What is a common symptom that returns during the third trimester?

Urinary frequency is a common symptom that often returns during the third trimester of pregnancy. This occurs due to several physiological changes. As the uterus expands significantly in the third trimester, it exerts pressure on the bladder, reducing its capacity to hold urine. Additionally, hormonal changes, particularly increased levels of progesterone, can also influence bladder function and contribute to a more frequent urge to urinate.

Throughout the third trimester, women may find themselves needing to urinate more frequently, even if they have not consumed significantly more fluids. This symptom can be particularly disruptive during the night, leading to sleep disturbances due to the need to wake and use the restroom.

Other symptoms listed, such as decreased appetite, increased energy levels, and decreased need for sleep, do not typically correspond with the physiological changes and experiences of women in the third trimester, making urinary frequency the most relevant and common symptom during this time.
