When to worry
Most irritability is life rather than illness. The presentations below are the exceptions, and two of them are emergencies. Read this list before the rest — particularly the first item, which is the one people are least likely to act on.
Get help now — same day or emergency
- Thoughts of harming yourself or someone else, or a sense that you might lose control. This is a medical emergency — contact emergency services or a crisis line now.
- Irritability with very little sleep, racing thoughts, grandiosity and unusual energy. This can be a manic episode and needs urgent assessment.
- A sudden change in personality or behaviour, especially with confusion, headache, or after a head injury.
- Irritability with a racing heart, fever, sweating and confusion — this combination needs urgent assessment.
- Aggression with alcohol or drug withdrawal.
Get it looked at within days
- Irritability with weight loss, tremor, heat intolerance and a fast pulse — thyroid function.
- Irritability with low mood, loss of interest and disturbed sleep for more than two weeks.
- Irritability that began with a new medicine, or with a change in dose. Steroids, some antidepressants and stimulants are common causes.
- Irritability around the menstrual cycle that is severe enough to affect work or relationships.
- Irritability with memory change or with a personality change noticed by others rather than by you.
The rest of the page assumes none of the above. One thing worth saying plainly: irritability that others notice before you do, and that has changed over months, is worth taking seriously even when it feels like a reaction to circumstances.
One rule for this whole list: if you are not sure whether a line applies to you, treat it as though it does — and get it checked. Uncertainty is a reason to be seen, not a reason to wait.
Four kinds of irritability
The tradition separates these by what the anger does — whether it is held and distending, or released and rising — and by what accompanies it. The third and fourth categories are the ones ordinary medicine cares most about.
Held in, with tightness and sighing
Irritability that is suppressed rather than expressed, with a sense of pressure in the chest or flanks, sighing, and a tendency to feel better after crying or after a long exhale.
Points to Liver qi constraint. The most common presentation, the most reversible, and the one most responsive to changes in load and breathing.
Rising, with headache and a red face
Sudden intense anger, with a throbbing headache, red eyes or face, a bitter taste, and sometimes ringing in the ears.
Points to Liver fire. Blood pressure should be checked, particularly if the headaches are new or if this is happening over 50.
Restless, with heat and poor sleep
Irritability that is closer to being unable to settle — with night sweats, palpitations, a dry mouth, and sleep that breaks.
Points to Yin deficiency with empty heat. This is the presentation that gets worse with warming tonics, which is a common self-treatment error.
Flat, then explosive
Long stretches of low mood or numbness, punctuated by disproportionate anger. Often with changed sleep and appetite.
Points to This is the description of depression in men as often as it is anything else, and it belongs with a clinician rather than with a pattern.
What the patterns describe
The traditional distinction is between constraint and fire, and it is a distinction about movement. Constraint is anger that is not moving — held, distending, producing tightness rather than heat. Fire is anger that has moved upward — sudden, hot, with headache and a red face. The measures differ: constraint is addressed by dispersing and by reducing load, fire by cooling and by settling. Warming the first is reasonable; warming the second is not.
The second useful distinction is whether the irritability is proportionate. Anger that arrives when something frustrating happens is not a symptom. Anger that arrives before the frustrating thing, or that is out of all proportion to it, or that the person themselves finds alien, is more interesting. The tradition has no word for that distinction, and it is the one that decides whether this is a page about patterns or a page about assessment.
A note on what the classical material actually says. The line quoted below is not a description of irritability as a mood — it is a statement in a list of organ pairs, saying that when liver qi is excess the result is anger. It sits alongside statements about the kidney and the lung in the same structure, and its point is systematic rather than clinical. Reading it as a diagnosis of an irritable person is already a step beyond the text.
Which patterns it belongs to
These are the patterns this symptom is conventionally grouped under. They are not competing diagnoses — most people meet one, and the point of the list is to show you which questions separate them.
Irritability with rib-side tightness, sighing, belching, worse before a period, a wiry pulse.
The standard reading for held-in irritability with tightness.
