Hashimoto’s disease can affect thyroid function, but symptoms alone cannot identify it.

Hashimoto’s disease is an autoimmune disorder that can cause an underactive thyroid. Evaluation uses clinical history and appropriate testing.

Hashimoto’s disease involves the immune system and the thyroid gland.

NIDDK explains that antibodies and immune cells can damage the thyroid and reduce its ability to make thyroid hormone. Thyroid hormones affect how the body uses energy.

Possible symptoms overlap with many other conditions. Fatigue, weight change, feeling cold, dry skin, muscle or joint symptoms, mood changes, and menstrual changes do not establish a diagnosis on their own.

Diagnosis and treatment decisions depend on clinical testing.

A clinician may use thyroid-function blood tests and thyroid-antibody tests, with imaging in selected situations. Results need to be interpreted in the context of symptoms, medicines, pregnancy, and other health factors.

This page does not recommend supplements, dietary exclusions, thyroid medicine, or a GBH-specific treatment program.
