Uncovering Congenital Hypothyroidism in Adulthood: A Case Study Emphasizing the Urgency of Screening and Clinical Awareness.

Congenital hypothyroidism (CH) is an endocrine disorder primarily diagnosed during the neonatal period through routine screening. Screening programs have been established in most developed countries. However, routine neonatal screening is not available in India, and the mainstay for diagnosis is clinical awareness. In this report, we present a case of CH diagnosed for the first time in a 20-year-old male who sought medical attention at our hospital's emergency department due to fever and altered sensorium. This case report elucidates the implications of a delayed diagnosis of CH, shedding light on the pivotal role of neonatal screening and the need for enhanced awareness within the healthcare community and among families.
