What is Hashimoto's thyroiditis?
Thyroiditis is when your thyroid gland becomes irritated. Hashimoto’s thyroiditis is the most common type of this health problem. It is an autoimmune disease. It occurs when your body makes antibodies that attack the cells in your thyroid. The thyroid gland becomes overrun with white blood cells and becomes scarred. This makes the gland feel firm and rubbery. The thyroid then can’t make enough of the thyroid hormone. Many people with this problem have an underactive thyroid gland. That’s also known as hypothyroidism. They have to take medicine to keep their thyroid hormone levels normal.
What is the cause of Hashimoto’s thyroiditis?
Hashimoto’s thyroiditis is an autoimmune disorder. Normally, your immune system protects your body by attacking bacteria and viruses. But with this disease, your immune system attacks your thyroid gland by mistake. Your thyroid then can’t make enough thyroid hormone, so your body can’t work as well.
Who is at risk for Hashimoto’s thyroiditis?
Things that may make it more likely to you for to get Hashimoto’s thyroiditis are:
Being a woman. Women are about 8 times more likely to have the disease. Hashimoto's thyroiditis sometimes begins during pregnancy. The condition may get better in some women during pregnancy. But then it returns after delivery.
Being middle age. Most cases happen between ages 40 and 60. But it has been seen in younger people.
Having a family member with the disease (heredity). The disease tends to run in families. But no gene has been found that carries it.
Having other autoimmune diseases. These health problems raise a person’s risk. Some examples are rheumatoid arthritis and type 1 diabetes. Having this type of thyroiditis puts you at higher risk for other autoimmune illnesses.
What are the symptoms of Hashimoto's thyroiditis?
Each person’s symptoms may vary. Symptoms may include:
This is an enlargement of your thyroid gland. It causes a bulge on your neck. It is not cancer. But it can cause problems such as pain or trouble with swallowing, breathing, or speaking.
When your thyroid doesn’t make enough thyroid hormone, it can cause these symptoms:
When the thyroid is attacked by antibodies, it may at first make more thyroid hormone. This is called Hashitoxicosis. It does not happen to everyone. But it can cause these symptoms:
These symptoms may look like other health problems. Always see your healthcare provider for a diagnosis.
How is Hashimoto's thyroiditis diagnosed?
Your healthcare provider will ask about your health history and give you a physical exam. You will also have blood tests. These can measure your thyroid hormone levels and check for some antibodies to proteins in the thyroid.
How is Hashimoto's thyroiditis treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
You will not need treatment if your thyroid hormone levels are normal. But Hashimoto's thyroiditis can cause an underactive thyroid gland. If so, it can be treated with medicine. The medicine replaces lost thyroid hormone. That should stop your symptoms. It can also ease a goiter if you have one. A goiter can cause problems such as pain or trouble swallowing, breathing, or speaking. If these symptoms don’t get better, you may need surgery to remove the goiter.
When should I call my healthcare provider?
Tell your healthcare provider if your symptoms get worse or you have new symptoms.
