I believe we are not unfamiliar with this disease, today I will talk to you about the hazards of hypothyroidism, many hypothyroid patients are dragging the disease is not to go to treatment is not aware of the hazards of hypothyroidism, then the following to talk to you about the symptoms of hypothyroidism and diet, I hope you can seriously look down. The hazards of hypothyroidism So what kind of hazards does hypothyroidism need to be specially explained to you, to know the hazards of hypothyroidism is very big, many hypothyroid patients are because of this condition deterioration, and finally can not be cured. 1, hypothyroidism will affect the growth and development of children suffering from hypothyroidism, will lead to intellectual backwardness or even dementia, short stature, etc.. Thyroid hormone has a promotional effect on growth hormone, thyroid hormone deficiency will affect the growth-promoting effect of growth hormone, children with hypothyroidism often show growth retardation, slow epiphyseal healing, delayed bone age. Adolescents with hypothyroidism show delayed sexual development, and a few show precocious sexual maturity. 2, hypothyroidism will affect sexuality and fertility After suffering from hypothyroidism, female patients show more menstruation, prolonged periods, even amenorrhea, not easy to conceive, even if successful pregnancy, miscarriage, stillbirth, the chance of congenital hypothyroidism after birth is also very large; for men, the performance of low libido, breast development, impotence, not easy to have children; and hypothyroidism will be hereditary, hypothyroid patients have a high chance of offspring suffering from hypothyroidism The risk of hypothyroidism in the offspring is also high. Therefore, if you have hypothyroidism, your doctor will recommend that you have children after you are cured. 3, hypothyroidism will affect the cardiovascular system When the thyroid hormone is low, physical examination reveals that the patient has a slow and weak heartbeat, low heart sound, enlarged heart, bradycardia, swelling of the lower limbs, increased blood pressure, and reduced pulse pressure difference. Myocardial pseudohypertrophy, electrocardiogram shows low voltage, and sinus bradycardia. About 30% of patients have pericardial effusion, and in severe cases, pleural or abdominal effusion will also occur. 4, hypothyroidism will affect muscle and joint Hypothyroidism patients clinically show weakness, muscle pain, tonicity, spasm, edema and hypertrophy, elevated serum CPK, LDH and AST, isoenzyme mainly from the transverse muscle. The Achilles tendon reflex relaxation period of hypothyroid patients is significantly prolonged, but not sensitive enough. 5, hypothyroidism will affect the gastrointestinal system The smooth muscle tone of esophagus, stomach, gallbladder, small intestine and colon is weakened, gastrointestinal peristalsis is slow, emptying time is prolonged, gastric acid secretion is reduced, and serum anti-gastric wall cell antibody is positive. Patients show loss of appetite, abdominal distension, nausea, low gastric acid, and difficulty in defecation. 6, hypothyroidism will affect the hematological system About 25% of hypothyroid patients show anemia, most of them are mild or moderate orthochromic or hypochromic small cell anemia, a few are macrocytic anemia. The reasons for reduced erythropoiesis are: (1) reduced renal erythropoietin due to decreased metabolism and reduced oxygen consumption, (2) the effect of hypothyroidism on erythropoietin precursors, (3) hypothyroid patients are mostly women with increased menstruation, and (4) lack of gastric acid and impaired absorption in the gastrointestinal tract. Some hypothyroid patients (about 12%) also show macrocytic anemia, positive antibodies to gastric lining cells or internal factor antibodies, and vitamin B12 or folic acid deficiency, showing macrocytic anemia.
