Pregnant women are not more likely than others to get a bladder infection, though if one occurs, there are more chances that it will travel to the kidneys. According to some unconfirmed reports, about 3 to 4 percent of all pregnant women develop a urinary tract infection.

According to doctors, frequent hormonal changes and shifts in the position of the urinary tract during pregnancy make it much easier for bacteria to travel up the urethra to the kidneys than under normal conditions. Due to this reason, it is recommended that the urine of pregnant women be tested periodically.

A pregnant woman who develops a bladder infection needs prompt treatment to avoid premature delivery of her baby and other risks such as high blood pressure. Moreover, it must be kept in mind that some antibiotics are not safe for use during pregnancy. Various factors need to be considered before finalizing the treatment, such as the drug's effectiveness, the stage of pregnancy, the mother's health, and potential effects on the fetus.

Bladder infections during pregnancy require immediate attention and should never be ignored. The infection can become especially complicated by blockage of normal urinary flow and infection elsewhere in the body. It can also become complicated by alarmingly low blood pressure. Any medical conditions during pregnancy that impair the normal urinary flow, such as kidney stones or diseases of the nervous system leading to bladder weakness, can lead to more complicated and severe bladder infections. If the root cause of the infection goes untreated, this group of patients is at risk of kidney damage.
