Bloating

Most people know the feeling: a belly that seems to fill like a balloon, a waistband that was comfortable at breakfast and tight by mid-afternoon, a sense of pressure or trapped wind that will not move along. It can sit high under the ribs as fullness after only a few mouthfuls, or lower down around the navel as a gurgling, swollen ache. Some people look visibly larger by evening; others feel tight without any change to see.

The everyday triggers are familiar. Meals eaten quickly or late, large portions, fizzy drinks, certain beans and vegetables, long stretches of sitting, constipation, a tense or hurried day, and the days before a period all come up again and again in conversation. Bloating also travels with conditions that a doctor names, such as functional dyspepsia (a sensitive, slow-feeling stomach without a structural cause) and irritable bowel syndrome.

None of this is a diagnosis, and this page offers none. Bloating is usually ordinary and passing, but it is also a symptom that occasionally carries a message, which is why the warning signs further down matter more than any point on the map. Read the rest as background for your own habits, and for a better conversation with a professional if the pattern worries you.

Chinese medicine places the stomach and spleen at the centre of digestion. The stomach receives food and is meant to send it downward; the spleen, in the classical picture, transforms what is eaten and carries its usefulness onward. When that downward and onward movement falters, the tradition speaks of qi becoming stuck, and a full, distended belly is one of the plainest signs it describes. The nursing protocol of the China Association of Chinese Medicine treats this as distension and fullness of the stomach, a symptom it nurses within its care plan for chronic gastritis.

The protocol sorts people into patterns rather than one picture. Liver and stomach qi stagnation describes fullness that swells with frustration or worry, with belching and tightness under the ribs. Spleen and stomach qi deficiency describes fullness that is worse after eating, with tiredness, a poor appetite and loose stools. Damp heat describes a heavy, stuffed feeling with a bitter taste and little hunger. A 2025 Chinese expert consensus on functional dyspepsia uses similar language, naming spleen deficiency with qi stagnation and disharmony of liver and stomach among its common patterns.

The points on this page come from that framework. Zhongwan (CV12) is the gathering point of the stomach on the front of the body, and its classical uses lead with stomach ache, abdominal distension and hiccups. Tianshu (ST25), the gathering point of the large intestine, was traditionally used for abdominal pain, distension and constipation. Qihai (CV6), the sea of qi below the navel, was used for abdominal pain and for weakness from qi deficiency. Zusanli (ST36) was used for stomach ache, vomiting and distension, and neiguan (PC6) for nausea, vomiting and hiccups. In this site's words, each was traditionally used for these complaints; that is a report of historical practice, not a claim of proven results.

Zhongwan (CV12) sits on the midline of the upper belly, four cun above the centre of the navel, halfway between the navel and the point where the lower ribs meet at the bottom of the breastbone. Lie on your back with the knees bent, find both landmarks with a fingertip, and settle in the soft middle between them. Tianshu (ST25) lies two cun either side of the centre of the navel; in hand terms, lay three fingers flat beside the navel and the outer edge marks the spot, one on each side.

Qihai (CV6) is on the midline below the navel, one and a half cun down, which is about the width of two fingers laid flat under the navel. This is the point to leave out entirely during pregnancy. All three belly points sit over soft organs rather than bone, so they are found with the flat of the fingers and met with patience, never pushed into.

Zusanli (ST36) is on the front of the lower leg, three cun below the outer hollow under the kneecap. Cup the kneecap, let four fingers rest below its lower edge, and move about one finger-width outward from the sharp crest of the shin; the point usually answers with a pleasant ache. Neiguan (PC6) is on the inner forearm, two cun above the wrist crease, between the two tendons that stand up when you make a fist and bend the wrist slightly; three finger-widths up from the crease is a quick guide.

Choose a time when you are not straight from a large meal, and lie on your back on a bed or a mat with a pillow under the knees so the belly can soften. Warm your hands first. Rest one palm over the navel, take a few slow breaths, and then begin with the step the nursing protocol recommends for a distended stomach: slow clockwise circles with the flat of the hand, moving up the right side of the belly, across under the ribs, and down the left side. A few minutes is plenty; the pressure is the weight of the hand, not a push.

Then the three belly points. Rest the flat fingers of one hand on zhongwan (CV12) and let them sink in slowly with each breath out, light to moderate, for about a minute. Move to tianshu (ST25) on both sides at once with two or three fingers each side, making small slow circles. Finish the belly with qihai (CV6), a warm palm or soft fingertips held still for about a minute; skip it if you are pregnant. Sit up for the last two: thumb pad on zusanli (ST36) below each knee, firm but comfortable, for about a minute a leg, and then neiguan (PC6) on each wrist, to comfortable depth for about a minute before swapping sides.

The stop rules matter more than the order. Stop at once on sharp, cramping or spreading pain, and never press into a belly that feels hard, tender to light touch, or newly swollen. Skip broken skin and any recent surgical wound. Once or twice a day is a sensible rhythm, and missing days costs nothing. If a session leaves you more uncomfortable than before, let it rest and see the warning signs below.

