THYROID

The thyroid is a butterfly-shaped gland in the front of the neck. Its primary function is to produce the hormones triiodothyronine (T3) and thyroxine (T4), which help regulate metabolism and aid in brain development, digestive function, muscle control, and mood regulation.

When the thyroid produces either too much or too little of these hormones, it causes the gland to work inefficiently, leading to disorders such as hyperthyroidism and hypothyroidism, the two most common types of thyroid disease. Other thyroid-related conditions include thyroiditis, thyroid nodules, goiter, and thyroid cancer
