Study Notes
Pregnancy Trimesters
- Pregnancy consists of three trimesters.
- The first trimester spans from 4 to 12 weeks, during which organs develop and the central nervous system (CNS) develops.
- The skeletal structure hardens from cartilage to bone around 4 weeks.
First Trimester Development
- Organ development occurs between 4 to 12 weeks.
Second Trimester Development
- Growth and development continue between 13 to 14 weeks.
- Teeth calcify around 20 weeks.
- The fetus can survive outside the womb around 24 weeks.
Third Trimester Development
- Growth and development continue.
- Storage of iron and other nutrients occurs between 36 to 40 weeks.
- Development of necessary fat tissue occurs between 36 to 40 weeks.
Weight Gain in Pregnancy
- Weight gain is small in the first trimester.
- Rapid weight gain occurs in the second trimester.
- Slower weight gain occurs in the third trimester.
- The average weight gain during pregnancy is 24 lbs.
Nutritional Problems
- Inadequate folate intake can lead to Neural Tube Defects.
- Folate and vitamin supplementation can help prevent Neural Tube Defects.
Pre-eclampsia
- Sudden weight gain after the 20th week of pregnancy may indicate water retention and possible onset of pre-eclampsia.
