Stitches: a real pain in the side

Updated: Jun 15

The dreaded side stitch, it feels like it can attack at any time, and often results in the sufferer, gasping for air and keeling over in pain! Not only do they hurt, but your performance can suffer as a result! So what are “stitches”? What can you do to relieve them? And what can you do to prevent them?

Also known by the medical name of Exercise-related transient abdominal pain (ETAP), the sharp, stabbing, or cramping pain is usually felt in the mid-outside abdomen near the ribs, although it can occur in any region of the abdomen. Rarely they can also give pain in the tip of the shoulder.


Approximately 70% of runners report experiencing the pain in the past year and in a single running event approximately one in five participants can be expected to suffer the condition, so no doubt many of you have suffered this affliction! (Morton, D et al 2015) . Even well-trained runners and athletes are not immune from this condition, although they tend to experience them less frequently.


What causes stitches?

Whilst the exact cause is often unknown, some of the leading theories include ischemia (lack of blood supply) to the intestines, irritation to the intercostal nerves (potentially aggravated by poor posture), irritation to the parietal peritoneum (tissue covering the inside of the abdomen)


How to prevent side stitches?

  • Nutrient Timing: Avoid eating large meals, fatty foods or dairy products 1-2 hours before exercise (Morton et al 2005). Also avoid large volumes of fluid, especially high carbohydrate, carbonated drinks (Morton et al 2004)

  • Breathing: exercises designed to promote belly breathing (rather than chest breathing) may help

  • Thoracic mobility: warming up prior to running with some exercises designed to improve movement in the mid-back (Morton et al 2004). Check out some of our top exercises to improve your mid-back mobility in the video below. Manual therapy may also assist improve thoracic mobility.

  • Improving fitness: whilst still occurring in fitter individuals, stitches are less common.

  • Getting older: not something you can just do, but stitches actually become less prevalent as you age. Author McCrory comically advocated “grow old, as stitches are less common with aging”. (McCrory 2007).

What to do if you get a stitch?

So there are a number of things that you can try when you get a stitch to try and relieve it:

  1. Take some slow deep breaths, focusing on breathing into the abdomen and not the chest. Try breathing through pursed lips to also encourage this.

  2. Try and stretch the painful area

  3. Bend forwards

  4. Push on the sore spot

  5. If all else fails then you may need to stop exercising!

So whilst the exact cause of your stitch may not be able to be identified, there are a number of things that you can do to prevent them, and if they happen to still come on, try the relieving techniques identified above.