Read the pattern page →Bitter taste, a yellow greasy tongue coat, heavy limbs, dark urine, a slippery rapid pulse.
Irritability with a bitter taste, a greasy coat and a heavy feeling.
Read the pattern page →Night sweats, five-palm heat, a dry mouth, broken sleep, a red tongue with little coat.
Restless irritability with heat and broken sleep.
Read the pattern page →Palpitations, poor sleep with vivid dreams, pallor, a thin pulse, a pale tongue.
Irritability with a low threshold and a sense of being easily startled.
Read the pattern page →The signs behind it
Each line below is one entry in the sign table — the same table the self-check draws its follow-up questions from. The tier says how strongly that sign points at the pattern: a defining sign is expected, a common one is usual, a supporting one is optional.

- Mood drop before the period Liver qi stagnationcommon ·Blood deficiencysupporting
Not every sign listed here will apply to you — a sign only counts alongside the others. The self-check is the place to weigh them against your own answers.
Telling them apart
Four questions do most of the work. Each one splits the field in half, and after two or three the pattern is usually clear enough to act on — or clear enough to know that the answer is medical rather than traditional.
| Question | If yes | If no |
|---|---|---|
| Is the anger held in or released upward? | Held, with tightness and sighing → constraint. Dispersing measures and load reduction. | Sudden, hot, with headache and a red face → fire. Cooling measures, and check blood pressure. |
| Is it proportionate to what happened? | No, and others have noticed a change → assessment comes before any pattern reading. | Yes, it fits the situation → this is not a symptom, whatever the pattern pages say. |
| Is there heat — night sweats, palpitations, a dry mouth? | Yes → yin deficiency with empty heat. Do not use warming tonics. | No heat signs → constraint or blood deficiency. |
| Is there low mood or numbness between episodes? | Yes → this is the presentation that belongs with a clinician. Pattern work is not the first step. | Mood normal between episodes → pattern work is reasonable. |
What you can do at home
None of this treats a named condition, and none of it replaces assessment. These are the ordinary measures attached to this symptom — low risk, and worth doing while you work out what is actually going on.
- Lengthen the exhale. Two minutes of breathing out for longer than you breathe in changes the physiological side of irritability more reliably than trying to think differently about it.
- Move daily, and outdoors if possible. Held anger responds to physical discharge in a way that talking about it often does not.
- Move the last coffee earlier, and count how much of it there is. Caffeine is the most common chemical cause of a lowered threshold and it is invisible because it feels like baseline.
- If irritability tracks the menstrual cycle, note it for two cycles rather than acting on one. The pattern across the month is what makes it readable, and it is what any clinician will ask for.
- If others have commented on a change before you noticed one, take that as the signal to have it looked at. Irritability is one of the few symptoms where the outside view is more reliable than the inside one.

肝藏血，血舍魂，肝气虚则恐，实则怒。 gān cáng xuè, xuè shě hún, gān qì xū zé kǒng, shí zé nù
The liver stores blood, and blood houses the hun. When liver qi is deficient there is fear; when excess, anger.
肝病者，两胁下痛引少腹，令人善怒。 gān bìng zhě, liǎng xié xià tòng yǐn shào fù, lìng rén shàn nù
In liver disease, pain below both flanks pulls at the lower abdomen, and the person is easily angered.
阳气者，大怒则形气绝，而血菀于上，使人薄厥。 yáng qì zhě, dà nù zé xíng qì jué, ér xuè yù yú shàng, shǐ rén bó jué
As for yang qi: great anger cuts off form and qi, blood congesting above, and the person suffers a sudden collapse.
The first citation is a line in a systematic list — liver, spleen, heart, lung, kidney, each paired with a deficient and an excess emotion. Its purpose is to place anger within a scheme, not to describe an irritable patient. The third is the one with clinical weight: it describes a sudden collapse after great anger, which is recognisable as a hypertensive or cerebrovascular event. That is the classical tradition taking anger seriously as a physical cause, and it is a better argument for checking blood pressure than any pattern reading.
