Thyroid cysts generally do not have any clinical symptoms, but if untreated and continuously growing, there is a risk of hemorrhage within the cyst. Therefore, when a thyroid cyst becomes painful, it may be due to excessive internal pressure and bleeding inside the cyst, causing pain. At this point, it is necessary to go to the hospital emergency department for a comprehensive thyroid ultrasound to observe the size of the cyst, and to provide emergency surgical treatment or local puncture to aspirate the blood and relieve pain.

Do thyroid cysts require a special diet?

Thyroid cysts refer to fluid-containing sacs that appear in the thyroid gland. Generally, these cysts do not become malignant, and they do not present any clinical symptoms, nor do they cause hyperthyroidism. If the cyst is particularly large and compresses the local thyroid tissue, it generally does not lead to hypothyroidism. Therefore, there is generally no need for a special diet for thyroid cysts. However, some scholars believe that the formation of thyroid cysts is related to iodine deficiency, or they can also occur in areas with high iodine content. Hence, it is advisable to avoid consuming foods with particularly high iodine content.

Can people with thyroid cysts eat seaweed?

Thyroid cysts generally do not show any symptoms clinically and are mostly benign. They are usually solitary, but occasionally multiple cysts could be present. Currently, the exact cause of thyroid cysts is not completely understood. Some scholars believe that the formation of thyroid cysts is related to iodine deficiency. Others suggest that in areas with a high incidence of thyroid cysts, the iodine content is also relatively high, indicating that both exceptionally low or high levels of iodine could potentially be a cause of thyroid cysts. Seaweed is a food high in iodine. Eating seaweed occasionally should not have a significant impact, but consuming seaweed daily could lead to excessive iodine levels in the body, which is not advisable during periods of thyroid cyst affliction.

Are thyroid cysts dangerous?

Generally speaking, thyroid cysts are benign lesions and are not dangerous. First, let's understand what thyroid cysts are. A thyroid cyst is a fluid-containing cystic formation found in the thyroid gland. Typically, the lump is round, smooth, painless, or may cause slight pain, and can move up and down with swallowing. Most cysts are solitary nodules, and it is less common to find multiple nodules. Additionally, if the cyst is large or if there is bleeding within the cyst, it can cause symptoms of compression such as pain, difficulty swallowing, difficulty breathing, and hoarseness. We know that about 10% of cystic nodules are malignant, hence, it is important to understand the nature of a thyroid cyst. If it is malignant, surgical removal is necessary. Furthermore, if the nodular cyst is large and causes compression symptoms, surgery is also required. However, most are benign lesions, and thyroid function is within the normal range, so no special treatment is needed, just follow-up observation. Therefore, whether thyroid cysts are dangerous depends on the circumstances.

How should thyroid cysts be treated?

Thyroid cysts refer to fluid-containing sac-like formations found in the thyroid gland. For their treatment, thyroid cysts are a type of benign tumor of the thyroid. In imaging studies, if the nodule's diameter is less than one centimeter, it usually presents no clinical symptoms or signs. Regular follow-ups with thyroid ultrasonography and thyroid function tests are advised. If there is no trend of enlargement, continued observation without surgical intervention can be appropriate. However, if the nodule's diameter is greater than one centimeter, or if it is located on the surface of the thyroid, the local skin may show a protrusion or bulge, and the cyst may continue to grow, pressing on the trachea or even the esophagus, causing symptoms such as chest tightness, difficulty breathing, a feeling of swallowing, and obstruction. It is important to seek medical attention in a timely manner, undergo a fine needle aspiration biopsy if necessary, and surgical treatment may be required if needed.
