Can Thyroid Enlargement Cause Nausea? Symptoms and Treatments

Can the thyroid gland cause nausea?

Hello, I would like to ask if an enlarged thyroid can cause a feeling of nausea? I often feel nauseous after meals to the point where I wish I could remove it to feel better, and touching the area of the thyroid makes me uncomfortable, or even pressure from my clothing collar causes discomfort.
If it is just chronic inflammation, can it be surgically removed, or would medication suffice? Also, does taking thyroid medication affect the menstrual cycle?

Dr. Yang Hongzhi reply Internal Medicine

Thyroid enlargement can sometimes cause patients to feel a sensation of neck pressure.
Generally, medication is effective.
If there are significant compressive symptoms (such as tracheal compression), surgery may be recommended for the patient.

More Info

Thyroid enlargement, also known as goiter, can indeed lead to various symptoms, including discomfort and nausea. The thyroid gland is located in the neck, and when it becomes enlarged, it can exert pressure on surrounding structures, including the esophagus and trachea. This pressure can lead to sensations of fullness, difficulty swallowing, or even nausea, particularly after meals.
In your case, the nausea you experience after eating could be related to the pressure exerted by the enlarged thyroid on the esophagus, which may cause a feeling of discomfort or the urge to vomit. Additionally, if the thyroid is inflamed or if there are nodules present, this could further contribute to your symptoms. It’s important to note that while thyroid enlargement can cause nausea, other gastrointestinal issues could also be at play, so a thorough evaluation by a healthcare professional is recommended.

Regarding treatment options, if the thyroid enlargement is due to chronic inflammation (such as in Hashimoto's thyroiditis) and is not causing significant symptoms or complications, doctors may recommend monitoring the condition rather than immediate surgical intervention. However, if the goiter is large enough to cause discomfort, difficulty swallowing, or other significant symptoms, surgical removal of part or all of the thyroid gland (thyroidectomy) may be considered.
Medications for thyroid conditions, such as levothyroxine for hypothyroidism or antithyroid medications for hyperthyroidism, typically do not directly affect the menstrual cycle. However, hormonal fluctuations can sometimes be influenced by thyroid hormone levels, so it’s essential to discuss any changes in your menstrual cycle with your healthcare provider.
In summary, thyroid enlargement can indeed cause nausea due to pressure on surrounding structures. If your symptoms persist or worsen, it’s crucial to consult with an endocrinologist or a healthcare provider specializing in thyroid disorders. They can perform appropriate tests, such as blood tests for thyroid function and imaging studies, to determine the underlying cause of your symptoms and recommend the best course of action, whether it be medication, monitoring, or surgical intervention.
