Side stitches while jogging are a common phenomenon that many runners are familiar with. This stabbing pain, usually in the diaphragm or abdominal area, can significantly impair your run and dampen your enjoyment of the activity. Most athletes experience side stitches while running at least once, as this study also confirms.

But what exactly causes side stitches, and how can you avoid them? Here, we’ve compiled the most common causes and effective measures for preventing and relieving side stitches.

What Is a Side Stitch?

Side stitches, medically known as “flank pain,” are acute, stabbing pains that typically occur in the area of the diaphragm or the lateral abdominal region. This pain can occur during physical activities such as jogging, running, or other endurance sports and is often so intense that it forces the person affected to stop the activity or slow down.

There is currently no scientific evidence regarding side stitches. Therefore, here are just a few theories about what the physiological processes behind side stitches might look like in the body:

  1. Diaphragmatic spasm: Thediaphragm is the main respiratory muscle that separates the chest cavity from the abdominal cavity. During intense physical activity, the diaphragm must contract more forcefully and frequently to meet the body’s increased oxygen demand. This constant tension can lead to spasms that are perceived as a side stitch.
  2. Redistribution of blood flow: During running or other endurance sports, blood is increasingly directed to the working muscles, particularly the legs. This redistribution can lead to reduced blood flow to the diaphragm and internal organs. Insufficient blood flow to the diaphragm can impair its function and cause pain.
  3. Irritation of the peritoneum: The peritoneum is a thin layer of tissue that lines the abdominal cavity and envelops the internal organs. During intense physical exertion, stretching or pressure on the peritoneum can cause irritation, which may result in a side stitch.
  4. Tension on the ligaments: The organs in the abdominal cavity are held in place by ligaments and bands of tissue. During intense physical activity, tension can be placed on these ligaments, especially when the stomach is full or poor posture is adopted. This tension can cause pain that is perceived as a side stitch.
  5. Gas Exchange and Bloating: While running, increased breathing and higher energy demands can lead to increased gas production in the intestines. These gases can exert pressure on the diaphragm and surrounding tissues, which can result in a side stitch.

Causes of Side Stitches

Since the topic of side stitches is generally very difficult to understand and there are many factors that influence it, the exact causes of side stitches have not yet been fully researched. There are several different causes for the onset of side stitches.

First and foremost, breathing technique plays a key role. Proper breathing techniques can therefore help prevent side stitches.

Furthermore, eating and drinking before running can influence the onset of side stitches. Undigested food in the stomach or excessive fluid intake while running can trigger this pain. Therefore, it is important not to eat heavy, hard-to-digest meals before running and to drink enough—but not too much.

Poor posture can also lead to side stitches. If the spine isn’t straight while jogging or if the running rhythm becomes irregular, this can put increased strain on the muscles, especially the diaphragm. A good tip is therefore to always maintain an upright posture and a steady running rhythm.

Side stitches are generally harmless. However, if they occur regularly, you should consult a doctor or sports medicine specialist to rule out more serious underlying conditions. The cause of side stitches is often a combination of several factors and therefore varies from person to person.

Stitch on the Right Side

Side stitches on the right side are common and can be particularly bothersome. One possible cause is a tense diaphragm. Be sure not to go jogging immediately after eating, and pay attention to your breathing.

To effectively stretch your diaphragm, sit upright in a chair. Keep your core muscles stable and take several deep breaths in through your nose. Fill your lungs completely with air until they are fully expanded, and feel your chest rise and your ribs expand.

Then open your mouth and exhale forcefully. As you do so, lean your upper body far forward to completely expel the last traces of air.

Left-sided side stitch

It is believed that a stitch on the left side is often related to the spleen. However, science has not yet been able to prove this. The spleen helps break down old red blood cells, and during intense physical activity, it can enlarge, which may lead to pain. Here, too, running slowly, proper breathing techniques, and adequate warm-up exercises can help.

Side Stitches Without Exertion

Side stitches that occur without physical exertion are unusual and could indicate health problems. While side stitches during exercise are often caused by exertion and movement, there are several reasons why this pain can also occur during periods of rest.

