Mitral Valve Prolapse: Weight Loss and Thyroid Concerns

I would like to ask the doctor a question?

Dear Dr.
Yang,
I currently have mitral valve prolapse, but around April and May of this year, I suddenly lost weight and dropped to about 35 kilograms, whereas I was around 37 kilograms before.
I am 163 centimeters tall, so there is quite a discrepancy in my weight.
I had my thyroid checked two or three years ago, and there were no abnormalities at that time.
I am more concerned about whether the previous normal results mean I will not have any issues in the future.
I get very anxious easily; I always try to calm myself down, but it often backfires.
I am unsure how to handle it.
The cardiologist is aware of my anxiety and advises me not to be too invested in my work, but how can I not be engaged in my work? Dr.
Yang, if I want to know whether I have thyroid issues now, do I necessarily need to have a blood test? I am very afraid of needles (for example, injections and blood draws); I just do not like anything related to needles.
Are there any other methods to check for thyroid function? I currently have some symptoms, but I am missing two or three others.
I also experience palpitations, chest tightness, and difficulty breathing, and sometimes I have asthma (though this situation is currently manageable).
Thank you.

Symptoms of hyperthyroidism include palpitations, tremors, sweating, anxiety, and weight loss.
In fact, the symptoms of hyperthyroidism are quite similar to those caused by anxiety.
However, the severity of symptoms caused by hyperthyroidism is usually greater than that caused by anxiety.
To confirm the diagnosis, blood tests are necessary.
If there is a presence of goiter or a family history of thyroid disease, the likelihood of developing hyperthyroidism increases.

More Info

Mitral Valve Prolapse (MVP) is a condition where the mitral valve does not close properly, which can lead to various symptoms, including palpitations, chest discomfort, and in some cases, anxiety. Your concern about significant weight loss and potential thyroid issues is valid, as both conditions can be interrelated.

Firstly, the sudden weight loss you experienced, dropping to 35 kg from 37 kg at a height of 163 cm, is concerning. This represents a significant change in your body weight and could indicate an underlying health issue. Weight loss can be attributed to various factors, including hyperthyroidism, which is a condition where the thyroid gland is overactive and produces excess thyroid hormones. Symptoms of hyperthyroidism can include increased heart rate, anxiety, weight loss, and heat intolerance. Given that you have a history of thyroid checks that were normal, it is essential to understand that thyroid function can change over time. Therefore, just because previous tests were normal does not guarantee that future tests will yield the same results.

To assess your thyroid function, a blood test measuring Thyroid Stimulating Hormone (TSH) and free T4 levels is the standard approach. While I understand your apprehension about needles and blood tests, this is the most reliable method to evaluate thyroid function. Unfortunately, there are no non-invasive alternatives that can provide the same level of accuracy. Some imaging tests, like a thyroid ultrasound, can help assess the structure of the thyroid gland, but they do not measure hormone levels.

Your symptoms of palpitations, chest tightness, and difficulty breathing can also be linked to anxiety, which you mentioned is a significant concern for you. Anxiety can exacerbate physical symptoms, leading to a cycle of fear and discomfort. It is crucial to address both your physical and mental health. Techniques such as cognitive-behavioral therapy (CBT), mindfulness, and relaxation exercises can be beneficial in managing anxiety. Additionally, discussing your symptoms with a healthcare provider can help tailor a treatment plan that addresses both your MVP and anxiety.

If your symptoms persist or worsen, it is essential to follow up with your cardiologist or primary care physician. They can provide a comprehensive evaluation, including a physical examination and possibly additional tests, to rule out any serious conditions. If you are hesitant about blood tests, express this to your healthcare provider; they may be able to offer support or alternative methods to help you cope with your anxiety regarding needles.

In summary, while your history of MVP and anxiety may contribute to your symptoms, the significant weight loss warrants further investigation into your thyroid function and overall health. Regular follow-ups with your healthcare provider, open communication about your concerns, and addressing anxiety through appropriate channels can help you manage your health more effectively.
