Child Always Hungry, Eating Constantly but Not Gaining Weight? Doctor Luo Dalun: Stomach Strong, Spleen Weak — Clear the Food Stagnation First, Then Nourish the Spleen-Yin

Opening: looking at tongue photos has become a signature segment of this program

For several days in a row, Doctor Luo has been helping parents read photographs of their children’s tongues. One tongue after another comes in — in every shape and condition — and parents are often worried: what on earth is going on with my child’s tongue?

💬 Note from Doctor Luo: I think this has become a signature segment of our program. Everyone sends the photos in, I take a look, and the parents listen along — the more you hear, the more you know, until no matter what strange change appears on your child’s tongue, you understand what it means. In this way, you can really protect your own children.

Today’s question is this: this child always wants to eat, and seems never to get full. What is going on?

Always hungry, never full: this is not a good appetite — it’s heat in the stomach

Many parents hear “my child can eat” and feel happy, thinking the appetite is good. Doctor Luo, however, reminds us: a child who is always stuffing things into their mouth and always complaining of hunger is often not a good sign.

💬 Note from Doctor Luo: This often means there is heat in the stomach — stomach heat (wei re). Some children with stomach heat also have spleen deficiency; we call it stomach heat with spleen deficiency. When the stomach is hot, the fire is strong, so the child always wants to take things in — in Chinese medicine we call this xiao gu shan ji (voracious appetite from stomach heat), always wanting to eat things.

But this one signal alone is not enough — you have to read it together with the other symptoms.

Bad breath, red eye bags, four days without a bowel movement: the signals line up one after another

This child also shows several other signs: bad breath, red-purple lower eye bags, no bowel movement for four days, a reluctance to drink water, and a short temper.

💬 Note from Doctor Luo: What could bad breath mean? Food stagnation (ji shi), right? Then you might say — doesn’t food stagnation make a child not want to eat? Yes, when the spleen and stomach are blocked, at first the child really does not want to eat. But if the stomach’s function has been injured and develops toward heat, the child becomes hungry again — yet no matter how much they eat, the nutrition is not absorbed, so the child still cannot gain weight. This is what it looks like when the spleen and stomach have been injured.

And what do the red-purple lower eye bags tell us?

💬 Note from Doctor Luo: They tell us the child’s spleen has been injured — very likely spleen-yin deficiency (pi yin bu zu). Add the four days without a bowel movement, the reluctance to drink water, and the short temper — putting it all together, this child is very likely what we in Chinese medicine call “stomach strong, spleen weak” (wei qiang pi ruo).

Look at the tongue: thick coating in the middle is food stagnation, small red bumps are heat

After asking about the symptoms, look at the tongue. This child’s tongue comes out: the coating in the middle is thick, and there are many small red bumps on the surface, clearly standing up.

💬 Note from Doctor Luo: A thick coating in the middle of the tongue means food stagnation — there is accumulated food. The small red bumps on the tongue tell us the constitution has heat — there is heat inside the body. But right now, because the qi and blood are insufficient, the bumps are not bright red — if the qi and blood were sufficient, these red spots would be bright red.

Stomach strong, spleen weak: the stomach is like a greedy monster, while the spleen absorbs nothing

String the signals together, and the four characters “stomach strong, spleen weak” rise to the surface. What does this phrase actually mean?

💬 Note from Doctor Luo: It means that after the spleen and stomach have been injured, the stomach develops toward heat and appears very strong — so it especially loves taking things in, and you always feel hungry. The spleen, meanwhile, does not absorb — it does not absorb. The spleen’s yin has also been injured. Very likely this child started with food stagnation, and one thing led to another until all these problems appeared.

The treatment plan in three steps: first clear the food stagnation, then nourish the spleen-yin

The direction is clear — now how do we adjust it? Doctor Luo gives the steps plainly.

💬 Note from Doctor Luo: First of all, what do we do? Clear the food stagnation — the accumulated food has to be dissolved. If the food stagnation is not cleared, the qi movement stays blocked, and nothing else can recover. After the stagnation is cleared, what next? Next, strengthen the spleen — and especially nourish the spleen-yin.

What do we use to nourish the spleen-yin?

💬 Note from Doctor Luo: To nourish the spleen-yin, we use sheng di (Rehmannia), sha shen (Adenophora) and mai dong (Ophiopogon) — these nourish yin — paired with a little shan yao (Chinese yam), yi mi (coix seed), qian shi (euryale seed) and lian zi rou (lotus seed) — these strengthen the spleen. So we are nourishing yin and strengthening the spleen at the same time. Children like this should also eat less meat — children who eat a lot of meat are often spleen-yin deficient.

