The high TSH after operation is caused by insufficient replacement of thyroxine, so it is necessary to increase the replacement dose of artificial thyroxine. Patients with hypothyroidism have low thyroid function, so it is necessary to supplement enough protein and heat to improve thyroid function. During hypothyroidism, although the synthesis of plasma cholesterol is not fast, its excretion is slow, so its blood concentration increases, triglycerides and lipoproteins increase, so it is appropriate to limit the intake of fat. Thyroxine deficiency can affect the synthesis of erythropoietin, leading to the decline of hematopoietic function of bone marrow, and it is also related to menorrhagia, iron absorption disorder, gastric acid factor, vitamin B 12 and folic acid deficiency. For the above reasons. The diet of hypothyroidism patients must pay attention to the following points:
(1) Supplementing appropriate amount of iodine
(2) Avoid using goiter substances: Avoid eating soybeans, cabbage, cabbage, rape, cassava, walnuts, etc. To avoid goiter.
(3) Adequate supply of protein.
(4) Restricting fat and high cholesterol diet: Patients with hypothyroidism are often accompanied by hyperlipidemia, which is more obvious in primary hypothyroidism. Fat diet and high cholesterol diet should be restricted.
(5) correct anemia and supplement rich vitamins: anemia patients should supplement iron-rich diet, vitamin B 12, such as animal liver and folic acid, and supplement liver preparations when necessary.
