Introduction

Causes of stillbirth generally include trauma, umbilical cord torsion, chromosomal abnormalities, etc. If a pregnant woman's abdomen suffers external impact, it may lead to premature placental abruption, causing the fetus to lose nutritional supply from the placenta and triggering abnormal uterine contractions, which could result in stillbirth. If the umbilical cord is excessively long, it may become entangled around the fetus during fetal movements, leading to umbilical cord torsion.

Common causes of stillbirth generally include trauma, umbilical cord torsion, and chromosomal abnormalities. The details are as follows:

1. Trauma

If a pregnant woman's abdomen suffers external impact leading to premature placental abruption, the fetus may lose its nutrient supply from the placenta and experience abnormal uterine contractions, which could result in stillbirth.

2. Umbilical Cord Torsion

If the umbilical cord is excessively long, it may become twisted or entangled during fetal movement, obstructing local blood flow. This can lead to fetal hypoxia and ischemia, potentially resulting in stillbirth.

3. Chromosomal Abnormalities

If either parent has chromosomal abnormalities, the fetus has a higher likelihood of chromosomal defects compared to normal fetuses. This may lead to fetal malformations, such as neural tube defects or gastroschisis, causing stillbirth.

In addition, gestational diabetes may also be a contributing factor. Pregnant women experiencing such conditions should seek timely medical treatment at a hospital to address symptoms appropriately. Delaying treatment is not advisable, and in severe cases, termination of pregnancy may be necessary.

Is there any impact if pregnancy is discovered after the husband received the third dose of the COVID-19 vaccine?

After the husband received the third dose of the COVID-19 vaccine, his partner became pregnant. The primary function of the COVID-19 vaccine is to act on the recipient's own immune system, stimulating antibody production. It does not enter reproductive cells nor alter genetic material. Antibodies or immune responses generated in men after vaccination are not transmitted to the fetus through reproduction. Currently, there is no evidence indicating that such situations increase the risk of fetal abnormalities.

Which has a greater impact on pregnancy: cytomegalovirus IgM or IgG?

Cytomegalovirus IgM has a greater impact on pregnancy, whereas IgG usually does not directly affect pregnancy and may instead provide immune protection. A positive IgM indicates recent or active infection, which could pose risks to the fetus; a positive IgG is typically an immunological marker of past infection. If IgM is positive during preconception or pregnancy, especially when accompanied by symptoms such as fever and fatigue,

Can two HIV patients have a healthy child?

If both partners strictly take medication before conception to continuously suppress the viral load below the detectable limit (typically requiring more than six months), and if the pregnant woman continues treatment as prescribed and implements mother-to-child transmission prevention measures during pregnancy, the probability of the fetus contracting HIV can be reduced to less than 1%, making it highly likely to give birth to a healthy child. Such cases must be managed全程 under the guidance of a professional medical team to ensure the safety of both mother and child.

Does elevated cytomegalovirus IgG have an impact on pregnancy?

If cytomegalovirus (CMV) IgG is elevated and IgM is positive, it may indicate a recent or reactivated infection. In pregnancy, this condition could allow the virus to cross the placenta and affect the fetus, increasing risks such as miscarriage and fetal malformations. Therefore, pregnancy should be postponed or closely monitored until IgM becomes negative before planning conception.

Can a 42-year-old get the HPV vaccine?

Vaccination with the HPV vaccine is not recommended for individuals with a history of severe allergies, allergy to any vaccine component, those experiencing an acute phase of illness such as fever or cold, or those who are pregnant. Allergic reactions may lead to serious consequences; vaccination during an acute illness may affect vaccine efficacy or increase bodily stress, and the effects of vaccination on the fetus during pregnancy remain unclear.

What is hepatitis B mother-to-child transmission?

Mother-to-child transmission of hepatitis B refers to the transmission of the hepatitis B virus from infected mothers to their fetuses or newborns during pregnancy, childbirth, or close postnatal contact. It is one of the major routes of hepatitis B transmission. If the mother is infected with hepatitis B virus, timely prenatal examinations and interventions are recommended. Transmission mainly occurs in three stages, during which the virus may pass through

Is a positive gonococcus test in pregnant women serious?

In general, a positive gonorrhea test in pregnant women is relatively serious, as it not only endangers the mother's health but may also affect the fetus. Immediate medical treatment following clinical guidelines is necessary. During treatment, medication should be taken in full dosage as prescribed, and self-discontinuation should be avoided to prevent recurrence. Personal hygiene should be maintained by frequently changing underwear, keeping the external genital area clean and dry, and abstaining from sexual intercourse. Regular follow-up tests are required to confirm clearance of the infection, and the diet should be light and nutritious.

Can pregnant women use amorolfine cream?

If a pregnant woman has mild infection symptoms or is in the first trimester (a critical period of fetal development), use of this medication is not recommended without clear guidance from a physician. There is currently insufficient research to confirm the drug's complete safety for the fetus; using it blindly may pose unknown risks. Moreover, due to increased bodily sensitivity during pregnancy, self-medication may easily cause skin irritation or other complications, potentially harming maternal and fetal health.
