Thyroid disorders, particularly hypothyroidism, hyperthyroidism, thyroid nodules, and thyroid cancer, are increasingly prevalent in India, affecting around 42 million people. Several factors contribute to this high incidence, including iodine deficiency despite widespread iodized salt use, genetic predispositions, autoimmune diseases such as Hashimoto's thyroiditis and Graves' disease, environmental toxins, and lifestyle factors like stress and poor diet.
Hypothyroidism, characterized by insufficient thyroid hormone production, is especially common in women, leading to symptoms like fatigue, weight gain, and depression. On the other hand, hyperthyroidism involves excessive hormone production, often due to Graves' disease, causing symptoms like weight loss, rapid heartbeat, and irritability. The rise in thyroid cancer, particularly papillary thyroid cancer, which is generally more treatable than other types, adds to the public health challenge, underscoring the need for increased awareness and early detection efforts.
