One of the most important glands in our body is the thyroid gland. It is shaped like a butterfly. When it doesn't function properly, it can make you feel nervous or tired and you may experience muscular weakness. Sudden weight gain or loss, dry skin patches, memory loss, and irregularities in your menstrual flow are all part of a thyroid disorder. It can even cause miscarriage and infertility. Not just that, women are 4 times more prone to thyroid disorders than men. The pooled prevalence of PPTD, defined as an abnormal thyroid-stimulating hormone (TSH) level, for the general population was 8.1%.1

The thyroid is one of the largest endocrine glands in the body. This gland is found in the neck, inferior to (below) the thyroid cartilage (also known as the Adam's apple) and at approximately the same level as the cricoid cartilage.
It has two cone-like lobes or wings, lobus dexter (right lobe) and lobus sinister (left lobe), and the two lobes are connected together by the isthmus. The gland is situated on the anterior side of the neck, lying against and around the larynx and trachea, reaching posteriorly over the oesophagus and carotid sheath. It starts cranially at the oblique line on the thyroid cartilage (just below the laryngeal prominence or Adam's apple) and extends inferiorly to the fifth or sixth tracheal ring.
