Symptoms Of Thyroid NodulesThe thyroid gland, situated in the neck, secretes hormones that regulate growth as well as development. Nodules in the thyroid are nothing but lumps (either fluid-filled or solid) that grows in the thyroid gland.
Not all the nodules that develop in the thyroid cause pain to the individual. Some of them, in fact, remain undetected as they are too small in size. While bigger nodules cause pain in the jaws and the neck region, smaller nodules can only be detected through the medical examination of a physician. Ultrasonography, thyroid function tests and scans are taken to detect these nodules. A very small percentage of the nodules can end up being malignant.
Causes of Thyroid Nodules Formation:
The reasons for the formation of these modules are not very distinct. But, experts believe that people who are exposed to harmful radiation are susceptible to this problem. The other reasons could be lack of sufficient iodine in the body as well as heredity.
Thyroid-related diseases, such as overgrowth of the tissue, inflammation of the thyroid gland, thyroid cancer or multi-nodular goiter, also lead to the formation of nodules.
Symptoms of Thyroid Nodules:
The common symptoms of development of the nodules are:
- Difficulty in swallowing and breathing
- Pain in the neck, jaw and ear region
- Voice huskiness, which does not get cured for a long time
- Enlargement of the thyroid gland (called goiter) -- occurs in severe cases
- Sudden and abnormal loss of weight
- Sudden change in the pattern of heart beat
- Insomnia or disturbed sleep
- Weakening of muscles
- Tickling feeling in the throat
- Dryness of skin
- Mood swings
Visible symptoms of these nodules appear only if they are large. Tiny nodules may not cause harm or even pain to the individual. Formation of multiple nodules can also result in pain.
Most people who develop large nodules sense a sort of lump in the neck region. Difficulty in sleeping and extreme tiredness can occur if the nodules cause secretion of excess hormones. This state is called hyperthyroidism.
These nodules can be cured easily if treatment is taken at the right time. The treatment should begin in the initial stages itself. Cancerous nodules make the voice hoarse and form solid lumps that do not move even when they are touched. Cancerous nodules can also result in the inflammation of lymph nodes. A biopsy is conducted to detect whether the nodules are cancerous.
