Hashimoto's disease is a condition in which your immune system attacks your thyroid, a small gland at the base of your neck below your Adam's apple. The thyroid gland is part of your endocrine system, which produces hormones that coordinate many of your body's functions.
Inflammation from Hashimoto's disease, also known as chronic lymphocytic thyroiditis, often leads to an underactive thyroid gland (hypothyroidism). Hashimoto's disease is the most common cause of hypothyroidism in the United States. It primarily affects middle-aged women but also can occur in men and women of any age and in children.
Doctors test your thyroid function to help detect Hashimoto's disease. Treatment of Hashimoto's disease with thyroid hormone replacement usually is simple and effective.

You might not notice signs or symptoms of Hashimoto's disease at first, or you may notice a swelling at the front of your throat (goiter). Hashimoto's disease typically progresses slowly over years and causes chronic thyroid damage, leading to a drop in thyroid hormone levels in your blood. The signs and symptoms are mainly those of an underactive thyroid gland (hypothyroidism).
Signs and symptoms of hypothyroidism include:
See your doctor if you develop these signs and symptoms:
You'll also need to see your doctor for periodic testing of your thyroid function if:
If you have high blood cholesterol, talk to your doctor about whether hypothyroidism may be a cause.
And if you're receiving hormone therapy for hypothyroidism caused by Hashimoto's disease, schedule follow-up visits as often as your doctor recommends. It's important to make sure you're receiving the correct dose of medicine. Over time, the dose you need to adequately replace your thyroid function may change.

Hashimoto's disease is an autoimmune disorder in which your immune system creates antibodies that damage your thyroid gland. Doctors don't know what causes your immune system to attack your thyroid gland. Some scientists think a virus or bacterium might trigger the response, while others believe a genetic flaw may be involved.
A combination of factors â including heredity, sex and age â may determine your likelihood of developing the disorder.

In general, your doctor may test for Hashimoto's disease if you're feeling increasingly tired or sluggish, have dry skin, constipation, and a hoarse voice, or have had previous thyroid problems or goiter.
Diagnosis of Hashimoto's disease is based on your signs and symptoms and the results of blood tests that measure levels of thyroid hormone and thyroid-stimulating hormone (TSH) produced in the pituitary gland. These may include:
In the past, doctors weren't able to detect an underactive thyroid (hypothyroidism), the main indicator of Hashimoto's disease, until symptoms were fairly advanced. But by using the sensitive TSH test, doctors can diagnose thyroid disorders much earlier, often before you experience symptoms.
Because the TSH test is the best screening test, your doctor will likely check TSH first and follow with a thyroid hormone test if needed. TSH tests also play an important role in managing hypothyroidism. These tests also help your doctor determine the right dosage of medication, both initially and over time.

Left untreated, an underactive thyroid gland (hypothyroidism) caused by Hashimoto's disease can lead to a number of health problems:
Myxedema (miks-uh-DEE-muh). This rare, life-threatening condition can develop due to long-term hypothyroidism as a result of untreated Hashimoto's disease. Its signs and symptoms include drowsiness followed by profound lethargy and unconsciousness.
A myxedema coma may be triggered by exposure to cold, sedatives, infection or other stress on your body. Myxedema requires immediate emergency medical treatment.
Birth defects. Babies born to women with untreated hypothyroidism due to Hashimoto's disease may have a higher risk of birth defects than do babies born to healthy mothers. Doctors have long known that these children are more prone to intellectual and developmental problems. There may be a link between hypothyroid pregnancies and birth defects, such as a cleft palate.
A connection also exists between hypothyroid pregnancies and heart, brain and kidney problems in infants. If you're planning to get pregnant or if you're in early pregnancy, be sure to have your thyroid level checked.
