What significant change can be anticipated in a pregnant woman's body during the third trimester?

During the third trimester of pregnancy, one significant change that can be anticipated is alterations in sleep patterns. As the pregnancy progresses, many women may experience discomfort due to physical changes such as the growing size of the abdomen, which can make it challenging to find a comfortable sleeping position. Hormonal changes and increased anxiety related to the impending birth can also disrupt sleep. Additionally, frequent urination can occur as the weight of the uterus exerts pressure on the bladder, further complicating sleep quality. Recognizing and addressing these changes is crucial for promoting better sleep hygiene and overall well-being during this phase of pregnancy.

Other options do not accurately represent the common experiences during the third trimester. For instance, increased energy levels typically occur in the second trimester, while regular episodic headaches are not universally experienced and can vary significantly among individuals. Improved metabolism is also not usually noted as a significant change during the third trimester; instead, many women may experience a slowing of metabolism as their bodies prepare for labor and postpartum recovery.
