What are the risks of untreated thyroid dysfunction?

Untreated thyroid dysfunction, whether hypothyroidism or hyperthyroidism, can lead to serious health complications. Hypothyroidism can result in weight gain, heart problems, depression, and in severe cases, myxedema coma. Hyperthyroidism may cause weight loss, anxiety, osteoporosis, and heart conditions such as atrial fibrillation. Both conditions can also affect fertility and pregnancy. Early detection and treatment of thyroid disorders through regular thyroid function tests (TFTs) are crucial for maintaining overall health and preventing long-term damage.
