Gas and Shoulder Pain After Hysterectomy: Why It Happens, How Long It Lasts and What Helps

Many women are surprised that one of the most painful parts of the first days after a hysterectomy is not the incisions, but trapped gas and a sharp ache at the top of one or both shoulders. Both are very common after keyhole (laparoscopic) and robotic surgery. Shoulder-tip pain affects up to 80% of women after gynecological keyhole surgery.^[1] It is usually short-lived, but it can be intense enough to make breathing deeply or lying flat uncomfortable.

This guide explains why the gas ends up in your shoulder, how long it usually lasts, what actually helps, why gas pains can come back two to six weeks after surgery, and the warning signs that mean shoulder or belly pain is not just gas. It is based on a Cochrane review, published studies and patient information from the Royal College of Obstetricians and Gynaecologists (RCOG), the NHS, MedlinePlus and the CDC. For the puffy, bloated belly that often comes with it, see our guide to swelly belly after a hysterectomy.

Key points

• In keyhole and robotic surgery, the belly is filled with carbon dioxide gas so the surgeon can see and work. Leftover gas can irritate a nerve under the diaphragm, and the brain feels this as pain in the shoulder.^[1]
• Shoulder pain usually settles over 24 to 48 hours as the gas is absorbed. The more gas left behind, the stronger the pain tends to be.^[4][6]
• Trapped wind in the belly comes mainly from the bowel slowing down after surgery. It eases once your bowels start moving again.^[2][3]
• Walking, taking your pain relief as prescribed and peppermint water or tea are the simplest measures. Chewing gum may help the bowel wake up sooner.^[2][3][10]
• Gas pains a few weeks later are usually linked to constipation, pain medicines, laxatives or diet, not to the surgical gas, which is long gone by then.^[11][12]
• Shoulder or chest pain with shortness of breath, dizziness or fainting is an emergency: call 911.^[14][15]

Why gas causes shoulder pain after a hysterectomy

During a laparoscopic hysterectomy or a robotic hysterectomy, the surgeon gently inflates your abdomen with carbon dioxide. This lifts the abdominal wall away from the organs and creates room to operate safely. Most of the gas is let out at the end of the operation, but some usually stays inside for a while.

That leftover gas rises toward the highest point of the abdomen, just under the diaphragm, the dome-shaped breathing muscle below your lungs. There it is thought to irritate the phrenic nerve, which runs from the diaphragm up to the neck. Because this nerve shares its roots with the nerves that supply the skin over the shoulder, the brain reads the irritation as shoulder pain. This is called referred pain.^[1] That is why the shoulder can hurt even though nothing is wrong with the shoulder joint itself.

A study of 203 women having keyhole surgery for non-cancer gynecological conditions measured the gas left in the abdomen with a chest X-ray 24 hours after surgery. The more gas that remained, the stronger the shoulder pain, and women with less gas needed fewer painkillers and went home sooner.^[6]

Shoulder-tip pain and trapped wind are two different things

People often say “gas pain” for both, but they have different causes:

• Shoulder-tip pain comes from the carbon dioxide used to inflate the abdomen. It sits in the space around the bowel, not inside it, so you cannot pass it as wind. Your body absorbs it.
• Trapped wind is ordinary gas inside the bowel. After an operation the bowel may slow down for a while, so wind builds up and causes cramping or a tight, full feeling until it passes.^[2][3] This can happen after any type of hysterectomy, including open abdominal and vaginal surgery.

If you had a purely vaginal hysterectomy or an open abdominal one, the abdomen is not filled with gas in the same way, so shoulder-tip pain is less expected. Trapped wind can still happen. If you are not sure which technique was used, ask your surgical team or check your discharge papers.

How long does gas and shoulder pain last after a hysterectomy?

Everyone is a little different, but patient information from hospitals describes a fairly consistent pattern:

• Shoulder-tip pain: usually worst in the first day after surgery and settling over 24 to 48 hours as the remaining gas is absorbed.^[4]
• Trapped wind in the belly: most noticeable in the first few days, until the bowel gets going again. Once your bowels start to move, it eases.^[2][3] After surgery the colon is usually the last part of the gut to recover, often within about three days.^[9]
• Bloating and general belly discomfort: can come and go for longer, especially if you are constipated or taking opioid pain medicine. See our week-by-week recovery guide for how this fits into the wider recovery.

