Hypertension-induced pregnancy (p-PHI)

A condition during pregnancy where high blood pressure develops, potentially affecting both the mother and the fetus.

Gestational Trophoblastic Disease

A group of conditions that occur when a fertilized egg doesn't develop into a normal pregnancy but instead grows abnormally in the uterus.

Chromosomes and DNA

The genetic makeup of an individual, determined by the arrangement of chromosomes and the DNA they carry.

Study Notes

DNA, Genes, and Chromosomes

  • DNA is a double helix structure.
  • Chromosomes are long strings of DNA.
  • Humans have 23 pairs of chromosomes (46 total).
  • Chromosomes are made up of 4 parts: adenine, thymine, guanine, and cytosine.
  • Males have XY chromosomes, females have XX chromosomes.

Pregnancy Complications

  • Pregnancy-related hypertension (pre-eclampsia) can impact a pregnant woman's health.
  • Several factors influence pregnancy complications, including pre-existing conditions, age, lifestyle, and current pregnancy issues.
  • Complications may impact the developing fetus.
  • Monitoring and management of complications during pregnancy are crucial.

Gestational Trophoblastic Disease

  • Gestational trophoblastic disease is a condition where abnormal cells grow in the uterus during pregnancy.
  • It's a type of abnormal uterine growth during pregnancy.

Ovulation and Fertilization

  • Ovulation is the release of an egg from the ovary.
  • The nearest day of ovulation is important in determining conception.
  • Factors like foreplay time, position during sex can alter conception prospects.

Prenatal Conditions and Health

  • Pre-existing health conditions can impact pregnancy.
  • Lifestyle choices also affect pregnancy's health outcome.
  • Age plays a role in the likelihood of pregnancy complications.

Monitoring Pregnancy

  • HCG levels can be measured throughout pregnancy.
  • HCG levels may differ between the first and last trimesters.
  • Changes in HCG levels could signal various conditions.

Pregnancy Hypertension

  • Conditions like pregnancy-induced hypertension could impact the mother's well-being.
  • Various factors contribute to the potential for this condition.
