What Are the Symptoms of Thyroid Dysfunction Due to Toxic Exposure?
Symptoms of thyroid dysfunction can vary depending on whether the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism). Common symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, and depression. Hyperthyroidism may manifest as weight loss, heat intolerance, anxiety, and increased heart rate. Toxic exposure can exacerbate these symptoms by further disrupting normal thyroid function.
