi, Lu Gen clear Heat and generate fluids.
Diet: Yi Yi Ren-Chi Xiao Dou soup; winter melon; bitter melon; celery; mung bean. Avoid all spicy, oily, warming foods and alcohol. Light millet congee and winter melon soup as staples.

IV. Universal Daily Care: Spleen-Stomach Protection for All Patterns

Dietary “3 dos, 3 don’ts”:
Dos: light and easily digestible foods (millet, rice, yam, pumpkin, lotus seed, lean protein); small frequent meals at 70–80% fullness; regular meal timing to establish a consistent Spleen-Stomach rhythm.
Don’ts: spicy and oily foods (chilli, fried foods, fatty meat, chocolate); cold and raw foods (ice drinks, raw fish, cold salads); alcohol, strong coffee and tea; gas-producing foods in excess (legumes, sweet potato).

Three lifestyle corrections:
Do not lie down immediately after eating — stand or walk slowly 15–20 min. Do not stay up past 11pm — sleep deprivation is the single most consistent Spleen-Stomach damaging habit. Avoid prolonged sitting — every hour, stand and walk 5 min; daily 30-min exercise (walking, Tai Chi, Ba Duan Jin) promotes Stomach Qi movement.

Four acupoints for daily self-care:

• Zhong Wan (CV12): 4 cun above navel; clockwise palm massage 5–10 min; harmonises Stomach, disperses food, relieves bloating
• Zu San Li (ST36): 3 cun below outer knee; thumb pressure 1–2 min (aching sensation); the primary Spleen-strengthening point; improves Qi generation capacity
• Nei Guan (PC6): 2 cun above inner wrist crease; thumb pressure 1 min; relieves nausea, bloating, poor appetite by harmonising Stomach Qi
• Tai Bai (SP3): inner edge of foot below 1st metatarsal; thumb pressure 1 min; strengthens Spleen and Stomach, moves food stagnation, relieves loose stools

Also: regular clockwise abdominal massage around the navel 5–10 min promotes gastric motility. For Spleen-Stomach Cold deficiency: warm moxibustion at Zhong Wan and Zu San Li, 10–15 min per point, every 1–2 days.

V. When to Seek Medical Evaluation

TCM care is appropriate for functional dyspepsia. Seek urgent medical evaluation — including gastroscopy, H. pylori testing, and abdominal ultrasound — if any of the following apply:

• Persistent poor appetite and indigestion for more than 3 months, progressively worsening despite conservative adjustment
• Severe epigastric pain, vomiting blood, black tarry stool; weight loss greater than 5kg in 1 month
• Marked anaemia, pallor, dizziness, palpitations; or jaundice and abdominal mass
• Age over 40 with first occurrence of these symptoms plus any of the above alarm features

Most patients with functional dyspepsia who commit to consistent pattern-matched TCM care — including dietary correction, sleep regularity, and appropriate formula or acupoint treatment — experience meaningful improvement within 1–3 months. The two most commonly neglected factors: fixing sleep timing (before 11pm) and addressing the emotional cause where Liver-Stomach disharmony is present. Get these right first; food and herbs follow.
