Why does a pregnant woman need to go the toilet alot?

Increased blood volume: During pregnancy, a woman's blood volume increases by about 50%. This extra blood puts pressure on the kidneys, which causes them to produce more urine.

Relaxin hormone: The hormone relaxin is produced during pregnancy and it causes the muscles in the body to relax. This can weaken the muscles that control the bladder, making it more difficult to hold urine.

Growing uterus: As the uterus grows, it puts pressure on the bladder, which can also cause urinary frequency.

Constipation: Constipation is a common problem during pregnancy and it can also contribute to urinary frequency. When the bowels are full, they can put pressure on the bladder, causing the urge to urinate.

Drinking more fluids: Pregnant women are often advised to drink plenty of fluids to stay hydrated, which can also contribute to urinary frequency.