The Chinese authority behind this page is the 2026 nursing protocol of the China Association of Chinese Medicine. For a distended stomach it recommends clockwise abdominal massage, and in the same care plan it names zhongwan, tianshu and qihai for point massage; elsewhere in the protocol, for a bloated belly with poor appetite, it names zusanli, zhongwan and neiguan for point massage. The 2025 Chinese expert consensus on functional dyspepsia lists zusanli, zhongwan, neiguan and tianshu among its common points and describes clockwise abdominal massage.

The research is mostly needling, not pressing by hand. A trial published in 2020 needled a set that included all five of this page's points in adults with postprandial distress syndrome, a form of functional dyspepsia whose cardinal symptoms are fullness, upper-belly bloating and feeling full early. More people improved with real needling than with sham needling, and the difference held through three months of follow-up. That trial used needles, not fingers.

Two trials pressed by hand. A 2025 trial taught people with diarrhoea-predominant irritable bowel syndrome to press zhongwan, tianshu, zusanli and another leg point at home, and their overall symptom scores, a scale that includes bloating, improved more than with pressing sham spots. A 2023 trial of nurse-delivered pressing at zusanli after bowel cancer surgery found that wind passed sooner, but belly distension was no different from light skin rubbing. A Cochrane review of needling for irritable bowel syndrome found no clear advantage of real over sham needling in its sham-controlled trials.

Some bloating is a message rather than a nuisance. If you are a woman aged 50 or over and bloating has become persistent or frequent, most days or on and off for weeks, see a doctor and ask about checks for the ovaries; this is a recognised early sign worth ruling out, and it is easy to dismiss as indigestion. See a doctor promptly, too, for bloating with unexplained weight loss, blood in the stool or black stool, anaemia or unusual tiredness, trouble swallowing, persistent vomiting, or a lump you can feel in the belly.

New digestive symptoms that begin in later life deserve a check rather than a routine: many guidelines draw that line at around 55, and the Chinese consensus draws it earlier still. Seek urgent help for severe belly pain, or for a swollen, tight belly while passing no wind and no stool, which can mean the bowel is blocked; that is especially important after any abdominal surgery. During pregnancy, new or painful bloating belongs with your midwife or doctor before any self-care.

Between emergencies and ordinary passing bloating lies the wider ground of bloating that simply keeps coming back. That too deserves a proper assessment, so that conditions such as coeliac disease, constipation or irritable bowel are not missed. Persistent symptoms belong with a licensed practitioner — Western medicine or East Asian medicine, whichever suits the complaint.

The nursing protocol never leaves the points to work alone. Its care for a distended stomach asks people to notice when the fullness comes and what sets it off, to walk a little after meals, to keep the bowels moving, to avoid eating to the point of being stuffed, and to keep the mood easy rather than angry or downcast. Those are old instructions, and they read as plainly modern.

Everyday versions are simple: eat more slowly and stop before you are full, go easy on fizzy drinks, notice whether particular foods seem to set things off, drink enough water, and take a short walk after the main meal. A food and symptom diary for a couple of weeks often teaches more than any single change. A few quiet minutes with a warm hand circling the belly may be the most pleasant part of the evening, and that pause is worth keeping for its own sake.

Why does the routine start with circles on the belly rather than a point?

Because it is the part of the Chinese nursing advice that belongs at home. For a full, distended stomach the protocol this page follows recommends clockwise massage of the abdomen alongside clinic techniques such as herbal patches and moxa, and an expert consensus on indigestion describes the same clockwise sweep with a few points pressed along the way. Clockwise, seen from your own eyes looking down, follows the direction the large bowel travels, which is why the habit has lasted.

Is it safe to press the belly when I am pregnant?

Leave qihai (CV6) out entirely during pregnancy, as tradition advises, and do not press deeply anywhere on the belly. A warm palm resting lightly is as far as this page goes. Zusanli (ST36) below the knee and neiguan (PC6) on the wrist carry no such traditional bar, but pregnancy is still a reason to ask your midwife or doctor before starting, especially if the bloating is new.

How soon after a meal can I do this?

Give a heavy meal some time to settle first. Pressing into a very full stomach tends to feel worse, not better, and the nursing advice for a distended stomach also asks for smaller meals and a little gentle movement after eating. Between meals, once or twice a day, is a comfortable rhythm; the wrist and leg points can be pressed at almost any time.

What have trials found about acupressure for bloating?

A 2020 trial needled points rather than pressing them, in a kind of indigestion in which fullness and upper-belly bloating are cardinal symptoms, and more people improved with real needling than with sham needling. Two trials pressed by hand: one self-pressing trial in irritable bowel improved overall symptom scores more than pressing sham spots, and one nurse-delivered trial after bowel surgery found wind passed sooner but distension no different from light skin rubbing.

Why are a leg point and a wrist point part of a belly routine?

Classical practice paired points close to a complaint with points far away along the same channels. Zusanli (ST36) sits on the stomach channel, which old charts run from the face down through the belly to the foot, and neiguan (PC6) was traditionally used for nausea, hiccups and a stuck feeling in the chest and stomach. Both appear in the nursing protocol for poor appetite and a bloated belly.

My bloating comes and goes with my period. Is that something to worry about?

Bloating that rises and falls with the monthly cycle is very common and usually ordinary. What deserves a doctor is bloating that has become persistent or frequent, especially at 50 or over, or bloating that comes with weight loss, bleeding, or a change in bowel habit that does not settle. Mention the pattern, including any link with your cycle, so the doctor can read it properly.
