Belly Swells Like You’re Pregnant Every Afternoon? — Check Whether It’s "Shao Fu Gu Tu"

Opening: a disease so strange it baffles everyone

Friends often ask Doctor Luo Dalun about a "strange" disease: the belly swells up every afternoon. How punctual is it? It starts swelling around three o’clock every afternoon, and reaches its worst at six or seven in the evening. After dinner, the belly is so bloated it looks like pregnancy, and you can barely eat any more. But lie down and sleep through the night, and by morning the belly seems flat again — the morning is completely normal. Then, at three or four in the afternoon, it swells right on schedule again.

💬 Note from Doctor Luo: People often ask me about this strange disease. What disease is it? Why does my belly swell up — and why does it swell at a particular time? They say it swells every afternoon, starting around three o’clock, worst at six or seven in the evening. After dinner, the belly bloats up as if about to give birth, and you basically can’t eat much.

In fact, many people have this symptom to one degree or another — some people’s bellies swell only slightly in the afternoon, not so noticeably; in severe cases, the belly becomes as large as a pregnant woman’s.

Who gets this? And why does it only bulge in the afternoon?

Doctor Luo Dalun’s analysis: in most cases this is insufficient upright qi — qi deficiency leaning toward yang deficiency (of course, an occasional case is damp-heat, but the majority are deficiency).

💬 Note from Doctor Luo: Such people often used to love cold foods — raw fruit eaten casually, lots of cold drinks. That’s the external cause: their yang qi has been injured. But first of all, what is the internal cause? The internal cause is their own insufficient upright qi — such people often lack exercise, and sometimes diet and overwork have consumed their upright qi.

External cold injuring the yang, plus internal insufficiency of upright qi — the two together produce yang qi deficiency. And when qi deficiency reaches a certain point, what happens? It is called the sinking of the qi mechanism (qi ji xia xian) — the qi mechanism sinks downward.

Doctor Zhang Xichun’s "da qi xia xian" (the great qi sinking): the qi in the chest can’t rise

When we speak of the sinking of the qi mechanism, we must first mention the doctrine founded by Doctor Zhang Xichun — da qi xia xian, the great qi sinking. Where is this "great qi"? In the chest. When the great qi sinks, what happens to a person? When they exhale, they can’t get the breath out — they feel oppressed and suffocated, with all the qi piled up below.

💬 Note from Doctor Luo: Ever since I gave these talks on Doctor Zhang Xichun, many netizens have written to me — they never knew what disease they had, went to the hospital and couldn’t be diagnosed, yet they felt miserable, had no strength, and felt their chest qi oppressed and unable to rise. In the end, comparing my lectures with their symptoms, they discovered the great qi sinking. Then they used Doctor Zhang Xichun’s Sheng Xian Tang (the Raise the Sinking Decoction), whose main ingredient is raw huang qi (astragalus), combined with a little upward-lifting medicine — and many people found that after using the formula, their symptoms disappeared immediately, and they recovered very quickly.

The reason it worked so fast is that the formula matched the pattern exactly.

Doctor Li Dongyuan’s "zhong qi xia xian" (the middle qi sinking): the root is in the spleen and stomach

A similar approach comes from Doctor Li Dongyuan, one of the four great masters of the Jin-Yuan period — the middle qi sinking (zhong qi xia xian). Where is the middle qi sinking located? In the spleen and stomach — the spleen and stomach can no longer absorb the nutrients from food, gradually weaken, and can no longer lift the qi upward, so the qi goes down instead. Doctor Li Dongyuan’s method was the Bu Zhong Yi Qi Tang (Tonify the Middle and Replenish Qi Decoction), whose main ingredients are also ren shen (ginseng) and huang qi.

💬 Note from Doctor Luo: So what is the difference between the two? Where does Doctor Li Dongyuan’s Bu Zhong Yi Qi Tang focus its care? On the spleen and stomach — with spleen deficiency as the primary problem; he also takes care of blood deficiency, which is why there is dang gui (Chinese angelica) to nourish the blood. And Doctor Zhang Xichun’s Sheng Xian Tang focuses mainly on the heart and lungs. That condition tends to be more severe — the entire great qi has sunk, so it can be quite serious. Bu Zhong Yi Qi is gentler in nature: it first regulates the spleen and stomach, then gradually lifts the qi upward.

