Women at 17 weeks need to check some routine checkups as well as special checkups. 1. Routine checkups: 17 weeks pregnant women belong to the middle stage of pregnancy, 17 weeks pregnant women are mainly checked for some routine items, such as height, weight, blood pressure, breast, blood routine, urine routine, etc., in order to rule out the presence of hypertension, diabetes and other chronic diseases and other physical abnormalities, in order to ensure the health and safety of pregnant women. Pregnant women in the 17th week of pregnancy should also undergo basic programs such as measurement of uterine height, measurement of abdominal circumference, ultrasound, etc., to observe the development of the fetus. 2. Special checkup programs: Down syndrome screening is available at 17 weeks of pregnancy. For people with higher risk during pregnancy, such as those who are over 35 years old, have a family history of illness, or have a history of chronic illness, they can be screened through amniocentesis and non-invasive DNA. As the physical examination programs of hospitals around the world are different, pregnant women can consult their local hospitals according to their own situation. Pregnant women should carry out activities appropriately after mid-pregnancy, and undergo regular maternity checkups and so on.
