Everyone knows pregnant women need to pee all the time. It has become a bad joke.
I bet you didn’t know that urine smell and color can change during pregnancy though. This doesn’t really affect how much you urinate, but it’s just interesting.
So now we get to the urinary frequency changes of pregnancy. Urinating more than 7 times per day is considered “frequent”. Getting up from bed at night to pee, called nocturia, is defined as 2 or more times at night. These symptoms affect 80-95% of women at some point during pregnancy. So yes, they are extremely common.
The frequency in urination is considered “multifactorial”, which means there are many different factors, and we don’t know all of them. We know there is an overall increase in urine output during pregnancy, which makes you urinate more often. We know later in pregnancy the uterus does compress the bladder, which makes you feel like you have to pee all the time. But women notice increases in urination as early as 5-6 weeks, and the uterus is not compressing anything at that point (it’s barely bigger than normal), so we know the uterus pushing on the bladder is not the only culprit.
Nocturia causes include the same reasons – if you have to pee more often, that includes at night too. Later in pregnancy, when you are nice and swollen, your doctor will tell you to rest and put your feet up. This happens at night when you sleep. The swelling goes down, and that extra fluid – where does it go? Through your kidneys to your bladder.
My last (and most distressing) urinary change in pregnancy is about incontinence … aka you can’t hold your urine and you pee yourself. Urinary incontinence in pregnancy is caused by several things: once again, the uterus presses on bladder, making the bladder harder to control; there are hormonal effects on the urethra (your pee hole, in case you didn’t know the medical term), making you unable to control the flow from there as well. The bad news here is that incontinence during pregnancy is associated with worse, persistent incontinence after you have the baby too. There are exercises and surgeries to help with this problem, but it’s embarrassing and really uncomfortable in the meantime.
So now you know a little about procreation affecting your urination. Hot topic. Glad I could help.
