Thyroid diseases, particularly hypothyroidism (an underactive thyroid) and hyperthyroidism (an overactive thyroid), are among the most underdiagnosed health issues worldwide, with 150,000 people accumulated from 1998-2021 in South Korea alone. Yet, due to the subtle and often nonspecific nature of symptoms such as fatigue, unexplained weight changes, hair loss, and mood fluctuations, many individuals live for years without realizing they have a thyroid problem.
Early Detection in Thyroid Disease Diagnosis
Timely diagnosis of thyroid disorders can make a profound difference. When detected and treated promptly, patients can avoid serious complications from thyroid disorders, including infertility, cardiovascular disease, and metabolic imbalance.
Healthcare professionals recommend that adults, especially those over age 35 or with a family history of thyroid disease, include thyroid function tests as part of their annual health screenings. These simple blood tests measure hormone levels and allow doctors to spot potential dysfunction before it progresses.
Preventive steps may include:
- Scheduling regular thyroid screening
- Maintaining balanced iodine intake
- Monitoring persistent or unexplained symptoms
- Managing stress levels
- Following a healthy diet and staying physically active
- Avoiding excessive or unregulated supplement use
