Top 5 Causes of Goiter

Goiter Definition: Goiter refers to any enlargement of the thyroid gland that is not caused by cancer, often misunderstood as just a visible lump due to iodine deficiency. Iodine Deficiency: The leading cause of goiter worldwide, where lack of iodine leads to reduced thyroid hormone production and gland enlargement. Hashimoto's Thyroiditis: An autoimmune condition causing the body to attack the thyroid gland, leading to decreased function and an enlarged thyroid. Graves' Disease: Another autoimmune disease where antibodies stimulate the thyroid gland, causing overactivity and elevated thyroid hormone levels. Thyroid Nodules: Lumps in the thyroid that can be benign or malignant, necessitating careful examination and monitoring. Symptoms of Goiter: Include visible enlargement of the thyroid, difficulty swallowing or breathing, hoarseness, coughing, and thyroid hormone imbalance. Graves' Disease Symptoms: Anxiety, irritability, tremor, heat sensitivity, weight loss, irregular menstrual periods, and bulging eyes. Treatment for Iodine Deficiency: Involves the use of iodine-enriched salt to prevent and treat goiter caused by iodine lack. Hashimoto's Treatment: Primarily hormone replacement therapy to address hormone deficiency. Graves' Disease Treatment: Options include antithyroid medications, radioactive iodine therapy, or surgery based on severity. Monitoring Thyroid Nodules: Most nodules are benign and simply monitored over time unless malignant features are detected. Impact of Pregnancy on the Thyroid: hCG hormone during pregnancy can mimic TSH, leading to temporary thyroid gland enlargement. Visible and Non-visible Nodules: Nodules over 3 cm can be visible and potentially cause symptoms, while those under 2 cm typically do not. Significance of Thyroid Function Tests: High TSH and low thyroxine levels indicate Hashimoto's, while low TSH and high thyroid hormones suggest Graves' disease. Commonality Among Women: Both Hashimoto's thyroiditis and Graves' disease are more common in women, particularly affecting those of middle age or younger.
