What does feeling nauseous while exercising warn about?

Feeling nauseous during exercise is more common than you might think. A study published in the journal Przeglad Gastroentrologiczny Gastroenterology Review found that at least 20% of athletes surveyed reported feeling nauseous during exercise, according to the health site Livestrong (USA).

Nausea during exercise occurs for many different reasons.

Dehydration

Dehydration occurs when the body sweats too much, leading to an imbalance of water and electrolytes. Therefore, intense exercise without drinking enough water can easily lead to nausea and even vomiting. In addition, dehydration is also accompanied by other symptoms such as dry tongue, headache, dizziness and flushed skin.

To avoid dehydration, exercisers should drink water frequently during exercise and only drink a little at a time. Drinking too much water will make you feel full and easily vomit when exercising vigorously.

Changes in blood circulation

When you exercise, your heart rate increases, your lungs breathe more deeply, and your muscles contract more forcefully. More blood is directed to your muscles and bones in response to the intensity of the exercise. The more intense the exercise, the more blood flows to your muscles.

This condition causes less blood to flow to the intestines. As a result, it affects digestion because the intestines need a large amount of blood to digest well. Therefore, if you eat a lot and then exercise right away, it will put pressure on the digestive system, which can easily cause nausea.

Accumulation of lactic acid

The concentration of lactic acid in the body will increase when exercising. If lactic acid accumulates too much, exceeding the body's normal tolerance, it will cause muscle pain, cramps and even nausea. To avoid this situation, during the exercise session, the practitioner needs to have necessary rest periods to avoid lactic acid accumulating too much.

Hyponatremia

Endurance exercise, such as running, can cause low blood sodium levels. If sodium falls below 135 millimoles per liter of blood, hyponatremia results.

Common symptoms include vomiting, headaches, and nausea. To avoid this, exercisers should regularly drink water and electrolytes throughout the workout, according to Livestrong .
