Does smoking affect pregnancy?

Previously, only the majority of men smoked, but now, because of the respect for casualness and fairness, women have also begun to smoke and drink. In fact, scientific research has shown that it is good for men to smoke a small amount of cigarettes occasionally, but they should not smoke during pregnancy, especially women. So what effects does smoking have on pregnancy?

What are the effects of smoking on pregnancy?

Smoking has a huge link with infertility. The sudden changes in phenylalanine and anthracene caused by tobacco in the burning process are harmful to human cells. The sudden changes in the genetic factors of eggs and sperm can cause fetal malformations and mental retardation. Therefore, couples planning to get pregnant should quit smoking and drinking when preparing for pregnancy. Smoking causes a high incidence of congenital heart disease in babies. Smoking has a great impact on the fetus. Studies have found that typical carcinogens caused by cigarettes were found in the urine of children born to smoking women. The fetus digests and absorbs tobacco tar through the umbilical cord and converts it into carcinogens in the liver, which are eventually eliminated from the body through the kidneys, thus damaging the fetus's liver, kidneys and lungs.

Pregnant women smoking will also speed up the fetal heart rate and reduce respiratory activity. The tar and other toxic substances in the smoke can also penetrate into the embryo through the blood, be transported to the fetus, and even cause damage to the immature internal organs. Generally speaking, both parties should completely quit smoking and drinking when preparing for pregnancy for 3 to 6 months. In other words, if conditions permit, it is recommended that couples stop smoking six months in advance. In addition to quitting smoking and drinking, you also need to quit using tobacco and tar related products, including plasters or chewing gum. No matter what method you use to quit smoking and drinking, communicating with your doctor in time is very important for your success in quitting smoking. Your doctor may be able to tell you how other pregnant women successfully quit smoking or drinking, or at least provide you with much-needed encouragement.

Some people's early pregnancy reaction lasts longer and does not disappear until 16-18 weeks. During pregnancy, because the embryo and fur secrete a lot of estrogen and estrogens, under the joint stimulation of estrogen and estrogens, from the beginning of the early pregnancy, the fat layer of pregnant women thickens, blood flows into the mammary glands, stimulating mammary gland growth and causing the breasts to gradually expand. Enlarged mammary glands may cause the breasts to become enlarged, sensitive, and painful. The color of the nipples and nipples becomes darker, there are dark red lumps around the nipples, and a small amount of cold watery milk will continue to be secreted after 12 weeks.
