A thyroid problem, also known as thyroid disorder, encompasses a range of conditions that affect the thyroid gland, a small butterfly-shaped gland located in the front of the neck. The thyroid gland produces hormones that regulate metabolism, growth, and development, and thyroid problems occur when the gland produces too much or too little of these hormones.
Thyroid problems are relatively common, affecting millions of people worldwide. They can range from mild to severe and can cause a variety of symptoms, including fatigue, weight gain or loss, changes in mood, and irregular menstrual cycles. If left untreated, thyroid problems can lead to serious health complications, such as heart disease, osteoporosis, and infertility.
