How is female hyperthyroidism caused

Elevated levels of female thyroid stimulating hormone may be caused by hypothyroidism, pituitary lesions, abnormal thyroid function during pregnancy, insufficient iodine intake, or medication effects. Elevated thyroid stimulating hormone is usually manifested as symptoms such as fatigue, fear of cold, weight gain, and menstrual disorders. It can be diagnosed through thyroid function tests, pituitary MRI, and other methods, and adjusted with medication such as levothyroxine sodium tablets and thyroid tablets according to medical advice.

1. Hypothyroidism

Hypothyroidism is a common cause of elevated levels of thyroid stimulating hormone, which may be related to factors such as autoimmune thyroiditis, thyroid surgery, or radiation therapy. Patients may experience symptoms such as dry skin, decreased memory, and slowed heart rate. After diagnosis, it is necessary to follow the doctor's advice to take levothyroxine sodium tablets for long-term replacement treatment, and regularly check thyroid function. Daily attention should be paid to keeping warm and avoiding excessive fatigue.

2. Pituitary lesions

Pituitary adenomas and other lesions may lead to abnormal secretion of thyroid stimulating hormone, usually accompanied by symptoms such as headache and visual impairment. Diagnosis needs to be confirmed through pituitary MRI and hormone level testing. Treatment should be based on the nature of the tumor, such as the use of bromocriptine tablets or surgical resection through the nasal sphenoid sinus. Regular monitoring of hormone levels is required after surgery, and some patients may require lifelong hormone replacement therapy.

3. Thyroid abnormalities during pregnancy

Elevated levels of human chorionic gonadotropin during pregnancy may inhibit the secretion of thyroid stimulating hormone, and some pregnant women may experience temporary thyroid dysfunction. Symptoms include worsening morning sickness and increased heart rate. Differential diagnosis through thyroid antibodies and ultrasound examination is required. Mild abnormalities can be improved by adjusting iodine intake, while significant abnormalities require treatment with levothyroxine sodium tablets under the guidance of obstetrics and endocrinology.

4. Insufficient iodine intake

Long term iodine deficiency can lead to insufficient synthesis of thyroid hormones, feedback causing an increase in thyroid stimulating hormone. Commonly seen in people who strictly limit salt intake or have a preference for food, it may be accompanied by thyroid enlargement. It can be evaluated through urine iodine testing, and daily intake of iodine rich foods such as seaweed and seaweed can be increased. If necessary, take potassium iodide tablets according to medical advice. It should be noted that excessive iodine supplementation may also induce thyroid diseases.

5. Drug effects

Lithium preparations, amiodarone, and other drugs may interfere with thyroid hormone synthesis, leading to compensatory elevation of thyroid stimulating hormone. Usually appears after several weeks of medication, manifested as worsening of existing symptoms. It is necessary to check the medication history and adjust the medication plan or combine thyroid hormone preparations under the guidance of a doctor if necessary. Thyroid function monitoring should be strengthened during medication. When women experience elevated levels of thyroid stimulating hormone, it is recommended to maintain a regular sleep schedule and avoid staying up late and excessive mental stress. Adding selenium rich foods such as Brazil nuts and oysters to the diet can help with thyroid hormone metabolism. Pay attention to keeping warm in winter and avoid prolonged exposure to sunlight in summer. Women preparing for pregnancy or during pregnancy should pay special attention to thyroid function and undergo thyroid screening during regular prenatal check ups. All medication treatments must strictly follow the doctor's advice, and the dosage cannot be adjusted or stopped on one's own. Thyroid function and ultrasound should be rechecked every 3-6 months to timely evaluate the treatment effect.
