Heartburn is a common symptom of late term pregnancy during which up to 80% of pregnant women have experienced it by the end of their third trimester. [12] Heartburn often indicates the development of gastro-esophageal reflux disease (GERD), where the lower esophageal sphincter relaxes due to elevated progesterone levels causing increased ...
Pregnancy-induced hypercoagulability is probably a physiologically adaptive mechanism to prevent post partum hemorrhage. [1] Pregnancy changes the plasma levels of many clotting factors, such as fibrinogen, which can rise up to three times its normal value. [2] Thrombin levels increase. [3] Protein S, an anticoagulant, decreases.

According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
Healthy pregnancy results in a dense CMP which protects the uterine cavity from infection. [1] Elevated progesterone plasma levels induce cervical mucus to form a more viscous plug called the CMP. [7] One of the most common causes of preterm birth is inflammation induced by the changes in vaginal bacterial flora. [8]
[15] [16] It is estimated to affect 0.3–3.6% of pregnant women and is the greatest contributor to hospitalizations under 20 weeks of gestation. Most often, nausea and vomiting symptoms during pregnancy resolve in the first trimester, however, some continue to experience symptoms.
There are three purposes of prenatal diagnosis: (1) to enable timely medical or surgical treatment of a condition before or after birth, (2) to give the parents the chance to abort a fetus with the diagnosed condition, and (3) to give parents the chance to prepare psychologically, socially, financially, and medically for a baby with a health problem or disability, or for the likelihood of a ...
tert-Butyl alcohol is the simplest tertiary alcohol, with a formula of (CH 3) 3 COH (sometimes represented as t-BuOH). Its isomers are 1-butanol, isobutanol, and butan-2-ol. tert-Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor-like odor. It is miscible with water, ethanol and diethyl ether.
