Headache with Nausea and Vomiting: Who Exactly Is "Throwing a Tantrum"?

Water boils in the kitchen, the kettle lid rattling "puff-puff" under the steam, while a bowl of congee gone cold sits nearby. This scene is remarkably like a signal from the body—the "pressure" in the head and the "churning" in the stomach raising the alarm simultaneously. When Traditional Chinese Medicine (TCM) approaches such symptoms, it does not rush to suppress the pain, but rather asks a counter-question: Why is it that the head and the stomach "sound off" together?

If we liken the body's qi mechanism to urban traffic, the head is the central roundabout, and the spleen and stomach are the logistics hub. If the roundabout is blocked, traffic backs up into the hub; if the hub is paralyzed, the roundabout cannot function smoothly either. Headache with nausea and vomiting is precisely a chain reaction of these two systems alarming simultaneously. The underlying pathology here is far more complex than simply "a cold."

I. "Blockage" vs. "Malnourishment": Two Directions, Worlds Apart

A common misconception is that headache plus nausea must mean "excessive fire," and drinking some cooling herbal tea will do the trick. Rising fire can indeed cause distending headache, nausea, and a desire to vomit. But attributing all such symptoms to "excessive fire" ignores the other half of patients—those with a pale complexion, aversion to cold, dull headache, and vomiting of clear fluid. Their problem is precisely not "too much fire" but "too little fire."

In TCM clinical practice, headache with nausea and vomiting must first be differentiated as excess or deficiency. Excess patterns are mostly "pain due to blockage"; deficiency patterns are mostly "pain due to malnourishment." If the headache is severe, distending as if splitting, and the patient feels relieved after vomiting, this is mostly qi stagnation and turbid pathogens invading upward—a "blockage" pattern. If the headache is dull and persistent, worsens after exertion, and the patient feels even more exhausted after vomiting, this is mostly qi-blood insufficiency and failure of lucid yang to ascend—a "malnourishment" pattern.

"Therefore, wind is the origin of all diseases. When one is calm and tranquil, the flesh and interstices are closed and resistant, so even violent wind or severe toxins cannot cause harm."

Huangdi Neijing · Suwen · Treatise on the Communication of Vital Qi with Heaven (Chapter 3)

Although this passage speaks of external pathogens causing disease, it reveals a foundational logic: when the body's vital qi is sufficient and the pathways are unobstructed, neither external pathogens nor internal turbidity can easily cause disorder. Conversely, if the clear orifices of the head are clouded by turbid pathogens—whether wind, cold, phlegm, blood stasis, or qi stagnation—"blockage" results; if qi, blood, and body fluids are insufficient to nourish the clear orifices, "malnourishment" results. These two pathways run in opposite directions, and the treatment approaches naturally differ—one requires "dredging," the other "replenishing."

If during a headache it feels as though the head is being squeezed by a rope, with chest tightness and nausea, and there is some relief after vomiting, it may be "qi stagnation with phlegm." But if the headache is empty in nature, triggered by fatigue, with vomiting of thin, odorless fluid, it leans more toward "qi-blood deficiency with failure of lucid yang to ascend." The difference between the two is like comparing a congested river channel to a dried-up stream—"blockage" needs dredging, "dryness" needs nourishing. The disease location lies one in the "qi aspect" and one in the "blood aspect."

II. One Viscera, One Bowel: Why Do They "Join Forces" in Disease

Another common misconception: treat the head for headache, nourish the stomach for nausea and vomiting—just handle them separately, right? This is precisely where Chinese and Western medical thinking diverge. Clinical observation in TCM shows that when headache and vomiting appear simultaneously, they often point to dysfunction in the same pair of viscera and bowels—the Liver and Stomach (or Spleen).

This is because the Liver and Gallbladder channels course along both sides of the head (near the temples), and the Liver governs free coursing and regulates the qi mechanism. If emotional frustration or lingering stress causes liver qi to stagnate, the stagnation transforms into fire, and fire flares upward, charging straight to the vertex—manifesting as headache and dizziness. Simultaneously, the Liver (Wood) transversely invades and restrains the Spleen (Earth), causing stomach qi to fail in descending and instead rebel upward as vomiting. This explains why many people experience sudden migraine-like headaches with nausea after stress, anger, or staying up late—the root cause lies in the Liver, while the manifestation appears in the Stomach.

