Thyroid Dysfunction: Symptoms, Diagnosis, and Treatment Options

Hypothyroidism?

Hello Dr.
Yang: Initially, during a physical examination, it was found that the right side of my thyroid was enlarged, but there were no visible abnormalities, and there is no family history of thyroid disease.
I have a constitution that makes it difficult for me to gain weight, and I often experience insomnia, palpitations, and hand tremors, which I have always suspected were caused by excessive coffee consumption—about one cup (approximately 250ml) a day.
I also wondered if it was due to high stress.
After learning about the enlargement of the right thyroid during the examination, I began to suspect whether the aforementioned symptoms were due to hyperthyroidism.
Later, my insomnia severely affected my life, so I underwent a thyroid ultrasound, which revealed that there was no thyroid on the left side at all.
The doctor mentioned that this is a congenital condition of having only half a thyroid, which theoretically should lead to hypothyroidism.
Currently, I may have mild edema, fatigue, and hoarseness—these are non-specific symptoms.
However, there is no delay or deficiency in my intelligence, thinking, reaction, or behavior; I am currently in graduate school.
My T3, T4, and TSH levels are all normal.
In the end, the doctor prescribed me Eltroxin, knowing that this is a medication for treating hypothyroidism.
At that moment, I asked the doctor if I could avoid taking it because I am already prone to anxiety, have a light body weight, palpitations, and insomnia, and I am afraid it would add to my physical burden.
However, the doctor said, "If you don’t take it, it will swell!" I would like to ask Dr.
Yang: 1.
What is the pathological term for congenital absence of part of the thyroid? 2.
How can I alleviate symptoms of insomnia, anxiety, and palpitations? 3.
If I start taking Eltroxin and experience severe side effects that affect my daily life, would stopping the medication on my own potentially cause the right thyroid to enlarge?

Your symptoms are likely unrelated to the thyroid.
If they are causing distress, medication may be considered to alleviate the symptoms.
Using thyroid hormone to reduce the size of the right thyroid lobe may not have a significant effect.
If thyroid function is normal and the right thyroid lobe is not significantly enlarged, the use of thyroid hormone may not be necessary.

Understanding thyroid dysfunction is crucial for managing symptoms and ensuring overall health. Based on your description, it seems you have been diagnosed with a condition related to your thyroid gland, particularly concerning the asymmetry of your thyroid and the presence of symptoms like insomnia, palpitations, and tremors. Let’s address your questions and provide some insights into managing your condition.

1. Congenital Absence of Part of the Thyroid Gland: The condition you are referring to, where there is a congenital absence of part of the thyroid gland, is known as "thyroid agenesis" or "thyroid hypoplasia." This condition can lead to hypothyroidism, especially if the remaining thyroid tissue is not sufficient to meet the body's needs. It is essential to monitor thyroid function regularly, as the absence of a complete gland can lead to fluctuations in hormone levels.

2. Managing Symptoms of Insomnia, Anxiety, and Palpitations: To alleviate symptoms such as insomnia, anxiety, and palpitations, consider the following strategies:
- Lifestyle Modifications: Incorporate relaxation techniques such as yoga, meditation, or deep-breathing exercises into your daily routine. These practices can help reduce stress and improve sleep quality.

- Dietary Adjustments: Maintain a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Avoid stimulants like caffeine, especially in the afternoon and evening, as they can exacerbate anxiety and disrupt sleep.

- Regular Exercise: Engage in regular physical activity, which can help reduce anxiety and improve sleep. Aim for at least 30 minutes of moderate exercise most days of the week.

- Sleep Hygiene: Establish a regular sleep schedule, create a comfortable sleep environment, and limit screen time before bed to improve sleep quality.

3. Concerns About Eltroxin (Levothyroxine) and Side Effects: Eltroxin is a synthetic form of thyroxine (T4) used to treat hypothyroidism. If your doctor has prescribed it, it is likely because they believe your thyroid function may not be adequate. Stopping the medication without consulting your doctor can lead to a worsening of your symptoms and potentially cause the remaining thyroid tissue to become overactive, leading to further complications. If you experience side effects, it is crucial to communicate with your healthcare provider. They may adjust your dosage or explore alternative treatments to minimize side effects while ensuring adequate thyroid hormone levels.

In conclusion, managing thyroid dysfunction requires a comprehensive approach that includes regular monitoring of thyroid hormone levels, lifestyle modifications, and adherence to prescribed treatments. It is essential to maintain open communication with your healthcare provider to address any concerns and adjust your treatment plan as necessary. If you have further questions or if your symptoms persist, consider seeking a second opinion or consulting an endocrinologist who specializes in thyroid disorders.
