Doctor's Notes on Thyroid Nodules
The thyroid gland in the neck produces thyroid hormone, which is needed for normal growth and metabolism. Lumps called nodules may appear on the thyroid and may be either solid or fluid-filled. Thyroid nodules are more common as people age, and most are benign and not cancerous. A physician may detect a nodule during a physical exam, or they may be found during imaging such as on computed tomography (CT scan), magnetic resonance imaging (MRI), or ultrasound of the front of the neck.
Most of the time, thyroid nodules do not cause symptoms. When they do occur, symptoms of thyroid nodules may include a visible lump on the front of the neck, a rapidly growing lump on the front of the neck, a lump felt in the throat, difficulty swallowing, hoarseness, other enlarged glands or lymph nodes in the neck, and in rare cases, pain.

Must Read Articles:
HyperthyroidismHyperthyroidism refers to a condition in which the thyroid gland produces too much thyroid hormone. Causes of hyperthyroidism include: Graves' disease, thyroid adenoma, thyroid goiter, subacute thyroiditis, and drug-induce hyperthyroidism. Symptoms of hyperthyroidism include irritability, heart palpitations, heat intolerance, weight loss or gain, frequent bowel movements, lower leg edema, infertility, fatigue, and more. Treatment for hyperthyroidism depends on the cause and can include medications or surgery.
HypothyroidismHypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone. Causes of hypothyroidism include: Hashimotot's thyroiditis, subacute thyroiditis, previous thyroid therapy, drug-induced, Pituitary or hypothalamic disease, and iron deficiency. Some common symptoms of hypothyroidism are: fatigue, constipation, weight gain, poor appetite, dry and rough skin, coarse hair, hair loss, edema, depression, and elevated cholesterol levels. Treatment of hypothyroidism is generally with medication.

Thyroid FAQsThe thyroid gland is part of the endocrine (hormone) system. The thyroid gland produces two hormones, thyroxine (T4) and tri-iodothyronine (T3). Diseases of the thyroid gland include: hyperthyroidism, subacute thyroiditis, thyroid cancer, and thyroid nodules. Thyroid medications are used to treat thyroid disorders.
Thyroid MedicationsThyroid medications treat diseases of the thyroid, including hyperthyroidism (such as Graves' disease), hypothyroidism, thyroid disorders in pregnancy, post-partum thyroid disease, thyroid cancer, Hashimoto's thyroiditis, and thyroid nodules. Thyroid medications replace thyroid hormone levels [L-thyroxine (or LT4), L-triiodothyronine (T3)] or suppress growth of thyroid tissue [propylthiouracil (PTU), methimazole], or control symptoms such as beta-blockers and iodide solutions.
Thyroid ProblemsDiseases of the thyroid gland can lead to hyperthyroidism, hypothyroidism, thyroid nodules, thyroid goiters, or thyroid cancer. Symptoms of both hypo- and hyperthyroidism-related conditions include constipation, fatigue, weight gain, cold or heat intolerance, to coma. Treatment depends upon the thyroid condition.
