Fetal development

The 22 week old fetus is now about 19cm long and weighs 350g At this time, the fetal weight began to increase significantly, and it looked like a baby. Because the baby's weight is still too small The skin is still wrinkled, red and looks like a little old man Of course, this wrinkle also leaves room for the growth of subcutaneous fat. At 22 weeks, the fetus looks slippery, as if covered with a layer of white and greasy material, which we call Foetal fat 。 Fetal fat can prevent the skin from being damaged by long-term immersion in amniotic fluid. Many babies are born with this kind of fetal fat. Besides baby's tooth At this time, the tooth germ of permanent teeth is also developing.

Symptoms and prevention of anemia

Anemia is one of the common complications during pregnancy. After pregnancy, the plasma increases, which is more than that of red blood cells. Therefore, the blood is diluted, and the diagnostic criteria for anemia in pregnant women are relatively low. Anemia can be diagnosed when hemoglobin is below 10 grams and red blood cells are below 3.5 million. Anemia will be aggravated after pregnancy in women with anemia. Pregnancy anemia is the most common iron deficiency anemia, megaloblastic anemia is rare, and aplastic anemia is extremely rare.

Anemia symptoms

·Anemia is very dangerous for pregnant women or fetuses. Mild anemia occurs when general hemoglobin drops to 8g, and severe anemia occurs when hemoglobin drops below 6g 。 Pregnant women with anemia are prone to pregnancy induced hypertension syndrome, and the situation is also serious. When severe anemia occurs, there will be panic, shortness of breath, dyspnea, anemic heart disease, and even heart failure.

·During delivery, because of anemia, uterine inertia often occurs, which leads to prolonged pregnancy and delivery process and the need for surgery, and postpartum hemorrhagic shock is prone to occur.

·As a result of anemia, the ability of red blood cells to deliver oxygen decreases, and the fetus suffers from intrauterine hypoxia, growth retardation, and is prone to miscarriage, premature delivery, low birth weight, and stillbirth.

Diet prevention

·The best blood tonic food is carotene containing iron, such as: golden needle, longan meat, carrots, spinach, black beans.

·Animal food with high iron content includes egg yolk, beef, liver, kidney, etc.

·In addition to improving nutrition, moderate or above anemia can be treated with oral iron, such as ferrous sulfate, ferrous gluconate, ferrous fumarate and Weixue Granule;

·In addition to taking iron, pregnant anemia also needs to take small doses of folic acid, 400 micrograms per day. Be careful not to increase the amount of folic acid without authorization.

·Take some vitamin C, which is good for iron absorption.
