Side stitch pains are felt in the lower abdomen during physical activity. Men who enjoy running may feel pain during workouts or races. While side stitches do not require medical attention, it’s essential to understand what causes them and how they affect everyday life.
side stitch, what is a side stitch, how to avoid stitches when running
The medical term for a side stitch is exercise-related transient abdominal pain (ETAP) — you usually feel it on the lower side of your abdomen under your rib cage. A side stitch is a sharp pain on either side of the lower abdomen, which causes a cramping or pulling sensation. Sometimes a side stitch can be so painful that you have to stop the physical activity until it passes, which could take one or two minutes, depending on the extent of the pain.
There’s no sole reason why a stitch occurs but a recent study revealed that 70% of runners experience ETAP annually. The pain can occur when running or doing simple chores like walking up the stairs — one suggestion is that a side stitch is a diaphragm spasm.
While the pain is sharp and distinct, the exact cause of side stitches hasn’t been established. However, there are speculations about possible leading causes:

One of men’s most significant risk factors is running after eating a full meal. A full stomach can pull down ligaments and muscles, irritating the diaphragm. When the diaphragm feels uncomfortable, it sends pain signals to the brain.
If you’re a runner or new to running, you’re more prone to stitches if you don’t have a well-established breathing technique or strong core muscles. Your diaphragm and ligaments can experience tiredness quickly, causing your body to spasm.
If you don’t have a fitness plan and your weak core muscles are not equipped to sustain your body during exercise, you may be prone to stitches. Your body requires strong core muscles as you progress in running. If your core muscles aren’t prepared for the strain, combined with inadequate breathing — your body is more prone to getting side stitches.
While side stitches can be frustrating — especially if you’re more prone to them than others, you can control them by using these pre-training techniques:

What do you do if you get a side stitch while running? If you get a side stitch while you’re hiking or mid-run, slow down or stop. Wait until the pain subsides. Gently press your hand on the painful area and exhale deeply. This helps to relax the diaphragm and reduce discomfort. You can also bend your torso slightly forward if that helps.
Stay hydrated while running. Your body is losing fluid as you sweat, and staying hydrated helps your cognitive and body functions function properly. Avoid drinking sugary beverages before and during a run. Adjust your breathing by focusing on deep belly breathing. Inhale for three seconds and exhale for another three. This method restores your breathing rhythm and reduces strain.
If you feel the stitch worsening, listen to your body. Slow down or completely stop and try again another day. Contact your doctor if the signs suggest the pain may be more intense than a usual side stitch.
A side stitch is often frustrating and a common discomfort for runners, but understanding its causes and how to prevent it may help you in the long run. Focus on deep breathing to give your diaphragm enough air, build your core and decide when and how long you run to keep your training on track. If a side stitch does occur, slow down until your body is ready to run again.
