Thyroid nodules is a very common disease and is also common. There are many reasons for inducing thyroid nodules, and there are many types. The symptoms of each type of thyroid nodule are also different.
thyroid nodules and symptoms and harms
Different types of thyroid nodules have different symptoms:
1. thyroid cyst
Most of them are formed by the degenerative transformation of goiter nodules or adenoma. The cyst contains blood or micro-mixed liquid, has clear boundaries with the surroundings, has a hard texture, and is generally free of tenderness. Nuclear scanning indicates "cold nodules". A few patients are caused by congenital thyroid cyst or residuals of the fourth gill slit.
Nodular toxic goiter
2. Nodular toxic goiter
This disease starts slowly and often occurs in patients with nodular goiter for many years. Most of them are over 40-50 years old. It is more common in women and may be accompanied by symptoms of hyperthyroidism and physical symptoms. However, the symptoms of hyperthyroidism are generally mild, often atypical, and generally do not have invasive epilepsy. During palpation of the thyroid, a smooth round or oval nodule can be palpated with clear boundaries and hard texture. It moves up and down as you swallow. There is no vascular murmur in the thyroid part. Thyroid function examination showed an elevated thyroid hormone in the blood. The nuclide scan showed " heat nodule ".
Inflammatory thyroid nodules
3. Inflammatory thyroid nodules
is divided into two categories: infectious and non-infectious. The former is mainly subacute thyroiditis caused by viral infection, and other infections are rare. In clinical practice, methyleneitis is not only accompanied by thyroid nodules, but also with fever and local thyroid pain. The size of the nodules depends on the range of the lesion and has a tough texture. The latter is mainly caused by autoimmune thyroiditis, which is more common in middle-aged and young women. The patients have fewer conscious symptoms. Multiple or single nodules can be palpated during examination, with a hard texture and less tenderness. During thyroid function examination, it is often strongly positive for thyroglobulin antibody and thyroid microsomal antibodies.
4. Nodular goiter
Most common in middle-aged women. When the thyroid hormone is relatively insufficient in the body, the pituitary secretes TSH. Under the long-term stimulation of this increased TSH, the thyroid gland will increase in thyroid unevenness and nodule-like change after repeated or continuous hyperplasia. There may be bleeding, cystic changes and calcification in the nodules. The size of the nodules can range from several millimeters to several centimeters. The main clinical manifestations are goiter. Multiple nodules of varying sizes can be palpated during palpation. The texture of the nodules is mostly moderately hard. A few patients can only palpate a single nodule, but multiple nodules are often found during thyroid imaging or surgery. The patient has few clinical symptoms, usually only feels of pre-neck discomfort, and most thyroid function tests are normal.
5. Thyroid tumor
includes benign thyroid tumors, thyroid cancer and metastatic cancer.
What are the harms of thyroid nodules:
In recent years, as more and more people suffer from thyroid disease , what is thyroid nodules. Thyroid nodules are more common in middle-aged women, and most of them are seen in multiple nodules. Generally, thyroid nodules can be divided into thyroid nodules and multiple nodules. Nodules on the thyroid gland may be thyroid cancer, or other causes such as thyroid tumors, nodular goiter, and are collectively called thyroid nodules before their properties are clarified.
1. Compressing the esophagus: rare. Only , goiter behind the sternum, may compress the esophagus, causing discomfort during swallowing, but will not cause obstruction symptoms.
2. The impact of thyroid nodules on daily life: When you suffer from thyroid nodules, you will feel upset and easily angry. You speak very loudly and have a thick breathing sound. You like to lose your temper and are very prone to quarrel with them, so it is very harmful to others and family.
3. Compressing the deep neck vein: it can cause difficulty in blood reflux in the head and neck. This condition is more common in large goiters located in the upper mouth of the chest, especially the posterior sternum goiters. The patient's face was bluish-purple swelling, and there was also obvious dilation of the superficial veins on the neck and chest.
4. The impact of thyroid nodules on labor and work efficiency: Patients with thyroid nodules will feel anxious and short of breath, and they will not be able to sleep and dream, so their efficiency will be very low at work, and they will even lose the ability to work. Thyroid nodules can cause eye ejaculation, eyelids cannot be closed or eye diplopia, and in severe cases, it can also lead to insomnia in the patient.
5. Compressing the recurrent laryngeal nerve: It can cause vocal cord paralysis (mostly one side), and the patient's voice is hoarse. Compressing the sympathetic nerve chain of the neck can cause Horner syndrome , which is extremely rare. Compressing the large veins in the deep neck can cause difficulty in blood reflux in the head and neck. Thyroid nodules are divided into benign and malignant. Benign mainly includes nodular goiter, thyroid adenoma , etc.; malignant thyroid nodules are thyroid cancer.
6. Compression of the trachea: more common. Compressing from one side, the trachea is displaced or bent to the other side; compressing from both sides, the trachea is narrow and breathing is difficult, especially when goiter is behind the sternum. Long-term pressure on the tracheal wall can cause softening of the trachea and suffocation.
