Stomach pain after working out is not just a sign of weakness. It can be caused by several factors, including overexertion, dehydration, and electrolyte deficiencies – which means you should drink more water if it’s been a while since your last sip!

While it’s always unpleasant to experience pain during or after working out, you’re not alone in experiencing stomach upset. Nausea and cramps can happen, too, no matter how to fit or young you are!

What else causes stomach issues during or following exercise? Here are some possibilities:

  • Workout Intensity:

The intensity of a workout or physical exercise directly affects the stomach. Resilient and sturdy activities can cause abdominal cramps. How hard and arduously you fitness work out directly affects how your stomach feels after such activities.

  • Exercising after having meals:

Eating a large, heavy meal prior to exercise can cause abdominal cramps and gastric discomforts. It is one of the leading causes of stomach hurt after workouts. Although eating diet foods 15-20 minutes before activities could be beneficial, filthy meals cause nausea or stomach pain during and after workouts.

  • Drinking too much water during workouts:

Usually, it is preferable to take a sip of water after each exercise set, but drinking too much water can lead to stomach hurt. Drinking too much water during exercises causes hyponatremia, due to which blood sodium falls excessively. Blood becomes diluted, and sodium levels drop dangerously.

Due to hyponatremia, a person goes into a nauseous state, indirectly affecting the stomach and leading to stomach pain.

  • Exercise-related transient abdominal pain:

ETAP, or the Exercise-related Transient Abdominal Pain, is used for stomach pain due to constant abdominal movements similar to those in an Abs workout or lower abdomen workout. 

It might feel like a stabbing or stitching pain during a workout that involves continuous motion from an extended position of the abdomen. 

  • Underlying problems:

Living with any gastrointestinal disease or condition can make your symptoms feel worse. This does not mean that you should avoid exercising altogether; however, if the intensity is too high for what’s working in terms of things under control, it may be best to choose less intense forms such as walking when lightweights are more manageable.

Conditions like inflammatory bowel disease and gastroesophageal reflux are underlying conditions that could worsen with heavy exercise. Therefore, you must consult your doctor before doing any hard work out in such situations, or it could complicate your disease.

  • Dehydration:

When we exercise, our bodies create a demand for more fluids. If you are not adequately hydrated, the increased workload can cause discomfort and even trigger nausea in your stomach because it impacts how much blood flows through your body.

To prevent this, athletes need to stay mindful of their drink intake during activity.


Usually, your abs muscles hurt after a heavy and vigorous exercise. Sometimes, it might be worth worrying about, but otherwise, it is usual. Loading any power for a longer duration would cause pain and cramps in that region. But if your abdominal pain doesn’t go on its own, then you can try the following remedies to relieve your stomach hurt after a heavy workout:

  • Try the upward-facing dog pose. It might help in relaxing abs muscles.
  • Hold your breath for approx. 5-10 seconds, and then breath out. It works too.
  • Lay down on your stomach on the floor, and try doing some resting yoga.
  • Drink water frequently after a workout. It might help you out.
  • Perform either cold or heat therapy.
  • Do yoga, as it relieves muscle stress and helps you relax.
  • If the pain continues, take any painkillers.

Even though the pain lasts for several days after this, please consult your doctor, as it might need medical attention immediately.


Many people experience stomach pain when they exercise. The cause of this discomfort can be several things, including irritation from repetitive motion or poor diet choices that lead up to the point where you’re exercising- so make sure your nutrition is on track! Some reported symptoms include nausea and diarrhea with some degree’s variation in intensity depending upon how much effort it took for someone else to finish their last task!


  • Does stomach pain during exercise need medical treatment?

Some people think they only experience pain during or after exercising, but it can also come before a workout. The location and severity of these stomach issues will vary from person to person; some may have dull aches while others get sharp shooting pains in their lower abdomen region – both scenarios being equally frustrating! 

In such scenarios, one needs to seek medical advice as soon as possible if the pain doesn’t go.

  • Why does a person feel nauseous after a workout?

During workouts, blood flow to gastrointestinal organs is reduced to around 75-80% since more blood is supplied to the skin and exercising muscles. This could lead to nausea and vomiting, as the blood needs of the GIT region aren’t fulfilled. Eating near the workout time and before exercise could also lead to a nauseous state.

  • Why do you have an upset stomach after workouts?

When you exercise, your digestive system can stress out and cause symptoms of diarrhea. Sometimes this is due to fluctuating hormones or reduced blood flow, but sometimes it’s because certain types of exercises make food move through our guts faster than usual!

Fewer nutrients are absorbed in the intestines, and looser stools may come from not feeling fully hydrated after working hard during a workout.

  • Should I stop exercising if my stomach hurts?

With all of these great reasons to skip or scale back on exercise, it’s no wonder that many people suffering from diarrhea and throwing up would become dehydrated. If you were active while still experiencing symptoms like this, your dehydration could worsen – not better! 

Therefore, it is better to skip exercise during such circumstances rather than worsen your conditions.
