Do you get a stomach ache after working out? While it’s common, it’s still really uncomfortable and annoying. There are many reasons why you get nauseous after exercising as well as ways to avoid the terrible feeling in the future. Here’s why you get a stomach ache after working out and how to avoid it from happening.


Excessive amounts of anti-inflammatory medicines like ibuprofen or naproxen can cause nausea. If you’re feeling achy before your workout, it’s tempting to take meds, but never take more than the recommended amount of the box or what your doctor prescribed. Instead, try and take anti-inflammatories post-workout.

Intensity Level

While exercise-induced nausea can happen at any speed and any intensity, high-intensity exercise can increase your chances of nausea during workouts. If you’re feeling nauseous while working out, reduce your speed or resistance until you’re feeling better.

Fitness Level

Contrary to popular belief, nausea can occur at any fitness level, beginners aren’t more prone to it if they push themselves too hard.


Dehydration can exacerbate GI distress and gut immobility, leading to stomach aches. So, drink more water throughout the day to stay hydrated.


Eating large meals and then exercising can lead to stomach aches and so does skipping meals and not eating balanced ones. You don’t want to be too full or hungry when working out. Try eating a small snack 30 minutes to an hour before exercising.
