What is it?

Runner’s stomach, also known as exercise-induced gastrointestinal⁣ distress, is⁣ a term used to describe ⁢the discomfort or pain experienced in the abdomen during or ⁢after running. It can⁢ manifest as cramps, bloating, ‌nausea, or an urgent need to ​use the bathroom. This issue is especially common among long-distance runners or those engaging in intense workouts. The exact causes can vary from person to person, but it is often ⁢related to the jostling and impact of running that affects the gastrointestinal tract.


– Mechanical‍ stress: The repetitive ‌jarring motion of running can​ cause the intestines ⁢to bounce, leading to irritation and discomfort. -‌ Reduced blood flow: During exercise, blood ⁢flow is redirected away from the⁣ digestive system to⁣ the muscles, which can result ‌in decreased oxygen⁢ and nutrient supply to the gut,‌ causing gastrointestinal distress. – Diet and hydration: Consuming⁢ high-fiber or high-fat foods before a run, or not hydrating adequately, can lead ‍to digestive issues while running. – Stress and​ anxiety: Nervousness before a race, or the body’s response to stress, can contribute to an upset stomach⁣ during⁢ running.

Digestive Changes

When we engage in physical activity, the body undergoes a⁤ series of changes to support muscle function. These changes can also affect ‍digestion,‌ leading to runner’s stomach. Some common digestive changes that occur during exercise⁢ include: – Increased acid production: Stress‍ hormones released during exercise can increase the production of stomach acid, leading to heartburn and discomfort. – Slowed digestion: The ​body diverts energy away from digestion to support the muscles, causing food to move slowly through the digestive system and potentially leading to bloating and cramping. – Increased gas production:‌ Intense exercise can​ result in the production of excess gas in the intestines,‍ leading to bloating and discomfort.

Management Tips

To prevent or alleviate runner’s stomach, ⁤try incorporating these tips into your routine: – Allow⁣ time‌ for digestion: ⁣Avoid eating a large meal two to three hours before running to give your body enough time to digest. – Choose appropriate pre-run foods: Opt for⁢ easily digestible carbohydrates like bananas or toast with⁣ nut butter ⁢rather than ‍high-fiber ‌or fatty foods. – Stay hydrated:⁢ Drink‍ sufficient water before, ⁣during, and after your run‍ to maintain ⁢proper hydration. – Gradually increase intensity: Build‍ up your endurance ‌gradually to ‌give your body time to adapt and⁣ reduce the likelihood‍ of gastrointestinal distress. – Experiment ⁢with timing:⁣ Try running ‍at different ⁣times⁢ of the day to⁣ see if your digestive system responds better​ to exercise at certain times. – Manage⁣ stress: Engage in activities such as deep breathing, meditation, or yoga ‍to ⁣reduce stress levels before running.

Upset ​Stomach after running

If you ⁣experience an upset⁤ stomach ⁢after‌ running, there are a few steps you can‍ take ⁤to⁢ ease your discomfort: – Rest and hydrate: Allow your body time to recover and rehydrate after ⁤your run. Sipping on water or ‌an electrolyte drink can help replace ​lost fluids. – Avoid excessive food intake: Eating large quantities of food immediately after running ‍may worsen your symptoms. Stick​ to light, easily​ digestible snacks or meals. -‍ Gentle stretching: Perform some gentle post-run⁢ stretches to help​ relax ⁣your muscles and aid ⁣digestion. – Over-the-counter remedies: Over-the-counter medications⁢ such as antacids or ⁣gas-relieving ‌tablets may provide temporary relief from‌ symptoms.

When to seek doctor help

While runner’s stomach is typically not ‍a cause for ⁣concern, there are instances⁤ where medical attention may be necessary. Seek help from a healthcare professional if you experience: – Persistent and‌ severe abdominal⁤ pain – Blood in your stool or vomit – Unexplained ⁣weight loss or loss of appetite – Ongoing gastrointestinal symptoms that do not subside with lifestyle‍ changes


Runner’s ​stomach, or exercise-induced gastrointestinal distress, is a ‍common issue that ‌many runners face. It⁤ can occur during or ​after⁢ a run ​and manifest as cramps, bloating, or nausea. The causes of runner’s stomach include mechanical stress, reduced blood flow,⁢ diet, and⁣ stress/anxiety. Digestive changes during exercise,​ such as increased acid production and‌ slowed digestion, ⁣can contribute to this discomfort.⁢ Managing runner’s‌ stomach involves making dietary‌ adjustments, hydrating adequately, and‌ giving your body time to​ adapt. Remember, while runner’s stomach is often self-manageable, seek medical help⁣ if symptoms persist or⁢ worsen.
