Concerns about exercise in hypothyroidism?


Hello, Doctor.
I apologize for bothering you, but I would like to ask a question.
Last week, I discovered a lump in my neck, and after visiting the clinic yesterday, I was diagnosed with hypothyroidism.
The physician mentioned that it is severe hypothyroidism, and I started taking Levothyroxine yesterday.
In addition to the recent diagnosis of hypothyroidism, I also have mild mitral valve prolapse, and I have been exercising less during the summer.
However, starting next Monday, I have some team practices, and I would like to know if it is suitable for me to exercise under these circumstances.
The team practices include some intense activities with a lot of running and jumping, which can leave me breathless.
I am a bit concerned that my heart, which has become accustomed to a slower rate, might not handle the exertion well.
Therefore, I would like to ask if it is advisable to exercise just three to four days after starting Levothyroxine.
Thank you for taking the time to respond, and I appreciate your help!

Hello, it is recommended to avoid intense exercise in the initial stages to prevent overexertion.
Once the medication stabilizes, you can gradually increase the intensity of your workouts.
However, it is still advisable not to push yourself too hard.
Thank you for your question.

When it comes to exercising with hypothyroidism, particularly after a recent diagnosis and starting medication like Levothyroxine (昂特欣), there are several important considerations to keep in mind. Hypothyroidism can significantly affect your energy levels, metabolism, and overall physical performance, so it’s crucial to approach exercise with caution.

Firstly, it’s essential to understand that hypothyroidism can lead to fatigue, muscle weakness, and a general decrease in stamina. These symptoms can make it challenging to engage in physical activities, especially those that are vigorous or require a lot of energy, such as team sports or high-intensity workouts. Given that you have also been diagnosed with mild mitral valve prolapse, which can sometimes cause palpitations or irregular heartbeats, it’s wise to be particularly attentive to how your body responds to exercise.

Starting a new medication like Levothyroxine can take some time to stabilize your thyroid hormone levels. Typically, it may take several weeks to notice significant improvements in your energy levels and overall well-being. Therefore, while it’s understandable that you want to participate in team practices, it might be beneficial to ease into your exercise routine rather than jumping into intense activities right away.

Here are some recommendations for exercising with hypothyroidism:
1. Start Slowly: Begin with low to moderate-intensity exercises. Activities like walking, gentle cycling, or swimming can be excellent choices. These types of exercises can help you gauge your energy levels without overwhelming your body.

2. Listen to Your Body: Pay close attention to how you feel during and after exercise. If you experience excessive fatigue, shortness of breath, or any unusual symptoms, it’s important to stop and rest. Your body is adjusting to the new medication, and pushing too hard can lead to setbacks.

3. Stay Hydrated: Dehydration can exacerbate fatigue and other symptoms. Make sure to drink plenty of water before, during, and after your workouts.

4. Consult Your Doctor: Before starting any new exercise regimen, especially after a recent diagnosis, it’s crucial to discuss your plans with your healthcare provider. They can provide personalized advice based on your specific health status and any other conditions you may have.

5. Monitor Your Heart Rate: Given your history of mitral valve prolapse, it may be helpful to monitor your heart rate during exercise. If you notice any irregularities or if your heart rate becomes excessively elevated, it’s best to stop and consult your doctor.

6. Consider a Gradual Increase: Once you feel more comfortable and your energy levels improve, you can gradually increase the intensity and duration of your workouts. This gradual approach can help prevent overexertion and allow your body to adapt.

7. Incorporate Rest Days: Rest is just as important as exercise, especially when your body is adjusting to new medication. Make sure to include rest days in your routine to allow for recovery.

In summary, while it is possible to engage in exercise after starting treatment for hypothyroidism, it’s important to do so thoughtfully and gradually. Listen to your body, consult with your healthcare provider, and prioritize your health and safety as you navigate this new chapter. With time and the right approach, you can find a balance that allows you to enjoy physical activity while managing your condition effectively.
