E00-E07: Disorders of thyroid gland

E03: Other hypothyroidism

Other hypothyroidism is a group of conditions where the thyroid gland, a small butterfly-shaped gland in your neck, does not produce enough thyroid hormones to meet your body's needs. These conditions can be caused by a variety of reasons including a problem with the pituitary gland, inflammation of the thyroid gland, or the body's immunity attacking the thyroid gland. Symptoms commonly include tiredness, weight gain, depression, and sensitivity to cold. If left untreated, these disorders can progress to cause more serious health problems, such as heart disease, joint pain, and infertility. The thyroid hormones impact several systems in the body including metabolism regulation, growth and development during childhood, and keeping the heart, brain, and other organs functioning properly. It's crucial to mention that the conditions vary widely in presentation as they are typically influenced by the underlying cause and the body's response. Each person's experience with hypothyroidism may vary in severity and the presence of symptoms.
