Y42: Hormones and their synthetic substitutes and antagonists, not elsewhere classified
Y42.1: Thyroid hormones and substitutes
Thyroid hormones and substitutes relate to medications designed to mimic or replace naturally occurring hormones within the thyroid gland. Problems begin when the thyroid gland in the body produces either too much or too little thyroid hormones - conditions known as hyperthyroidism and hypothyroidism respectively. This can lead to a variety of symptoms including fatigue, weight fluctuations, mood changes, and temperature sensitivity. Doctors often prescribe thyroid hormones and substitutes to patients in order to regulate these hormone levels and relieve symptoms. However, it's important to know that these medications, while useful, can potentially cause adverse reactions in some individuals. This category can include issues such as an allergic reaction to the medication, or the incorrect dosage leading to symptoms of hyperthyroidism or hypothyroidism.
