Thyroid disease is a major issue all over the world. Thyroid illness is also very common in India. Numerous thyroid disease studies have revealed that 42 million Indians are affected by the disease. Thyroid ailments are classified into five types in India: hypothyroidism, hyperthyroidism, goitre and iodine deficiency disorders, Hashimoto's thyroiditis, and thyroid cancer.