Possible causes

  1. Gastrointestinal problems: One of the most common causes of side stitches without exertion is gastrointestinal discomfort such as bloating, constipation, or indigestion. These can lead to pressure and pain in the abdominal area that feels like a side stitch.
  2. Irritation of the diaphragm: The diaphragm can become irritated even without physical activity. This can be caused by a variety of factors, including overeating, spicy foods, or an inflammatory condition. Gastroesophageal reflux disease (GERD) can also lead to irritation of the diaphragm and, consequently, to side stitches.
  3. Muscle tension: Tension or cramps in the abdominal muscles or diaphragm can occur regardless of physical activity. Prolonged sitting in poor posture or stress can lead to such muscle tension.
  4. Gallbladder problems: Problems with the gallbladder, such as gallstones or inflammation, can cause pain that is often mistaken for a side stitch. This pain often occurs suddenly and can be intense.
  5. Lung problems: Lung conditions, such as pleurisy (inflammation of the pleura) or infections, can cause pain in the chest or the side of the abdomen. This pain can also occur at rest and should be evaluated by a doctor.
  6. Heart problems: In rare cases, pain that feels like a side stitch may indicate heart problems, especially if it is accompanied by other symptoms such as shortness of breath, sweating, or nausea. Immediate medical evaluation is essential in such cases.

If side stitches occur regularly without exertion or are very intense, it is important to see a doctor. This is especially true if the pain is accompanied by other symptoms such as fever, nausea, vomiting, shortness of breath, or sudden weight loss. A doctor can diagnose the exact cause of the pain and recommend appropriate treatment.

How Can You Prevent Side Stitches?

Side stitches can be very uncomfortable while jogging and during other endurance sports, and they can significantly reduce the enjoyment of exercise. Fortunately, there are various measures that can help prevent this annoying problem. Here are some proven tips for preventing side stitches:

1. Proper breathing technique

One of the most common causes of side stitches is improper breathing technique. To prevent this, you should breathe deeply and rhythmically. A proven method is abdominal breathing, where you breathe deeply into your abdomen rather than just into your chest. A steady breathing rhythm can help relax the diaphragm and prevent cramps. For example, a rhythm of two steps while inhaling and two steps while exhaling can be effective.

2. Adequate Warm-Up

A thorough warm-up before running prepares the muscles and the cardiovascular system for the upcoming exertion. Gentle jogging and dynamic stretching exercises warm up the muscles, including the diaphragm, and reduce the risk of side stitches. A good warm-up routine should last about 10–15 minutes and include both dynamic stretching exercises and light aerobic activities.

3. Nutrition and Hydration

A balanced diet and proper hydration are crucial for preventing side stitches. Avoid large meals and large amounts of fluid at least 1–2 hours before running. Instead, opt for smaller, easily digestible meals. Drink in small sips and avoid carbonated beverages, which can cause bloating.

4. Posture and Running Form

Maintaining an upright posture while running can help prevent pressure on the diaphragm. The upper body should be slightly leaned forward, and the shoulders should remain relaxed. A smooth, relaxed running technique reduces strain on the abdominal and chest muscles. Make sure your arms swing in time with your steps to promote a natural and efficient motion.

5. Build Up Gradually / Reduce Pace

Overdoing it and suddenly increasing the intensity of your workout can lead to side stitches. It’s important to gradually increase the intensity of your workouts and give your body time to adjust to the increased strain. Start with shorter, less intense workouts and gradually increase the duration and intensity.

6. Relaxation Techniques

Stress and tension can contribute to side stitches. Relaxation techniques such as deep breathing, meditation, or yoga can help calm the body and mind, thereby reducing the risk of side stitches. Make sure you’re mentally relaxed before training and consciously work to relieve any stress that may arise.

Side stitches can be prevented through a combination of proper breathing technique, a thorough warm-up, an appropriate diet, good posture, and a gradual increase in training intensity. If you incorporate these measures into your training routine, you can significantly reduce the risk of side stitches, which can help you run more comfortably and successfully.