"The Liver channel of Foot-Jueyin originates from the hairy margin of the great toe... ascends through the diaphragm, spreads over the hypochondria, follows the posterior aspect of the throat, ascends to enter the nasopharynx, connects with the eye system, ascends to emerge at the forehead, and meets the Governing Vessel at the vertex."

LingShu · Channels (Chapter 10)

The Liver channel's pathway directly "ascends to emerge at the forehead and meets at the vertex"—reaching straight to the top of the head. Once this channel is obstructed by stagnant heat or cold pathogens, headache follows as a natural consequence. The relationship between the Liver and Stomach is described in Five Phases theory as "Wood and Earth overcoming each other." When liver qi stirs up trouble, the stomach goes on "strike" in sympathy—this is the origin of nausea and vomiting. Therefore, clinically, when headache is accompanied by nausea and vomiting, if there is also a bitter taste in the mouth, dry throat, irritability, and vomiting of sour or bitter fluid, the pattern differentiation is mostly approached as "Liver qi invading the Stomach."

However, it is equally important to note that "Liver" problems are not necessarily all excess fire. If liver blood is insufficient and yin deficiency with yang hyperactivity occurs, there may also be headache with dry eyes, nausea, and retching—but the tongue appears red with scanty coating and the pulse is wiry and thin. The treatment approach would then be to "soften the Liver and nourish blood" rather than "clear the Liver and drain fire." Using an "if...then it may be...but it could also be..." deduction: if the pain is in both temples and accompanied by a bitter taste, then it may be liver-gallbladder stagnant heat; but it could also be liver blood insufficiency with deficient yang disturbing upward. The former requires regulated coursing and draining; the latter requires moistening and nourishing.

III. Constitution Is the Soil, Triggers Are the Seeds

A third misconception is disregarding individual constitutional differences and focusing only on the two symptoms of "headache" and "vomiting" to find a universal answer. In clinical reality, headache with nausea and vomiting is most commonly seen in two types of constitutions: one is the phlegm-dampness constitution, characterized by a diet of rich, fatty, and sweet foods, a heavy and lethargic body, and sticky throat phlegm; the other is the qi-stagnation constitution, characterized by high stress, excessive worrying, and shallow sleep. With identical symptoms, the underlying "soil" is completely different, and health maintenance approaches naturally cannot be treated with a "one-size-fits-all" solution.

When a person with phlegm-dampness constitution has an attack, they often feel their head is heavy as if wrapped—like wearing a wet cap—with a strong sense of nausea, and the vomitus consists mostly of phlegm-drool and white foam. This aligns with the theory that "without phlegm, there is no dizziness."

"Without phlegm, there is no vertigo; the root of phlegm is water, which originates from the Kidneys."

Jingyue Quanshu · Miscellaneous Syndromes

Although Zhang Jingyue was discussing "vertigo," the pathophysiology is shared with headache accompanied by nausea and vomiting. When the spleen and stomach lose their transportation and transformation function, water-dampness accumulates and forms phlegm. Turbid phlegm clouds the clear orifices above, causing headache and dulled consciousness, while phlegm obstructs the middle burner, causing stomach qi to rebel upward as vomiting. For such individuals, daily life should avoid raw, cold, sticky, and greasy foods. The spleen and stomach prefer warmth and dislike cold—a cup of warm water surpasses countless "fire-lowering" remedies.

For those with qi-stagnation constitution, attacks are typically preceded by emotional fluctuations or sleep deprivation. When the qi mechanism is not free-flowing, stagnation transforms into fire, or stirs liver yang to hyperactive upward. This type of headache is often accompanied by irritability, distending pain in the chest and hypochondria, and frequent but small-volume vomiting. Using an "if...then..." deduction: if the headache intensifies or eases with emotional changes, then it may be qi stagnation transforming into fire; but it could also be qi stagnation leading to blood stasis with stasis obstructing the collaterals—the latter presents with fixed, needle-like pain and a dark purple tongue, which cannot be resolved by simply coursing the Liver.

