How to Get Rid of Gas Pain After Surgery

Gas pain after surgery is one of the most common and uncomfortable complaints patients face during recovery, and the good news is that several straightforward strategies can speed up relief. The pain comes from two distinct sources depending on the type of surgery: carbon dioxide gas deliberately pumped into the abdomen during laparoscopic procedures, and the natural slowing of your intestines caused by anesthesia and pain medications. Tackling both requires a combination of movement, simple oral remedies, and smart choices about food and medication.

Why Surgery Causes Gas Pain in the First Place

If you had laparoscopic surgery, your surgeon inflated your abdomen with carbon dioxide to create working space. Not all of that gas escapes when the procedure ends. Leftover CO2 can sit in pockets between the liver and diaphragm, irritating the lining of the abdominal cavity and the phrenic nerve. That nerve runs up toward your shoulder, which is why so many people experience puzzling shoulder or upper abdominal pain after a keyhole procedure rather than just discomfort at the incision sites.¹ One theory holds that CO2 converts to carbonic acid on the moist surface of the peritoneum, essentially creating a mild chemical irritant inside you.

The second source of gas pain applies to nearly all abdominal surgeries, laparoscopic or open. Handling of the bowel, general anesthesia, and opioid pain relievers all conspire to slow your gut to a crawl. When your intestines stop moving normally, gas produced by bacteria in your colon has nowhere to go, and it builds up. This temporary shutdown, sometimes called postoperative ileus, can leave you feeling bloated, crampy, and miserable until things start moving again.

How Long Gas Pain Typically Lasts

Residual CO2 from a laparoscopic procedure resolves on its own as your body absorbs it. In a study tracking 57 patients after laparoscopy, about half cleared all residual gas within the first 24 hours. Most of the rest resolved within three days. The average was roughly two and a half days, though a small number of patients took up to a week or slightly longer.² In that same study looking at laparoscopy for adnexal masses, the volume of residual gas correlated with how long it took patients to first pass gas on their own, suggesting that people with more trapped CO2 simply have a longer wait.¹

Intestinal gas buildup from a sluggish bowel follows a different timeline. After major abdominal surgery, most people begin passing gas within two to three days if they are moving around. If you are still unable to pass gas after three or four days, your care team will likely step in with additional treatments. The strategies below can help both the CO2-related pain and the intestinal variety, though which ones matter most depends on your specific situation.

Start Walking as Early as Your Team Allows

Getting out of bed and walking, even just shuffling down the hallway, is the single most effective thing you can do for gas pain. Movement stimulates your intestines to resume their normal rhythmic contractions. A systematic review and meta-analysis of studies following gastrointestinal surgery found that patients who mobilized early passed gas an average of about 12 hours sooner than those who stayed in bed longer.³ Across those studies, patients who got moving recovered gut function in roughly two days on average, compared with nearly three days for the less active groups.

A separate study of abdominal surgery patients found a direct relationship between mobility frequency and symptoms: as patients moved more often, their abdominal pain decreased and the time until first passing gas shortened.⁴ You do not need to power walk. Gentle, frequent movement is what matters. Aim for short walks every few hours if your surgical team gives the green light, and try to avoid long stretches lying flat.

Chewing Gum

This one sounds almost too simple, but the evidence behind it is surprisingly strong. Chewing gum tricks your digestive system into thinking food is on its way. It triggers nerve signals from your brain to your gut that stimulate intestinal movement, a process sometimes called sham feeding. A large Cochrane review of the research found that gum chewing reduced the time to first passing gas by roughly ten hours on average across different types of surgery.⁵ A more recent meta-analysis reported an even larger benefit, finding that gum chewers passed gas about 12 hours sooner and had their first bowel movement roughly 20 hours earlier than non-chewers. Hospital stays were also shorter by nearly a full day.⁶

The typical protocol in these studies has patients chew sugarless gum for about 15 minutes every two hours, starting within a few hours of surgery.⁷ It is cheap, has essentially no risks, and works alongside everything else you are doing. Pack a few packs of sugar-free gum in your hospital bag.

Apply Heat to Your Abdomen or Shoulders

A warm compress or heating pad can ease both types of postoperative gas pain. For the sharp referred pain in your shoulders from trapped CO2, a randomized trial comparing local heat application against standard care after gallbladder removal found that shoulder pain scores at 24 and 48 hours were significantly lower in the group that received heat.⁸ For intestinal gas, warmth on the abdomen relaxes the muscles of the gut wall and can ease cramping. Use a warm (not hot) pad wrapped in a towel to protect your incisions. Sessions of 15 to 20 minutes work well.

Simethicone

Simethicone is the active ingredient in over-the-counter products like Gas-X and Mylicon. It works by breaking up gas bubbles in the gut, making them easier to pass. A multicenter study of patients after laparoscopic gallbladder removal found that those who took simethicone passed gas roughly two and a half hours sooner and had better relief from abdominal bloating at both 24 and 48 hours compared to those who did not.⁹

The picture is not quite as rosy for all surgical contexts. A systematic review of treatments for bowel slowdown after cancer surgery found that simethicone given at higher doses did not meaningfully prevent gut dysfunction following colorectal resections.¹⁰ So simethicone appears most helpful for milder bloating after smaller procedures like gallbladder surgery, and less reliable after major bowel operations. Ask your surgical team whether it makes sense for your situation, and confirm that taking anything by mouth is cleared first.