How do you get rid of side stitches?

You can take the following steps to relieve your pain and get rid of side stitches:

  • Take a break or slow down while running.
  • Breathe in deeply and exhale slowly.
  • Stretch your abdominal muscles by raising one hand above your head and bending slightly toward the side where you feel the pain. Pause in this position and gently press your fingers against the affected area while leaning your upper body slightly forward.
  • Make sure to stay well-hydrated while exercising, but avoid sugary sports drinks, as these can irritate your stomach.

A side stitch usually goes away on its own within a few minutes or after you finish exercising. However, if the side stitch does not go away even after several hours, you should seek medical attention.

Seek immediate medical attention if you experience sharp, stabbing pain accompanied by a fever or swelling on the side of your abdomen.

Myths About Side Stitches: What’s True, What’s Not?

There are now numerous myths surrounding side stitches while jogging. We’re debunking the three most common ones: 

Myth 1: “Side stitches are caused by a poor diet.” Opinions on this topic vary widely. It’s generally accepted that eating a heavy meal shortly before running can lead to side stitches. However, there’s no evidence linking specific foods or overall dietary habits to side stitches. 

Myth 2: “Side stitches are a sign of poor fitness.” Many runners assume that side stitches mainly occur in beginners or people who aren’t physically fit. However, this isn’t true. Even experienced and well-trained athletes sometimes suffer from side stitches while jogging, so it doesn’t necessarily have anything to do with your overall fitness.

Myth 3: “To avoid side stitches, you shouldn’t drink while running.” While the amount and type of fluid intake during a run can play a role, drinking while running shouldn’t be avoided as a general rule. Dehydration can also lead to side stitches, so it’s important to stay well-hydrated. Especially during training sessions that last longer than an hour, you should make staying hydrated a basic rule.

Nutrition and Side Stitches While Jogging

Nutrition plays an important role when it comes to side stitches while jogging. Poor or inappropriate nutrition can increase the likelihood of side stitches in runners. As an athlete, you surely know how important a proper, balanced diet is for your performance. 

Have you noticed that you get more side stitches when you run right after a meal? This is because your body needs a lot of energy for digestion and therefore has less to spare for your muscles. In addition, when you run, blood and oxygen are diverted from your muscles to your digestive system, which can lead to cramps.
To avoid side stitches while jogging, make sure to eat a meal at least two to three hours before running. You should avoid particularly large or high-fat meals. Light snacks, such as bananas or a granola bar, are beneficial, however.

Furthermore, hydration affects the occurrence of side stitches. Too much or too little water can also lead to cramps. Therefore, we recommend drinking a glass of water 20 to 30 minutes before running and taking small sips regularly during longer runs.

A good nutrition and hydration routine can therefore go a long way toward preventing side stitches while jogging. A mindful nutrition strategy can not only help you improve your running performance but also avoid those annoying side stitches.

Conclusion

For a pain-free running experience, it’s important to keep a few things in mind to avoid side stitches while jogging. First, you should always warm up properly before you start running. Your body needs a few minutes to adjust to the upcoming physical activity. Thorough stretching and warming up can be helpful here.

Next, pay attention to proper breathing. Frequent, shallow breathing can make side stitches worse. Therefore, make sure to take deep, steady breaths. It’s recommended to inhale through your nose and exhale through your mouth, as this promotes deeper breathing. During slow, steady runs, you can also breathe exclusively through your nose. Always try to maintain calm, controlled breathing and avoid breathing too rapidly.

Your diet also plays an important role. Avoid large meals in the two to three hours before running. In addition, it’s important to stay well-hydrated, but not immediately before jogging.

Your running form is also important. An incorrect foot strike or an uneven running motion can also lead to side stitches. Therefore, make sure to maintain an upright posture and a consistent stride length.

Finally, it’s important to maintain a positive attitude. Side stitches while running can be frustrating, but with patience and the right methods, you can successfully manage them in most cases. Remember that it’s not just about running faster and farther, but above all about having a healthy and enjoyable running experience.
