The water content of the corneas of pregnant women is higher than that of ordinary people. If you wear contact lenses, it is easy to cause corneal edema due to hypoxia, which can lead to corneal inflammation, ulcers, and eventually blindness. At the same time, the corneal curvature of pregnant women will also change with the pregnancy cycle and personal constitution, thereby increasing or decreasing the degree of myopia.
If you forcefully wear contact lenses, it is easy to cause significant damage to the new blood vessels in the eyeball due to discomfort, and even cause the corneal epithelium to fall off. In addition, once contact lenses are dirty, bacteria can easily breed, causing corneal inflammation, ulcers, and even blindness.
The second stupid thing that expectant mothers should not do: eat hot pot
According to testing by relevant departments, the infection rate of Toxoplasma gondii in chicken flocks is 61.4%. Toxoplasma gondii larvae often hide in the cells of infected mutton. Short-term heating when eating hot pot cannot kill the Toxoplasma gondii larvae parasitizing the cells of the meat slices. After eating, the larvae can pass through the intestinal wall in the intestine, spread throughout the body with the blood, and infect the fetus through the placenta. In severe cases, it can cause miscarriage, stillbirth, or affect fetal brain development, causing malformations such as microcephaly, macrocephaly (hydrocephalus), or anencephaly.
Stupid things that expectant mothers should not do 3: Take a hot bath
High fever can cause the death of fetal nerve cells and reduce the number of brain nerve cells. Brain nerve cells cannot regenerate after death and can only be replaced by part of glial cells. These glial cells lack the physiological functions of nerve cells, thus affecting intelligence and other brain functions, making children mentally retarded and slow to react.
Four stupid things that expectant mothers should not do: take a lot of calcium and cod liver oil
Long-term consumption of large amounts of cod liver oil and calcium-containing foods can cause loss of appetite, itchy skin, hair loss, allergic reactions, and proptosis of the eyeballs. At the same time, if the calcium concentration in the blood is too high, muscle weakness, vomiting and arrhythmia will occur, which is detrimental to the growth of the fetus. Some fetuses already have teeth at birth. In addition to the baby\’s precocious puberty, another possibility is that pregnant women take a large amount of vitamin A and calcium preparations or calcium-containing foods during pregnancy, causing the fetal tooth follicle to travel too far in the womb. Early calcification and eruption. If you need to seek medical treatment, you should take it as directed by your doctor.
