Pediatric Poor Appetite and Growth-Period Nutrient Absorption — Korean Medicine Treatment for Spleen-Stomach Weakness
Table of Contents
Korean medicine causes of poor appetite during the growth period
When a child refuses to eat, parents become anxious. Force-feeding leads to gagging, but leaving the child alone raises worries about a small, thin frame compared with peers. Korean medicine sees the core cause of pediatric poor appetite as spleen-stomach weakness (脾胃虛弱). The spleen (脾) absorbs the refined essence (精微) of food and distributes it throughout the body, while the stomach (胃) receives food and performs initial digestion. When both are weak, appetite drops on its own, and even when the child eats, nutrients are not properly absorbed.
Samchul Geonbi-tang (蔘朮健脾湯) and Igong-san (異功散)
For poor appetite of the spleen-stomach weakness type, the representative formula is Samchul Geonbi-tang. Composed of ginseng, atractylodes, poria, Chinese yam, lotus seed, and coix, it strengthens the spleen-stomach while resolving dampness (濕). For infants and toddlers who eat very little and have abdominal distension, Igong-san (異功散) is more suitable. Built on Sagunja-tang with the addition of citrus peel, it tonifies spleen qi (脾氣) while resolving qi stagnation (氣滯).
- Gagging at the smell of food: add agastache and amomum for aromatic resolution of dampness (芳香化濕)
- Frequent abdominal pain: add white peony and licorice to soften urgency and stop pain (緩急止痛)
- Loose, frequent stools: add hawthorn, malt, and medicated leaven to digest food and strengthen the spleen (消食健脾)
Picky eating and micronutrient deficiency
Children with weak spleen-stomach often have a strong tendency to reject specific tastes or textures. As a result, zinc (Zn) and iron (Fe) can become chronically deficient. Zinc deficiency dulls taste and further reduces appetite, creating a vicious cycle, while iron deficiency leads to anemia, decreased focus, and growth delay. Appropriate supplementation may also be necessary alongside herbal treatment.
Improving the eating environment
Limit meals to 20 to 30 minutes and stop snacks at least 2 hours before mealtime. Building the habit of eating only at the table without TV or smartphone strengthens the spleen-stomach's digestive focus. Praise even small amounts of eating, and introduce new foods one spoonful at a time. Pediatric chuna (children's massage) gently circulates the abdomen and supports recovery of spleen-stomach function.
