Hypothyroidism can cause symptoms in multiple systemic systems. Common symptoms include fatigue, intolerance to cold, weight gain, slowed reaction times, lethargy, depression, and constipation. Hypothyroidism often affects muscles and joints, causing muscle weakness, cramps, and pain. Cardiovascular symptoms are also common, such as bradycardia, pericardial effusion, and decreased cardiac output. Hematologic manifestations primarily include anemia, while digestive symptoms commonly include anorexia, abdominal distension, and constipation. In severe cases, paralytic ileus may occur.
1. Congenital Causes
Congenital defects of the thyroid gland, such as underdeveloped or underdeveloped, result in a deficiency of the enzymes required to synthesize thyroid hormones, hindering thyroid hormone production. Consequently, thyroid hormone production does not reach the required levels, leading to symptoms of hypothyroidism.
2. Genetic Factors
Hypothyroidism is a hereditary condition. If a parent has hypothyroidism, their children's thyroid glands are more susceptible to the pathogens causing it. Exposure to the pathogen, combined with excessive fatigue or mental stress, can weaken one's immune system and trigger hypothyroidism.
3. Impact of Thyroid Disease
People who are affected by thyroid disease can also develop hypothyroidism. Some undergo thyroid surgery, resulting in complete thyroid removal or excessive removal of thyroid tissue. This prevents the thyroid gland from producing thyroid hormones properly, leading to hypothyroidism.
4. Chronic Iodine Deficiency
Iodine is a crucial raw material for the synthesis of thyroid hormones. Chronic iodine deficiency in the body leads to insufficient thyroid hormone production, resulting in decreased production. Pathologies in the hypothalamus and pituitary gland can lead to insufficient secretion of thyroid-stimulating hormone, preventing the body from producing thyroid hormones, thus causing hypothyroidism.
5. Emotional Stimulation
Mental stimulation can lead to liver qi stagnation, which in turn leads to spleen deficiency, disrupting transport and transformation, and causing internal dampness and phlegm, which in turn leads to hypothyroidism.
Treatment of Hypothyroidism
Hypothyroidism is primarily treated with thyroid hormone supplementation. Doctors will tailor a personalized treatment plan based on the patient's specific circumstances, adjusting medication dosage and type to restore thyroid hormone levels to normal. Generally, synthetic levothyroxine and natural thyroid extract are used to treat hypothy and control thyroid hormone balance or promote metabolism.
