What consequence can arise from the pressure of the uterus on the bladder during pregnancy?

During pregnancy, the growing uterus exerts pressure on the bladder, which can lead to increased frequency of urination. As the uterus expands, it takes up more space in the abdominal cavity, lowering the capacity of the bladder to hold urine. The increased pressure can trigger the urge to urinate more frequently, even if the bladder is not full. Additionally, hormonal changes during pregnancy may also contribute to increased renal blood flow and urine production, further intensifying the need to urinate.

This physiological change is common and is caused by both the mechanical effects of the uterus as well as the body's adaptations to pregnancy. As the pregnancy progresses, especially in the second and third trimesters, many women report needing to urinate more often, which can be uncomfortable but is a normal part of the physiological changes occurring in the body.
