Can Exercise Cause Swelling?

Can Exercise Cause Swelling?

An intense workout can make you feel bloated. This sensation could be caused by a pathology called hyponatremia, which appears when sodium levels are reduced in the blood and cells begin to retain water. If you experience symptoms of hyponatremia, such as swelling, dizziness, fatigue, nausea and muscle weakness, contact your doctor.


Swelling is a symptom of dehydration. When your body does not get enough fluids, it will retain fluids and you will notice some swelling. To avoid dehydration during exercise, drink water before, during and after each training session. To manage electrolyte levels and prevent your sodium levels from falling, consider drinking a sports drink instead of water.


Heat can also be a factor in influencing water retention at the end of a training session. When you sweat, you release sodium and water from the body. Sodium reduction and water loss can cause water retention and make you feel bloated at the end of the session. To combat this problem, exercise in climate controlled environments and wear comfortable, breathable clothing.

Excessive fluid intake

Consuming excessive amounts of water during intense exercise sessions may produce hyponatremia. When you drink a lot of water during a marathon or triathlon, the sodium content of your blood can be diluted. According to the American College of Sports Medicine, people who are prone to this pathology are those who sweat less, have less body build and run slower during competitions.


Some medical conditions can cause swelling and this symptom is not always caused by exercise. Other reasons why you may suffer swelling are premenstrual syndrome, gas, constipation and intestinal obstruction. It can also be a side effect of a supplement or medication that you are using.