Peppermint

Peppermint has been used as a digestive remedy for centuries, and there is modern evidence to back it up for postoperative gas. Peppermint oil relaxes the smooth muscle in the walls of the intestines, which can help trapped gas move through more easily. It is classified as a carminative, meaning it both prevents and helps relieve intestinal gas.¹¹ A trial in women recovering from cesarean sections found that peppermint drops significantly shortened the time to first passing gas compared with a placebo, and bowel sounds returned sooner as well.¹²

Peppermint tea is the easiest form to access in a hospital setting. A few cups a day, once you are cleared for fluids, can provide gentle relief. Some hospitals now include peppermint in their standard post-surgical care protocols.

Abdominal Massage

Gentle massage of the abdomen can help stimulate sluggish intestines. A study comparing abdominal massage to standard pharmacological care after surgery found that massage was comparable to medication in reducing indigestion, abdominal pain, and overall gastrointestinal symptom scores.¹³ The technique follows the natural path of the colon: start on the lower right side of the abdomen, move up, across, and down the left side in a clockwise direction. Use gentle pressure and avoid the incision areas. Even five to ten minutes a few times a day can make a difference, and it is something you or a family member can do without any special equipment.

What You Eat and When

There has been a shift in surgical thinking about how soon patients should eat after abdominal surgery. The old approach of keeping people on nothing by mouth until they passed gas has given way to evidence supporting earlier feeding. Research on fast-track surgical recovery programs suggests that strategies like opioid-sparing pain control and encouraged oral nutrition promote earlier return of gut function.¹⁴ When your team says you can eat, start with small amounts of easy-to-digest food. Clear broths, plain crackers, and cooked vegetables are better early choices than heavy, greasy, or high-fiber meals.

While fiber is generally good for digestion, loading up on raw vegetables, beans, or whole grains too quickly after surgery can worsen gas production before your gut is ready to handle it. Introduce higher-fiber foods gradually over the first week. Carbonated drinks, which add gas directly to your digestive tract, are also worth avoiding until you are comfortable again. Sipping warm liquids like broth or peppermint tea tends to be more soothing.

Interestingly, what you consume before surgery may also matter. A randomized trial of patients undergoing colorectal surgery found that those who drank a carbohydrate-rich beverage before their operation passed gas about five hours sooner, had their first bowel movement roughly 13 hours earlier, and began eating sooner compared with those who fasted conventionally.¹⁵ Many enhanced recovery protocols now include a preoperative carbohydrate drink for this reason, so it is worth asking your surgeon about it ahead of time.

How Pain Medication Makes Gas Worse

Here is a frustrating catch-22 of surgical recovery: the opioid painkillers often prescribed after surgery are one of the biggest contributors to gas pain. Opioids bind to receptors throughout the gut and slow intestinal movement directly. This is not a rare side effect. Survey data suggest that roughly 40 percent of patients on opioid therapy experience constipation and related symptoms like bloating and cramping.¹⁶ The more opioids you take, the more your bowel slows down, and the more gas builds up.

This does not mean you should refuse pain medication and suffer. But it does mean you should work with your team to use opioids at the lowest effective dose and switch to non-opioid alternatives like acetaminophen or ibuprofen as soon as it is safe. Many modern surgical recovery programs emphasize “multimodal” pain management precisely because reducing opioid use helps the bowel wake up faster. If you are prescribed opioids, ask about stool softeners or mild laxatives to counteract the gut-slowing effects.

What Your Surgeon Can Do During the Procedure

Some of the most effective measures happen in the operating room before you are even awake. After a laparoscopic procedure, the surgeon can actively suction out residual CO2 rather than simply releasing it passively. A trial comparing active suction to standard deflation found that the suction group retained far less gas and reported significantly lower pain scores at 6 hours, one day, and two days after surgery.¹⁷ This is a simple, low-cost technique that not every surgeon routinely uses. If your surgery is scheduled and not an emergency, asking your surgeon whether they use active gas removal at the end of the procedure is a reasonable conversation to have.

Another approach that gets attention is using warm, humidified CO2 during insufflation instead of cold, dry gas. The theory is that warmed gas causes less irritation to the peritoneal lining. Results here are mixed. One randomized trial in adults undergoing gallbladder removal found that warm CO2 did reduce shoulder pain in the days after surgery.⁸ But a trial of short gynecologic procedures found no benefit from heated humidified gas for pain, nausea, or recovery time.¹⁸ The length and type of surgery seem to matter, with longer procedures potentially benefiting more. This is not something you would typically request, but it is worth knowing about if your surgeon is discussing the procedure plan.

Putting a Strategy Together

Rather than picking one approach, the best results come from layering several of these strategies. A reasonable plan looks something like this:

Before surgery: Ask about preoperative carbohydrate drinks and whether your surgeon uses active CO2 removal.
In the first few hours: Start chewing sugarless gum every two hours. Accept help getting out of bed and take a short walk as soon as your team clears it.
Through the first day: Apply warm compresses to your abdomen or shoulders. Sip warm peppermint tea once fluids are permitted. Try gentle clockwise abdominal massage away from incision sites.
Over the next few days: Continue walking frequently. Eat small, easy meals and avoid carbonated drinks. Ask about simethicone if bloating persists. Minimize opioid use by transitioning to milder pain relievers when possible.

When to Be Concerned

Gas pain after surgery is almost always benign, but certain warning signs warrant immediate attention. If you have not passed gas at all after three to four days, if your abdomen becomes increasingly firm and distended, or if you develop vomiting, fever, or worsening pain rather than gradual improvement, contact your surgical team. These can be signs of a prolonged ileus or, in rarer cases, a bowel obstruction. Severe, unrelenting shoulder pain after laparoscopy that does not respond to heat or position changes may occasionally signal something other than trapped gas, so mention it if it seems disproportionate. For the vast majority of people, though, the discomfort peaks in the first day or two and steadily fades as the body absorbs residual CO2 and the gut wakes back up.
