Discomfort in the stomach during exercise?


Hello Dr.
Chen, I have recently been practicing freestyle turns in the swimming pool, and whenever I do it frequently, I start to feel nauseous and want to vomit.
My stomach also feels uncomfortable, and this discomfort lasts for several days.
Could you please explain why this is happening?

It may be gastroesophageal reflux disease (GERD) or gastritis.
Start by monitoring your diet and take medication for control.

More Info


Feeling nauseous and uncomfortable while swimming, especially after performing repetitive movements like freestyle flips, can be attributed to several factors. Understanding these factors can help you manage your symptoms and enjoy your swimming sessions more comfortably.

1. Physical Exertion: Swimming is a physically demanding activity that engages multiple muscle groups. If you're not accustomed to the intensity of your workouts, you may experience nausea due to overexertion. As your body works harder, it diverts blood flow from the stomach to the muscles, which can lead to gastrointestinal discomfort.

2. Breathing Technique: Proper breathing is crucial in swimming. If you're holding your breath or not exhaling fully while performing flips, it can lead to a buildup of carbon dioxide in your system, causing dizziness and nausea. Ensure that you are breathing rhythmically and deeply, especially during flips.

3. Water Temperature: The temperature of the pool water can also affect how you feel while swimming. If the water is too cold or too warm, it can lead to discomfort and nausea. Ideally, the water should be at a comfortable temperature that allows you to swim without feeling chilled or overheated.

4. Hydration and Nutrition: Dehydration can lead to nausea, especially during physical activity. Make sure you are well-hydrated before and during your swim. Additionally, consider what you eat before swimming; heavy or greasy meals can cause discomfort. A light snack that includes carbohydrates and protein may be more suitable.

5. Motion Sickness: Some individuals may experience motion sickness while swimming, particularly during flips or turns. This can occur due to the rapid changes in position and orientation in the water. If you are prone to motion sickness, you might want to take it slow and gradually increase the intensity of your swimming practice.

6. Gastroesophageal Reflux Disease (GERD): If you have a history of acid reflux or GERD, the physical activity of swimming, especially with flips, can exacerbate these symptoms. The pressure from the water and the position of your body can cause stomach acid to flow back into the esophagus, leading to nausea and discomfort.

7. Anxiety or Stress: Sometimes, the discomfort can stem from psychological factors. If you feel anxious or stressed while swimming, it can manifest physically as nausea. Consider practicing relaxation techniques or mindfulness before your swim to help alleviate anxiety.


Recommendations:
- Warm-Up: Always start with a proper warm-up to prepare your body for the physical activity.

- Breathing Practice: Focus on your breathing technique. Practice exhaling underwater and inhaling when you turn your head to the side.

- Hydration: Drink water before and after swimming to stay hydrated.

- Nutrition: Eat a light snack before swimming, avoiding heavy meals.

- Pace Yourself: Gradually increase the intensity of your swimming sessions to allow your body to adapt.

- Consult a Professional: If the nausea persists, consider consulting a healthcare professional to rule out any underlying medical conditions, such as GERD or other gastrointestinal issues.

In summary, feeling nauseous while swimming can be due to a combination of physical exertion, breathing techniques, hydration, and even psychological factors. By addressing these areas, you can improve your swimming experience and reduce discomfort. If symptoms continue, seeking medical advice is essential to ensure there are no underlying health concerns.
