Common urinary problems during pregnancy include bladder infections, urinary incontinence and an increased urge to urinate, states WebMD. An increase in frequency of urination is also a common problem for pregnant women, reports BabyCenter.
A frequent need to urinate can begin as early as six weeks into a pregnancy, notes BabyCenter. This is caused by hormonal changes that push blood more quickly through the kidneys, causing the bladder to fill more frequently. Further into the pregnancy, pressure from the growing uterus can add to the problem. Hormonal changes and pressure on the bladder also lead to an increased urge to urinate, explains WebMD.
An expanding uterus and shifting hormones can trigger bladder and kidney infections in pregnant women, particularly in the second trimester, according to Mayo Clinic. Bladder infections can make it difficult or uncomfortable to pass urine. While common, bladder infections should be taken seriously, because they can increase the risk of kidney infections, premature birth and miscarriage, cautions WebMD.
Urinary incontinence can be an issue both during and after pregnancy, according to WebMD. During pregnancy, incontinence is often the result of pressure on the bladder. After pregnancy, it can occur due to the weakening of pelvic floor muscles during childbirth.
