Thyroid disorders, particularly [hypothyroidism]() and [hyperthyroidism](), can have a significant impact on gynecological health and may present with neck symptoms. The thyroid gland, located in the neck, is responsible for regulating metabolism and can influence menstrual cycles, fertility, and overall energy levels. Symptoms such as neck swelling or discomfort, alongside menstrual irregularities, should prompt evaluation of thyroid function.
