What is primary hyperthyroidism and secondary hyperthyroidism

According to the causes of thyroid antibodies, they can be divided into three categories: primary, secondary and high-functioning adenoma.

Primary thyroid antibodies are the most common and are characterized by hyperactivity at the same time as thyroid enlargement. Most patients are between 20 and 40 years old. Glandular enlargement is diffuse, bilaterally symmetrical, and often accompanied by proptosis.

Secondary antibodies are less common, such as those secondary to nodular goiter, in which patients have had nodular goiter for many years before they develop hyperfunctional symptoms. The age of onset is more than 40 years old. The glands are nodular and enlarged, with many asymmetrical sides and no proptosis, and myocardial damage is prone to occur.

High-functioning adenoma, rarely, a solitary autonomic high-functioning nodule within the thyroid gland in which the thyroid tissue surrounding the nodule is atrophic and absent proptosis.

Hyperthyroidism is a hypermetabolic disease, if there are the above symptoms, it means that the problem of medication should be considered, not only the problem of maintenance. Whether to use medication or depends on the patient's examination results, according to the thyroid function test results to consider the use of anti-hyperthyroid drugs, hyperthyroidism is a disease that can be **, as long as you adhere to the standard medication year, it can generally be **.

Hello, primary hyperthyroidism refers to hyperthyroidism caused by a disease of the thyroid gland itself, and secondary hyperthyroidism refers to hyperthyroidism that arises secondary to other diseases, such as adrenal or pituitary disorders. Whether it is primary or secondary, eat a high-calorie, high-protein, high-vitamin, and low-fiber diet to maintain a happy mood. Don't get tired.

a.Degree of rapid pulse.

b.Pulse pressure increases, systolic blood pressure increases.

c.The sequential relationship between thyroid gland swelling and the symptoms of hyperthyroidism in the posture is examined.

d.Degree of increase in basal metabolic rate.

Sequential relationship between uptake rate and hyperthyroidism.

Correct answer: c

Answer] Xunqing: c

TSH measurement is the most sensitive indicator of thyroid function, and it is also a sensitive index to reflect the function of the hypothalamic-pituitary-thyroid gland axis, distinguish between primary and secondary hyperthyroidism, and is especially important for the diagnosis of subclinical hyperthyroidism and hypothyroidism.

Answer]: B Primary hyperthyroidism is the most common and refers to the presence of hyperfunctional symptoms at the same time as the enlargement of the thyroid gland. The age of the destroyer is mostly in 20 to 40 years. The glands are often diffusely enlarged, symmetrical on both sides, and often accompanied by proptosis.

There are two types of hyperparathyroidism: primary and secondary.

Primary hyperparathyroidism is caused by excessive secretion of PTH by parathyroid hyperplasia, adenoma or adenocarcinoma, which is not affected by the feedback of blood calcium, so that blood calcium continues to increase.

Secondary hyperparathyroidism is generally due to compensatory hypertrophy and hyperfunction of the parathyroid glands caused by severe renal insufficiency, vitamin D deficiency, bone lesions, gastrointestinal malabsorption, and other reasons caused by hypocalcemia.

In both cases, bone decalcification is common, but calcium is elevated in primary hyperparathyroidism and decreased in secondary hyperparathyroidism.

1. The parathyroid glands themselves have lesions, such as excessive hyperplasia, neoplastic changes or even cancer, which is medically called primary hyperparathyroidism;

2. Due to the existence of other diseases in the body, such as long-term vitamin D deficiency, small intestine function malabsorption or renal insufficiency, etc., blood calcium is lower than normal, and the parathyroid glands need to increase the secretion of parathyroid hormone to increase the blood calcium level, therefore, it can be regarded as compensatory hyperthyroidism, which is called secondary hyperparathyroidism;

The causes of secondary hyperparathyroidism are mainly divided into the following categories: hypocalcemia, hypercalcitonin secretion caused by various causes, hypercortisolism and renal tubular acidosis, chronic renal insufficiency, autoimmune renal tubular damage and other chronic kidney diseases.

Answer] :d analysis: Patients with hyperparathyroidism may have a family history of revisiting, which is autosomal dominant inheritance for leakage and slippage. Master the knowledge of "parathyroid disease".