What matters most is the direction of travel. Shoulder pain that fades a little each day is typical. Shoulder pain that gets worse after the first couple of days, starts suddenly several days after surgery, or comes with any of the warning signs below needs to be checked.

What helps gas and shoulder pain at home

Get up and walk, little and often

Moving is the most consistent advice in hospital leaflets. Getting out of bed and walking around helps trapped wind, and the more you move, the sooner the remaining gas clears.^[2][3][4] Short, frequent walks around the house or along the hospital corridor are enough at first. Walking also helps prevent blood clots in the legs.^[3]

Take your pain relief as prescribed

Hospital guidance advises taking the painkillers you are given when you need them, rather than waiting for the pain to build, and never going over the stated dose. Good pain control makes it easier to get out of bed, stand up and walk, which in turn helps the gas move.^[3] If your pain medicine is not helping your pain, MedlinePlus advises contacting your surgeon.^[8]

Peppermint water or peppermint tea

RCOG patient information says peppermint water may ease the discomfort of trapped wind.^[2][3] The evidence is modest, but it is a simple, low-risk thing to try. A warm cup of peppermint tea is an easy alternative if you prefer it.

Chewing gum in the first days

A Cochrane review of 81 trials found some evidence that chewing gum after surgery helps people pass wind and open their bowels sooner, with few side effects. Most of the trials were after bowel surgery or cesarean section, and many had a high or unclear risk of bias, so the benefit after a hysterectomy is likely to be small.^[10] Ask your team if it is fine for you. Later on, once your bowel is working again, chewing gum can actually add gas by making you swallow air (see below).^[11]

Keep your stools soft

Constipation makes gas and bloating worse. Drinking plenty of water and eating fruit and vegetables helps, and you may be sent home with a laxative or stool softener.^[8] Our guide to constipation and your first bowel movement after a hysterectomy covers this step by step.

Comfort measures for the shoulder

Some women find that a warm (not hot) pack on the shoulder, changing position often, or resting propped up on pillows rather than lying completely flat makes the ache easier to bear. These measures have not been tested in good trials, so think of them as comfort, not treatment. Do not put heat on skin that feels numb, and never sleep on a heating pad. Our article on how to sleep after a hysterectomy has more ideas for getting comfortable in bed.

Ask before adding over-the-counter gas remedies

Over-the-counter products for gas are widely sold, but they will not remove the carbon dioxide that causes shoulder-tip pain, which sits outside the bowel. For trapped wind, check with your pharmacist or surgical team before taking anything new, especially while you are on prescription pain medicine.^[11]

What your surgical team can do to reduce shoulder pain

Several simple steps during surgery can reduce shoulder-tip pain. A Cochrane review of 32 trials with 3,284 women found low- to moderate-quality evidence that these may help:^[1]

• Releasing the gas more completely at the end of surgery, for example with a “pulmonary recruitment maneuver”: the anesthetist gives a few deep, controlled breaths through the breathing tube, which helps push leftover gas out of the abdomen.
• Leaving a small amount of saline (salt water) in the abdomen at the end of the operation.
• Placing a temporary drain for a short time after surgery.
• Local anesthetic placed in the abdomen (but not when it is placed only under the diaphragm).

The same review found that warmed, humidified gas probably makes little or no difference, and that gasless surgery may cause more shoulder pain rather than less.^[1] A later network meta-analysis of 11 trials with 1,111 women found that a recruitment maneuver, alone or combined with saline, was a promising way to reduce shoulder pain in the first 48 hours, with no extra side effects in the trials.^[7] Not every technique suits every patient, but it is reasonable to ask your surgeon or anesthetist before the operation what they do to reduce shoulder pain.

