The fastest way to get rid of a side stitch is to slow your pace, press your fingers firmly into the painful spot, and take slow, deep breaths. Most stitches fade within a few minutes using these techniques. Side stitches affect up to 60% of runners in a given year, so if you’ve been stopped mid-run by that sharp, stabbing pain just below your ribs, you’re far from alone.
What to Do When a Stitch Hits
The moment you feel that familiar cramp forming, slow down. You don’t necessarily have to stop completely, but reducing your intensity gives your body a chance to recover. While you slow your pace, press two or three fingers directly into the painful area and hold firm pressure there, or massage it in small circles. This alone often provides noticeable relief within 30 to 60 seconds.
At the same time, focus on deep belly breathing. Inhale slowly through your nose, letting your abdomen expand rather than your chest, then exhale fully. Some runners find that bending forward slightly at the waist while exhaling helps stretch the diaphragm and release the tension faster. You can also try flexing your abdominal muscles deliberately or even grunting as you breathe out, which forces a deeper exhalation and seems to reset the cramping pattern. Combine two or three of these techniques at once for the quickest results.
If the stitch doesn’t fade after a minute or two of this, stop and walk. Raise the arm on the side of the pain overhead, then lean gently toward the opposite side to open up the space between your ribs and hip. Hold this stretch for 15 to 20 seconds while continuing to breathe deeply. Most stitches resolve fully within two to five minutes when you’re willing to pause and address them.
Why Side Stitches Happen
Researchers still don’t have a single definitive explanation for side stitches, which are formally called exercise-related transient abdominal pain (ETAP). Several competing theories exist, and the real answer likely involves more than one mechanism. The leading hypothesis points to irritation of the parietal peritoneum, a thin membrane lining the inside of your abdominal cavity. During repetitive, bouncing movements like running, friction or tugging on this membrane could trigger the sharp, localized pain you feel.
Other proposed causes include cramping of the abdominal muscles themselves, reduced blood flow to the diaphragm during intense effort, and stress on the ligaments that connect your internal organs to your diaphragm. What is well established is that eating or drinking too close to exercise makes stitches more likely, they decrease with age and higher training volume, and they’re most common in activities involving repetitive torso movement.
Breathing Patterns That Prevent Stitches
One of the most effective long-term strategies is adopting rhythmic breathing, which distributes the impact forces of running more evenly across your body. The idea is simple: if you always exhale when the same foot hits the ground, the repeated jarring on one side of your diaphragm increases your stitch risk. Rhythmic breathing naturally alternates which foot absorbs the impact during exhalation.
The American Lung Association recommends a 3:2 pattern for easy-pace running. Inhale over three footfalls (left, right, left), then exhale over two (right, left). This creates an odd-numbered cycle that automatically shifts the exhale from one foot to the other with each breath. When you pick up the pace and need more oxygen, you can switch to a 2:1 pattern: inhale for two steps, exhale for one. Start by practicing this breathing while walking before attempting it during a run, since coordinating breath and footstrike takes some getting used to.
What to Eat and Drink Before Exercise
What you consume before a workout plays a surprisingly large role in whether a stitch shows up. Heavy meals high in fat and drinks loaded with sugar are two of the most reliable triggers. High-sugar beverages in particular seem to increase both the frequency and severity of stitches, possibly because concentrated fluids draw water into the gut and increase the weight pulling on abdominal structures during movement.
Give yourself at least one to two hours between a full meal and exercise. If you need fuel closer to your workout, stick to a small, easily digestible snack low in fat and fiber. For hydration, plain water or a lightly flavored electrolyte drink is a safer bet than fruit juice, soda, or heavily sweetened sports drinks. Sipping small amounts frequently is better than gulping a large volume right before you start.
Building Core Strength to Reduce Risk
Runners and athletes who train more frequently report fewer side stitches over time, and stronger core muscles appear to be part of the reason. A stable core reduces excessive movement of your internal organs during high-impact exercise and gives your diaphragm a more stable base to work from. Focus on exercises that target the deep stabilizing muscles of your abdomen and lower back: planks, dead bugs, bird dogs, and pallof presses are all solid choices.
Flexibility matters too. Tight muscles through your torso and hip flexors can restrict your breathing mechanics and contribute to the cramping pattern that triggers stitches. Adding a brief routine of torso rotations, side bends, and hip flexor stretches to your warm-up takes only a few minutes and addresses both flexibility and core activation before you start running.
Who Gets Stitches Most Often
Side stitches are far more common in younger athletes and less experienced exercisers. Up to 30% of participants in a community fun run will experience one during the event, and the pain is common enough to affect performance even among people who consider themselves regular runners. Swimmers, horseback riders, and anyone doing repetitive trunk rotation are also at higher risk.
The good news is that stitches become less frequent as your fitness improves. Consistent training, better pre-exercise nutrition habits, and a stronger core all compound over time. If you’re new to running and stitches seem unavoidable, gradual increases in distance and intensity will naturally reduce how often they strike. Most experienced runners deal with them only occasionally, and when they do, the techniques above clear them quickly.
