Self-examination of the thyroid gland is done by observation, touching, and consultation with a doctor is recommended. The thyroid gland is a butterfly-shaped gland located in the neck below the thyroid cartilage, which secretes calcitonin and thyroxine, which play an important role in regulating the body’s vital activities. In order to keep an eye on the health of the thyroid gland and to detect thyroid abnormalities at an early stage, it is necessary to learn how to properly examine the thyroid gland. The examination of the thyroid gland is carried out with the help of the following two main points: 1. Observation: At this point we need to look in the mirror and find the glands located below the thyroid cartilage on both sides of the trachea. Then observe whether the thyroid gland is symmetrical and whether there is a bulge or lump. Then do a swallowing motion to feel whether there is pain, discomfort, whether the thyroid gland appears to move up and down. Normal thyroid glands are usually invisible. 2. Touching: At this time, use the left hand or right thumb, place it on the right side of the trachea under the laryngeal node, and the rest of the fingers touch the left thyroid or the right thyroid, and feel whether there is an oval, slightly hard lump during the swallowing action. If a lump is detected, it is likely to be a thyroid nodule, which requires a proper medical examination. It is recommended that people who notice any abnormality should seek medical attention.