Fundamentally, both formulas supplement the middle qi — both treat the symptoms that appear when qi deficiency causes the qi to move downward.

This bulge has a proper medical name: shao fu gu tu (bulging protrusion of the lower abdomen)

Among people with qi deficiency and sinking, abdominal bloating appears very easily; Chinese medicine calls it shao fu gu tu — the lower belly is always bulging. What are its characteristics?

💬 Note from Doctor Luo: First of all, the bulge is soft. It looks huge when swollen, but when you press it, it’s soft — as if there’s qi inside. And when you go to the hospital for a checkup, nothing has grown inside — no tumor, no fluid accumulation at all. It’s simply bulging.

Such patients also have these traits:

• The pulse is especially weak — particularly the right-hand pulse, and the right cun position (the distal position on the wrist) is even weaker;
• Long-term fatigue and a haggard look — they always seem to lack strength and energy;
• Eating anything cold makes the bulge worse immediately — one tomato, one apple, or a few slices of cold watermelon, and the belly swells right away;
• Once bloated, they cannot eat — food gets stuck inside, so their dinner portions are especially small. They themselves wonder: why do I eat so little and still feel this bloated?
• The tongue is swollen and fat, with teeth marks — the classic sign of qi deficiency.

💬 Note from Doctor Luo: This is called qi xu bu yun — qi deficiency failing to transport. Your upright qi has already become deficient to a certain degree; it can no longer transform and transport food. Anything that goes in is a heavy burden that cannot be moved along, so after eating it stays bloated for a long time — the whole night long it doesn’t dissolve. Only while you sleep does your upright qi recover a little — your body isn’t performing movements and consuming qi — and it is only with this bit of qi that the food is gradually digested away.

There is another very distinctive sensation: breathing feels oppressed — when you inhale, the belly pushes up against you, and there is no room left to take in air, so inhaling becomes especially difficult. After dinner, sitting there and simply breathing is an effort.

💬 Note from Doctor Luo: This is the view of the famous Chinese medicine master Doctor Li Ke — he held that inhalation becomes especially difficult. And what did Doctor Zhang Xichun think? He thought exhalation was difficult. Why the difference? Because the cases Doctor Zhang Xichun encountered had extremely severe great qi sinking — at that point there was no strength left even to breathe out. What we generally encounter is difficulty inhaling — the belly is too bloated, and there is no room left to hold air.

What to do? Step one: watch your mouth — no more cold foods

If this description fits you, the first thing is: absolutely stop eating cold things. You can also use moxibustion to warm the body and protect yourself. Second, take Chinese herbal medicine promptly — it will pass quickly.

💬 Note from Doctor Luo: If there is a TCM doctor nearby, ask them to write you a prescription — for example, Bu Zhong Yi Qi Tang or Sheng Xian Tang, either one will do. The famous TCM master Doctor Li Ke took this disease out and discussed it specially — the shao fu gu tu condition. He specifically combined and modified these two formulas, increased the dosage, and added a little kidney-tonifying medicine — for example, he would often add bu gu zhi (psoralea fruit), walnuts, and so on.

Why did Doctor Li Ke add kidney-tonifying herbs? Because he believed: if the qi is too deficient and you only lift it upward, you risk ti tuo — the qi being "lifted off" — the qi is suddenly pulled away, and the lower part empties out. So he would add kidney tonics (for example, red ginseng). This piece of experience is very important.

No TCM doctor nearby? — Use the patent medicine Bu Zhong Yi Qi Wan

If there is no TCM doctor nearby, Doctor Luo Dalun says it’s very simple: try the patent medicine Bu Zhong Yi Qi Wan.

💬 Note from Doctor Luo: When Doctor Li Dongyuan treated this condition back then, the Bu Zhong Yi Qi Tang he prescribed actually used fairly small doses. Now that we’ve made it into a pill, taking a little at a time can still markedly relieve the symptoms. Many friends kept taking it, and their symptoms gradually disappeared — which shows that when the upright qi is replenished and the middle qi becomes sufficient, the qi lifts upward, and this shao fu gu tu no longer appears.