What to do about the constipation? Almond drink opens the lung qi — it works within a minute

Four days without a bowel movement is what worries the parents most. Doctor Luo says that when the spleen is weak, the bowels may not move — but spleen weakness develops in two directions:

💬 Note from Doctor Luo: Spleen weakness develops in two directions. One is diarrhea — the spleen can no longer hold things in. The other is dryness. If the spleen-yin is deficient, it tends to move toward dryness. What to do then? On the one hand, nourish yin; on the other hand, give the child some whole grains — for example, beat some corn into a paste and feed it to them; corn helps digestion. Also give red date flesh — red date flesh moistens the intestines. And you can give almond drink — almonds can open the lung qi. The lung and the large intestine are interior-exterior paired (fei yu da chang xiang biao li), so once the lung qi opens, the large intestine opens too. That’s why this kind of thing often happens: a child is constipated, cannot go no matter what, you give them half a bottle of almond drink, and the bowels move freely — I even think the very smell of the almonds does something.

With that, Doctor Luo tells a story from his own family:

💬 Note from Doctor Luo: Once, my younger sister told me her child had not had a bowel movement for two or three days and asked what to do. I said, drink some almond drink. The moment the almond drink went down — I don’t think even a minute passed — the child immediately said, “I need the potty, I need to go to the bathroom” — and went right away. What was that? The medicinal qi went down, opened the lung qi, and the effect was remarkably fast.

A bonus tuina method: push the side of the index finger, gently, about 200 times

Besides eating, there is also a medicine-free method — pediatric tuina (massage). Doctor Luo teaches the parents on the spot:

💬 Note from Doctor Luo: Push the index finger of the child’s hand — lay the hand flat with the palm facing down, and look at the side near the thumb. Push from the wrist toward the fingertip — you can push from the base of the finger to the tip — gently, no need for much force, usually about 200 pushes. Once the bowels move, stop pushing. If you combine it with almond drink, I believe it will clear quickly.

Don’t forget the root: spleen-yin deficiency — and feeding is the key

Getting the bowels to move is easy, but Doctor Luo reminds the parents: don’t think it’s over once the bowels move.

💬 Note from Doctor Luo: Although getting them to move is easy, the root cause is spleen-yin deficiency. So always remember: first clear the food stagnation, and at the same time nourish the spleen-yin and strengthen the spleen — then the bowel movement will slowly return to normal. These are the steps this child needs to adjust.

Finally, Doctor Luo strings today’s takeaways together once more: first, we explained food stagnation again — most children’s illnesses are related to food stagnation; second, almond drink opens the lung qi and unblocks the qi of the large intestine — adults can use this method too; third, push the side of the index finger, from the base of the finger toward the fingertip, gently, about 200 times, to relieve constipation.

💬 Note from Doctor Luo: Later, I’ll tell you more about the features of children’s tongues. A child’s tongue is the most honest instruction manual of the body.

What to take away

Always hungry and never full = heat in the stomach (often stomach heat with spleen deficiency) — Chinese medicine calls it xiao gu shan ji (voracious appetite from stomach heat). It is not a sign of a “good appetite.”
Bad breath = food stagnation. At first food stagnation makes a child refuse food; once the stomach injury develops toward heat, the child becomes hungry again — but cannot absorb the food and cannot gain weight.
Red-purple lower eye bags = the spleen has been injured — spleen-yin deficiency. Combined with four days without a bowel movement, reluctance to drink water, and a short temper, the picture is “stomach strong, spleen weak” (wei qiang pi ruo).
Tongue reading: thick coating in the center = food stagnation; small red bumps standing up on the tongue = heat inside (duller red when qi and blood are insufficient, bright red when they are sufficient).
Treatment order: clear the food stagnation first (blocked qi movement blocks everything else), then strengthen the spleen — especially nourish the spleen-yin: sheng di, sha shen and mai dong to nourish yin, plus shan yao, yi mi, qian shi and lian zi rou to strengthen the spleen.
Eat less meat — children who eat a lot of meat are often spleen-yin deficient.
Spleen weakness runs in two directions: diarrhea or dryness. For dryness, give corn paste (aids digestion), red date flesh (moistens the intestines), and almond drink — almonds open the lung qi, and the lung is interior-exterior paired with the large intestine, so the bowels open fast (Doctor Luo’s sister’s child went within a minute of drinking it).
Pediatric tuina for constipation: push the side of the index finger (palm facing down, near the thumb), from the base toward the fingertip, gently, about 200 times — stop once the bowels move.
The root is spleen-yin deficiency: clear the food stagnation while nourishing the spleen-yin and strengthening the spleen — the bowel movement then returns to normal on its own.
