Dha is one of the polyunsaturated fatty acids, which has a positive effect on the brain intelligence development of the fetus. Pregnant women can appropriately increase their intake of such substances. Dha mainly exists in deep-sea fish such as eels, sardines and flounders, and seafood such as shrimps, crabs and shells. In addition, algae also contains rich dha. At present, the market is full of all kinds of dha, commonly known as brain gold, and the quality of many of these products can not be well guaranteed. Pregnant women should try their best to obtain such nutrients by means of food supplement, and if they have to, they should also buy products of corresponding brands in the regular market on the advice of doctors, and just add them in moderation to avoid blind large-dose supplementation.

Precautions for pregnancy

1, don't take medicine indiscriminately when you have a cold.

Indomethacin is a contraindicated antipyretic for pregnant women, and aspirin should not be used after 32 weeks of pregnancy. Antibiotics, if there is no clear evidence of bacterial infection in pregnant women with colds, such as tonsillitis, high blood pressure, cough with yellow phlegm, runny nose, etc., antibiotics are not needed. Expectorant and antitussive drugs are generally safe, but cough drugs containing iodine preparations should not be used by pregnant women.

2. What should pregnant women do if they have diarrhea?

Diarrhea in pregnant women may lead to miscarriage or premature delivery. First of all, don't eat for the time being, make proper rehydration, make up the water and electrolyte lost due to diarrhea, especially potassium ions, and also make up the lost heat. You can prepare some fluid-digestible porridge for pregnant women. If it is not very serious, it is good to have an empty stomach. At the same time of fluid replacement, we should closely observe whether the fetus is in good condition and whether there are signs of miscarriage or premature delivery. If the fetal condition is abnormal, you should go to the hospital immediately, and you should not be careless.

3. Correct sleeping position during pregnancy

In the early pregnancy (1~ 3 months), pregnant women can sleep at will, mainly in comfortable positions, such as supine position and lateral position. If you sleep on your stomach, or sleep with your arms around you, you should change your bad sleeping posture.

In the second trimester of pregnancy (4 ~ 7 months), attention should be paid to protecting the abdomen during this period to avoid the direct effect of external forces. If pregnant women have polyhydramnios or twin pregnancy, they should sleep in the lateral position, which can make pregnant women more comfortable. If pregnant women feel heavy lower limbs, they can take a supine position and slightly raise the lower limbs with a soft pillow.

In the third trimester of pregnancy (8 ~10 months), it is advisable to adopt the left lateral position, which can correct and increase the right rotation of the uterus, reduce the oppression of the uterus on the abdominal aorta and iliac artery, increase the blood supply to the fetus, and be beneficial to the growth and development of the fetus.