In daily life, dietary recommendations do indeed differ. Those with phlegm-dampness constitution should eat light, dampness-draining foods such as winter melon or congee made with coix seed (Job's tears), but care should be taken not to deliberately pursue "removing dampness"—simply reducing the burden on the spleen and stomach is sufficient. Those with qi-stagnation constitution may appropriately consume qi-moving and depression-relieving items such as aged tangerine peel brewed in water or jasmine tea. Regarding daily routines, both types should avoid staying up late—the nighttime hours are when the Liver and Gallbladder channels are in command. Staying up late is equivalent to "adding fuel to fire" or "pouring water onto dampness."

In terms of emotional regulation, the qi-stagnation constitution is the most challenging. When everything weighs on the mind, how can liver qi unfold? In TCM, "coursing the Liver" is far more than a single herb—it is a life attitude. Try taking a deep breath when headache makes you want to vomit, feeling the breath sink downward rather than being trapped in the chest—this in itself is a form of "descending rebellion." As for exercise and daoyin guidance, the Eight Sections of Brocade (Baduanjin) movement "Regulating the Spleen and Stomach by Lifting Single Arm" is quite helpful for improving the ascending and descending of the qi mechanism. However, the specific frequency and range of practice should be determined by a licensed TCM practitioner based on individual constitution—do not blindly imitate or pursue prolonged practice.

The Distinction Between Constitution and Pattern

- Phlegm-dampness Obstructing the Middle Pattern: Main manifestations—headache with clouded sensation, heavy as if wrapped; accompanying symptoms—oppression in the chest and epigastrium, vomiting of phlegm-drool, poor appetite; tongue and pulse features—white greasy tongue coating, slippery or soggy pulse; pathomechanism—loss of spleen transportation, dampness accumulating into phlegm, turbid phlegm clouding the clear orifices.

- Liver Yang Hyperactivity Pattern: Main manifestations—distending headache, dizziness; accompanying symptoms—irritability and easy anger, bitter taste and dry throat, vomiting with acid regurgitation, restless sleep; tongue and pulse features—red tongue with thin yellow coating, wiry and forceful pulse; pathomechanism—liver qi stagnation transforming into fire, yang hyperactivity disturbing upward, stomach qi rebelling upward in tandem.

- Qi-Blood Deficiency Pattern: Main manifestations—dull persistent headache that lingers on; accompanying symptoms—triggered by exertion, spiritual exhaustion and fatigue, vomiting of clear saliva, lusterless complexion; tongue and pulse features—pale tongue with white coating, thin and weak pulse; pathomechanism—insufficient qi and blood, failure of lucid yang to ascend, brain deprived of nourishment, stomach failing to harmonize descent.

From Treating Disease to Seeing the Person

Let us return to that pot of boiling water. Some people rush to turn off the flame, others rush to lift the lid to let out steam, still others add firewood to the stove... But the truly sound approach is to first figure out: why did this pot of water boil? Is the fire too strong? Is the water too little? Or is the spout blocked?

Headache with nausea and vomiting is, ultimately, the body's "pressure relief valve" sounding the alarm. It reminds us that the qi mechanism is blocked, the blood is insufficient, or turbid phlegm has accumulated too much. Any single explanation risks being one-sided.

"Those who grasp the essential can grasp it in one sentence; those who do not grasp the essential will be scattered into endless complexity."

Suwen · Treatise on the Ultimate Principles of Medicine

The "essential" in TCM lies not in the disease name, but in the pathomechanism. Next time you encounter a headache, try to feel it: Is the pain at the forehead or both temples? Is it distending, stabbing, or empty in nature? Do you feel lighter or more exhausted after vomiting? These details are precisely the "pattern differentiation memo" your body gives you. Have you ever considered that headache might not just be a problem of the head? It could be your body reminding you—that some things need to be let go; some qi needs to be smoothed out; some rhythms need to slow down.
