What are the hazards of low thyroid stimulating hormone

Low levels of thyroid stimulating hormone may cause hyperthyroidism, cardiovascular system abnormalities, metabolic disorders, psychiatric symptoms, and bone health problems. The main hazards include palpitations, weight loss, anxiety, insomnia, osteoporosis, etc., which require timely intervention.

1. Risk of hyperthyroidism:

The most common harm of low thyroid stimulating hormone is the induction of hyperthyroidism. Excessive secretion of thyroid hormones can lead to an abnormal increase in basal metabolic rate, and patients may experience typical symptoms such as persistent tachycardia, fear of heat and excessive sweating, overeating but weight loss. Long term uncontrolled hyperthyroidism may lead to thyroid crisis.

2. Cardiac damage:

Thyroid hormones have a direct stimulating effect on the myocardium. In a state of low thyroid stimulating hormone, patients are prone to cardiac arrhythmias such as sinus tachycardia and atrial fibrillation, and increased cardiac load may lead to myocardial hypertrophy. Middle aged and elderly patients may develop heart failure, and electrocardiogram often shows ST-T segment changes.

3. Metabolic abnormalities: Abnormal elevation of thyroid hormones can accelerate the metabolism of three major nutrients. Patients may experience symptoms such as blood sugar fluctuations, abnormal breakdown of blood lipids, and excessive protein consumption. Some patients are accompanied by worsening of diabetes, and increased urinary calcium excretion is prone to lead to electrolyte disorder.

4. Neurological symptoms:

The central nervous system is extremely sensitive to changes in thyroid hormones. Patients often experience psychological symptoms such as emotional instability, anxiety, restlessness, and difficulty falling asleep. Some may also show signs of nerve excitation such as subtle tremors in the hands and hyperactive tendon reflexes. Severe cases may experience manic episodes or consciousness disorders.

5. Skeletal disorders:

Thyroid hormones enhance bone resorption, and long-term low levels of thyroid hormones may accelerate bone loss. Postmenopausal women are more likely to develop osteoporosis and increase the risk of fractures. The detection of bone metabolism markers often shows an increase in osteocalcin and a decrease in T value in bone density examination.

It is recommended to regularly monitor thyroid function indicators, control iodine intake in daily life, and avoid high iodine foods such as seaweed and seaweed. Ensure sufficient intake of calcium and vitamin D, dairy products, dark green vegetables, and fish are good sources. Moderate weight-bearing exercises such as walking and Tai Chi can help maintain bone density. When obvious symptoms such as palpitations and weight loss occur, seek medical attention as soon as possible to avoid adjusting medication dosage on one's own. Pregnant women need to pay special attention to changes in thyroid function to prevent them from affecting the development of the fetal nervous system.
