Experiencing abdominal pain while running is a common occurrence. Many people describe this discomfort as a sharp sensation in their side, often leading them to wonder if their liver is the source of the pain. This sensation is typically not related to the liver but rather to a common condition experienced by athletes. Understanding the true nature of this pain can help runners manage and prevent it more effectively.
Decoding the Discomfort: It’s Likely Not Your Liver
The pain commonly felt during running and often attributed to the liver is almost always Exercise-Related Transient Abdominal Pain (ETAP), widely known as a “side stitch.” This pain presents as an intense, stabbing sensation under the lower edge of the ribcage, though it can also feel like a dull ache, pulling, or cramping. While it frequently occurs on the right side of the upper abdomen, it can manifest on the left side or even extend to the shoulder tip. Side stitches are a widespread occurrence among those who engage in repetitive torso movements like running.
Common Factors Contributing to Exercise-Induced Abdominal Pain
While the precise cause of ETAP remains unclear, several theories explain why runners experience side stitches. One theory points to the irritation of the parietal peritoneum, the lining of the abdominal cavity. The repetitive jarring motion of running can cause friction and irritation in this membrane, leading to the localized pain.
Another mechanism involves stress on the visceral ligaments that connect abdominal organs to the diaphragm. The continuous up-and-down movement during running can pull on these ligaments, causing discomfort. Poor breathing techniques, such as shallow breathing, may also contribute by limiting the diaphragm’s full range of motion or causing spasms.
Consuming food or sugary beverages too close to exercise is another common trigger. A full stomach requires increased blood flow for digestion, potentially diverting blood away from the diaphragm and abdominal muscles. Sugary drinks can exacerbate this effect. Dehydration can also play a role, as inadequate fluid intake may contribute to muscle cramps.
Practical Strategies for Prevention and Relief
Implementing specific strategies can help prevent side stitches and alleviate them if they occur. Proper breathing technique is a significant factor; focusing on deep belly breathing rather than shallow chest breaths can help stabilize the diaphragm and reduce strain. Taking controlled, measured inhales and exhales can be beneficial.
An adequate warm-up before exercise prepares the body for activity by gradually increasing blood flow and muscle temperature. This can include light cardio and dynamic stretches. Strengthening core muscles also provides better support for the abdominal organs and diaphragm, potentially reducing the pulling on ligaments during runs. Avoiding large meals or sugary drinks for at least two to three hours before exercise allows sufficient time for digestion.
If a side stitch develops during a run, slowing down or walking can help reduce the intensity of the pain. Gentle stretching, such as side bends or reaching the opposite arm overhead while bending towards the painful side, can help stretch the affected area and diaphragm. Applying gentle pressure with fingers on the painful spot while bending slightly forward may also provide relief. Staying adequately hydrated throughout the day is also beneficial for preventing muscle cramps.
When to Consult a Healthcare Professional
While side stitches are common and generally harmless, certain symptoms warrant a consultation with a healthcare professional. If abdominal pain is persistent and unrelated to exercise, or if it is severe and does not improve with typical relief strategies, medical evaluation is advisable. Pain accompanied by other concerning symptoms, such as fever, vomiting, jaundice (yellowing of the skin or eyes), or unexplained weight loss, could indicate a more serious underlying condition.
