2, especially face. Sometimes there will be sallow complexion, facial edema, and eyes become hard to open. These are some manifestations of hypothyroidism.
3. Cardiovascular system. Hypothyroidism can also cause cardiovascular disease, which is a kind of heart disease caused by hypothyroidism. I hope everyone can pay attention to it in peacetime.
4. Patients may have obvious disorder of lipid metabolism, such as hypercholesterolemia, hypertriglyceridemia and high β-lipoproteinemia, often accompanied by atherosclerosis, and the incidence of coronary heart disease is higher than that of the general population. However, due to the low metabolic rate of surrounding tissues, decreased cardiac output and decreased myocardial oxygen consumption, angina pectoris and heart failure rarely occur. Sometimes blood pressure is high, but diastolic pressure is more common. Electrocardiogram showed low voltage, T wave inversion, QRS wave broadening and P-R interval lengthening.
5. Digestive system. The patient has anorexia, constipation, abdominal distension and even paralytic intestinal obstruction. About half of the patients have complete gastric acid deficiency.
6. Muscle and joint system. Muscles are not easy to contract and relax slowly, and they often feel muscle pain and stiffness. After a cold, osteoporosis, joint stiffness, pain, inflexibility and increased stiffness, like chronic arthritis.
7. Endocrine system. Sexual desire declines, male impotence, and female patients may have symptoms such as galactorrhea, irregular menstruation or amenorrhea, and infertility. Adrenal cortex function is low, and blood and urine cortisol are reduced. Primary hypothyroidism is sometimes accompanied by autoimmune adrenocortical hypofunction and/or type I diabetes, which is called Schmidt syndrome.
8. Other performances. All kinds of intermediate metabolism are low, the enzyme clearance rate is reduced, and the concentrations of cholesterol, triglyceride, low density lipoprotein and muscle enzyme are increased. If combined with diabetes, the condition of diabetes is relatively relieved, and the dosage of insulin and oral hypoglycemic agents is reduced.
