The increasing pressure of work life and the richness of night life make the number of people suffering from sleep disorders increasing day by day. However, in stark contrast, the whole day drowsy sleep is also a large number of people. Faced with the embarrassment of “spring sleepiness, autumn fatigue, summer snooze”, I believe most people’s first choice is to turn to coffee, strong tea or cola and other caffeine-containing beverages. I do not know the stimulation of external chemicals alone, not only can not solve the root of the problem, there may even make the body dependence. In addition to neurasthenia, menopausal syndrome, endocrine disorders, thyroid disorders account for an increasing proportion of the exhaustion. According to statistics, there are currently more than 200 million people suffering from thyroid disease, there are “easy fatigue” people may wish to check the thyroid. Chronic fatigue syndrome – an epidemic of urban people The hectic urban life has given birth to the “sleepless generation”. For them, even if they adhere to the healthy routine of early to bed and early to rise, to ensure eight hours of sleep every night, the next day is always sickly sleepy, and then the intense work, study can not make them excited, at any time and anywhere may doze off. In addition to drowsiness, there are also manifestations such as pain in the throat, joints or muscles, and swollen lymph nodes. However, when they go to the hospital for routine examinations such as films and blood tests, they cannot find any organic lesions. If you suffer from all these discomforts, it is likely that you are suffering from chronic fatigue syndrome. From the pathological point of view, chronic fatigue syndrome is a functional disease, which is mainly treated by non-pharmaceutical methods such as adjusting lifestyle, improving nutrition and strengthening exercise. However, there is a clinical category of diseases whose initial symptoms are extremely similar to chronic fatigue syndrome, which can easily cause confusion and patient neglect, and the consequences of negligent treatment are very serious, which is thyroid disease. As the name suggests, the thyroid gland is a butterfly-shaped endocrine organ located on the thyroid cartilage in the neck of the human body, and its secretion of thyroid hormones is essential for maintaining normal human metabolism, growth and development. Doctors often use this analogy to describe the thyroid gland as the human engine. If the level of thyroid hormones in the body is not sufficient, the metabolic rate will be reduced and the whole person will be physically and mentally tired. In addition, this is accompanied by dryness of the skin, eyes, mouth and tongue, poor sleep quality and appetite, menstrual disorders and loss of libido. If there is persistent fatigue that is difficult to relieve and cannot be explained, the first thing to think about is whether there is something wrong with the thyroid gland. An ultrasound of the neck and a blood test of the “five thyroid function tests” can provide a preliminary assessment of the health of the thyroid gland. The most common disease that causes hypothyroidism is Hashimoto’s thyroiditis, an autoimmune disease first reported by Japanese doctors. The immune system, which is supposed to monitor the invading microorganisms and mutated cells in the body, starts to attack its own thyroid gland, leading to a decrease in thyroid hormone secretion, which in turn causes fatigue and other symptoms. To confirm the diagnosis, in addition to the ultrasound and blood tests described above, a thyroid nuclear scan is required to fully evaluate the iodine uptake by the thyroid gland. “Patients in the acute phase of Hashimoto’s disease with more pronounced symptoms such as goiter and pain may be treated with hormone therapy under medical supervision to suppress the overactive immune function. If thyroid hormone levels are significantly lower, thyroxine replacement therapy may be required depending on the condition. Hyperthyroidism can cause fatigue? Yes! The opposite of hypothyroidism is “hyperthyroidism”. Nowadays, the incidence of this disease is very high, especially among middle-aged women who are under the pressure of work and family, and are particularly vulnerable to hyperthyroidism. As hyperthyroidism has been introduced in various media, people are familiar with its symptoms – hand trembling, hyperactivity, irritability, tachycardia, spontaneous sweating and night sweating. …… It is not known that some patients with hyperthyroidism may also show symptoms that are incompatible with the above –Lethargy.
