No matter what type of abortion procedure is invasive, women are advised not to choose abortion lightly. Modern people are not as conservative about sex as they were in the past, and the time to have sex is getting earlier and earlier, and the number of unmarried abortions is rising. According to the national statistics, there are nearly 5 million unmarried abortions each year. However, these female patients do not know that there are great health risks behind the abortion procedure. For some women, they may think that having a medical abortion is more convenient and does not require intrauterine surgery, which reduces pain and the chance of infection in the uterine cavity. However, they do not realize that the serious consequences of an incomplete medical abortion are too much for any woman to bear. Medical abortion is not an option for everyone. It has narrow indications and is a form of abortion for those who have a small pregnancy. Theoretically, abortion can only be performed within 7 weeks of pregnancy. However, there are some women who need to determine if they can have a medical abortion based on the size of the ultrasound due to early ovulation. If the ultrasound reveals that the gestational sac is within 2 centimeters, then a medical abortion is an option; however, if it is more than 2 centimeters it is not recommended. The reason is that a gestational sac of more than 2 centimeters may cause an incomplete medical abortion. About 20-30% of women who choose to have a medical abortion will have an incomplete medical abortion, which means that 2-3 out of 10 medical abortion patients will have an incomplete medical abortion, and the consequence of an incomplete medical abortion is to have an abortion. The miscarriage is prone to infection or infertility Miscarriage is also known as the “small month”, which shows the deep impact of miscarriage on the human body. What are the serious consequences for the human body if the abortion is not handled properly? Whether or not an abortion will leave sequelae is closely related to the operating doctor. If you choose to go to a regular hospital for the procedure, there will be relatively few post-operative complications. This is because the doctors in big hospitals are more skilled and experienced, and the incidence of incomplete abortions is lower. Some small clinics, on the other hand, have relatively inexperienced doctors with many complications, and improper surgery may result in perforation and infection. Infertility and medical or human abortion are closely related. If there is infection before the operation, the doctor operates without treatment or the patient asks for medical or human abortion without examination, plus the patient does not take oral antibiotics on time and pay attention to contraception, it can cause reproductive tract infection and secondary infertility. Therefore, women are advised to take good care of their uterus, pay attention to contraception, and not to choose abortion easily.
