Study Notes

Reproductive Development Terms

Implantation is the process in which the blastocyst attaches to the uterine lining.
From the 9th week of development until birth, the term "fetus" is used to describe the developing offspring.
After 5 weeks of development, the placenta takes over the role of nourishing the embryo.
Gestational diabetes is the condition characterized by high blood glucose levels during pregnancy, especially in the third trimester.
Fertilization of the egg occurs in the fallopian tubes.
The zygote is the single-celled structure produced by the fertilization of the egg.
Before the 9th week of development, the term "embryo" is used for the developing offspring.

Maternal Changes During Pregnancy

The placenta promotes uterine growth, relaxes muscles and ligaments to accommodate the growing fetus, and increases fat deposition during pregnancy.
The blastocyst embeds into the endometrium of the female reproductive system.
Maternal blood volume increases significantly during pregnancy to support the developing fetus.

Nutritional Needs During Pregnancy

The condition in which the early embryo receives nourishment by breaking down the uterine lining is called "decidualization."
After 5 weeks, the placenta assumes the nourishment role for the embryo.
The recommended additional daily energy intake during the 2nd and 3rd trimesters of pregnancy is approximately 300-500 calories.
An additional 10-20 grams of protein per day is recommended during the 2nd and 3rd trimesters of pregnancy.
An increase of about 175-300 grams in daily carbohydrate intake is recommended during pregnancy.
Omega-3 fatty acids, particularly DHA, are vital for brain and eye development in the growing fetus.
The recommended increase in daily water intake during pregnancy is about 8-10 cups to stay hydrated.
The recommended increase in daily iron intake during pregnancy is approximately 27 mg to support increased blood volume.

Health Implications

Excess weight during pregnancy can lead to increased postpartum weight retention, complicating recovery.
Impaired metabolic health of the mother during pregnancy can lead to complications such as gestational diabetes and preeclampsia.
Physiological changes during pregnancy, such as hormonal fluctuations and weight gain, can cause side effects like nausea, fatigue, and heartburn.
Low folate intake during pregnancy can increase the risk of neural tube defects in the developing fetus.
Iodine deficiency during pregnancy can lead to cognitive impairments and developmental delays in the child.
Zinc deficiency during pregnancy can affect fetal growth and immune function.
