Minimally invasive treatment for thyroid nodules
An overview of the most common thyroid conditions and how they are managed.
Thyroid problems affect an estimated 20 million Americans, yet up to 60% of those with thyroid disease are unaware of their condition. The thyroid gland can be affected by a range of disorders — from autoimmune diseases to structural abnormalities — each requiring different approaches to diagnosis and treatment.
Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormone. The most common cause is Hashimoto's thyroiditis, an autoimmune condition. Other causes include thyroid surgery, radiation therapy, and certain medications. It is treated with daily thyroid hormone replacement medication, most commonly levothyroxine.
Hyperthyroidism occurs when the thyroid produces too much hormone. Graves' disease — an autoimmune disorder — is the most common cause. Other causes include toxic multinodular goiter and thyroid nodules. Treatment options include anti-thyroid medications, radioactive iodine therapy, and surgery.
Hashimoto's thyroiditis is the most common autoimmune thyroid disease and the leading cause of hypothyroidism in developed countries. The immune system attacks the thyroid gland, gradually reducing its ability to produce hormones. It is more common in women and often runs in families. Treatment focuses on managing hypothyroidism with hormone replacement.
Graves' disease is an autoimmune disorder that causes hyperthyroidism. The immune system produces antibodies that stimulate the thyroid to produce excess hormone. It can also cause Graves' ophthalmopathy — eye problems including bulging eyes, double vision, and light sensitivity. Treatment aims to reduce thyroid hormone production.
Thyroid nodules are lumps that form within the thyroid gland. Most are benign, but some can be cancerous. A goiter is an abnormal enlargement of the thyroid gland and can occur with hypothyroidism, hyperthyroidism, or normal thyroid function. Both conditions are evaluated with ultrasound and, if needed, biopsy.

Dr. Guttler's comprehensive guide to understanding an underactive thyroid: causes, symptoms, diagnosis, and treatment options.
Lecture 3: Hyperthyroidism & Graves' Disease
An overactive thyroid can cause heart palpitations, weight loss, and anxiety. Dr. Guttler explains Graves' disease, toxic nodules, and treatment choices.
Lecture 4: Goiter & Benign Thyroid Nodules
Most thyroid nodules are benign. Dr. Guttler explains what causes goiters and nodules, how they are evaluated, and when treatment is needed.