Gas pains 2, 3, 4 or 6 weeks after a hysterectomy

By two weeks after surgery, the carbon dioxide used during the operation has long been absorbed. Gas pains that start or continue in the following weeks usually come from the bowel itself. Common reasons include:

• Constipation, often linked to opioid pain medicines, less movement and changes in eating.^[8][9]
• Laxatives: some, such as lactulose, commonly cause wind, bloating and stomach ache. The wind usually eases after a few days.^[12]
• A sudden increase in fiber. Fiber helps prevent constipation, but foods such as beans, lentils, cabbage, broccoli and some high-fiber products also produce more gas.^[11]
• Swallowed air from chewing gum, fizzy drinks, drinking through a straw or eating quickly.^[11]
• Sugar-free sweets and drinks with sweeteners ending in “-ol” (such as sorbitol), and foods with lactose if you are sensitive to it.^[11]

Smaller, more frequent meals, eating slowly and cutting back on the foods that seem to trigger your symptoms can help.^[11] Keep up your daily walks, building up gradually; our guide to exercise after a hysterectomy explains how to increase activity safely.

Gas pain should not be getting steadily worse weeks after surgery. New belly pain that is increasing, pain on one side that hurts when you breathe in, or pain with fever, vomiting or a swelling belly should be checked by your surgical team rather than put down to gas.

Gas and bloating months or years later

Excess gas that starts long after you have recovered is usually caused by something other than the hysterectomy, such as diet, constipation, food intolerances or irritable bowel syndrome.^[11] Internal scar tissue (adhesions) can occasionally cause pain or, rarely, a bowel blockage. Our articles on swelly belly and cramps years after a hysterectomy go through the possible causes.

Persistent bloating is also one of the main symptoms of ovarian cancer. The NHS advises seeing a doctor if you have bloating, belly or pelvic pain, feel full quickly or need to urinate more often on most days, roughly 12 or more times a month.^[16] These symptoms usually have a harmless cause, but they should be checked, whether or not your ovaries were removed.

Warning signs: when it is not just gas

Shoulder and belly pain after surgery are usually harmless, but a few other conditions can feel similar at first. Because of this, know which symptoms need action.

Call 911 if you have

• Sudden shortness of breath, chest pain that gets worse when you breathe in or cough, a fast or irregular heartbeat, or coughing up blood. These can be signs of a blood clot in the lungs, which is more likely after surgery.^[14]
• Chest pressure or discomfort, or pain spreading to one or both arms or shoulders, the back, neck or jaw, especially with shortness of breath, nausea, a cold sweat or unusual tiredness. Women having a heart attack often have less typical symptoms, and shoulder pain can be one of them.^[15]
• Feeling faint, dizzy or very weak, fainting, or a racing heart, with belly or shoulder pain. These can be signs of internal bleeding.

Call your surgeon or the hospital the same day if

• You cannot pass any gas or have a bowel movement.^[8]
• You have nausea or vomiting, or cannot eat or drink.^[8]
• Your belly keeps getting more swollen, harder or more painful instead of slowly improving.
• You have a fever above 100.5°F (38°C).^[8]
• Your pain medicine is not helping your pain, or shoulder pain is getting worse rather than better after the first couple of days.^[8]
• It is hard to breathe, or you have a cough that does not go away.^[8]
• You have swelling or redness in one leg.^[8]

Increasing belly pain with fever, vomiting or not being able to pass wind matters because a bowel injury, although uncommon, is not always obvious during the operation. A systematic review of keyhole gynecological surgery found bowel injuries in about 1 in 769 operations, and in 41% of those the diagnosis was delayed by more than a day.^[13] Your other discharge instructions, such as heavy vaginal bleeding or signs of infection, still apply; see our guide to vaginal cuff healing for those.

Questions to ask your surgical team

• Will my operation be done by keyhole, robotic, vaginal or open surgery, and should I expect shoulder pain?
• What do you and the anesthetist do at the end of surgery to reduce leftover gas?
• Which pain medicines should I take at home, how often, and for how long?
• Should I take a laxative or stool softener, and what should I do if it gives me wind or cramps?
• Is it fine for me to chew gum or drink peppermint tea in the first few days?
• Who do I call, day or night, if the pain gets worse or I cannot pass gas?

It also helps to pack a few comfort items for the hospital stay, such as loose clothing and peppermint tea bags; see our hospital packing list for a hysterectomy.
