the Link Between Acute Tonsillitis and Worsening Hyperthyroidism

Symptoms of hyperthyroidism significantly worsened after acute tonsillitis?

Hello, Doctor Gao.
I have a few questions to ask you.
Last week, I visited a large hospital due to acute tonsillitis.
While examining my neck, I noticed some swelling, so I asked the doctor to order a blood test.
The results were TSH: 0.4, T3: 494.15, and T4: 2.81.
The doctor diagnosed me with hyperthyroidism, and I started taking Methimazole 5 mg three times a day.
Since the onset of acute tonsillitis and the discovery of "hyperthyroidism," I have been on Methimazole for 5 days.
In just 7 days, the symptoms of hyperthyroidism have become increasingly pronounced, with the following symptoms: 1.
Decreased strength in my hands and feet; sometimes my hands suddenly feel weak, and my legs tremble, making it difficult to run like before.
2.
Blurred vision (intermittent).
3.
Increased fatigue.
4.
Increased frequency of bowel movements.
5.
Irritability and impatience.
6.
Decreased memory.
7.
Increased hunger and weakness in my limbs, which is particularly troubling.

Could you please explain why there has been such a sudden change? Would you recommend using traditional Chinese medicine for body conditioning? Is hyperthyroidism treatable? Thank you for taking the time to answer my questions, and I appreciate your hard work!

Hello, thank you for your question.
I am an allergist and immunologist, so my experience with thyroid dysfunction (endocrinology) is limited.
I recommend that you consult with an endocrinologist regarding your concerns.
As for traditional Chinese medicine, it is advisable to see a licensed practitioner who has close communication with Western medicine doctors to avoid exacerbating thyroid function issues due to herbal treatments.
You can also ask the endocrinologist for their opinion on this matter.
Lastly, whether hyperthyroidism can be cured depends on the specific type of hyperthyroidism you have.
Some patients may be able to discontinue their hyperthyroid medications after a period of treatment.
Best regards from the Allergy, Immunology, and Rheumatology Department of Changhua Hospital, Ministry of Health and Welfare.

Hello! Thank you for your questions regarding the relationship between acute tonsillitis and worsening hyperthyroidism. It’s important to understand that while these two conditions may seem unrelated, they can indeed influence each other in certain circumstances.

Acute tonsillitis is an inflammation of the tonsils, often caused by viral or bacterial infections. Symptoms typically include sore throat, difficulty swallowing, fever, and swollen lymph nodes. On the other hand, hyperthyroidism is a condition where the thyroid gland produces excessive amounts of thyroid hormones, leading to symptoms such as weight loss, increased appetite, anxiety, tremors, and fatigue.

In your case, the acute tonsillitis may have triggered or exacerbated your underlying hyperthyroidism. Stress from an acute illness can sometimes lead to fluctuations in thyroid hormone levels. The body’s response to infection can cause an increase in the production of thyroid hormones, which may explain the sudden worsening of your hyperthyroid symptoms after the onset of tonsillitis.

Your lab results indicate low TSH (Thyroid Stimulating Hormone) and elevated T3 and T4 levels, which are characteristic of hyperthyroidism. Methimazole, which you have started taking, is an antithyroid medication that works by inhibiting the production of thyroid hormones. However, it may take some time for the medication to stabilize your hormone levels, and during this period, you may experience fluctuations in symptoms.

The symptoms you are experiencing, such as muscle weakness, fatigue, mood changes, and increased bowel movements, are indeed common in hyperthyroidism. The fact that you are feeling weaker and more fatigued could be due to the increased metabolic rate caused by excess thyroid hormones. Additionally, the stress of being ill with tonsillitis could further exacerbate these symptoms.

As for your question about incorporating traditional Chinese medicine (TCM) for body regulation, it can be beneficial for some individuals. TCM approaches often focus on balancing the body's energy (Qi) and may help alleviate some symptoms. However, it is crucial to consult with a healthcare provider who understands both Western and Eastern medicine to ensure that any additional treatments do not interfere with your current medication.

Hyperthyroidism is generally treatable, and many patients can achieve good control of their symptoms with appropriate treatment. Options include antithyroid medications like Methimazole, radioactive iodine therapy, and sometimes surgery. The choice of treatment depends on various factors, including the severity of the condition, the presence of any underlying health issues, and patient preference.

In summary, the acute tonsillitis may have contributed to the worsening of your hyperthyroidism symptoms due to stress and the body’s response to infection. It is essential to continue monitoring your thyroid levels and symptoms closely with your healthcare provider. If you have concerns about your treatment or symptoms, do not hesitate to reach out to your doctor for further evaluation and guidance. Your health and well-being are paramount, and with the right approach, you can manage your hyperthyroidism effectively. Thank you for your inquiry, and I wish you a smooth recovery!
