In addition, hormones also stimulate the kidneys to work more and produce more urine to help the body get rid of excess waste faster. When pregnant, the rest of the fetus's metabolism in the womb is also excreted through the urine in the mother so that blood flow and urine production in pregnant women increases. In pregnant women, blood volume has increased to nearly 50 percent from before pregnancy. This means a lot of extra fluid has to be processed in the kidneys and ends up in the bladder. In addition, the enlarged uterus puts pressure on the bladder. And when the fetus in the womb grows and grows, his weight can suppress the bladder to make pregnant women have to urinate continuously, especially in the first trimester and last trimester of pregnancy.