In Doctor Luo Dalun’s own experience, it often helps to pair the pill with something else: take Bu Zhong Yi Qi Wan in the morning, and Jin Gui Shen Qi Wan (the Kidney Qi Pill from the Golden Cabinet) once in the evening — this is for people with kidney yang deficiency.

💬 Note from Doctor Luo: Just the other day I ran into such a case — a friend whose tongue was red, but who had every symptom of qi deficiency. Qi deficiency and yin deficiency combined — that’s called qi-yin dual deficiency. So I told him: take Bu Zhong Yi Qi Wan every morning, and Liu Wei Di Huang Wan (the Six-Ingredient Rehmannia Pill) every evening. After persisting for two weeks, the results were good. Friends, only when the treatment matches the pattern will it work.

Don’t forget: when qi deficiency is extreme, even the internal organs prolapse

From analyzing this symptom we can draw out an important principle of Chinese medicine: when qi deficiency becomes extreme, the qi moves downward — it can no longer hold things in place, and it sinks. In severe cases, the internal organs prolapse along with it — which is why some people develop gastric ptosis, uterine prolapse, and rectal prolapse. At that point you must supplement the upright qi, build it up fully, and at the same time prevent cold from injuring the body again. This is very important.

💬 Note from Doctor Luo: Are there other causes of this shao fu gu tu? Yes, there are — for example, qi stagnation from constrained liver qi (gan qi bu shu), and also damp-heat pouring downward (shi re xia zhu). What we discussed earlier was the deficiency pattern; the latter two are excess patterns. You need a nearby doctor to help you tell which type it is. Most of what we see is the deficiency pattern described above.

Modern people with insufficient upright qi are extremely numerous, so everyone should understand this condition — it means the middle qi has been injured and the yang qi has been injured. Don’t drink cold water, don’t drink iced beverages, eat fewer cold foods — and at the same time build up your upright qi bit by bit. When your upright qi is sufficient, the qi will no longer sink downward. This disease may seem strange, but you’ll find that many people have it to one degree or another. The earlier you understand it and the earlier you regulate it, the sooner you can protect your body.

What to take away

1. A belly that swells every afternoon, worst in the evening, and flat by morning is often "shao fu gu tu" — the bulging lower abdomen of qi deficiency with sinking.
2. The root cause is usually qi deficiency leaning to yang deficiency: the internal cause is insufficient upright qi (lack of exercise, diet and overwork); the external cause is a history of cold foods and cold drinks injuring the yang.
3. The two classical approaches are the same lineage: Doctor Zhang Xichun’s da qi xia xian (great qi sinking, in the chest, treated with Sheng Xian Tang) and Doctor Li Dongyuan’s zhong qi xia xian (middle qi sinking, in the spleen and stomach, treated with Bu Zhong Yi Qi Tang).
4. Self-check signs: the bulge is soft; hospital tests find nothing; the pulse is weak (especially the right cun); chronic fatigue and a haggard look; cold food makes it worse immediately; no appetite once bloated; inhaling is difficult; the tongue is fat with teeth marks.
5. First steps: stop eating cold foods, warm yourself with moxibustion, and take herbal medicine — Bu Zhong Yi Qi Tang or Sheng Xian Tang.
6. If no doctor is nearby: take the patent medicine Bu Zhong Yi Qi Wan; Doctor Luo Dalun’s pairing is Bu Zhong Yi Qi Wan in the morning with Jin Gui Shen Qi Wan at night (kidney yang deficiency), or Liu Wei Di Huang Wan at night for qi-yin dual deficiency — about two weeks to see results.
7. Doctor Li Ke’s warning: when the qi is extremely deficient, lifting it too hard risks "ti tuo" (the qi being lifted off), so kidney-tonifying herbs such as bu gu zhi, walnuts, and red ginseng are added.
8. If left unchecked, extreme qi deficiency can lead to prolapse — gastric ptosis, uterine prolapse, or rectal prolapse. Build up your upright qi and protect yourself from cold.
