Urination is considered frequent if the urge to it occurs more than 9 times a day. It can be up to 20 times in pregnant women. The symptom of frequent urination begins to manifest itself with an increase in hCG in the blood.

This action of the hormone contributes to a decrease in the tone of the bladder and its more frequent emptying. Sometimes frequent urination can be a symptom of a serious infection rather than a sign of pregnancy.

Why Frequent Urination happens in Pregnancy?

The primary reason for the onset of increased urination is associated with an increase in hCG in the blood. Its high concentration stimulates the production of progesterone, which relaxes the muscular organs, including the bladder. Its tone decreases and this causes frequent emptying.

Another reason for the frequent urge to have bowel movements is increased blood circulation in the pelvic area. The load on all organs and systems of a woman is growing. The kidneys begin to function for two in the first weeks of pregnancy. This increases the amount of urine produced.

Frequent urination at a later date is a consequence of the restructuring of the internal organs and an increase in uterine pressure. The bladder is no longer able to fill. Not a typical and not healthy cause of frequent urge to urinate in the presence of infectious diseases: cystitis, pyelonephritis, urethritis.


You can protect yourself from the already existing frequent urination by adjusting the drinking regimen, gentle medications, proper nutrition, and hygiene measures. Prevention is the most effective. The problem can be reduced as much as possible if it already exists. Here is an example of the most obvious means of helping to reduce frequent urination during pregnancy:

Drinking schedule

Remove caffeine and other provocative drinks

Coffee, cola, soda, and juices strongly stimulate the kidneys. Urine is excreted much more than usual. It is best to remove these drinks from your list during the symptomatic period to reduce the urge to urinate symptom.

Protected sex

Use contraceptives during intercourse during pregnancy. This greatly reduces the risk of developing sexually transmitted diseases. Infections cause increased urine production. This complicates the course of pregnancy and leads to unpleasant symptoms during urination.
