In the 1970s, when I was a student, a male student in the same class had very special big goldfish eyes and a short, thick, fat neck, and his protruding eyeballs left a deep impression on me. A few years later, I happened to ask about that male classmate, but he was no longer alive, and I heard from an alumnus that the “big neck disease” had taken his youthful life. After a long time, I learned that “big neck disease” is a kind of thyroid disease – goiter. In fact, it is not an incurable disease, but because of the indifferent treatment of the disease and the lack of medical knowledge in those days, the best time to diagnose and treat the disease was missed. As we know, the thyroid gland is a small organ with important functions, which manufactures, stores and releases thyroid hormones into the bloodstream to regulate the body’s metabolism. These hormones are important for maintaining the normal functioning of all tissues and organs of the body. Common thyroid disorders include hyperthyroidism or hyperthyroidism, hypothyroidism or hypothyroidism, thyroid tumors, thyroiditis, and goiter. More than 300 million people worldwide suffer from thyroid disease, but at least half of them are unaware of their disease. Thyroid disorders are a health hazard, so it is important for the public to be aware of the prevention of the disease and to follow the principle of “early detection and treatment” to avoid delaying the disease. If you are a woman over 35 years old or have a family history of thyroid disease, or if you have the following symptoms: fatigue, sleepiness, depression, memory loss, slow brain thinking, weight gain and sometimes constipation, dry skin, brittle nails, menstrual disorders, infertility, swelling of the neck, it is important to have your thyroid gland checked regularly. Thyroid function. Untreated thyroid disease can lead to cardiovascular disease risk, increased risk of osteoporosis (especially in postmenopausal women), and hyperthyroidism in women during pregnancy can lead to miscarriage, delayed intrauterine delivery, premature birth and hyperthyroid crisis, which can be life-threatening in severe cases. Treatment for thyroid disorders is easy, safe and inexpensive. A simple blood thyroid stimulating hormone (TSH) test by a physician can determine if a patient has abnormal thyroid function, so that effective treatment can be used to control the disease and improve the patient’s quality of life and live as normal.
