Struma is a medical condition characterized by an enlargement of the thyroid gland, which is located in the neck. This enlargement can occur due to various factors, including iodine deficiency, autoimmune diseases like Hashimoto's thyroiditis, or the presence of nodules. Symptoms may include visible swelling in the neck, difficulty swallowing, or changes in voice. The condition can be classified into different types, such as simple goiter and toxic goiter. Treatment options vary depending on the underlying cause and may include medication, iodine supplementation, or surgery in severe cases. Regular monitoring and medical evaluation are essential for managing struma effectively.
