Introduction to the harm of smoking to pregnant women

Smoking is harmful to health. I believe everyone knows this sentence, but in real life, many people are addicted to smoking, and it is not easy to quit smoking. For pregnant women, smoking is more harmful and will directly affect the health of the fetus and cause irreparable harm. Next, we will introduce to you in detail the harm of smoking to pregnant women.

1. Can cause sperm abnormalities

Studies have shown that for men who smoke more than 30 cigarettes a day, the proportion of abnormal sperm exceeds 20%, and the longer they smoke, the more abnormal sperm they have. Sperm will return to normal six months after stopping smoking. If one or both spouses smoke regularly before pregnancy, the harmful components in tobacco will enter the reproductive system through the blood circulation and cause direct or indirect toxic effects.

2. Damage to fetal DNA

Diana Anderson, of the School of Life Sciences at Radford University in England, said it takes three months for a reproductive sperm cell to fully mature, so men need to give up smoking long before their partners become pregnant to avoid genetic problems.

3. Lead to premature birth of the fetus

Studies show that 10% of sudden infant deaths worldwide are caused by secondhand smoke. Most of the harmful chemicals released when tobacco burns can pass through the placenta to "harass" innocent babies. Toxic gases such as carbon monoxide can reduce the oxygen concentration in the mother's blood, leading to fetal hypoxia; nicotine, the addictive drug in tobacco, can cause blood vessel narrowing and slow blood flow, which means that the nutrition and oxygen provided to the fetus will be reduced, which can easily cause premature birth.

4. Vulnerable fetal intelligence

Research results show that nicotine in cigarettes can cause placental vasoconstriction, reducing blood supply to the fetus and causing fetal hypoxia. The carbon monoxide in cigarettes can cause fetal hypoxia, resulting in fetal maldevelopment or even stillbirth. The cyanide in cigarettes combines with a substance called sulfur amino acid in the human body, which can reduce the amount of vitamin B12 in the body, thereby affecting the development of the fetus and causing the child to be born with mental retardation.

The above content is an introduction to the harm of smoking to pregnant women. The physical condition of pregnant women themselves is relatively special, so everyone must pay attention to these contents in life. Pregnant women have very special requirements for their living environment and diet during pregnancy. If any discomfort symptoms occur, you must go to the hospital for examination in time.
