Thyroid Nodule: Symptom,causes,diagnosis and treatment.
What is Thyroid Nodule?
Symptoms of Thyroid nodule.-
Thyroid nodules most often do not cause symptoms.
But if the nodule gets large enough, you may develop:-
- Thyroid nodules are abnormal growths of tissue in the thyroid gland that are most often benign—but may be cancerous (a very rare condition ) in some people.
- Some people have one nodule while others have many.
- Thyroid nodules may be solid tissue or filled with blood or other fluid.
- Thyroid nodules are quite common, with as many as half of all people having at least one nodule by the age of 60.
- Sometimes it looks like a lump over a thyroid gland.
Symptoms of Thyroid nodule.-
Thyroid nodules most often do not cause symptoms.
But if the nodule gets large enough, you may develop:-
- pain at the base of your neck
- swallowing difficulties
- breathing difficulties
- hoarse voice
Other symptoms are similar to hypo and hyperthyroid diseases-
- Anxiety
- Irritability or moodiness
- Nervousness, hyperactivity
- Sweating or sensitivity to high temperatures
- Rapid heart rate
- Hand trembling (shaking)
- Hair loss
- Frequent bowel movements or diarrhea
- Weight loss
- Missed or light menstrual periods.
What causes Thyroid Nodule?
The majority of thyroid nodules are caused by an overgrowth of normal thyroid tissue. The cause of this overgrowth is usually unknown, but there is a strong genetic basis.
In rare cases, thyroid nodules are associated with:
- Hashimoto’s disease, an autoimmune disease that leads to hypothyroidism
- thyroiditis, or chronic inflammation of your thyroid gland.
- thyroid cancer.
- iodine deficiency.
Iodine deficiency is rare in the United States due to the widespread use of iodized salt and iodine-containing multivitamins.
How thyroid nodule diagnosed?
Thyroid nodules commonly find during clinical examination by a doctor of your thyroid gland.
The doctor may ask your family history. because there is a strong genetic basis.
They will advice one or more of the following tests to diagnose and assess your nodule:-
1.Thyroid ultrasound, to examine the structure and size of the nodule
2. Thyroid scan, to learn if the nodule is hot, warm, or cold. (in overactive thyroid)
3.Fine needle aspiration(FNAC) to collect a sample of the nodule for testing in a laboratory
Treatment of Thyroid Nodule:-
1. Most of the thyroid nodule is not cancerous.
2. The doctor will suggest a treatment on the basis of size and type of thyroid nodule.
3. If thyroid nodule continuous to grow and causes symptom like difficulty in breathing and swallowing then the doctor will advise you to go for planned surgery.
4. Surgical removal is the final step of the treatment.
5. If your nodule is hot or overproducing thyroid hormones, your endocrinologist will probably use radioactive iodine or surgery to eliminate the nodule.
6.Nodules that make too much of the thyroid hormones T3 and T4 may be treated with radioactive iodine or alcohol ablation. Radioactive iodine is given as a pill and causes the thyroid gland to shrink and make less thyroid hormone.

CaliforniaThyroidCenter The thyroid gland is a small butterfly-shaped gland located in the front of the neck. It is divided into two lobes, connected by a narrow strip of thyroid tissue known as the isthmus. Structurally, the thyroid gland is organized in small follicles that store the thyroid hormones. Functionally, the thyroid gland is going to produce three hormones, triiodothyronine (T3), tetraiodothyronine (T4), and calcitonin. T3 and T4 play a crucial role in controlling our metabolism and they are also important for growth and brain development during childhood. On the other hand, calcitonin is involved in regulating calcium and bone metabolism.
