Doctor's Notes on Hashimoto's Thyroiditis
Hashimoto's thyroiditis (also termed chronic autoimmune thyroiditis and/or chronic lymphocytic thyroiditis) is a disorder that causes the thyroid gland to underproduce thyroid hormones (hypothyroidism). The symptoms and signs are slowly progressive and may develop over years. Some of the signs and symptoms of hyperthyroidism are numerous and may more or less increase in severity as the disease worsens. Signs and symptoms include at least one or more of the following, such as
- feeling cold,
- mental fogginess,
- dry skin,
- stiffness and aches in muscles and joints,
- prolonged menstrual bleeding,
- weight gain,
- face puffiness,
- thinning and brittle hair and/or hair loss,
- slow heart rate,
- irregular menstrual periods,
- decreased sweating,
- nails are thick and/or brittle,
- decreased reflexes,
- swollen hands and feet,
- cold skin,
- sleepiness, and
- enlargement of the thyroid gland (goiter).
The cause of Hashimoto's thyroiditis is thought by researchers to be a combination of genetic predisposition along with an environmental trigger that starts the autoimmune destruction of the thyroid. The triggers are unknown. Researchers also theorize that heredity, gender, and age play a role in developing this disease. In addition, there are risk factors that are closely associated with the development of Hashimoto's thyroiditis such as female gender (about 10 to 15 times more likely to develop the disease than men), family history, excessive iodine intake, and radiation exposure to the thyroid gland.
What Is the Treatment for Hashimoto's Thyroiditis?
Treatment for the disease includes observation and medications.
- Tests suggest Hashimoto's disease, but the person has no symptoms of the disease.
- Repeated tests over time to see if thyroid hormone levels and/or abnormal antibodies develop
- Synthetic hormone replacement (levothyroxine)
- Repeated tests of levothyroxine to check for therapeutic levels to avoid under and overdosing
In addition, your doctor can discuss the use of certain medicines that may need changing because they alter the absorption of levothyroxine and can caution you on the use of alternative medicines like Armour Thyroid.

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.
Myxedema (Crisis) ComaThe thyroid gland at the front of the neck is responsible for helping to regulate metabolism through secreting hormones. When the gland secretes too little, it can result in the rare but serious myxedema coma. IV fluids and hormone replacement are included in treatment.
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 NodulesThyroid nodules are lumps that are either solid or fluid-filled. Thyroid nodules may be benign or malignant (cancerous). Thyroid nodules may be caused by goiters, Hashimoto's thyroiditis, thyroid cysts, benign thyroid tumors, malignant thyroid tumors, or thyroid cancer. Treatment depends upon the type and cause of the thyroid nodule.
Thyroid ProblemsDiseases of the thyroid gland can lead to hyperthyroidism, hypothyroidism, thyroid nodules, thyroid goiters, or thyroid cancer. Learn about symptoms, causes, and treatment.
